1.      If you are diagnosed with anal cancer, you must get a diet chart prepared for you that will help you in managing anal cancer.  Anal cancer patients must consume a diet rich in omega-3 fatty acids, monounsaturated fats, lean protein, fresh fruits and vegetables and whole grains. Anal cancer patients often suffer from extreme weight loss; the weight loss can be side effect of the treatments undergone by the patient and might also occur due to metabolic demands of the disease.  Weight loss in anal cancer patients occurs primarily because of the loss of muscles and tissues. Taking a diet rich in the above mentioned food items and nutrients will help in preventing the tissue loss and muscles wastage.

2.      The most common treatment procedures used for managing anal cancer are chemotherapy and radio therapy. These therapeutic procedures may be carried out after a surgery for removing the cancerous tumors; the physician might recommend surgery to patients both in early and advanced stages of anal cancer depending on this overall health conditions.

3.    Once the treatment of anal cancer is over and the cancer is cured, the main focus of the doctor is preventing recurrence of the disease. For this one must consume a balanced diet regularly after the surgery. Even if you are declared to be completely free from the cancer, you should eliminate certain food items from your meal permanently or decrease their intake significantly. Some such food items are: foods containing saturated fats, sugar, refined flour, processed meats etc. According to medical experts a patient recovering from anal cancer, must consume at least 5 servings of fresh vegetables and fruits. This will help them in maintaining a healthy digestive system and will also act as the source of all the essential minerals and vitamins.

The Vaccines and Related Biological Products Advisory Committee conducted a reassessment of the Gardasil vaccine which has earlier the approval as an inoculation against cancer of the cervix & genital wart formations.

Speaking in detail about the trial outcomes forwarded by the firm, one of the members of the United States Advisory Panel, Prof. A. Cheung considers that the basis for supporting the Gardasil vaccine exists and the information quite strong.

The Food and Drug Administration generally has been observed to accept the proposal put forth by its review board, although it is not needed to be doing it.

The FDA advisers didn’t obtain any vote on the vaccine, however majority stated that Gardasil vaccine was found to be effectual in firm trials.

The company put forth information which tested the vaccination among males, however several people from the panel stated that they were certain that the product additionally can offer protection to females from anal cancer.

The FDA would be considering the board’s inputs when arriving at the decision to whether to back Gardasil for inoculating both genders in the age band of nine years till twenty-six years for anal cancer prevention.

Gardasil is presently vended for younger females for preventing cancer of the cervix & averting genital wart formations among boys & guys. It combats infection caused by the virus HPV or human papilloma virus through sexual contact, mostly identified as the chief reason for cervical cancer. The virus is also the main offender in causing anal, penile, head & neck cancers.

Anal cancer is a comparatively uncommon type of cancer affecting around five thousand individuals annually in the United States, though the numbers of cases identified are rising at a pace of two percent each year for the previous thirty years. The deaths due to anal cancer are also rising. It has been found in developing nations wherein collection of such form of information has been done.

Males engaging in sexual intercourse with males are the ones mostly identified with anal cancer as compared to the other populace; however, in regards to the general figures, increasingly more females are getting anal cancer as compared to males and accounting for around sixty percent of the cases.

Cervical & anal cancers are basically the analogous condition when taking into consideration the causes. Both of these have strong links to a number of different forms of HPV infections.

Moreover, anal cancer among males even seems to be analogous as the disease in females and researchers have not yet uncovered any proof of underlying sex differences. Such resemblances were the main constituents of the advisory committee’s support for Gardasil vaccination since Merck has solely done the efficacy test for anal cancer prevention in just males.

Gardasil was earlier viewed as a prospective huge seller for the firm, however sales have reduced in the midst of business-competition from arch contender GSK product & since several younger females have already received Gardasil vaccination it has limited the market volume. Just last year, sales of the vaccination knocked slightly over a billion dollars globally.

According to a speaker for Merck, the FDA’s verdict is anticipated by this year’s conclusion on the usage of vaccine for anal cancer prevention & averting cancer of the cervix among females in the age band of twenty-seven to forty-five years old.

• Other types of cancer

  There is a much higher risk of acquiring this form of cancer in male patients that have previously suffered from the affects of penile cancer, and it is also higher in women that have previously had cervical or vaginal cancer.

• Human papilloma virus (HPV)

  There are as many as 80% of the individuals that suffer from HPV, that also end up suffering from the symptoms that are commonly associated with anal cancer.

• An individual’s age

  Age is a factor that greatly affects the causes of anal cancer, as well as various other types of cancer. The older an individual becomes, the higher their chances become in acquiring this disease.

• Cigarette smoking

  Individuals that develop the unhealthy habit of cigarette smoking are much more likely to acquire anal cancer than in individuals that do not smoke.

• Anal lesions that are benign

  Benign anal lesions can be caused from various health conditions such as irritable bowel disease (IBD), cicatrices or fistulae, and hemorrhoids. These lesions can cause the risk to become higher in individuals with this type of problem.

• Several sex partners

  HPV is a common health condition that individuals with several sexual partners can acquire, which is also a health concern that is linked to cases of anal cancer.

• Immune system that is weak

  A weakened immune system is one of the common causes of anal cancer, and a variety of other types of diseases and health conditions as well. People that make it a point to eat healthy, get plenty of rest, and consume meals that are high in vitamins and mineral content, are much less likely to suffer from the problems that a weakened immune system can cause.

• Anal sexual intercourse

  Any individual that engages in anal sex are risking a much higher chance of acquiring anal cancer, than those that do not participate in this type of sexual activity. The risk in men that engage in this type of sexual activity that have been diagnosed as being positive with HIV, the chances of acquiring anal sex is as much as 90 times higher than in those without this disease.

To ensure that you do not end up suffering from the painful symptoms that can occur when an individual has, it is important to become aware of the causes of anal cancer.  Leading a healthy life is also important and can be achieved by eating healthy foods that contain essential vitamins and minerals that the body needs to function properly. Plenty of rest and exercise are also very important for good health.

• There are many people with this disease that begin to notice a discharge that is jelly-like in its consistency and is expelled from the anus.

• Women with this disease may notice a dryness of the vagina.

• Bleeding of the rectum is one of the common symptoms of anal cancer that many people notice as they are wiping after using the restroom, and some people notice it in the stool.

• Because tumors associated with this type of cancer can often form on the vagina, many women notice a great deal of back pain with this disease.

• Most all people that suffer from this disease will experience pain that is felt in the anal area.

• Itching of the anal area is a very common occurrence with this type of disease.

• Some individuals with anal cancer experience uncomfortable bloating.

• Lumps that can be felt in the anus area is one of the common symptoms of anal cancer that are many times mistaken for hemorrhoids (piles).

• A mucus discharge that is discharged from the anal area is a problem that many anal cancer patients end up dealing with.

• Fecal incontinence is a common problem that many individuals experience, which is more commonly known as problems in being able to control the bowels.

• Some individuals may experience various changes in how the bowel movements occur. These changes would include stools that are much thinner, constipation, and problems with diarrhea.

When these types of symptoms are experienced, it can become extremely hard for a person to handle the pain and discomfort that they are going through. However, there is a wide variety of prescription medications that many physicians and specialists will prescribe to patients that regularly experience the many symptoms of anal cancer.

If you begin noticing any of the above listed types of symptoms, you should not become alarmed. The most important thing that you will want to do is make an appointment with your family health care provider so that he can gather information on your family history, and schedule the appropriate tests that will need to be done for an adequate diagnosis. There are some of the symptoms of anal cancer that do occur in various other types of health conditions, so just because you may be experiencing one or two of these symptoms, it does not necessarily mean that you are suffering from anal cancer.

According to the National Cancer Institute, there are as many as 5,000 individuals every single year that are diagnosed with this specific type of cancer. However, the occurrence of this specific type of cancer has shown to be on the rise, but the reason why there has been an increase in people that acquire anal cancer is still unclear.

Aside from the question ‘what is anal cancer’, another question that concerns many individuals is when does this type of disease generally occur, what symptoms are usually experienced when a person has anal cancer, and what are the most common treatment methods that are used for this specific type of cancer.

In most of the cases when a diagnosis ultimately leads to the occurrence of anal cancer, the disease is generally found when it is in its early stages. This is of course a huge benefit to the patient, as early treatment offers the highest chances of being able to adequately cure the disease.

There are a variety of different factors that can ultimately end up causing a person to suffer from anal cancer. Some of the most common factors that various studies and research projects have uncovered are those that are listed below.

• Smoking cigarettes containing nicotine puts individuals at a much higher risk for acquiring this form of cancer.
• Individuals that engage in sexual activities with several different sex partners in combination with anal sex can result in this disease.
• Individuals that have reached the age of 50 and above are at a higher risk for anal cancer.
• Due to the sexual activities of individuals that are homosexual, their chances of acquiring anal cancer are much higher than in individuals that are heterosexual.
• Individuals who have acquired HPV, which is more commonly known as genital human papillomavirus are at a much higher risk level for acquiring problems that are commonly associated with anal cancer.

Followed by the question of ‘what is anal cancer’, those who have acquired this type of disease are at a much higher concern of the specific treatment methods that are commonly used to treat this type of disease. Because most cases of anal cancer are caught early, there is a high success rate of successfully being able to treat and cure individuals that have acquired this form of cancer.

Treatment could be offered for varying reasons and the apparent advantages would differ in each individual. In case the treatment is being given with the objective of curing the cancer, the decision on whether to undergo the treatment might not be that tricky. But, when the cure is not achievable and the treatment is for controlling the cancer for a span of time then it could get knotty reaching a decision on whether or not to undergo the treatment.

In case one is undecided regarding the treatment when initially explicated, one could always request for additional time to make up one’s mind.

The choice not to undergo the treatment is an individual decision and the staff could elucidate what could imminently occur in case one does not want to get treated.

HIV and Treatment

Individuals having depleted immunity due to HIV along with having anal cancer might experience increased intensity of side effects during and subsequent to the treatment. As a consequence, the radiotherapy amounts and chemotherapy doses might be lowered.

Radiotherapy

Radiotherapy employs the use of high-power energy beams for obliterating cancer cells, while sparing most of the normal cells. The treatment is mostly administered for a certain span of minutes during every weekday lasting till four to six weeks.

During the course of the treatment phase, the patient would experience alterations in bowel functioning like diarrhoea or would pass wind often; though these side effects could at times be lowered by keeping away from some foods. As one approaches the concluding phase of the treatment, one could start getting blisters or tenderness in the skin around the anal area or also likely in groin parts. Intense weariness or exhaustion is additionally a prevalent side effect of undergoing radiotherapy treatment for anal cancer.

Such side effects generally subside in a gradual manner as the treatment concludes, though it might require few months for the skin to come back to its normal form. Some individuals experience a long-lasting change in their bowel movements. It is imperative to speak with one’s doctor or specialist nurse regarding this as mostly there are ways to allaying these problems. The doctor or dietician at the hospital could provide further guidance.

Other likely side effects that might arise subsequent to radiotherapy for anal cancer are vaginal constriction (vaginal stenosis) and dryness felt in the vagina. To aid in averting this, women would be advised on using vaginal dilators alongside jelly for lubrication purposes for keeping the vaginal walls open and maintain suppleness. Few women might also require using lubricating jelly at the time of sexual contact.

Infertility (inability to bear children) could be the consequence of undergoing radiotherapy. In case one is apprehensive about the chances of infertility subsequent to treatment, then it would be a better option to discuss this matter with the specialist prior to commencing the treatment.

Chemotherapy

Chemotherapy employs cancer-combatant (cytotoxic) drugs for annihilating cancer cells that are administered generally through intravenous injection.

Chemotherapy could transitorily lower the normal cell count in the blood. One could become more prone to infection when the white blood cell count depletes. When there is a plummet in red blood cell count, then a person could turn anemic leading to recurrent fatigue. A sapped platelet count could lead to easy bruising. The blood would be analysed on a regular basis during the course of chemotherapy treatment and antibiotics could be suggested for treating any kind of infection. Blood transfusion could be administered in case one gets anemia during the course of chemotherapy.

Other side effects experienced involve feeling nauseous and vomiting. Oral sores and ulcers could arise as side effect of certain chemotherapy drugs. Regular use of mouthwashes is vital and the nurse would illustrate on their optimal use.

In case one has no appetite for consuming meals, then nutritive beverages or soups could be employed as supplements in the diet. Wide-spanning choices of beverages are obtainable at many chemist shops. The doctor or dietician could be consulted regarding diet queries.

Surgery

Surgery is chosen when the original treatment fails to totally eliminate the cancer or when there are symptoms of a relapse. There are two key forms of surgery:

Local Resection
This could be employed for small-sized tumours located outside the anus. This surgery solely involves the removal of the part of the anus that has the malignant growth. The anal sphincter is generally not affected, and hence there is normal bladder functioning retained in majority of the individuals.

Abdominoperineal Resection
This involves removing the anus and rectum. A permanent colostomy is requisite in this surgery wherein a diversion is made from the open end of the bowel onto the abdominal surface for allowing passage of the faeces outside of the body ending in a colostomy bag. The aperture on the wall of the abdomen is called a stoma. The perception about a colostomy could be firstly disquieting and upsetting for several individuals, though many get accustomed to it over a span of time and could go back to their normal functioning.

Anal Cancer is a condition that develops in the tissues present in the anus. Anus is the small tubular structure connecting the lower section of the large intestine called the rectum to outside the body. The anus functions by controlling the excretion of unwanted body waste through bowel movements.

Diagnosis & Tests:

The general practitioner would carry out a detailed examination of the patient subsequent to which, the patient would be referred to a professional in bowel conditions –the gastroenterologist. In the hospital, the doctor would query the patient regarding general health conditions and any past medical conditions. The patient would be examined by the doctor and blood sample would be drawn for checking the general health and the functioning of the liver. A series of tests would be conducted for confirming the presence of anal cancer.

• Rectal Exam
  At times also called the PR exam wherein the doctor would conduct an examination of the back route with a lubricated gloved finger.
• Biopsy
  A small amount of cell sample is drawn from the tumour for microscopic analysis. Generally, this employs the use of either a specialised biopsy piece of equipment called the punch biopsy or a small section of the tumour would be incised by the doctor – called the incisional biopsy. Both of these biopsies are conducted under the influence of local or general anaesthesia. In case the tests reveal an affirmative outcome, then additional tests would be carried out to analyse the metastasis of the cancer.
• X-Rays
  These are taken for assessing whether the cancer has metastasized.
• Ultrasound Scan
  This simple scanning procedure employs sound waves for capturing images of the interior of the abdominal region that are conducted in the hospital scanning section. On lying down on a flat surface, a gel is applied all over the abdomen subsequent to which a small hand-held device is moved all over it. The sound waves produced are transformed into images employing a computer. The pain-free procedure lasts for nearly twenty minutes. At times an ultrasound scan procedure called as endoanal ultrasound could be performed wherein a tiny, slender probe is introduced into the back route (rectum) that provides images of the size and spread of the tumour.
• CT or Computerised Tomography Scan
  A CT scan captures a sequence of x-rays that are passed via computer to reproduce 3-D pictures of the inner areas of the body. The pain-free procedure lasts for ten to thirty minutes. CT scans employ miniscule amounts of radiation that are not harmful to either the patient or those coming in contact with the patient. The patient would be requested not to ingest liquids or solids for nearly four hours prior to the scan. Majority of the individuals undergoing the scan are offered a drink or administered a shot for allowing certain areas to be seen more lucidly. Prior to getting the injection or the drink it is imperative to inform the individual conducting the test whether one is allergic to iodine or asthmatic. Following the scan, one could return home.
• MRI or Magnetic Resonance Imaging Scan
  This test procedure is analogous to a CT scan, however this employs magnetic fields rather than x-rays. During the course of the scan, the person would be requested to lie totally motionless on a couch inside a metallic cylindrical enclosure which is a potent magnet. Hence, prior to entering inside the room, one must remove any kind of metallic items in one’s possession. The doctor also must be informed in case one has previously worked with metals or were employed in the metal industry or whether one has any metal present in the body (for instance, a heart monitor, a pacemaker, surgical clips or bone pins). In case these might be present in the body, then a MRI would not be performed on that person due to the magnetic fields. An injection would be administered for allowing greater picture clarity of the interiors of the body. The test procedure would last for nearly thirty minutes and is totally painless, though the MRI machine could sound loud. Earplugs or headphones would be offered for this reason. In case, one is apprehensive of closed spaces, one might find the feeling of being inside the machine quite suffocating or stifling. A 2-way intercom facilitates easy communication with the person operating the scanner.
• Staging and Grading
  The staging of cancer depicts the size and the extent of metastasis past the initial location of occurrence. Gaining knowledge of the specific type and the staging of the cancer assists doctors in deciding upon the best line of treatment. Cancer could proliferate in the body through either the bloodstream or via the lymphatic system. The lymphatic system is a component of the body’s protection mechanism from infection and ailments and comprises of a system of lymph glands or lymph nodes that are connected by fine ducts that contain lymph fluid. The doctor would generally examine the close by lymph nodes while staging the cancer.
• Stage 1
  The cancer is observed to affect the anus and has a size of lesser than two centimetres or 3/4th inch. It has not yet metastasized to the sphincter muscle.
• Stage 2
  The cancer is more than two centimetres in size, however has not reached into the close by lymph nodes or to other body parts.
• Stage 3A
  The cancer has metastasized to the lymph nodes near the rectum, or to the closely situated organs like the bladder or vagina.
• Stage 3B
  The cancer has metastasized to either the lymph nodes in the groin region, pelvis or to the lymph nodes near the anus, along with the closely placed organs like the bladder or vagina.
• Stage 4
  The cancer has metastasized to lymph nodes in the abdominal region or other organs of the body like the liver.At times, a different staging system known as the TNM staging system is employed in place of the number system specified above.

   

  • T
    Depicts the tumour size and if it has spread to the close by organs.
  • N
    Depicts if the cancer has metastasized to the lymph nodes.
  • M
    Depicts whether the cancer has metastasized to another body organ like the liver (secondary or metastatic cancer).

Though this system is more multifarious, it could offer more accurate data regarding the tumour staging.

In case the cancer relapses subsequent to original treatment, then it is called as recurrent cancer.

Grading

Grading refers to the microscopic appearance of the cancerous cells and provides insight about how rapidly the cancer could develop. Low-grade would mean that the cancer cells appear quite alike normal cells. They generally have a slow growth and are less prone to proliferating. Among high-grade tumours, the cells appear quite anomalous and have a likelihood of swifter growth and spread.

An anal cancer diagnosis conducted annually in the UK revealed roughly eight hundred patients in a total populace of 61 million (2009). According to an estimate provided by the American Cancer Society, nearly 5,070 newly emergent anal cancer cases were detected in the U.S. in 2008, from which nearly sixty percent were of women. Majority of the anal cancer patients are identified in the age group of early sixties. In 2008, nearly 680 individuals died due to anal cancer in the U.S. having an estimate populace of nearly three hundred million in 2009. Reports have cited that this form of cancer is on a perennial upswing in both sexes especially among U.S. men. A varying drift in sexual practices – merged with usage of tobacco and infection due to a particular HPV or human papilloma virus strain are amongst the reasons behind this surge.

Anal Cancer is prevalent among that populace of both sexes that freely consented to anal intercourse and among individuals with depleted immune systems. Experts have stated that anal cancer is closely related to few strains of HPV.

The anus, anal canal and the Squamous Cell Carcinomas

The anus lies at the end of the GI or gastrointestinal tract while the anal canal is the interconnecting tube between the rectum and the outside part of the body. The anal canal is delimited by the sphincter – a muscle with its contraction and relaxation action is responsible for controlling bowel movements.

The squamous cells are flat and fish-scale like in appearance, forming a lining inside the anal canal. Most of the anal cancer cases developing from these squamous cells are called squamous cell carcinomas.

The spot where the anal canal gives way to the rectum is known as the transitional zone. This zone is lined by squamous cells and glandular cells that produce mucus thus providing lubrication for easy passage of stool or feces. Adenocarcinoma – a cancerous form affecting the anus could arise from the glandular cells, yet squamous cell carcinomas constitute for most of the anal cancer cases.

Anal Cancer Symptoms:

• Bleeding from the rectum while passing feces.
• Pain and discomfort experienced in the anal region.
• Lumpy formations in the area around the anus that often gets misjudged for piles or hemorrhoids.
• The anus emitting at times either mucus-like or jelly-like discharge.
• Itchiness in the anal region.
• Variations in the movements of the bowels that could comprise of diarrhea, being constipated or loose stools.
• Incapacity to control bowel movements known as fecal incontinence.
• Feeling bloated or distended.
• Women might feel a sharp pain in the lower back due the pressure being exerted by the tumor on the vagina.
• Dryness felt in the vagina.

Anal Cancer Causes:

The true reasons behind the occurrence of anal cancer is still quite blurred, though the below stated factors could possibly raise the risks.

• Presence of HPV or Human Papilloma Virus – Some HPV forms have been strongly associated with anal cancer. Nearly, eighty percent of anal cancer cases arise due to HPV infection.
• Sexual Promiscuousness – has additionally been associated with HPV. The greater the shifting among sexual partners, the higher is the risk factor of contracting HPV that has strongly been related to anal cancer.
• Amenable anal intercourse – Both the sexes that opted for anal intercourse had an increased likelihood of developing anal cancer. A study has revealed that those HIV-infected men that had sexual contacts with the same sex were close to ninety times more prone to developing anal cancer as compared to the general populace.
• Other cancerous forms – Those women that had a past of vaginal or cervical cancer and men with a history of penile cancer are at a greater likelihood of contracting anal cancer. This has also been related to HPV infection.
• Aging – Aging is known to be directly proportional to development of anal cancer that seems to rise as age increases.
• A diminished immune system – Those with lowered immunity like HIV or AIDS infected persons, those having undergone transplants or are on the course of immunosuppressant medicines are noted to be at increased risk of developing anal cancer.
• Smoking – Those who smoke are more prone to contracting anal cancer than non-smokers. Factually, smoking has been noted to be the harbinger of a host of cancerous forms.
• Non-malignant anal abrasions – Inflammation arising from benign anal lacerations caused due to either irritable bowel disease or IBD, hemorrhoid, fistulae or cicatrices are known to raise the chances of developing anal cancers.
