Often a dot size of a red ink spot is the sole early sign of bowel cancer. Frequently, general practitioners tend to dismiss this symptom for piles telling their patients to not be worried about it.

Bowel Cancer Screening can help spot the disease early on. However, regrettably in countries like England, bowel cancer screening is offered only when one turns sixty years old and above. But, Scotland and other countries in the European Union this screening is obtainable from fifty years of age.

More than a hundred individuals are identified with bowel cancer on a daily basis in Britain. The death rates are soaring with sixteen thousand fatalities annually.

Bowel cancer when diagnosed in its early staging raises survival chances by ninety percent. The disease can be cured when spotted in its preliminary staging, however if not then there is solely 1-in-10 odds of the person being able be survive past 5 years.

With greater number of bowel cancer cases being diagnosed in the over-sixty age bracket of people, hence the last 2years has seen prompt roll out of screening programmes for those in the ages of sixty to sixty-nine years by the NHS in England. Eligible candidates are forwarded testing kits for use in their homes. The test checks for blood traces in stool sample and then sent back for evaluation purposes. In case there is an irregular test outcome then referral of that individual is done for examination.

Another issue is that solely fifty-two percent of those people entitled to get screened are actually taking it up. Often lesser knowledge and greater embarrassment about their bodies are the common reasons. When such people do visit their General Practitioner, mostly they get wrongly diagnosed with Irritable Bowel Syndrome (IBS) or piles. In case there is no improvement in a month’s time, especially with the blood loss and weight reduction, such people must ideally undergo endoscopy procedure – a pliable tubular device introduced for examining colon anomalies.

The most prevalent signs of bowel cancer are bleeding from the rear passage, blackish-appearing faeces and a variation in bowel motions.  Other symptoms comprise of weight loss, pain in abdomen and exhaustion.

A representative from the NHS Cancer Screening Programme states that the 60-69 year age bracket has been decided upon as it is a high-risk group having nearly eighty percent of bowel cancer cases being detected among sixty years and above individuals. A verdict on extension of age bracket for including fifty to fifty-nine year old people would be taken by concluding part of 2010.

Michael J. Thun, M.D., M.S., the senior author of the study, the vice president of emeritus, epidemiology and surveillance research at the American Cancer Society stated that colorectal cancer needs to be included in the long listing of cancers that arise as an outcome of cigarette smoking.

The findings have been printed in the December edition of ‘Cancer Epidemiology, Biomarkers & Prevention- a medical journal of the American Association For Cancer Research as part of a singular spotlight on tobacco.

Thun and his associates analysed the relationship in between long-standing smoking and colorectal cancer following amendment for numerous other factors which are usually linked with risk inclusive of screening. Between the time periods of 1992-2005, the researchers carried out a follow up of nearly 1,85,000 candidates in the ages of 50-74 years; entrants illustrated their behavioural patterns and medical conditions.

According to Thun, those candidates that engaged in smoking for four or more decades or that didn’t cease prior to turning forty had a 30-50% heightened risk of getting colon or rectal cancer during the time of follow-up, even in the study that amended thirteen other probable risk factors. Subsequent to thirteen years of follow-up, the researchers found 1,962 invasive colorectal cancer cases.

While past large-scaled studies carried out on long-standing smokers revealed analogous outcomes, Thun mentioned that this study is the foremost to control in case of screening and all of the doubted risk factors in case of colorectal cancer like consuming alcohol, sedentary lifestyles and consuming red or processed meats.

Thun concluded that such findings chip in to the proof lately reassessed by the International Agency for Research on Cancer (IARC) in October of the present year. After this IARC has advanced the proof that smoking leads to colorectal cancer from ‘limited’ to ‘ample’.

This re-categorization by IARC has brought the number of cancer organ locations causally linked to cigarette smoking to seventeen.

The rising occurrences of thyroid cancer have been credited to the highly sensitised screening procedures, however lately proofs suggest that this might not be the singular reason. Varied environmental features, like those linked to volcanoes, have not yet been expelled as risk factors.

In order to research this aspect, Gabriella Pellegriti, M.D., Ph.D., from the endocrinology branch, University of Catania Medical School, Garibaldi-Nesima Hospital located in Italy and associates gathered numbers of lately detected thyroid cancer cases in those residing in Sicily from January 1, 2002 till December 31, 2004 for comparing the rate of cancer occurrences in those inhabitants existing in the volcanic region of Mt. Etna of Catania in comparison to those residing in the rest of Sicily.

The researchers detected that inhabitants from the Catania province were observed to have more than 2 times increased frequency of papillary thyroid cancer, though not follicular or medullary thyroid cancers, than those residing in other parts of the island. Additionally, papillary tumors in patients from Catania had the more recurrently carrying BRAF V600 gene mutation that has been linked with a more belligerent form of thyroid cancer.

The author pointed out to the crucial aspect that a volcanic setting wherein there was production of lethal compounds that lie as hanging particulate material, gases and constituents could contaminate the water – and could raise the occurrence of thyroid cancer cases, though the means through which it had a bearing on the risk is still unclear.

The authors have penned down the crucial aspect that the conspicuous rise in papillary thyroid cancer occurrence that is linked to the Etna volcanic setting has lead them to imply that inhabitants of other volcanic regions could analogously be at a heightened risk of developing thyroid cancer, and probably, of others kinds of cancers too.

The authors further mentioned that in spite of definite risk factors for thyroid cancer in this volcanic location are still fuzzy; recognition of these factors could assist in gaining a better insight into the reasons of the rising cases of thyroid cancer in Europe and North America and possibly aid in developing deterrence methods.
