Prostate Cancer that has metastasized to the remote locations mostly reaches the bones, but would continue to be known as prostate and not bone cancer. A Radionuclide bone scan comes into the picture to assist in showing if the cancer has inflicted the bones. For performing a radionuclide bone scan a miniscule quantity of radioactive matter is administered as an intravenous shot after which the material would settle in the bone tissue that has faced damage all through the skeletal system in the span of a few hours. The person is then requested to lay flat on a table for nearly thirty minutes during which time a specialised camera identifies the radioactive substance and produces an image of the skeletal structure. Regions where the bone tissue have been damaged due to the cancer presence are  [...]

Researchers from the UC San Diego School of Medicine have identified a system that could be helpful in explicating the way in which chromosomal translocations – the apparently arbitrary shuffle of big masses of DNA that often cause cancer – are not that accidental after all. The scientists have evolved a model of these chromosomal muddle up in prostate cancer that suggest that androgen (male sex hormone) receptor unpredictably dons a vital role in impelling particular translocations in the progress of cancer. An improved understanding of the source and behaviours of these translocations could finally lead to means of both predicting and possibly obstructing their creation and eventually the cancer developing.

The New Mayo Clinic research examines the relationship between PSA or prostate specific antigen and size of the prostate. The research discovered that the regular yearly prostate cancer evaluation is not essentially a forecaster for the progress of prostate cancer. Yet, the study proposes that in case the PSA levels are swiftly increasing, it is logical to undergo a prostate biopsy for ascertaining the presence of prostate cancer. The presentation of these findings by Mayo Clinic was put forth at the North Central Section of the American Urological Association in Scottsdale, Ariz. The findings were derived from a vast group study of men residing in Olmsted County, Minn. The researchers arbitrarily picked 616 men in the age groups of 40-79 years that didn’t suffer from prostate disease. The  [...]

Prostate Cancer Treatment that has metastasized (beyond the prostate) Conformal Radiotherapy (Computer-controlled Radical Radiotherapy) A form of external radiotherapy wherein metal obstructers are introduced in the shaft of the X-rays that makes them more pliable and aid in matching more accurately to the contours of the prostate. Usually employed radiotherapy employs an additional ‘strewn’ beam, hence has lesser precision and could affect adjacently placed normal tissues. Pros The treatment has greater accuracy as compared to normal radiotherapy translating to adjoining healthy tissues being lesser affected. Also this procedure has lesser side effects. IMRT or Intensity-modulated radiotherapy is the latest kind of conformal radiotherapy that could distribute varying dosages of radiation.  [...]

A study that was lately presented during the 51st Annual Meeting of the American Society for Radiation Oncology in Chicago revealed that Proton beam therapy could be effectually administered to those men having prostate cancer and was observed to have negligible urinary and rectal side effects. Researchers aimed at ascertaining whether administering elevated radiation dosages using proton beam therapy could lead to early detrimental side effects to the urinary function within the GU or genitourinary system and the rectal functioning within the GI or gastrointestinal system. Proton therapy is quickly garnering immense popularity as a potent prostate cancer treatment, but it is fuzzy as to whether the long-standing results of proton therapy would surpass those attained by other treatment methods.  [...]

A latest research has revealed that those men having desk jobs were more prone to developing prostate cancer. The study showed that those spending major part of their professional lives being seated were nearly thirty percent more prone to being detected with the ailment as compared to those having energetic and active jobs. Examination of forty-five thousand men in the age group of 45-79 years that had vastly physical jobs were twenty-eight percent less prone to developing the ailment as compared to those men spending majority of their professional lives doing desk jobs. However, the British Journal of Cancer reported that those men who remained seated for half of the entire time at work had a twenty percent lowered risk as compared to men that remained sedentary for the entire span of their  [...]

Getting screened for early symptoms of cancer would appear the most apt decision to take, considering the aspect of early detection. However research has revealed that screening do not always prolong life span and could actually lead to belligerent and needless follow-up testing or treatments that could potentially lead to incontinence and impotency among those men. Some of the doctors think that the test would be more harmful that useful for certain kinds of men. Factually, novel instructions lately released by the USPSTF (United States Preventive Services Task Force) suggest that men that are 75 years or above omit the test in case they have no reason to doubt that they are in the high risk bracket. In case of men less than 75 years, the USPSTF conclude that there is dearth of plausible proof  [...]

A potent, ultrasensitive test that cautions of the early reappearance of prostate cancer has now been developed by scientists from US and Australia. This would translate to recurrences being potentially spotted early on – that would help in saving ten thousand lives annually that perish due to the disease. The novel bio-barcode assay used by the team employs gold nanoparticles and DNA as intensification agents for detecting PSA or prostate specific antigens – a protein whose production increases with the growth and proliferation of cancer. This is known to be three hundred times more responsive as compared to other commercial assays. PSA levels among those who have undergone surgical removal of their prostate gland characteristically plummet to an extent that is unnoticed by the usual assays.  [...]
