The time period where the patient is not on the hormone treatment, the treatment side effects disappear and overall , very importantly, lead to a longer period of time before the tumour re-grows and becomes hormone treatment unresponsive . This study will test a modified androgen replacement phase in an intermittent therapy animal model, which involves using 5a-reductase inhibitor drugs, which block the conversion of testosterone to dihydrotestosterone. These drugs have very few side effects and their use may further prolong the time before the tumour no longer responds to hormonal treatment . Dr. Neil Fleshner , Toronto-Sunnybrook Regional Cancer Centre, for a study into how our environment may play a critical role in the development of Prostate Cancer. Oxidative stress is a process by which environmental factors such as dietary fat, smoking and lack of exercise can cause genetic damage to human cells.
Genetic damage is a distinguishing feature of cancer cells.
This study will assess the role of oxidative damage to prostate tissue in the development and progression of Prostate Cancer. It will thus provide an insight into the role of lifestyle related factors in the development of Prostate Cancer. It may also provide a indicator by which researchers can assess the efficacy of nutrition intervention studies. If done before symptoms occur, the simple blood test , in combination with a digital rectal examination, can signal early, potentially curable Prostate Cancer and give patients more options for treatment of the disease . The Newmarket US TOO Cancer Support Group , for the development of a series of videos on Prostate Cancer.
