PROSTATE CANCER – NEW TREATMENT BY RADIOTHERAPY
Research is continuing to try and improve technology and techniques to allow radiotherapy to the prostate gland to be more effective and to have fewer side effects. One way is to reduce the amount of radiation received by normal organs (bladder, bowel etc) and this has been improving over the last few years with better machines and techniques such as “conformal radiotherapy” and “IMRT”.
Work is also being carried out on combining brachytherapy with external therapy to allow some of the benefits of brachytherapy (fewer side effects, higher overall dose to the prostate cancer) to be used for men with more advanced prostate cancer without compromising the chance of cure.
NEW HORMONE THERAPY FOR PROSTATE CANCER
Some newer prostate cancer hormone treatments have fewer side effects than older hormone based drugs. Some are also felt to be more effective. All the time… Read More

While many illnesses and diseases are well understood, prostate cancer is one of the remaining cancerous conditions that is shrouded in misunderstanding. There are several main reasons for this, not the least of which is that men as a group, simply do not want to deal with this very common no cancerous condition.
For many men, prostate cancer affects the very core of how they define their own manhood. The prostate is a key component in the sexual performance and ability of men. Prostate cancer than strikes at the very heart of how many men view themselves. In any event here are a few of the most common questions concerning prostate cancer.
1. What really is prostate cancer?
Prostate cancer is any abnormal and malignant growth of cells in the tissues of the prostate gland and possibly all over and beyond the prostate.

Carcinogenesis is the creation of a cancer.
Cancer is, ultimately, a disease of genes. Typically, a series of several mutations is required before a cell becomes a cancer cell. We distinguish between oncogenes, which promote cancer when “switched on” by a mutation, and tumor suppressor genes, which prevent cancer unless “switched off” by a mutation. These mutations can have various causes: radiation or chemicals called carcinogens; some inherited predisposition is not uncommon; some viruses that can cause cancer have also been described. Usually, they carry in their genome some oncogene or tumor suppressor inactivating gene. In about 15% of all cancers, viruses seem to play a role. Finally, damage by free radicals, which are a natural by-product of oxygen metabolism, can cause mutations in the DNA.
For most of the cancers, it cannot be told which event was the initial cause. However, with molecular biology,… Read More
