While this approach may seem out of the question in most cases, withholding treatment is appropriate and justifiable incertain circumstances. The treatments might be more risky than the disease. In the absence of symptoms, and in the presence of other medical situations which are more threatening, observation is correct. Chemotherapy Chemotherapy is the use of medicines or drugs to stop the growth of cancers. The drugs are very powerful and work by killing cells that tend to grow quickly.
Cancers tend to grow quickly, but unfortunately, so do cells in bone marrow, gut and other areas.
Anemia, weakness, nausea, vomiting, diarrhea and other side-effects can occur. Unfortunately, chemotherapy rarely cures prostate cancer, but merely palliates or temporizes the cancer growth. Chemotherapy, therefore, is not used for localized prostate cancer. The prostate gland is uniquely male. Its very existence is due to the presence of male hormones, which the prostate, and most prostate cancers require to grow.
