Abstract:
Annually, there are nearly 3000 new cases and 500 deaths from prostate cancer in Missouri. When treatment is appropriate and necessary, radiotherapy offers similar cure rates to prostatectomy, with fewer long-term sexual side effects and little effect on urinary continence. Radiotherapy is delivered with external beam or implanted radioactive sources (brachytherapy). In high-risk disease, combinations of external beam and brachytherapy offers improved biochemical control. Following prostatectomy, salvage radiotherapy should be initiated as soon as possible.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
