DEAR DOCTOR K: I have prostate disease and treatment hasn't worked. My doctor suggested I participate in a clinical trial. I'd like to know more before I give him an answer.
DEAR READER: When established treatments aren't effective, participation in a clinical trial can be a good option. Such trials give you access to promising treatments that might work better than one already on the market. On the other hand, clinical trials test treatments that are still under investigation. There may be unpleasant or serious side effects. Clinical trials are designed to minimize risks to participants, but they cannot completely eliminate them.
