An important consideration to factor into your treatment decisions is that success is not guaranteed. As many as half of the apparently localized cancers turn out, at surgery, to have already spread. And up to one-fourth, despite apparently successful surgery, will produce a recurrence over the next several years. Thus, while aggressive treatment will be unnecessary for some men, it will prove inadequate for others.
In coming to a decision, you may find it helpful to thoroughly discuss your treatment options, including benefits and side effects, with your wife/partner/family member. You may also consider contacting your local prostate cancer support group after consulting with your primary care physician and one or more specialists. Getting a second opinion and different perspectives can be very helpful.
Your decision does not need to be rushed. Take time to explore all your options. You may prefer a teaching hospital or a cancer center for treatment, and a surgeon or radiation oncologist who has extensive experience in the newest, least traumatizing techniques. You may want to take part in a clinical trial evaluating new approaches. You will also want to keep abreast of new developments. Ultimately, the decision rests with each individual. Each man has his own priorities and knows best which choices feel most comfortable for him.
