My son was treated for prostate cancer 8 years ago. He is going from doctor to doctor looking for where the cancer may have gone to, becoming more and more anxious, from test to test, doctor to doctor. He saw a psychologist a few days ago who suggested he exercise, that he was a class A personality and depressed and scheduled an appointment two weeks from now. I am afraid he is going to be unable to function at all. What can I suggest he do? He is looking for reassurance and as soon as a test is fine, the spiral begins again and it is heightening to the point he wants to see a doctor practically daily.
