Diagnosis based on age 84 and PSA rise to 40
A friend was sent to a urologist due to a rise in PSA to 40 and age of 84. Urologist said he had prostate cancer. This was not based on a biopsy or other tests. I think the approach was considered "watchful waiting." I know there are treatments and that age is probably a major factor. I think he should request a biopsy to verify this. Comments and advice please?
