BRUNSWICK, Maine (NEWS CENTER) -- It's a cancer that affects one in six men in this country and sometimes the best option is to do nothing.
Michael Mahan was diagnosed with prostate cancer three years ago. Because Mahan's cancer was caught so early, doctors said he was a good candidate for active surveillance. It's a plan where the patient and the doctor closely monitor the disease for any changes.
Mahan chose not to do any medical treatment because surgery and radiation can can cause serious side effects, including urinary problems. Three years later Mahan's cancer hasn't spread.
'It's not like you ignore it. You are getting blood tests couple of times a year. You are getting an exam, I've had two biopsies. I will get another one in July, if that shows no change in the cancer I probably won't have another one in July, if that shows no change in the cancer I probably won't have another for five years,' said Mahan.
The 15-year survival rate for prostate cancer is 93 percent with or without medical treatment.
