A new study has stated that for treating early-stage prostate cancer, men who have undergone surgery, may not need yearly PSA tests to screen for a cancer recurrence.

Researchers added that less frequent PSA screening among men who are at a low risk of cancer recurrence can opt for less-frequent PSA screening. This test can be conducted once in two years or may be even less frequent when it comes to a longer term.

The long-tern follow-up care can be changed substantially if this idea were widely applied for men treated for prostate cancer.

Radical prostatectomy is undergone by about 90,000 men. It is the surgical removal of the prostate.

According to Dr Mathew K Tollefson, a urologist at the Mayo Clinic in Rochester, Minnesota, and the lead researcher on the new study, in the US each year many men undergo this and 50 to 60 per cent of them are considered low risk for cancer recurrence.

Cancer can be detected in early stages through PSA blood tests and in men who have been treated for the disease it can also detect the early signs of a recurrence.

Presently men who undergo the surgery get their PSA test every few months.
