LONDON, England (Reuters) -- Scientists have found a new way to identify a particularly deadly form of prostate cancer in a breakthrough that could save tens of thousands of men from undergoing unnecessary surgery each year.
In contrast to many cancers, only certain prostate tumors require treatment. Many are slow-growing and pose little threat to health. But separating the "tigers" from the "pussycats" -- as oncologists dub them -- is tricky.
Now that is set to change with new research showing how a genetic variation within tumour cells can signal if a patient has a potentially fatal form of the disease.
"This will provide an extra degree of certainty as to whether a cancer is going to be aggressive or indolent, and that's really what we want to know," Colin Cooper, professor of molecular biology at Britain's Institute of Cancer Research, told Reuters
