According to a new study, a rise in new technologies to treat prostate cancer has led many men to undergo costly treatments they probably did not need.
Researchers from the University of Michigan examined the records of nearly 56,000 men who had been diagnosed with prostate cancer.
All the men in the study had more severe health problems or the cancer was so small that they were unlikely to die of the cancer.
About 16,000 of the men opted to forego treatment, and just keep a close eye on their cancer.
However a growing number of men underwent either robotic surgery or targeted radiation, both of which are advanced technologies that have been introduced only in the past decade.
These treatments can come with side effects which can include incontinence and impotence.
