Narrator: This is Science Today. Prostate cancer is the most commonly diagnosed cancer in men. One out of six American men is at lifetime risk of prostate cancer and if a close relative has the disease, the risk more than doubles. Dr. Peter Carroll, a prostate cancer specialist at the University of California, San Francisco Medical Center, says it's also one of the most treatable of cancers and has a range of options.

Carroll: Watchful waiting, surgery, radiation therapy or even newer forms of treatment.

Narrator: Carroll says for those who chose surgery, the majority of patients are candidates for refined techniques.

Carroll: Where we can spare the nerves around the prostate to ensure maintenance of normal sexual function and urinary control.

Narrator: At the UC San Francisco Prostate Cancer Center, investigators and physicians collaborate to discover the fundamental, biological processes underlying prostate cancer and work towards new ideas for prevention, diagnosis and treatment of the disease.

Carroll: You get quality care at the cutting edge of what research has to offer.
