About Newsweek’s America’s Best Prostate Cancer Surgeons Honors
Prostate cancer is a major health concern. One in eight men will be diagnosed with prostate cancer at some point in their lives. Other than skin cancer, it is the most common form of cancer in men—the American Cancer Society estimates there will be nearly 300,000 new cases of prostate cancer this year in the U.S.—and it is the second-deadliest behind lung cancer. The American Cancer Society, though, does report some good news: From 1993 to 2013, prostate cancer’s death rate was cut in half, likely due to earlier detection and treatment advances.
To spotlight the country’s top prostate cancer specialists, Newsweek is partnering with Statista for the first annual ranking of America’s Best Prostate Cancer Oncologists & Surgeons. The ranking recognizes the top 150 individuals in each of the two categories.
The ranking is compiled from four sources: physician performance information based on Medicare data, an online survey of thousands of medical experts conducted in March and April, a quality-of-care rating from each specialist’s peers, and consideration of their certifications from the American Board of Urology, Radiology, and Internal Medicine.
For men dealing with prostate cancer, the doctors recognized here represent the best individuals to partner with in pursuit of a healthy future.
