Dr. David Samadi Weighs In: “Doctors Misuse Scans In Prostate Cancer: Study”
Too many men with low or medium-risk prostate cancer get CTs and bone scans that aren't recommended for them, suggests a new study. The scans are intended to tell doctors if cancer has spread beyond the prostate in men with high-risk cancer. Doing them in other cases is a concern because CTs expose patients to small amounts of radiation – which itself is linked to future cancer risks – and the scans cost the healthcare system extra money, but have little potential benefit. "In high-risk patients, those are the ones that have a high risk of positive lymph nodes or (cancer that has) spread to the bone," said Dr. David Samadi, a prostate cancer surgeon at The Mount Sinai Medical Center. "Otherwise for low-risk disease, the likelihood of finding a positive bone scan or CT scan is low," Dr. Samadi said.
