News Finding: As a whole, men diagnosed with prostate cancer were at a lower risk of developing a second cancer.
Paper Finding: Second primary malignancies required a minimum 2-month latency period after the primary diagnosis to exclude synchronous primary cancers.
News Context: "Overall the incidence of these cancers is low. As a whole, men diagnosed with prostate cancer were at a lower risk of developing a second cancer. But when researchers looked at patients who received external beam radiation therapy, they found these patients were estimated to be 70 percent more likely to be diagnosed with a rectal cancer and 40 percent more likely for bladder cancer than the general public.
Paper Context: The SEER13 data cover 13.4% of the total US population and 11.%, and 11.3% of the total white and black US population, respectively. Second primary malignancies required a minimum 2-month latency period after the primary diagnosis to exclude synchronous primary cancers. Of these, 44,310 men (10%) developed a second primary malignancy during the observation period (Table 1) .
