"Previous studies have indicated significant variation in prostate cancer rates, due to factors including detection practices, availability of treatment, and genetic factors," said study author MaryBeth Freeman. She's a senior associate scientist for surveillance research at the American Cancer Society.
"By comparing rates from different countries, we can assess differences in detection practices and improvements in treatment," Freeman said in a news release from the American Association for Cancer Research (AACR).
Researchers examined long-term and short-term data from 44 countries with incidence data and 71 countries with prostate cancer death data.
