  • prostate cancer by 10%;
  • lung cancer by 30%;
  • oncology of the throat and esophagus by 60%.

Finnish doctors have published data suggesting that taking acetylsalicylic acid doubles the mortality rate after cerebral hemorrhage (compared with those patients who did not use aspirin). Historical researchers have put forward the theory that the high mortality rate from the “Spanish flu” in 1918 is associated with the massive use of aspirin in large doses (10–30 g each).
