Cancer may lurk behind major internal bleeding in cardiovascular disease patients

Patients with cardiovascular disease who develop major internal bleeding are much more likely to be diagnosed with cancer, a large international clinical trial has found. Patients with gastrointestinal (GI) bleeding are 18 times more likely to be diagnosed with GI tract cancer, and those who major genitourinary (GU) tract bleeding are 80-fold more likely to be diagnosed with GU cancer, than patients without internal GI or GU bleeding, respectively.
