Renin-angiotensin system, or RAS, is a physiological mechanism essential to human body function. The SARS-CoV-2 virus causes overactivation and malfunction of this system.
Severe SARS-CoV-2 infection is associated with a 1.31 higher risk of being diagnosed with cancer following hospital discharge, particularly renal, hematological, colon, and lung cancers, suggesting a potential link between the infection and undiagnosed cancer.
