How Does a Virus Cause Cancer?
Some viruses may alter the genetic makeup of cells and cause them to become cancerous (malignant). The risk that an oncogenic viral infection will eventually lead to cancer is higher in patients who have HIV/AIDS because a weakened immune system is less able to suppress tumor growth. Patients who have an AIDS-related cancer should find a cancer specialist (oncologist) who is also expert in the care and treatment of people with HIV/AIDS.
