Cancer diagnosis is the process of finding out whether a person has cancer, its type, and its stage. Early diagnosis is very important because it increases the chances of successful treatment. Doctors begin with a physical examination to check for unusual lumps or changes. They also review the patient’s medical history to understand symptoms and risk factors.
A biopsy is one of the most accurate ways to diagnose cancer. In this test, a small sample of tissue is removed and examined under a microscope to check for cancer cells.
