What Are the 7 Warning Signs of Cancer?
The American Cancer Society has historically used the mnemonic CAUTION to summarize seven key warning signs: Change in bowel or bladder habits; A sore that does not heal; Unusual bleeding or discharge; Thickening or lump in the breast or elsewhere; Indigestion or difficulty swallowing; an obvious change in a wart or mole; and a nagging cough or hoarseness. Recognizing early signs of cancer does not mean diagnosing yourself — it means knowing when to seek professional evaluation. Many of these symptoms have benign causes, but persistent or unexplained changes deserve a conversation with your doctor.
