Cancer can cause many different symptoms. These are some of them:

• A thickening or lump in the breast or any other part of the body
• A new mole or a change in an existing mole
• A sore that does not heal
• Hoarseness or a cough that does not go away
• Changes in bowel or bladder habits
• Discomfort after eating
• A hard time swallowing
• Weight gain or loss with no known reason
• Unusual bleeding or discharge
• Feeling weak or very tired

Most often, these symptoms are not due to cancer. They may also be caused by benign tumors or other problems. Only a doctor can tell for sure. Anyone with these symptoms or other changes in health should see a doctor to diagnose and treat problems as early as possible.

Usually, early cancer does not cause pain. If you have symptoms, do not wait to feel pain before seeing a doctor.
