Stick out your tongue to check for this symptom. If your tongue appears to have white patches, you might be able to catch mouth cancer early. People who smoke or chew tobacco most often have leukoplakia. If the leukoplakia is caught early, cancer can be stopped before it starts. If you see a white patch on your cheeks or tongue, go directly to the doctor.
Bleeding is never a good symptom to have. If you bleed from the nipple, you might have breast cancer. If you are bleeding abnormally from the vaginal area, you might have cervical cancer or endometrial cancer. Coughing up blood indicates a lung problem. Blood in the stool could be a cancer indicator as well.
