2. Change in a wart or mole. Changes in warts or moles may be indicative of melanoma or squamous carcinoma. Skin cancers may appear as dry; scaly patches, as pimples that never go away, or as inflamed or ulcerated areas. Warts or moles that grow or bleed should be checked, as should sores in the mouth that persist

3. Skin sore or a persistent sore throat that does not heal.  Sores that do not heal may also be indicative of melanoma. A persistent sore throat, hoarseness, lump in the throat, or difficulty swallowing, may indicate cancer of the pharynx, larynx, or esophagus.

4. Change in bowel or bladder habits. Continuing urinary difficulties, constipation, chronic diarrhea, abdominal pains, rectal or urinary bleeding, or dark tar-like stools should not be ignored; they should be regarded as signals to seek professional help.

5. Persistent cough or coughing blood. Coughs that become chronic, especially in smokers, should be checked. If there is a cancer in the air passages into the lungs, they may be partially obstructed or irritated or even bleed.

6. Constant indigestion or trouble swallowing. Difficulties in swallowing, continued indigestion, nausea, heartburn, bloating, loss of appetite, and bowel changes all may be symptoms of colon cancer or cancer of the stomach or esophagus. Unexplained weight loss is also an indicator.

7. Unusual bleeding or vaginal discharge. The early stages of uterine endometrial cancer and later stages of cervical vaginal cancer exhibit signs of unusual bleeding or vaginal discharge. Prompt attention to these symptoms means a better chance of catching cancer at its most treatable stage.

8. Chronic fatigue.  General feelings of chronic fatigue will often accompany any type of cancer that is rapidly progressing.
