What are the seven warning signs of cancer?

The American Cancer Society lists the following seven warning signs of cancer:

1. A change in bowel habits. This includes diarrhea, constipation, or a change in the size or shape of stools.

2. A sore that does not heal. This includes sores on the skin, in the mouth, or on the genitals.

3. Unusual bleeding or discharge. This includes bleeding from the vagina between periods, bleeding after menopause, or bleeding from the rectum.

4. Thickening or lump in the breast or elsewhere. This includes a lump in the breast, underarm, or neck.

5. Indigestion or difficulty swallowing. This includes a feeling of fullness after eating, heartburn, or difficulty swallowing.

6. Obvious change in a wart or mole. This includes a change in size, shape, or color.

7. A persistent cough or hoarseness. This includes a cough that lasts for more than two weeks, or a change in voice.

It is important to note that these warning signs do not always indicate cancer. However, it is important to see a doctor if you experience any of these symptoms.
