Cancer research continues to make strides, but it’s still not completely clear what causes colon cancer. We do know most colon cancer begins as a growth called a polyp. And while not all polyps become cancerous, the only way to find out is by getting screened.

Between screenings, it’s important to keep an eye on your body and note any changes you experience. Here are signs that may indicate colon cancer:

1. A change in bowl habits or a narrowing of your stool diameter before age 50.

2. Rectal bleeding or blood in your stool.

3. Unusual or persistent abdominal discomfort, such as cramps, gas or pain.

4. Feeling like your bowel doesn’t empty completely after passing stool.

5. Unexplained weight loss, weakness or fatigue and vomiting.

If you notice any of these signs, make an appointment with your doctor. And remember, getting regular screenings is your best defense, as many people with colon cancer experience no symptoms at all during the early stages of the disease.

Talk to your doctor about the signs and symptoms of colon cancer and find out when you should begin screening.
