Colon cancer starts in the large intestine, also called the colon. It used to be seen mostly in older adults. Today, doctors are finding it more often in people under age 50. Because of this change, it is important for everyone to know the warning signs and their risk.

Some people have no symptoms at all, but some common symptoms include

• Blood in the stool
• Stomach pain that does not go away
• Changes in bowel habits (like diarrhea or constipation)
• Losing weight without trying

These symptoms can have many causes, but you should talk to a health care provider if they last more than a few weeks.

People at average risk should begin colon cancer screening at age 45. Screening can detect cancer early—when treatment is most effective—or find small growths before they turn into cancer. People with a family history of colon cancer or certain health conditions may need to start screening earlier. Your health care provider can help you understand your risk and give you guidance on lifestyle changes to help prevent the disease, like eating healthier meals, exercising regularly, limiting alcohol, and not smoking.

Patients with medical insurance can get colon cancer screening at no cost as part of their preventive care. For patients without insurance, Zufall Health offers help through the New Jersey Cancer Education and Early Detection Program (NJCEED). This program provides free cancer screenings for people in Morris County and Somerset County who meet certain income and insurance guidelines. If you do not qualify for NJCEED or live outside these counties, Zufall Health can still help you find affordable screening options.
