Colon Cancer Awareness Q&A
- Can you explain what colon cancer is and why it’s such an important health issue?
Colon cancer, also known as colorectal cancer, begins in the colon or rectum. It often starts as a small, noncancerous polyp that can become cancerous over time.
- How common is colon cancer in the US and who is at most risk?
Each year over 154,000 new cases are diagnosis in the US, with nearly 53,000 deaths. It is the leading cause of cancer death in men and the second in women under 50, with mortality rates rising 1.1% annually
- What screening options are available?
Screening options include colonoscopy and at-home stool tests. A colonoscopy can detect and remove polyps before they turn into cancer.
- At what age should people start getting screened for colon cancer? Does family history change this?
Most adults should begin screening at age 45. Those with family history may need to start earlier. More than 1 in 3 adults over 45 are not screened as recommended. Risk factors include older age, inflammatory bowel disease, family history of colon cancer, low-fiber, high-fat diet, and lack of physical activity.
- How does early detection impact survival rates?
When caught early, colon cancer is highly treatable. The overall 5-year survival rate is about 65%, and survival is much higher with early detection.
- What is the main thing you want patients to know about colon cancer and screening?
Colon cancer is preventable, treatable, and beatable – especially when caught early.
