Each year, more than 50,000 people die from colorectal cancer in the United States, and it remains the third leading cause of cancer-related deaths. Colorectal cancer also remains one of the most preventable cancers. With proper screening, responsive medical care, and healthy lifestyle choices, colon cancer can be prevented or detected early when it is highly treatable.
Risk factors
You may be more at risk if you:
- Are aged 50 and older
- Have a family history or personal history of colorectal cancer
- Have had precancerous polyps
- Have any of the inflammatory bowel disorders
- If you smoke
- If you are obese
- If you do not get enough exercise
- Certain studies have also found potential links between colorectal cancer and alcohol use, diabetes, and exposure to radiation.
Screening recommendations
Most people should start being screened at age 50. Those with an increased risk may receive a screening earlier. There are a variety of tests that are used to screen for colorectal cancer, including:
- Tests that screen stool samples for blood
- Digital rectal exam
- Barium enema
- Colonoscopy
- Flexible sigmoidoscopy
According to the Centers for Disease Control and Prevention (CDC), approximately 60% of deaths from colorectal cancer could be avoided if everyone aged 50 or older were screened regularly.
Prevention tips
To prevent colorectal cancer or detect it early:
- See your doctor if you have any changes in your bowel movements, including bloody stools, cramping, change in size, shape or frequency.
- Eat a diet high in fiber rich fruits and vegetables along with healthy fats like coconut oil, avocados, and olive oil, to support your intestinal health.
- Avoid alcohol, refined carbohydrates and processed meats.
- Some new research indicates that vitamin D, calcium, and selenium may also help protect your colon. Discuss with your doctor your need for any extra vitamins or minerals.
Discuss concerns with your doctor to determine a screening schedule and options that provide the best choice for you.
