Colon cancer often develops quietly, but catching it early can make it easier to treat. That’s why preventive screenings are so important.

Due to the rise of colon cancer in people under 50, the recommended age to begin colon cancer screenings was recently lowered from 50 to 45. Starting at age 40 is recommended for those at higher risk due to personal or family history. Your Costco medical plan covers colonoscopies at any age at no cost.

Signs and symptoms of colon cancer

Talk to your primary care provider (PCP) if you notice any of these symptoms:

• Changes to your bowel habits
• Blood in your stool
• Ongoing belly pain or bloating
• Unexplained weight loss
• Extreme fatigue

Your PCP can help you schedule a colonoscopy and talk to you about what to expect. Some of the most serious health conditions don’t come with warning signs, which is exactly why screenings matter so much.

Know your screening schedule

Your PCP tracks your health over time and can recommend screenings for your age, gender, and health history.
