# Colorectal cancer screening: why get screened? March 31, 2025 3 minutes Personal Health Evidation is on a mission to help our members and their families stay healthy through colorectal cancer screening. ## What is colorectal cancer? [Colorectal cancer](https://www.cancer.org/cancer/types/colon-rectal-cancer/about/what-is-colorectal-cancer.html) is the term used to refer to cancer that starts in the colon or rectum — which make up the large intestine. Sometimes it’s referred to as colon cancer or rectal cancer, depending on where it starts. Most colorectal cancer starts with a growth, called a polyp, on the lining of the [colon](/content/blog/foods-good-for-colon-health/index.html) or rectum. Polyps are common, especially in older adults, and most are benign (non-cancerous). However, sometimes these polyps can become cancerous over time. Which is why regular screening is so important. It saves lives. ### Colorectal cancer facts - Colorectal cancer (CRC) is the **4th most common** type of cancer. But the good news is, if caught early, it’s highly treatable. - Certain individuals—including people of color and those with type 2 diabetes, a family history of CRC, inflammatory bowel disease, or hereditary conditions like Lynch syndrome—are considered **higher risk**. - While CRC is most common in older adults, **rates are rising in young adults**. - Colorectal cancer often has **no symptoms** in its early stages. - However, symptoms can include changes in bowel habits, persistent abdominal discomfort, rectal bleeding, weakness, and/or unexplained weight loss. If you experience these symptoms, contact your healthcare provider and let them know your concerns. ## Why get screened? - **It’s easy—and you have options**, including colonoscopies and at-home stool tests. - Screening can help **detect cancer early** and, in some cases, **prevent it**—colonoscopies can remove precancerous polyps before they become cancerous. - Many screening options are **low or no cost** for those undergoing routine screening. - **Peace of mind**—it’s normal to feel nervous about medical tests, but your future self will thank you. ## Who should get screened? - **If you’re 45 or older**, screening is recommended by the U.S. Preventive Services Task Force, the American Cancer Society, and the Colorectal Cancer Alliance for individuals at **average risk**. - If you have **certain risk factors**, like those listed below, work with your healthcare provider to determine the right time to start screening—it’s often much earlier than 45. ### Risk factors A risk factor is anything that increases your risk of developing cancer. Common [risk factors](https://www.cancer.org/cancer/types/colon-rectal-cancer/causes-risks-prevention/risk-factors.html) for colorectal cancer include: - Type 2 diabetes - Being overweight or obese - Dietary factors (like high-fat or heavy red meat diets) - Low vitamin D levels - Smoking - Alcohol use - Racial and ethnic background (Ashkenazi Jews, American Indian and Alaskan natives, and Black & African Americans are at higher risk) - History of inflammatory bowel disease - Family history of colon cancer > _“A goal without a plan is just a wish.” – Antoine de Saint-Exupéry_ ## What should I do now? If you're **45 or older (or turning 45 soon)** and have never been screened, now is the time to make a plan. Many people delay screening due to busy schedules—but prioritizing your health is worth it. Here’s what you can do next: 1. **Call your doctor** and ask about colorectal cancer screening. Set a calendar reminder, leave yourself a note, or ask a family member to help you follow through. 2. **Have questions?** The Colorectal Cancer Alliance offers a **free helpline** at (877) 422-2030, where you can speak with certified patient navigators. 3. **Learn more** about screening and prevention at the [Colorectal Cancer Alliance website](https://www.ccalliance.org/). 4. **Already up to date?** Check in with your family and encourage them to stay on top of their screenings too. ## Screening saves lives When found early, colorectal cancer is treatable and survival rates are high (over 90% when caught before stage 2). So catching it in the beginning stages is critical. But **screening can also prevent colorectal cancer from developing** at all. Precancerous polyps can be removed during a colonoscopy to prevent cancer from ever forming. If you’re 45 or older or have any of the risk factors mentioned above, make a plan to get screened — it could save your life. And don’t forget to talk to your loved ones too. Reminding your family and friends to get their screenings could save their lives as well.
