Colorectal cancer (CRC) is the second leading cause of cancer death in the U.S.
Key Facts on Colorectal Cancer
* Screening Saves Lives: Screening, starting at age 45, can prevent CRC by finding and removing precancerous polyps before they turn into cancer.
* Rising in Young Adults: Rates of CRC are increasing by about 1% annually in people under 55, making it a major, often later-diagnosed, threat to younger generations.
* Symptoms Often Invisible: Early-stage colorectal cancer rarely causes symptoms. When they appear, they can include blood in stool, persistent stomach pain, or unexplained changes in bowel habits.
* High Survival Rates: When detected early (localized), the 5-year survival rate is over 90%.
* Risk Factors: Key factors include a sedentary lifestyle, unhealthy diet (high in red/processed meats), smoking, alcohol consumption, and obesity.
Anyone, regardless of age, with symptoms should consult a doctor. Those with a family history of colorectal cancer may need to begin screening before age 45.
