Colorectal cancer is becoming a growing health concern for younger Americans. Once considered a disease that primarily affected older adults, it is now the leading cause of cancer-related death in men under 50 and the second-leading cause in women under 50 in the United States, according to the latest research from the American Cancer Society (ACS). This dramatic shift has prompted doctors and public health experts to encourage earlier screening and greater awareness of symptoms.
A comprehensive study published by the American Cancer Society found that while death rates for several major cancers—including lung, breast, leukemia, and brain cancer—have continued to decline among people under age 50, colorectal cancer mortality has steadily increased over the past three decades. Researchers reported that colorectal cancer rose from the fifth-leading cause of cancer death among younger adults in the early 1990s to the leading cause by 2023.

Experts are still working to determine why colorectal cancer is becoming more common in younger adults. Researchers believe several factors may be contributing, including obesity, sedentary lifestyles, diets high in processed foods and red meat, changes in the gut microbiome, environmental exposures, and genetic risk factors. However, no single cause has been identified, and additional research is ongoing.
One of the greatest challenges is that younger adults often do not believe they are at risk. As a result, symptoms such as persistent abdominal pain, rectal bleeding, unexplained weight loss, fatigue, or changes in bowel habits may be dismissed or mistaken for less serious conditions like hemorrhoids or irritable bowel syndrome. This can delay diagnosis until the cancer has reached a more advanced stage, making treatment more difficult.
Recognizing these trends, the U.S. Preventive Services Task Force (USPSTF) and the American Cancer Society now recommend that adults at average risk begin routine colorectal cancer screening at age 45, rather than waiting until age 50. Individuals with a family history of colorectal cancer or certain inherited conditions may need to begin screening even earlier.
When Can a Delayed Diagnosis Become Medical Malpractice?
While not every delayed cancer diagnosis is the result of negligence, there are situations where a healthcare provider’s failure to meet the accepted standard of care may have serious legal consequences. Medical malpractice may occur if a doctor fails to investigate concerning symptoms, does not order appropriate diagnostic testing, misinterprets imaging or laboratory results, or fails to refer a patient to a specialist when warranted.
When colorectal cancer is diagnosed months or even years later than it reasonably should have been, the disease may progress from a highly treatable stage to one requiring aggressive surgery, chemotherapy, or other extensive treatment. In some cases, a delayed diagnosis can significantly reduce a patient’s chance of survival.
An experienced medical malpractice attorney can review medical records, consult qualified medical experts, and determine whether the delay in diagnosis may have violated the applicable standard of care. If negligence contributed to a worse outcome, patients and their families may be entitled to seek compensation for additional medical expenses, lost income, pain and suffering, and other damages.
Staying Vigilant Could Save Your Life
The continued rise in colorectal cancer among younger adults serves as an important reminder not to ignore persistent digestive symptoms, regardless of age. Early detection remains one of the most effective ways to improve survival, with localized colorectal cancer having a five-year relative survival rate of about 91%, according to the ACS.
If you or a loved one believes a delayed diagnosis of colorectal cancer resulted from a healthcare provider’s negligence, speaking with an experienced medical malpractice attorney can help you understand your legal rights.
