Experts are urging that millions more Americans undergo screenings for colon cancer much earlier than current guidelines suggest, in order to catch this deadly disease before it spreads.
Dr. Michael Raphael, who specializes in treating young cancer patients, expressed to DailyMail.com that age limits for colon cancer screenings should be removed, especially as an increasing number of individuals in their 20s, 30s, and early 40s are receiving this diagnosis.
Colon cancer is rapidly becoming one of the most diagnosed cancers among young adults, particularly those aged 20 to 29, with an average annual increase of 2.4 percent in cases.
Often, younger patients are overlooked, causing their cancer to go undetected until it has advanced, which makes treatment more difficult.
The current guidelines in the U.S. recommend that everyone should have a colonoscopy starting at age 45. However, some physicians believe that anyone eager for a screening should be allowed to get one, independent of their age.
Dr. Raphael stated, “I strongly, strongly, strongly believe this screening age should be lowered to permit any patient, regardless of age, to be screened for colon cancer.”
Jessica Paulus, a former Harvard researcher who is now focused on colon cancer rates among younger populations, supports relaxing guidelines to enable earlier screenings for high-risk individuals.
This particularly applies to younger adults with multiple risk factors, including a family history of colon cancer, obesity, or those belonging to minority ethnic groups—demographics that tend to be diagnosed at later, often more advanced stages.
As a result, more than 44 million adults under 45 could potentially qualify for screening if these recommendations are implemented.
The U.S. Preventive Services Task Force (USPSTF), which establishes screening guidelines, had already lowered the recommended screening age from 50 to 45 in May 2021, citing a “moderate” benefit for patients.
Research indicates that around 34.5 percent of individuals aged 45 to 49 were screened for colon cancer in 2022, up from 19.7 percent the previous year.
Compared to other Western countries, the U.S. has a lower screening age; Canada sets its age at 50 while England lowered it from 60 to 50 in 2021.
Doctors maintain that those under 45 who exhibit symptoms or express concern about colon cancer could still access screenings through their health insurance, which might consider these tests as diagnostic rather than preventive.
The cost for a colonoscopy without insurance ranges from $1,250 to $4,800, though this varies widely by state.
Dr. Raphael noted that he and his wife each chose to be screened at 35, having no family history. He advised anyone concerned to do the same.
He added, “Although I’m from Canada and the U.S. has already set lower guidelines, I believe they should go further.”
During a talk at the American Society of Clinical Oncology’s annual conference in Chicago, he highlighted the alarming rise in colon cancer cases in the U.S.
Paulus remarked, “An algorithm used in lung cancer screenings could help identify who needs screening for colon cancer based on risk factors.”
She mentioned that factors like obesity might be included in risk assessments but suggested a multifactorial approach, considering family history and ethnicity, even though that could spark controversy.
Another doctor, Dr. Aparna Parikh, also advocates for a lowered age for screenings, stating, “As an oncologist who mainly treats younger patients, my bias is to advocate for earlier screening.”
Colon cancer screening typically involves a colonoscopy, where a flexible tube is inserted into the colon. Patients must fast for at least 24 hours before the procedure.
Alternative options consist of stool-based tests, looking for traces of blood or irregular shapes, or blood tests that detect DNA changes potentially signaling cancer.
Paulus shared findings from her team’s study, showing that half of the colon cancer patients diagnosed before 50 were actually under 45.
The research assessed over 104,000 colon cancer patients diagnosed between 2000 and 2024, including nearly 15,000 under 50.
They also found that those diagnosed with colon cancer at a younger age were more likely to be obese compared to older patients and typically belonged to urban areas or diverse ethnic backgrounds.
Some experts continue to argue against lowering the screening age. Dr. Pamela Kunz, who heads the Center for Gastrointestinal Cancers at Yale, stated, “Right now, the best data suggests that beginning screenings at age 45 offers the most benefit.”
She acknowledged that many factors contributing to the disease remain unknown, including genetics, environment, and diet.
Colon cancer rates are increasing among Americans under 50—a trend that’s puzzled researchers. Adults born in the 1980s now face double the risk of developing the disease compared to their parents, while rates have dropped 30 percent among those over 50 in the past 30 years.
Data from the CDC reveals an 85 percent spike in colon cancer rates among adults aged 25 to 29 over the last two decades.
