Rectal bleeding in young adults linked to 8.5 times higher risk of colorectal cancer

INTRO: Adults under 50 undergoing colonoscopy were found to have a dramatically higher risk of having colorectal cancer when the procedure was done for rectal bleeding. Researchers found that rectal bleeding increased the odds of a colorectal cancer diagnosis by 8.5 times, underscoring the need to take the symptom seriously even in the absence of a family history in a population who may not otherwise meet screening age criteria.
The research will be presented at the American College of Surgeons (ACS) Clinical Congress 2025 in Chicago, October 4-7.
The retrospective study analyzed 443 patients under 50 who underwent a colonoscopy at the University of Louisville Health System between 2021 and 2023. Of them, 195 (44%) were diagnosed with early-onset colorectal cancer, while 248 (56%) had normal results.
“Many of the early-onset colorectal cancers that I see have no family history,” said senior author Sandra Kavalukas, MD, FACS, a colorectal surgeon at the University of Louisville School of Medicine in Louisville, Kentucky. “This research lends support to the question of who does or doesn’t warrant a colonoscopy: if you have a person below the screening age with rectal bleeding, you should seriously consider a colonoscopy.” (MORE - details, no ads)
Drop in credit score after cancer diagnosis linked to increased mortality, study shows
https://www.eurekalert.org/news-releases/1100527
KEY POINTS: Among 42,451 patients, 8.5% developed financial toxicity (a credit score below 600) after their diagnosis; an additional 3% were already in that category.
Patients whose credit score fell by two tiers within 12 months of diagnosis faced a 29% higher risk of death. Over any six-month period after diagnosis, a one-tier drop increased mortality risk by 12%, and a two-tier drop raised it by 63%, compared with patients whose scores stayed stable.
An increase in credit score was not found to be a protective factor against mortality... (MORE - details, no ads)
