Sarah DeBord was 24 when she first noticed blood in her stool. She saw a gastroenterologist who did a procedure called a flexible sigmoidoscopy to examine her lower colon and rectum, then gave her a diagnosis of hemorrhoids. DeBord recalled the doctor saying.
When researchers reported earlier this year that colorectal cancer rates were rising in adults as young as their 20s and 30s, some scientists were skeptical. The spike in figures, they suggested, might not reflect a real increase in disease incidence but earlier detection, which can be a good thing. They are dying of colorectal cancer at slightly higher rates than in previous decades, and no one really knows why.
R achel Winegar, a mother of three from Colorado, has had trouble with her digestive system for as long as she can remember. So when she neared 30 and her problems intensified, colorectal cancer did not cross her mind. After she finally went to a doctor, Winegar was scheduled for a colonoscopy. It was stage 4 cancer.
Nobody in their 20s, 30s or 40s gets colorectal cancer, right? The truth is that colorectal cancer is on the rise in young adults and has been for years. During a recent week, all of the seven patients the practice saw who were diagnosed with rectal cancer were young; the oldest was
Most cancers in the colon develop from polyps, which are growths that form within the inner lining of the colon. While most polyps do not actually turn into cancer, the ones that are most likely to are called adenomatous polyps or adenomas. Large polyps greater than one centimeterpolyps that contain abnormal cells called dysplastic polypsand having two or more polyps within the colon also increases the likelihood for colon cancer.
Colorectal cancer can start in either the colon or rectum. While doctors are seeing more young people get colon cancer, they are seeing even more get rectal cancer, says colorectal surgeon Mukta Krane, M. Suspected causes include poor diet, obesity and changes in gut bacteria also known as the gut microbiome.
A polyp is an abnormal growth on the inner surface of the large intestine, which includes the colon and the rectum. It's possible to have multiple polyps that are flat or raised as if they are on a stalk. Polyps are one of the most common colorectal conditions, occurring in 15 - 20 percent of the adult population.
The colorectal adenoma is the precursor lesion in virtually all colorectal cancers. Occurrence of colorectal adenomas has been studied in older adults but analysis in younger adults is lacking. The prevalence by age, sex, race, and location, and the number of colorectal adenomas detected was investigated using epidemiologic necropsy in persons aged 20—89 autopsied from to at the Johns Hopkins Hospital. Results were standardized to the general population.
