Are colon adenomas serious?

Colitis is a very common anorectal disorder encountered in daily life—especially among middle-aged and elderly individuals. However, many patients only become vigilant after symptoms have persisted for a prolonged period, often delaying optimal treatment. Therefore, enhancing public awareness of colitis is essential. But how serious is a colonic adenoma?

How Serious Is a Colonic Adenoma?

A colonic adenoma is a serious condition. Although it is relatively common and has a high incidence rate, both men and women are at risk. A colonic adenoma is a type of colonic polyp. If left untreated, it carries a potential risk of malignant transformation (i.e., progression to cancer). Thus, colonic adenomas warrant prompt attention. Once diagnosed via colonoscopy, adenomas can typically be removed endoscopically during the same procedure, followed by histopathological examination. However, if the adenoma is large or technically difficult to resect via colonoscopy, laparoscopic or open surgical intervention may be required.

Although colonic adenomas are benign lesions, they possess malignant potential. Should malignant transformation occur, the condition becomes significantly more serious. Based on histopathological classification, colonic adenomas are categorized into three main types: tubular adenoma, villous adenoma, and tubulovillous adenoma. The majority of colorectal cancers arise from pre-existing colonic adenomas. Among these subtypes, tubular adenomas carry the lowest risk of malignancy; villous adenomas exhibit the highest risk; and tubulovillous adenomas fall somewhere in between.

Patients are advised to adopt a balanced diet—avoiding spicy and irritating foods—and to eat smaller, more frequent meals consisting primarily of easily digestible, liquid-based foods to allow the bowel adequate rest. We hope this information proves helpful.
