Is it generally the case that a biopsy during a colonoscopy is not a good sign?

Generally, taking a biopsy during a colonoscopy does not necessarily indicate a serious condition. This is a routine clinical method to determine the nature of lesions, and there is no need for excessive anxiety. Detailed explanations are as follows:

During a colonoscopy, if abnormal mucosa is observed, such as polyps, ulcers, erosion, or rough mucosa, doctors usually take a small tissue sample for pathological examination to determine the nature of the lesion, such as inflammation, benign polyps, precancerous lesions, or malignant tumors. In most cases, these lesions are benign. For example, inflammatory polyps and hyperplastic polyps account for a high proportion among intestinal polyps. After pathological confirmation, these benign lesions can be effectively managed through endoscopic removal or medication. Even adenomatous polyps can be effectively prevented from progressing to cancer when detected and treated early. Only a minority of biopsy results indicate malignant lesions, but an accurate diagnosis at this stage helps in formulating a treatment plan promptly and improving prognosis.

Having a pathology examination during a colonoscopy does not always mean there is a severe problem; rather, it serves primarily as a diagnostic tool to clarify the condition of the intestine and guide subsequent treatment and management. Patients should maintain a positive attitude during the examination and cooperate with the doctor's diagnostic and therapeutic recommendations.
