biopsy techniques

A biopsy is a medical procedure used to remove a small sample of tissue from the body for examination. There are several techniques, including: 1. **Needle Biopsy**: A thin needle is inserted into the tissue to extract samples, often guided by imaging. 2. **Endoscopic Biopsy**: A thin, flexible tube with a camera is inserted into body passages to collect tissue. 3. **Surgical Biopsy**: A larger section of tissue is removed through a surgical procedure. The collected tissue is then analyzed by a pathologist to diagnose diseases, including cancers. Biopsies are crucial for accurate diagnosis and treatment planning.
