polyyppi

Polyyppi is a medical term referring to an abnormal growth of tissue projecting from the lining of an organ into a hollow space. Polyps are often benign, meaning they are not cancerous, but some types can develop into cancer over time. They can occur in various parts of the body, including the colon, nose, uterus, and stomach.

The exact cause of polyp formation is not always clear and can vary depending on the location and type of polyp. Factors such as inflammation, genetics, and environmental influences are thought to play a role. In some cases, polyps may not cause any symptoms and are discovered incidentally during medical examinations. When symptoms do occur, they can include bleeding, changes in bowel habits, pain, or discharge, depending on the polyp's location.

Diagnosis of polyps typically involves medical imaging techniques like colonoscopy, endoscopy, or nasal endoscopy, depending on the suspected location. A biopsy, where a small sample of the polyp is removed and examined under a microscope, is usually performed to determine if it is cancerous or precancerous. Treatment for polyps often involves removal, especially if they are large, symptomatic, or have precancerous features. The method of removal depends on the polyp's size and location, and can range from endoscopic removal during a colonoscopy to surgical excision. Regular screening is recommended for certain types of polyps, such as colorectal polyps, to detect and remove them before they become cancerous.
