Precancerous lesions are often discovered through various screening methods and diagnostic tests. These include:
- Pap Smear: This test is used to detect cervical dysplasia by collecting cells from the cervix. - Colonoscopy: This procedure examines the colon and rectum for polyps and other abnormal growths. - Biopsy: A sample of tissue is taken from the suspicious area and examined under a microscope. - Dermatoscopy: This is used to examine skin lesions more closely and may be followed by a biopsy for confirmation.
