What are the main techniques used in cancer diagnosis?
Cancer diagnosis involves a combination of techniques to accurately identify the presence and type of cancer. Key techniques include:
Imaging techniques such as X-rays, CT scans, MRI, and PET scans, which help visualize the tumor. Biopsy, where a small sample of tissue is removed for examination under a microscope to determine if cancer cells are present. Blood tests for tumor markers, which are substances produced by cancer cells that can be detected in the blood. Endoscopy, a procedure where a flexible tube with a camera is inserted into the body to look at internal organs directly. Genetic testing to identify mutations in genes that may indicate a predisposition to certain cancers.
