Cancer: Diagnosis

Early detection of cancer can greatly improve the odds of successful treatment and survival. A biopsy is a medical test commonly performed by a surgeon, interventional radiologist, or an interventional cardiologist involving sampling of cells or tissues for examination. Physicians use information from symptoms and several other procedures to diagnose cancer Imaging techniques such as X-rays, CT scans, MRI scans, PET scans, and ultrasound scans are used regularly in order to detect where a tumour is located and what organs may be affected by it. A breast MRI is not a replacement for mammography for high risk women. Instead, it should be used as a complementary screening tool. This is because although an MRI may be more likely to find cancer than mammography, it often misses some cancers that mammography easily detects. For women with an average risk of breast cancer, mammography is still the standard method for diagnosing early-stage breast cancer. Doctors may also conduct an endoscopy, which is a procedure that uses a thin tube with a camera and light at one end, to look for abnormalities inside the body.
