Diagnosis of of cancer Diagnosis of cancer is done by observing the symptoms shown by the patient. The physician may suggest blood tests, endoscopy, X-ray, ultrasonography, CT scan or MRI scan to find out the location and size of the tumor. Confirmatory tests are done through biopsy which involves microscopic examination of the samples from the suspected area. Biopsies are painful and are conducted in the presence of local anesthesia. Biopsies involve cutting out a piece of tissue from the suspected area with the help of a scalpel.23 Pathological examination of the biopsy helps us to know whether the tumor is ‘benign’ or ‘malignant’. After the diagnosis, staging tests are done to know the location, growth of cancerous cell to the nearby structures and spread to different parts of the body. CT scan is done to detect cancer in different parts of the body like liver, lungs, brain, lymph nodes etc. MRI scan is done to detect cancer of the brain, bone and spinal cord.
