Nowadays there are several new methods to diagnose cancer. The diagnosis is usually made by pathologists, oncopathologists or radiologists. There are a number of medical gadgets available today which can help to diagnose cancer in a better way. The first step in diagnosing the cancer is the use of imaginary techniques such as X-ray, MRI scans and ultrasound scans. This is the basic step to diagnose the location of the tumor and the organ affected with the tumor. Furthermore, the doctors may conduct an endoscopy which is an imaginary technique in which a thin tube with a tiny camera is inserted in the affected part of the body. This will allow the medical specialists to check the affected area thoroughly. The doctors may conduct a biopsy in which a small sample of tissue is taken with the help of a fine tipped needle. After the biopsy, the sample will be sent for a lab test in which the sample will be checked under a microscope to diagnose whether it’s a cancer or not. Other tests include the blood test and PAP test. After the diagnoses, the doctors may suggest the treatment which is based on the cancer stage and grade. There are different types of stages in cancer which are termed as TNM (0-4) where zero is considered as the early stage of cancer while the level 4 tumor is considered as a late stage of cancer, hence untreatable.
