If a doctor suspects that you have cancer, he/she will suggest a number of laboratory tests to be sure of the presence of cancer in your body. The pathologist examines the samples of blood, urine, other body fluids or tissue for abnormal cells or tumour markers. These help to determine whether a person has cancer or there is a precancerous condition. A doctor is also able to screen high-risk patients, determine the cancer stage, decide the different treatment options and can understand whether the treatment is giving positive results. It is also possible to understand from these tests whether it is a relapse of previous cancer or a new one. When one of my relatives asked about a proper place for cancer diagnostic tests, I suggested the name of a reputed pathology centre near me.
