  Detection and treatment of cancer Early detection of cancers is essential as it allows the disease to be treated successfully in many cases. Cancer detection is based on biopsy and histopathological studies of the tissue and blood and bone marrow tests for increased cell counts in the case of leukemias. Biopsy ; In biopsy, a piece of suspected tissue cut into thin sections is stained and examined under microscope (histopathological studies) by a pathologist . Techniques of detection Techniques like radiography (use of X-rays), CT (computed tomography) and MRI (magnetic resonance imaging) are very use full to detect cancer of the internal organs. Computed tomography;   This technique uses X-rays to generate a three dimensional image of the internals of an object. Magnetic resonance imaging (MRI);  MRI uses strong magnetic fields and non-ionising radiations to detect accurately pathological and physiological changes in the living tissues.
