  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.

  Cancer Cancer  is one of the most dreaded diseases of human beings and is a major cause of death all over the globe. More than a million Indians suffer from cancer and a large number of them die from it annually.   Causes of cancer;   In our body, cell growth and differentiation is highly controlled and regulated. In cancer cells, there is breakdown of these regulatory mechanisms. Normal cells show a property called cotnact inhibition by virtue of which contact of other cells inhibits their uncontrolled growth. Cancer cells appears to have lost this property. As a result of this, cancerous cells just continue to divide giving rise to masses of cells called tumors. Tumors are of two types;                     1.   Benign tumor and                     2.   Malagnant tumor Transformation of normal cells into cancerous neoplastic cells may be induced by physical,chemical or biological agents. These agents are called carcinogens.   Physical carcinogens; Ionising radiations like X-rays and
