Cancer develops from defects in fundamental regulatory mechanisms of the cell. Usually, cancer cells metastasize when it gets into the bloodstream or the lymph nodes and form secondary tumours across various sites in the body. Broadly divided into benign tumors (unable to metastasize) or malignant tumors (able to invade normal tissues), cancers are further defined and classified by their cell type, tissue, or organ of origin.
