Cancer is disease in-groupness marked with cell division that is is not in control and ability of the cells to groan other biological network, either with direct growth in adjacent network ( invasion) or with migration of cell to far place ( metastasis). Growth that is is not in control the is caused DNA damage, causes mutation in vital gene controlling cell division. Some fruit of mutations possibly required to change normal cell become cancer cell. The mutations often is resulted chemical agent and also physical of so-called carcinogen. Mutation can happened spontaneously ( obtained) and or is endowed ( mutation germline).

Cancer can cause many different symptoms, bases on its location and character from ferocity and whether there are metastasis. a determining diagnosis usually requires microscopic inspection of network obtained with biopsy. After diagnosed, cancer usually is taken care of with operation, chemotherapy and/or radiation.

when sleazy, most cancer causes death; cancer is one of the root cause death in developing countries. Most cancer can be taken care of and many healed, especially when treatment is started since beginning. Multiform of cancer relates to environmental factor that is actually can be avoided. Tobacco smoking can cause many cancers from other environmental factor.

Tumor refers network mass that is below par, but cans be in the form of " malignant" ( haves the character of cancer) or " tame" ( doesn't have the character of cancer). Only tumor raised hell capable to groan other network and or having metastasis.
