WHAT IS CANCER
Our body has different types of cells which grow and multiply several times in a day to maintain normal function.
Occasionally this cell division is affected and creates a wrong cell or an abnormal cell, these divide further in an uncontrolled way affecting the other parts of the body.
These cells which divide abnormally are called cancers.
These cells can locally infiltrate the adjacent organs or invade the blood and lymphatic system and cause spread or metastasis.
Cancer can occur in almost all parts of the body and they are categorized mainly from the cell in which they begin.
Cancer arising from epithelium or covering of an organ - CARCINOMA
Cancer arising from connective or supportive cells (E.g.: bone, muscle, ) - SARCOMA
Cancer arising from cells which produce blood(bone marrow) - LEUKAEMIA
Cancer arising from cells of immune system - LYMPHOMA and MYELOMA
Cancer arising from nervous system - ASTROCYTOMA, GLIOMA
HOW DOES CANCER START
By damage to DNA - the genetic material in the cell
By interfering with cell division and other controlling mechanisms of the cell.
Damage to DNA can be caused by certain hydrocarbons, chemicals which are present in tobacco for example, radiation or due to certain chemical action in our body when the built in protection mechanism fails in our body.
Certain substances for example stimulate cell division causing damage to DNA and causing mutation.
Any factor which leads to the above can produce cancer.
