Cancer is deadly disease which is caused due to uncontrolled growth of the cells and forms from the extra mass tissue known as tumour. The loss of apoptotic nature by the cells in their metabolic pathway leads to cancer. Cigarette smoking, tobacco intake, alcohol intake, poor diet and exposure to UV rays lead to cancer. Different organs can be effect by cancer cells like lungs, kidney, eyes, heart, brain etc. Cancer cells also spread in blood stream and causes blood cancer. The person who works in the chemical factories, nuclear reactors, drainage system and mining are most prone to cancer. The most cancer causing agents are aluminium, arsenic, radon, lead and lead compounds, titanium dioxide, Ethidium Bromide, Cobalt with tungsten carbide, Welding fumes and Indium phosphide. Treatments such as surgery, chemotherapy and radiation therapy, bone marrow transplantation are used to treat cancer in different stages.

CANCER:

  • Cancer is one of the dreaded diseases that post serious threats to human life. It is a disease whose disease is not yet discovered fully and still is under research.
  • Cancer occurs due to mutations in genes of cells. Mutation means a change in the normal genetic code, which leads to the production of abnormal proteins, as well as can boost up cell metabolic rate, or rate of division.
  • Cancer cells do have a high rate of cell division without any contact inhibition. This leads to formation of tumors, which later bursts and cancer cells travel to distant places through the blood. This is called metastasis.
