Cancer:
The name for diseases in which the body's cells become abnormal and divide without control. Cancer cells may invade nearby tissues. And they may spread through the bloodstream and lymphatic system to other parts of the body.

Causes:
There is no one single cause of any disease. We can only talk about cofactors, causative agents and life situations that like peaces of puzzle come together and promote disease of cancer. There are hundreds of cofactors and causative agents that each have casual relationship to

poor immunity,
poor health,
accumulation of toxins inside body,
poor thoughts
each one have been mistakenly called cause of cancer.

Most important co-factors are:

lack of knowledge,
poor thoughts,
lack of consciousness,
lifestyle,
diet,
exposure to toxins, life situations.

We are only able to recognize the largest pieces of this puzzle, while some smaller pieces, that all together may cover an area as big as that area covered by the large pieces of the cancer puzzle, often stay unrecognizable.

Prevention of Cancer:
1.Tobacco is the single largest preventable cause of cancer in the world today. It causes 80-90% of all lung cancer deaths, and about 30% of all cancer deaths in developing countries, including deaths from cancer of the oral cavity, larynx, oesophagus and stomach.

2.Dietary modification is another important approach to cancer control. There is a link between overweight and obesity to many types of cancer such as esophagus, colorectal, breast, endometrial and kidney.

3.Regular physical activity and the maintenance of a healthy body weight, along with a healthy diet, will considerably reduce cancer risk.

4.Infectious agents are responsible for almost 22% of cancer deaths in the developing world and 6% in industrialized countries. Viral hepatitis B and C cause cancer of the liver, the bacterium Helicobacter pylori increases the risk of stomach cancer.

5.Avoiding excessive exposure, use of sunscreen and protective clothing are effective preventive measures of all types of cancer of the skin.

6.Asbestos can cause lung cancer; aniline dyes have been linked to bladder cancer; and benzene can lead to leukaemia. The prevention of certain occupational and environmental exposure to these and other chemicals is another important element in preventing cancer.
