Cancer Insurance
Cancer is a disease in which group of cells from the body shows uncontrolled growth and become cancerous. These cancerous cells invade other body parts through blood or lymph. Normal cell follow the cell cycle i.e. growth, division and finally death but there are some cells in the body which shows growth and division, these cells do not shows programmed cell death and divides continuously to form lump or tumor.
90% of the cancers are developed because of today's modern living style, genetic structure, unsafe physical relations and the environment in which we are living. There are many causes of the cancer but some of them are as follows.
Genes
Cells become cancerous i.e. shows uncontrolled growth because of breaking or mutation of DNA. There are genes on DNA which controls the cell cycle for the normal cells, if any changes occurred in the DNA, cell becomes cancerous. There are four genes which controls cell division
- Oncogenes give permission to the cell when to divide
- Tumor suppressor genes performs function exactly opposite to the oncogenes, it stops cell division
- Suicide genes control cell death
- DNA repair genes performs important function of repairing the damaged genes
Cell becomes cancerous when the cell is not able to repair or correct the damaged DNA. It disturbs cell cycle and leads to cancer.
Carcinogens
There are group of substances called carcinogens that causes damage to the DNA. When body is exposed to the carcinogens, free radicals are produced in the body; these free radicals try to pull electrons from molecules of the body. This activity disturbs the functioning of cells and it leads to cancer.
- 30% of cancer deaths are caused by smoking and chewing tobacco, containing chemical called nicotine
- Asbestos is a fiber used in the construction work and in industries, it scratches lungs causing lung cancer
- X-rays and gamma rays can damage DNA, if body is exposed to them for a long period of time
- Smoke released from vehicles can cause cancer related to the respiratory system
Acrylamide
Acrylamide is naturally producing by-product after cooking food can leads to cancer.
- Acrylamide is produced if food is cooked on high temperature like boiling, frying and baking. Eating potato chips, French fries increase the chances of cancer
- Cigarette smoke also produce acryl amide
Genetic:
Cancer may be genetic, if you have family history of cancer then; there is possibility that you could get cancer or probability of developing cancer. It happens when mutated or damaged gene is transfer from one generation to the next.
Human Papillioma Virus (HPV):
Human Papillioma Virus is developed from unsafe sex. It increases the chances of cancer related to the reproductive system like cervical, anal, vulvar and vaginal cancer.
Sun:
Exposure to Ultra Violet (UV) rays for long period of time can increase the chances of skin cancer
Age:
Advanced age is one of the reasons for cancer. At this stage, some changes are occurred in the genes accidentally or by the carcinogens. Damaged DNA containing becomes cancerous. Over weight
Balanced diet is very important for maintaining healthy body. Most of the people are overweight because of lack of physical activity and diet containing plenty of fats, fast food and meat. Some persons drink alcohol and eat only non-veg food, this type of lifestyle increases the chances of cancer. Immune system
Some people may have week immune system because of AIDS or genetic syndrome. In organ transplant operations immune system is suppressed to avoid rejections of foreign organ; it also raises possibility of cancer.
