Internal Factor and External Factor Cause Of Cancer


Internal factors

internal factor can cause of cancer is an error occurred replication of cells.  A genetic fault inherited from the parents . These errors usually result in cancer at an early age .

when a father has thyroid cancer, not usualy all of their son will experience the same thing, because cells undergoing genetic errors should be damaged first before they turn into cancer cells . Only individuals carrying the wrong cell genetics , are more at risk of developing cancer than those who do not have the gene mutation wrong .

Factor gene mutations are internal , not external factors can be prevented but can be prevented . According to WHO , 10 % - 15 % of cancers , are caused by internal factors and 85 % , caused by external factors . So , even if not 100 % , the actual cancer deaths can be prevented or avoided with avoid external factors .

External factors

External factors that can damage genes are viruses, air pollution , food , radiation , and comes from chemicals, fine chemicals added to food , or chemicals that come from pollution .

Chemicals are added to foods , such as preservatives and food coloring . How to cook also can convert food into chemical compounds that are harmful . Meat or fish grilled until charred , contain chemicals such as benzo - a- Piren , amen heterosoklik , dioxin , etc. .

Germs that live in food can also spread toxins , such as aflatoxins in nuts , is closely related to liver cancer .

The more often the virus body the more likely a normal cell into a cancer cell . Detoxification process carried out by the body , in the process often produces a compound that is more harmful to the body , ie compounds that are radical or korsinogenik . Korsinogenik substances can cause damage to cells
