Cancer is a dreaded disease because of ferocity. However, cancer is not a disease that occurs in a short time. It should be a long process to transform normal cells into cancer cells. By knowing the process of its formation and the factors that trigger it, hopefully you can do prevention.
Our bodies are made up bodies and limbs are connected by blood vessels and lymph vessels. The limbs are composed of cells that are very small (hundredths of a milli-meter), which has a shape similar, but have different functions.
As white blood cells, which act against germs that enter the body. Red blood cells, serves to transport oxygen in the blood. Platelet function to freeze the blood to prevent bleeding.
Organelles within the cell there is one, is the cell nucleus that contain genes or DNA. DNA is the genetic material known as a carrier of hereditary characteristics. Cancer cells originate from a single gene that is damaged.
Tues damaged gene can be wild and develop continuously, so that from one cell into millions of cells and form new tissue. The new network is called a tumor or cancer.
Genes in the cell there is the so-called cancer genes (Oncogene), tumor suppressor genes (tumor suppressor genes), and genes in charge of repairing the defective gene, which gene repair. If one of these genes are damaged, then it could become cancerous.
Damage to the material commonly referred to as a gene or gene mutation can occur in several ways, both internally and externally.
Internal factors
An error occurred during replication in cells that die are replaced by new cells.
Is a genetic fault that descended from parents. These errors usually result in cancer at an early age.
If a mother has breast cancer, not necessarily all the daughters will experience the same thing, because cells undergoing genetic errors have suffered more damage before they turn into cancer cells. Only individuals carrying cell genetics is wrong, are more at risk of getting cancer than those not having the wrong gene mutation.
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 avoid the view of avoiding external factors.
External Factors
External factors that can damage the genes are viral, air pollution, food, radiation, and chemicals derived from both chemicals added to food, and chemicals that come from pollution.
The chemicals added in foods, such as preservatives and food coloring.
How to cook can also change the food into a harmful chemical compounds. Meat or fish are grilled until charred, containing chemicals such as benzo-a-piren, amen heterosoklik, dioxins, etc..
Germs that live in food can also spread toxins, such as poison aflatoxin in nuts, is closely related to liver cancer.
The more often the body attacked the virus more likely to normal cells into cancer cells.
Detoxification process carried out by the body, in the process often produces a compound that is more harmful to the body, are compounds that are radical or korsinogenik. Korsinogenik substances can cause damage to cells.
