However, according to the National Cancer Center , there are several factors that can increase a person suspected of cancer.

Whereas the causes of cancer are:

heredity factors

Genetic factors will cause some families will have the risk of certain cancers when compared with families with no history of cancer.

Environmental factor

Several environmental factors that can cause cancer are smoking, ultraviolet rays, and ionizing radiation. Smoking is a bad habit that can improve oral cancer, lung cancer, larynx (voice box), as well as the bladder. While exposure to ultraviolet light and ionizing radiation (the carcinogenic) used in X-ray in generated from nuclear power plants and atomic bomb explosions that can reach very long distances.

Dietary factors

Another factor that causes cancer can also be caused by food that is made from chemicals. Especially the risk of cancer of the digestive tract.

virus attacks

Viruses that can lead to cancer which Papilloma Virus, cytomegalovirus, hepatitis B virus 4, Epstein-Bar 5, Retro Virus in humans eg HIV virus which causes lymphoma and cancers of the blood.
