Up until now is still a puzzle as to why someone has cancer, others are not. They already know, cancer can be caused by many factors, and evolving in many years.
Research proves that that several factors can increase a person's risk of getting cancer. Fortunately most of the risk factors that can be avoided, controlled, and controlled, by choosing the right lifestyle.
Here are the factors most likely to cause cancer. Other factors are still a lot, unfortunately not yet possible to be explained it all here.
age:
Most cancer strikes people aged over 60 years. But not a few people who were much younger, even children under the age of five, who also had cancer.
Tobacco:
Smoke cigarettes / tobacco smokers who inhaled either active or passive smoking can cause lung cancer, cancer of the vocal cords, cancer of the mouth, throat, kidney, bladder, esophagus, stomach, pancreas, leukemia, and cervix. Not just the smoke, often smelling of tobacco can cause cancer, and chew / suck it (eg in the form of fringe-Jw) can cause oral cancer.
Sunlight:
Morning sun is good for health. But the afternoon sun, which contains ultraviolet, can cause skin cancer. Use an umbrella, hat, and clothes that cover your body as much as possible to protect themselves from ultraviolet rays. Skin that is not protected, should be smeared with sunscreen containing sun protection factor (SPF) of at least 15.
Ultraviolet rays can penetrate glass, thin clothes, can also be reflected by sand, water, snow, and ice. Keep in mind, that the ultraviolet lamps are sold in stores can also cause cancer, you know.
Chemical Substances:
Many chemicals are added in the food / beverage modern can lead to cancer, for example preservatives, artificial coloring, artificial sweeteners, artificial flavorings. In fact, almost all food / beverage production factory or sold in the shop / restaurant contain additional substances.
But the food prepared at home was not necessarily free of cancer risk. Since most vegetables and fruits grown by relying on artificial fertilizers and pesticides. Foods that are grilled, baked, or fried in cooking oil also has the potential to cause cancer. So is water polluted by detergents and other chemical wastes (although it has been cleared up).
Substances other cancer-causing chemicals can enter the human body through air, such as benzene, asbestos, cadmium, nickel, vinyl chloride, and so on.
Viral and Bacterial Infections:
Some types of viruses and bacteria can increase the risk of cancer, among others:
Human papilloma virus (HPV), a major cause of cervical cancer and may increase the risk of other types of cancer. Hepatitis B virus and hepatitis C can lead to liver cancer. Virus human T-cell leukemia / lymphoma (HTLV-1) increases the risk of lymphoma and leukemia. Human immunodeficiency virus (HIV) which causes AIDS is known as this increases the risk of lymphoma and Kaposi's sarcoma.
Epstein-Barr virus increases the risk of contracting lymphoma. Human herpes virus 8 (HHV8) may cause Kaposi's sarcoma. Helicobacter pylori causes gastric and intestinal injury can also cause cancer along the digestive tract.
To reduce the possibility of contracting the virus / bacteria, avoid sexual promiscuity, also do not exchange toothbrushes, needles, combs, cutlery, etc..
Diet, Obesity, and Lack of Motion:
Too much consumption of red meat and salt can increase the risk of colon cancer, rectum, and other cancers in the abdominal area. Instead consume lots of vegetables and fruits may reduce the risk of cancer along the digestive tract.
Obesity and inactivity can lead to breast cancer, endometrial, kidney, colon, and esophagus. To prevent this, daily exercise for at least 30 minutes.
Alcohol:
Consumption of alcohol can lead to cancer of the mouth, throat, esophagus, vocal cords, liver, and breast. But once in a while to eat the tape, it does not matter really.
Hormone:
Excessive estrogen hormones in the body can increase the likelihood of contracting uterine cancer and breast cancer. Being hormone progesterone can prevent endometrial cancer, but increases the risk of breast cancer. Both types of hormones are widely used as ingredients of birth control pills or hormone replacement therapy in postmenopausal women. Long-term use can reduce the risk of uterine cancer and endometrium, but increases the risk of breast cancer and liver cancer.
Family History:
Trigger factors above will cause cancer if you managed to create a gene in the cell nucleus is changed (mutated). If the immune system is unable to repair or destroy these mutated genes, these genes make normal cells turn into malignant cells, which in turn develop into cancer.
Sometimes the nature of the gene is then passed down to children, which makes the child has an abnormal gene. Notwithstanding the abnormal gene will not necessarily develop into cancer, because it still depends on the presence or absence of other triggers and least powerful body resistance. Moreover, not all types of inherited cancer. Only certain types of cancer who have inherited tendencies, ie, melanoma (skin cancer), breast, uterus, prostate, and colon.
