Below German professor gave 7 preventable cancer factors:
1. Tobacco
This is the cause of 30% of all human cancers such as lung, larynx, esophageal, pancreatic cancer . In smoke there are over 70 different types of toxic chemicals that can cause cancer. Especially, there are 43 substances that have been shown to cause cancer, such as nickel, cadmium, benzopyren .
People who do not smoke but live with people who smoke and breathe in tobacco smoke are also at risk of smoking-related diseases , as do people themselves, especially women and children.

It causes many types of cancer such as cancer of the mouth, throat, larynx and breast. . The rate of liver cancer in men is the 3rd highest after lung and stomach cancer - the main reason is due to cirrhosis due to excessive alcohol consumption.
3. Malicious nutrition
High-fat, low-fiber diets increase the risk of colorectal and breast cancer . Food preservatives and colorants of chemical origin; Metabolic intermediates and food borne from fermented mold are also the cause of many types of gastrointestinal cancer such as stomach cancer, liver, colon .
Thi smoked, salted fish, pickled melon, salted fish, especially melon with many nitrates, nitrites are carcinogens of the esophagus and stomach. Rice and groundnut are two foods that are susceptible to mold. Aspergilllus flavus infects and secretes a toxic substance, afatoxin, which causes primary liver cancer.

4. Environmental pollution
In our country , plant protection chemicals - pesticides, herbicides commonly used in agriculture are risk factors for breast cancer and some other cancers . Agent Orange is also a potential risk factor for many cancers.
Chemicals used in industry cause about 2-8% of all cancers.
5. Physical agents
Ionizing radiation such as X-rays, radioactive substances used in medicine and a number of scientific fields are capable of damaging genes and developing cells. The impact of radiation causes cancer depending on the age, the amount of exposure and the organ being exposed. Radiation sensitive organs are thyroid and bone marrow.
Ultraviolet light in sunlight is the cause of skin cancer . People who often have to work outdoors lack the means of sun shelter are at higher risk of skin cancer than normal people.
6. Agents of viruses and bacteria
Hepatitis B virus is the cause of primary liver cancer . Human papilloma virus - HPV is also the cause of 70% of cervical cancer in women. This virus is sexually transmitted.
Helicobacter is a bacterium that plays an important role in gastric and duodenal ulcers and stomach cancer. This is a common cancer in Vietnam.

According to the World Health Organization, physical inactivity is responsible for 21-25% of breast and bowel cancer cases.
Physical activity creates people with good health, limiting illness, and prolonging life. For cancer, many studies confirm that physical activity is an important factor contributing to the prevention of cancer .
Thus, cancer is not caused by one but has many causes depending on each type of cancer. Smoking and an unreasonable diet are the two most important causes, causing the most types of cancer. Restricting exposure to cancer-causing agents is the most effective, simple and economical preventive measure in cancer prevention strategies in every country.
