According to the data go to 2018, about seven percent of all cancer cases (30.567) on Obesity. Especially large is the influence of accordingly, in the case of malignant tumors of the uterus, the kidney and the liver. As overweight people were considered in the calculations, starting from a BMI of 25.
4. Unhealthy Diet
Food influences in several Ways the risk of cancer: it may contain carcinogenic substances, caused by the Smoking and curing of meat. In addition, a well-balanced diet but also contributes indirectly to a lower risk of cancer, by helping to maintain optimal weight.
In the Definition of a healthy diet the scientists based on the recommendations of the World Cancer Research Fund (WCRF). Therefore, adults should:
- at least 32 grams of fiber per day eat
- every day at least 400 grams of fruit and non-starchy vegetables (potatoes don’t count) eat,
- Sausage to strike,
- red meat to less than 500 grams per week limit, and
- to take less than six grams of salt per day.
According to the estimates, go to 2018, eight percent of all cancers (total 34.162 cases) on a diet back, this rules fails. The greatest impact of fibre deficiency in the consumption of sausage, as well as a lack of fruits and vegetables. Salt and red meat contribute only slightly to the cancer burden, the researchers write.
5. Lack of exercise
The Germans are muffle movement, and that’s been a Problem for years. In order to reduce the risk of cancer as far as possible, should adults, according to the WCRF at least 150 minutes a week moderate or intensive move. The only a fraction. The result, according to the estimates, more than 27,000 cancers, approximately six percent of all cases. The protective effect of exercise is closely linked to a balanced diet – it helps to avoid Obesity and counteracting inflammation.
6. Infectious diseases
For evidence that human papilloma virus (HPV) can cause cervical cancer, received the German researcher Harald zur Hausen 2008 Nobel prize. In addition to HPV doctors are familiar with today, a number of other pathogens that contribute to cancer. The bacterium Helicobacter Pylori, Hepatitis B and C, HIV and human herpes virus type 8.
All together according to the calculations, about five percent of all cancer cases in women (about 9900), and three percent of all cancer cases in men (around 7700). Around 90 percent of the diseases have decreased in two of the analyzed bacteria: HPV and Helicobacter Pylori. Prevention with HPV vaccination. Infections with Helicobacter Pylori are difficult to avoid, in addition, they often remain unrecognized. What would help: Targeted Tests and therapies.
The proportion is higher for women than for men, mainly due to the fact that cervical cancer is almost always based on HPV.
7. Environmental factors
At this point, the researchers examined environmental factors that can increase the risk of cancer and modified. Overall, one percent of all cancer cases (more than 5400) on the considered factors.
- Radon in indoor spaces is one in addition to Smoking to the most important causes of lung cancer. It decays after Inhalation in the lungs, where radioactive radiation is released. The inert gas is contained in the earth and can penetrate through the ground into the building. The burden would be achieved through stricter building codes reduce, the researchers write. Thus, in 2018, approximately 3200 of cancer could be avoided diseases. (The Federal office for radiation protection you will find a map of Germany to radon exposure.)
- Passive Smoking leads to estimated 2018 to 309 lung cancer cases.
- The fine dust were, on average, 23 percent of the population concentrations exposed to over the by the world health organization (WHO) recommended limit positions. Out to 2018 can be according to the calculations, a total of 1049 cases of lung cancer.
- Frequent Solarium visits explain to 2018, a total of 892 cases of skin cancer there. The influence of the solar radiation is likely to be significantly larger. For this purpose, representative data, which would have allowed calculations for the whole of Germany was missing, however, the researchers.
Conclusion: A majority of the preventable cases of cancer is caused by an unhealthy lifestyle, i.e. Smoking, alcohol, Obesity, lack of exercise, and a penchant for fast food instead of whole grain bread. The Good: These points are – in contrast to radon exposure, and infections – even the most easily influence. Nevertheless, even the most exemplary behavior does not provide a hundred percent protection against cancer.
