Almost half of all cancer cases in the UK could be avoided, according to a study by British scientists as they were caused by smoking, excessive alcohol consumption and poor diet.
Every year in Britain, 130,000 diagnosed cases of cancer. In this case, according to the report of British Centre for Research on Cancer Cancer Research UK, among the risk factors leading smoking: it causes the emergence of cancer in 23% of male patients and 15.6% of female patients.
The next most common cause of cancer published in the journal British Journal of Cancer study, called the lack of fresh fruits and vegetables in the diet. This problem is mostly for men, while for women in second place — overweight.
The report's authors stress that it is the result of the large-scale study to date of the causes of cancer.
"Many people tend to think that cancer is associated with a bad heredity or occurs for no apparent reason, by the will of evil fate. In this approach, the emergence of the disease seems to matter of bad luck, "- said the head of the research team, Professor Max Parkin.
"But if you look at our data, it is clear that 40% of all cancers are dependent on lifestyle and could be prevented" — continues the scientist.
The importance of fruits and vegetables
We did not expect that, for men it is the consumption of sufficient amounts of fruit and vegetables will be so important for the prevention of disease. And we also do not think that women weight problem will be more important than alcohol "

In this case, to protect against cancer, the best solution would be for men to quit smoking, eat more fruits and vegetables and reduce the amount of alcohol consumed.
Women scientists advise as to stop smoking and to monitor their own weight
"We did not expect that for men it is the consumption of sufficient amounts of fruit and vegetables will be so important for the prevention of disease. And we also do not think that women weight problem will be more important than alcohol "- says Max Parkin.
All scientists counted 14 factors that affect susceptibility to cancer. All of them are related to the environment and lifestyle.
Approximately 100,000 cases of cancer in the UK (or 34%) are connected to smoking, poor diet, obesity and excessive alcohol consumption.
One of the 25 cases associated with poor working conditions, for example, work with chemicals.
Factors influencing the occurrence of some types of tumors are well known. For example, everyone knows that smoking causes lung cancer.
However, the other links of the disease and risk factors people know much less.
According to scientists, about 10% of cases of breast cancer associated with being overweight or obese.
Half of all malignant tumors of the esophagus are due to a lack of fruit and vegetables in the diet, and only 20% of cancers of the esophagus triggered by excessive consumption of alcohol, while 20% of cases of gastric cancer associated with the patient's predilection for salty foods.
In this case, the appearance of certain types of tumors were triggered mainly by a single circumstance, but is connected with the general way of life.
Cancer of the gall bladder, for example, generally has nothing to do with bad habits.
Different rates for men and women
In the study of the causes of cancer researchers used data on cancer incidence in the UK for 15 years, from 1993 to 2007.
In the case of men, the incidence of cancer has been linked mainly to a lack of fruit and vegetables in the diet (6.1%), unfavorable factors occupations (4.9%), alcohol in large amounts (4.6%), overweight ( 4.1%), prolonged exposure to the sun and ultraviolet light (3.3%).
Cancer in women mainly precipitated by overweight and obesity (6.9%), infection (3.7%), prolonged exposure to the sun (3.6%), lack of fruit and vegetables in the diet (3.4%) and alcohol (3.3%).
