Until today, global medical statistics for many years reported that breast cancer is the leading cause of death in women. Each year around 1.5 million new cases of this disease are detected in the world, and this figure increases every year.
This is connected both with the increase in the incidence and with the improvement of the diagnosis of breast cancer in civilized countries. Obviously, therefore, the incidence rate in developed countries is higher. But on the other hand, if we analyze the structure of cancer incidence, then in civilized countries there is a much smaller percentage of neglected cases, and, accordingly, a much higher treatment efficiency, patient survival, many times more cases of complete cure.
For the first time in the history of European countries, "primacy" took on lung cancer in women. The latest statistical analysis, conducted in Europe, states the decline in breast cancer mortality rates to 14.22 (per 100,000 population) and its increase from lung cancer to 14.24. Scientists explain this not only by changes in demographic status – the aging of the population and the associated increase in the incidence of lung cancer, and other, more weighty reasons have been established.
Researches of scientists from Italy and Switzerland
The absolute fact is the aging of the population in Western countries, which in itself implies an increase in cancer incidence with age. But another, more important pattern of the increase in the incidence of lung cancer among women in civilized countries has also been established. Scientists at the University of Milan, together with colleagues from Switzerland and the American Medical Association, conducted research among the female population, which resulted in a dramatic increase in the number of female smokers in recent decades: from 17% to 24%, while among men it decreased from 41% to 31%. The largest percentage of women smokers in Greece, and in some countries, for example, in Sweden, heavy smokers are more among women than men. Women of Great Britain and Poland are also breaking records in smoking addiction.
Smoking is a major risk factor
Investigating the causes of other cancers, such as pancreatic cancer, cervical cancer, also found that it is the "privilege" of tobacco lovers. Absorbing through the alveoli into the blood, toxic products of tobacco smoke, including nicotine, have a carcinogenic effect on a wide variety of organs, primarily on the endocrine system. But it is the lungs that are most susceptible to the effects of smoking, because tobacco smoke goes there in its entirety, consisting not only of nicotine, but of carcinogenic tar, toxins, and soot. Therefore, smoking is a major risk factor in the development of lung cancer.
The conducted studies are only preliminary, they will last for 3-5 years. But even today they give rise to sound the alarm, and should oblige the leadership of the health authorities to develop more effective measures for the prevention of female tobacco dependence and its treatment.
