Breast cancer is one of the most significant diseases in women, not only because of the high frequency and severity, but also because of the special relationship of women to breast and even in the absence of any disease. Home biological function of the prostate – produce milk (lactation) for feeding the newborn child. Dairy gland – is also important “component” female body image, and has great social significance as a symbol of motherhood, femininity and sexual attractiveness.

Thanks to numerous publications in newspapers, magazines, discussing the problem on television and radio, many women know of the existence of breast cancer. However, much of women’s “population” is not aware of the basic facts concerning breast cancer: how often and why it arises, what are the early signs and symptoms of breast cancer, what treatments are applied and how well they work.

Those or other forms of breast cancer (and their more than 30 species) can meet half the female population (ie every second women over 30 years). Fortunately, the vast majority of them benign and does not endanger the health. Malignant tumors (including breast cancer) are ten times less, but still are the leading cancer pathology in women older than 40 years.

Suffice it to say that in the world each year more than 1 million new cases of breast cancer, but in Russia – more than 50 thousand Over the life of one of the eight U.S. residents ill breast cancer. In our country, these statistics will be preferable: so only one out of 17 residents of St. Petersburg diagnosed breast cancer with an average life expectancy of more than 70 years. And yet, this high level of morbidity.

Generally XX in the last quarter. characterized by changes in morbidity related, on the one hand, the apparent increase in life expectancy (mainly in the developed countries of Europe and America), and on the other – with success in the prevention and treatment of infections. At first the plan for reasons of death came cardiovascular disease and tumor, often occurring among older people and associated with the emergence of their exchange and endocrine disorders.

Along with increasing frequency valid for breast cancer, lung, noted the apparent decline in the number of newly registered patients with stomach cancer, esophagus, cervix. Estimates, one can not expect continuous, uninterrupted and unlimited increase in morbidity in the long run. It is only a growth of some diseases and a significant decrease compared with the weight of others.

The maximum levels of performance in the U.S., New Zealand, Canada, Western Europe, the minimum – in Japan. The most dramatic contrast of breast cancer when comparing performance in the U.S. and Japan – 6:1 respectively. In many territories of the former USSR breast cancer has circulated widely for several years. Low levels of morbidity noted in the Central Asian Republics and Kazakhstan, high – – in the Baltic region, in St. Petersburg, Moscow, the Ukrainian otherwise, Northern Caucasus, in Georgia and Armenia.

Interestingly, among Japanese women born in the United States and in Hawaii, breast cancer and uterine body found in 5 – – 6 times more often than among the indigenous residents of Japan. This indicates that, in addition to constitutional and hereditary characteristics on the incidence of breast cancer have a certain influence factors external environment, in particular, especially food.

According to the World Health Organization (WHO) in the world every year shows about 1 million new cases of breast cancer. Number killed by the disease is approximately half of the total number of patients. Deaths from breast cancer could be significantly lower than if all countries were carried out mass preventive screenings for (screening) to improve early detection of curable forms of breast cancer.

Assessment demonstration screening programs, based largely on the application rentgenomammografii, found that deaths from breast cancer among women who took part in the screening, was at 30% -50% lower compared with women’s groups, which have not been breast cancer prevention. Countries in which at the state level for many years conducted a nationwide screening program that includes, along with training for women rentgenomammografiey techniques samoobsledovaniya, Medical examination of mammary glands (inspection, palpation), characterized by steady decline in deaths from breast cancer.

In most regions of the Russian Federation has continued growth of breast cancer, as morbidity and mortality from breast cancer because of insufficient coverage of modern prevention surveys. The life of tens of thousands of women would have been saved if they had participated in the survey preventive (screening).
