[Correlation of the probability of occurrence of breast neoplasms with solar activity].
A contingent with high incidence of precancerous breast diseases (1080 persons) was studied to assess the relationship between solar activity and 1) alterations in the relationship between women with early menarche and women with middle and late menarche (high and low risk of breast cancer respectively) and 2) incidence of benign breast diseases. It was established that population content alterations were wave-like and had statistically significant periods 3,5; 7 and 12 years, and correlate with Wolf number changes. Incidence of benign breast diseases in the group aged 20-50 years also changed periodically (T = 11 years) depending on the birth-year and correlated conversely with Wolf numbers at the birth-years. Incidence of benign breast diseases changes periodically in the population of women with early menarche with the period of 3.6 years, and in those with middle and late menarche--with the periods of 10.5, 3.2 and 4 years. There is a statistically significant correlation between the incidence of benign breast diseases and Wolf numbers in population of women with middle and late menarche.
