American oncologists have come to the conclusion that oral contraceptives increase the risk of developing breast cancer by 50%. Some tablets containing high levels of estrogens increase the risk of breast tumors three times. Scientists from the Fred Hutchinson Cancer Center found that oral contraceptives containing the female sex hormone estrogen, significantly increases the risk of developing breast cancer.
At moderate doses of estrogen the risk increases by 50%, while high - triples. Note that oral contraceptives, which contain low levels of the hormone does not entail additional risk of breast cancer. The study involved 23,000 women, and the study itself is said to have become the first, who studied the effects of oral contraceptives in the 1990s and 2000s, the health women.
The scientists compared 1,102 women who were diagnosed with breast cancer, with 21,952 of those who do not have the disease. Cancer victims were between 20 and 49, and they were delivered in diagnoses between 1990 and 2009. The study authors emphasize that women should be especially careful in the choice of contraceptive methods.
female hormone estrogen has long been known as "fuel" for breast tumors, estrogen and additional doses ingested together with contraceptives, are particularly dangerous. However, these studies do not mean that women should abandon the usual tablets. However, this problem can be discussed with a general practitioner or a narrow specialist.
