Early child cause breast cancer

Scientists have discovered another risk factor that can cause breast cancer. The probability of occurrence of this disease is 60% higher among young mothers who give birth in less than 15 years after the first menstruation. This fact raises serious questions about the safe period of the first conception.

Inherently breast cancer is a particularly aggressive disease. Its growth and distribution does not depend on the presence of hormones, particularly estrogen. The study suggests that women in pre-menopausal women, the risk is higher than in postmenopausal women.

In this same study obtained evidence that breastfeeding produces a specific protective mechanism against breast cancer. To clarify some details still need to conduct additional observations and experiments.

In this study involved nearly two thousand women. Age scale consisted of representatives from 20 to 44 years. More than a thousand of them have already had breast cancer - triple-negative or HER2 - and helped to answer experimental questions.
