Research output: Chapter in Book/Report/Conference proceedingChapter


Pregnancy and lactation represent the most effective protective elements against breast cancer; counter-intuitively breast cancer incidence shows a small but noticeable increase up to 5 years after delivery. The cumulative effect is however favourable and women show a reduction in breast cancer risk which is proportional to the total duration of lactation and to the number of full-term pregnancies.
