Since this seems to be a topic that generates many questions amongst us girls, I thought I would post a link here to an excellent DAN article that covers most of it.
Topics covered are cancers, breast issues including breast feeding and diving,(is that what I have to look forward to, pee-valves for my nipples while diving in a drysuit? ) pregnancy and diving, endometriosis, breast implants and diving, menstruation, birth control, osteoporosis, etc, all as it relates to us girls and diving.
Here is the DAN article.
