Lesbians and nuns have high rates of ovarian, breast and uterine cancer due to their not having children. San Francisco has the highest rate of breast cancer in the USA and the lowest birthrate. White career women also have a high rate of breast cancer.
Having children is a good way to reduce cancer of the reproductive organs and breasts.
From what I understand, risks of both types of cancers are greatly reduced by childbearing and nursing, both of which are activities that few nuns engage in. Even the Komen Foundation (despite their ties to Planned Parenthood-don't even get me started on that!) agrees that childbearing and nursing help reduce the risk of breast cancer (though there is, of course, NO link between abortion or the pill and breast cancer! None at all! /s).
Do you have a source on that?
Convent hot tubs?
I thought it was related to them not having and nursing babies.
So... if they did get this right, the formula for avoiding breast cancer should look a little like this:
1. Have one sex partner who has only had you as a sex partner.
2. Have 2 babies by the age of 25, nurse them for a year each.
3. Never take artificial hormones (including the pill)
4. Eat lots of greens.
Sounds like what grandma did.
