(CBS) - Breastfeeding for more than six months may protect against breast cancer in women who are non-smokers.
New research from Spain looked at about 500 breast cancer patients and found women who had children and breast fed were diagnosed with breast cancer at a later age. They also found non-smoking women who breast fed their babies for longer than six months were more likely to be diagnosed with breast cancer later in life.
Women who smoked tended to be diagnosed with breast cancer young and got no benefit from breastfeeding longer.
