It has long been believed that pregnancy after a breast cancer diagnosis adversely affects prognosis. A study of 115 women with breast cancer who were followed for a mean period of 6 years revealed no significant difference in prognosis between those that became pregnant and those who did not. Surprisingly, a higher proportion of pregnant women were disease free compared with non-pregnant women, suggesting that pregancy after development of breast cancer might have a protective effect.
