How common are fibroids? Up to 40% of women past the age of 40 have fibroids and about 75% of women will never be aware of their existence unless they cause a problem.
Fibroids may or may not interfere with a potential pregnancy, depending on size, location, and potential to increase with the pregnancy, thus interfering with the placenta and fetus blood supply, etc. (Fibroids can grow larger during pregnancy, when estrogen production increases). In this case, interference may very well lessen your chances of carrying a baby to term. Only your physician can give you these answers, knowing what your specific circumstances and anatomy are.
In some cases, fibroids can return, even after a myomectomy. It is important that you have annual examinations with your physician (or sooner, if symptoms return). Bleeding can again cause anemia and should not go unchecked.
