Fibroids (myomata) of the uterine wall can cause pain, heavy bleeding, anemia, and lead to failure of implantation of a fertilized egg or to repeated early miscarriages. 99.5% of fibroids are benign. 20% of women over 30 have some evidence of fibroids. Most women have no symptoms at all.
CONTRACEPTION: The LNG IUD has been used to control heavy bleeding from fibroids and may decrease fibroid size. Some combined pills are associated with reduced risk of hospital referral for fibroids [Guillebaud p.173 Contraception Your Questions Answered 2009]. Low dose COCs do not stimulate fibroid growth but do decrease menstrual bleeding. [Friedman, A J Obstet Gynecol 1995]. DMPA effectively decreases blood loss from myomas and may shrink myomas [Venkatachalam J. Obstet Gynecol 2004].
