I had very large fibroids and ended up having a hysterectomy, which was the best thing and gave me my life back. The consultant did tell me that fibroids continue to grow if oestrogen is present. Before my operation I had a few months of Zoladex treatment to shut off the oestrogen and help the fibroids to shrink a bit.
A few years after the op my ovaries declined due to menopause and I eventually started using Oestrogel.
