Uterus Fibroids & Adenomyosis

Uterus Fibroids

Uterus Fibroids are the most common benign muscular tumors (non-cancerous) that can grow on your uterus.
Fibroids can vary a lot in size, shape, and location. They can show up in your uterus, uterine wall, or on its surface. They can also attach to your uterus by a stalk- or stem-like structure.
Uterine fibroids usually appear in women of childbearing age — generally between 30-40 years old, up to 40-50% of women during menopause likely to have uterine fibroids.


Fibroids may cause very mild symptoms, no symptoms at all, or symptoms that are severe. The most common symptoms of uterine fibroids include, heavy, prolonged or painful periods, pain in the lower abdomen or back, painful sex, frequent urination, discomfort in the rectum and likely to cause infertility.


Endometriosis happens when endometrial tissue is discovered outside the uterine cavity.
If endometrial tissue occurs in the myometrium, it is called adenomyosis. If it is discovered at the ovary, it is so-called endometrioma or chocolate cyst.
