Fibroids are categorized from the place or area where they develop. All fibroids begin as a growth somewhere within the uterine muscular wall. The symptoms caused by fibroids depend on where they grow in the wall and how big they are.
These fibroids grow within the muscular wall of the womb.
These fibroids tends grow outwards, towards the pelvic cavity from the outside wall of the womb. The size of the fibroid of this category is larger than the rest and these can press on the organs surrounding the uterus such as the bladder or rectum. Sometimes, they may grow large enough to push outward and cause a noticeable swelling in the abdomen.
Growing from the inner wall of the womb these fibroids takes up the space within the uterus and affects pregnancy. These grow directly below the lining cells of the uterus and may lead to heavy or irregular bleeding.
Some fibroids may form on stalks that connect them to the uterus. These are called pedunculated fibroids and can be either submucosal or subserosal in location.
Cervical fibroids grow in the wall of the cervix very near to the neck of the womb and are quite complicated to eliminate without damaging the adjacent area.
