• #1 Uterine Fibroids: Causes, Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/9130-uterine-fibroids

  Uterine fibroids (also called leiomyomas) are growths made of muscle and tissue that form in or on the wall of your uterus. These growths are usually not cancerous (benign) and are the most common noncancerous tumor in females. […] The exact cause is unknown, but healthcare providers believe the hormones estrogen and progesterone play a role. Most fibroids happen in people of reproductive age. Studies show that fibroids tend to grow when hormone levels are higher (like during pregnancy) and shrink when hormone levels are low (like during the transition to menopause). […] There are several risk factors that can play a role in your chances of developing fibroids. These can include: Obesity and a higher body mass index (BMI). Family history of fibroids. Not having children. Early onset of menstruation (getting your period at a young age). Late age for menopause. […] Most uterine fibroids don’t cause serious complications. However, the most common complications of fibroids are: Pain that becomes unmanageable. Swelling of your abdomen or pelvic area. Excessive bleeding. Anemia. Infertility (this is rare).

  Uterine fibroids are benign monoclonal tumors originating from smooth muscle cells within the uterus. The exact initiating factor of fibroid formation remains unclear. However, prevailing theories highlight the role of reproductive hormones, inherent abnormalities of the myometrium, and predisposing genetic variations that affect cell signaling pathways. […] Several molecular studies have identified specific gene mutations associated with leiomyomata, the most common of which is the MED12 gene located on chromosome X at position q13. The MED12 gene codes for one of the key proteins in the mediator complex (subunit 12) that regulates RNA polymerase II; a mutation in this gene occurs in approximately 70% of uterine leiomyomas. Other common mutations associated with leiomyomas include high mobility group AT-hook 1 and 2 (HMGA1 and HMGA2) and collagen type IV alpha 4 and 6 (COL4A4 and COL4A6).

  https://www.mayoclinic.org/diseases-conditions/uterine-fibroids/symptoms-causes/syc-20354288

  The exact cause of uterine fibroids isn’t clear. But these factors may play roles: […] Gene changes. Many fibroids contain changes in genes that differ from those in typical uterine muscle cells. […] Hormones. Two hormones called estrogen and progesterone cause the tissue the lines the inside of the uterus to thicken during each menstrual cycle to prepare for pregnancy. These hormones also seem to help fibroids grow. […] Fibroids contain more cells that estrogen and progesterone bind to than do typical uterine muscle cells. Fibroids tend to shrink after menopause due to a drop in hormone levels. […] Other growth factors. Substances that help the body maintain tissues, such as insulin-like growth factor, may affect fibroid growth. […] Extracellular matrix (ECM). This material makes cells stick together, like mortar between bricks. ECM is increased in fibroids and makes them fibrous. ECM also stores growth factors and causes biologic changes in the cells themselves.

  Uterine fibroids can cause symptoms ranging from mild to serious, including painful periods. Experts have a couple of ideas about why you may get them. […] Experts dont know exactly why you get fibroids. Hormones and genetics might make you more likely to get them. […] Hormones. Estrogen and progesterone are the hormones that make the lining of your uterus thicken every month during your period. They also seem to affect fibroid growth. When hormone production slows down during menopause, fibroids usually shrink. […] Genetics. Researchers have found genetic differences between fibroids and normal cells in the uterus. […] Other growth factors. Substances in your body that help with tissue upkeep, such as insulin-like growth factor, may play a part in fibroid growth. […] Extracellular matrix (ECM). ECM makes your cells stick together. Fibroids have more ECM than normal cells, which makes them fibrous or ropey. ECM also stores growth factors (substances that spur cell growth) and causes cells to change.

Likely there is an abnormality in which the cells in fibroid handle estrogen and progesterone. Fibroids are not caused by too much estrogen any more than fire is caused by too much air! […] What Causes Fibroids to Grow? Fibroids are sensitive to both estrogen and progesterone. Without these hormones most fibroids will shrink but not go away. Do not interpret this to mean that fibroids are caused by too much estrogen. That would be the same as saying that too much air causes fires because fires go out without air! Changes in fibroid cells cause fibroids to be more sensitive to normal levels of estrogen and progesterone.

  Uterine leiomyomas (also referred to as fibroids or myomas) are the most common pelvic neoplasm in females. They are noncancerous monoclonal tumors arising from the smooth muscle cells and fibroblasts of the myometrium. They arise in reproductive-age females and, when symptomatic, typically present with symptoms of abnormal uterine bleeding and/or pelvic pain/pressure. Uterine fibroids may also have reproductive effects (eg, infertility, adverse pregnancy outcomes). […] Uterine fibroids are described according to their location in the uterus although many fibroids have more than one location designation. The International Federation of Gynecology and Obstetrics (FIGO) classification system for fibroid location is as follows: Intramural myomas (FIGO type 3, 4, 5) – These leiomyomas are located within the uterine wall. They may enlarge sufficiently to distort the uterine cavity or serosal surface. Some fibroids may be transmural and extend from the serosal to the mucosal surface. […] Submucosal myomas (FIGO type 0, 1, 2) – These leiomyomas derive from myometrial cells just below the endometrium (lining of the uterine cavity). These neoplasms protrude into the uterine cavity.

  Fibroids are benign tumors that originate from the smooth muscle cells of the uterus, containing fibrous tissue, collagen matrix and sometimes calcium deposits. The exact cause of uterine fibroids is not known, although there are some factors that increase the risk of suffering from them. Hormonal causes: Myoma is a benign tumor dependent on hormonal production. After menopause, when hormone production in the ovaries decreases, new tumors do not usually appear and existing ones decrease in size. Early menarche, that is, the first period at a very early age (before the age of 10), increases the risk of the appearance of fibroids. While late menarche (after 16 years) is a protective factor. The amount of estrogen and its uterine receptors is determined. increased in women with fibroids. Some diseases related to sex hormones, such as polycystic ovary syndrome, endometrial hyperplasia, and infertility problems, are more common in women who have fibroids.

  Uterine fibroids, also known as uterine leiomyomas, fibromyoma or fibroids, are benign smooth muscle tumors of the uterus, part of the female reproductive system. The exact cause of uterine fibroids is unclear. However, fibroids run in families and appear to be partly determined by hormone levels. Risk factors include obesity and eating red meat. […] Genetic and hereditary causes are being considered and several epidemiologic findings indicate considerable genetic influence especially for early onset cases. First degree relatives have a 2.5-fold risk, and nearly 6-fold risk when considering early onset cases. […] The current working hypothesis is that genetic predispositions, prenatal hormone exposure and the effects of hormones, growth factors and xenoestrogens cause fibroid growth. Known risk factors are African descent, obesity, polycystic ovary syndrome, diabetes, hypertension, and never having given birth.

  More research is needed into the etiology of uterine fibroids, including studies that clarify the role of estrogen and progesterone and that identify risk factors, according to a literature review led by a School of Public Health researcher. […] According to Wise and Laughlin-Tommaso, studies have found that rates of fibroids tend to increase with age through the reproductive years and decline after menopause. […] Greater research is needed about why they grow and how to prevent them, says Wise. […] Past studies have indicated that fibroid risk increases with earlier onset of menarche and decreases among women who have given birth (particularly a recent birth). […] Wise and Laughlin-Tommaso say that while estrogen and progesterone are almost certainly involved in fibroid growth, the mechanisms through which they act are not well understood.
