肌瘤 are round growths that develop in the uterus. They are almost always benign, or non-cancerous. 肌瘤 range in size from as small as a pea to as large as a melon. They are also called leiomyomas or myomas.
肌瘤 are very common, affecting an estimated 20 to 50 percent of all women. They are most likely to affect women in their 30s and 40s, and for reasons we don't understand, occur more frequently in African-Americans. Many women with fibroids have family members who also have them.
Some fibroids grow steadily during the reproductive years, while others stay the same size for many years. All fibroids should stop growing after menopause. If your fibroids grow after menopause, you should consult your doctor.
Usually, fibroids cause no symptoms and don't require treatment. But if symptoms occur, you should seek medical attention.
Types of 肌瘤
肌瘤 can grow in different parts of the uterus:
- Pedunculated fibroids are attached to the uterine wall by stalks.
- Subserosal fibroids extend outward from the uterine wall.
- Submucosal fibroids expand from the uterine wall into the uterine cavity.
- Intramural fibroids develop within the uterine wall.
Different types of fibroids are associated with different symptoms. For example, submucosal fibroids typically cause heavy periods. 与此形成鲜明对比的是, subserosal fibroids are more likely to push against the bladder, causing frequent urination.
Causes of 肌瘤
利来登录 and medical researchers do not know what causes fibroids to develop. There is evidence that the female hormones, estrogen and progesterone, can make them grow. During pregnancy, when the hormone levels are high, fibroids tend to increase in size. After menopause, when the hormone levels are low, fibroids stop growing and may become smaller.
