Uterine fibroid bleeding is not cancer. When women have fibroids, those growing in the myometrium are more common, which will affect the contraction of the uterus and lead to the opening of blood vessels, and women will experience prolonged periods, increased menstrual flow, and even irregular menstruation. Fibroids are hormone-dependent benign tumors. Smaller fibroids can be temporarily observed, or if they grow larger or have increased menstrual flow or bleeding that is not well treated with hemostatic drugs, they can be treated with surgery. However, in rare cases, women with fibroids and thick endometrium may also have fibroids combined with endometrial cancer bleeding. When a woman is suffering from fibroids bleeding a lot, it is better to do diagnostic scraping as well to clarify the diagnosis.
