Uterine tumor bleeding is usually dark red in color, similar to normal menstrual bleeding, and it is sometimes difficult to tell if it is caused by menstruation or fibroid bleeding. If the fibroids are large, the color will turn bright red and the bleeding will be heavy, which may lead to anemia or shock when the bleeding is heavy. Therefore, it is best to seek medical attention in a timely manner to avoid serious cases of fibroid bleeding. It is recommended to have a timely diagnosis and treatment after the appearance of fibroids, and it is better not to distinguish whether it is a fibroid bleeding or other bleeding by its color.
