Is a uterine fibroid the size of an egg yolk considered serious?
Generally, an egg-yolk-sized uterine fibroid is not considered serious if it is asymptomatic, grows slowly, and does not affect fertility. However, it may be more serious if accompanied by symptoms such as bleeding or abdominal pain, if it grows rapidly, or if it affects fertility. If in doubt, it is recommended to seek medical advice early. Specific analysis is as follows:

If an egg-yolk-sized uterine fibroid is located in the serosal layer of the uterus (outer surface) without compressing surrounding organs, causing no menstrual irregularities or abdominal pain, and ultrasound follow-ups show slow growth with no impact on daily life or fertility, the condition is usually not serious and only requires regular monitoring.
However, if the fibroid is located in the endometrial layer (inside the uterine cavity) or within the muscular wall of the uterus, leading to heavy menstrual bleeding, prolonged periods, or even anemia; or if it grows rapidly with a noticeable increase in size over a short period; or if it compresses the bladder or rectum causing urinary or bowel dysfunction, or interferes with conception, the condition may be more serious and require timely medical intervention.
After detection of an egg-yolk-sized uterine fibroid, regular ultrasound follow-ups should be conducted as directed by a physician to monitor changes in the fibroid. If symptoms worsen or any abnormalities occur, prompt medical consultation is necessary to develop an appropriate management plan based on the doctor’s recommendations.
