Adenomyosis involves what kind of bodily change?

Adenomyosis is characterized by the abnormal growth of endometrial tissue within the muscular wall of the uterus. Specifically, this condition occurs when the endometrial tissue, which normally lines the inside of the uterus, begins to grow into the uterine muscle (myometrium). This can lead to a variety of symptoms, including heavy menstrual bleeding, severe cramping, and pelvic pain.

The growth of this tissue within the uterine muscle can cause significant swelling and enlargement of the uterus, which may contribute to the discomfort and other complications associated with the condition. Understanding this abnormal growth is crucial for the diagnosis and management of adenomyosis.

In contrast, the other responses indicate unrelated conditions: fluid-filled sacs in the ovaries pertain to ovarian cysts, hyperplasia of prostate cells relates to prostate conditions in men, and an increased risk of lung infection does not have any relevance to adenomyosis. Thus, the focus on the abnormal growth of endometrial tissue accurately describes the primary change that occurs in adenomyosis.
