The endometrium, the tissue that lines the inner wall of the uterus, plays a vital role in a woman's reproductive health. Subject to hormonal fluctuations, it can undergo cellular changes that sometimes reveal serious pathologies such as uterine cancer or uterine infection. To diagnose these conditions, doctors rely on a specific medical procedure: endometrial biopsy. By taking a sample of endometrial tissue, the cells are analyzed in detail and any abnormalities are detected.
