Estradiol

Estradiol is the most abundant of the estrogens, the group of steroids responsible for the development of sex organs and secondary sexual characteristics in women. Estradiol is involved in regulating the menstrual cycle and helps maintain pregnancy. Estradiol is also important for bone growth and metabolism in both men and women.

Levels of estradiol must be interpreted in light of the clinical situation (i.e. age, pregnancy, stage of the menstrual cycle, hyperthyroidism, cirrhosis, etc.) and associated hormone test results (FSH, LH, progesterone, etc.). In women and young girls, abnormally high levels of estradiol are found in early-onset puberty, ovarian and adrenal tumours, and following ovulation stimulation. In men, high levels of estradiol can be associated with gynecomastia (enlarged breasts), testicular and adrenal tumours, and delayed puberty. Low levels in women are normal during menopause but can also be associated with pituitary or ovarian dysfunction (polycystic ovaries), genetic problems (Turner’s syndrome), anorexia nervosa or extreme endurance exercise.

Breast cancer

Breast cancer: This is a malignant tumour made up of many cancerous cells. It should be noted that breast cancer is not the most common cause of breast pain, as patients of this disease are often asymptomatic.
