Causes of breast soreness in women
Is this common?
Yes, breast soreness is common. For some women, it is only on one breast or part of one breast, for other women it is both breasts. It can be aching, stabbing, throbbing, dull or sharp. It can be constant or intermittent. It can range from mild to severe.
What are the causes?
- Non-pregnant, premenopausal
Lots of women have breast soreness due to hormonal fluctuations through the menstrual cycle. In the few days to the week prior to the period, the hormonal rise in oestrogen causes glands to swell causing the breast tenderness. This breast tenderness is often bilateral. Often, once the period comes, the soreness subsides. By the end of the period, the breast soreness is often resolved. This swelling of the breast can often cause lumpiness. If a women is able to feel a lump or is unsure about lumpiness in her breast, she needs to have a clinical examination with her doctor.
Hormonal breast soreness is normal, but often not severe. If it is limiting daily function or lasts for longer, then it should be reviewed by a medical practitioner and further investigations may be warranted.
In the first trimester of pregnancy, breast soreness is very common. In fact, it is often the first sign that the woman is pregnant. This is due to the sudden surge in hormones to accommodate the growing embryo.
- Breast cysts
Breast cysts can often become sore with possible lumps, able to be felt by the woman, especially during the time the hormones are rising. They can become more sensitive, increase in size and make the breast feel lumpy. To confirm the presence of breast cysts, an ultrasound can be organized by your doctor.
