Why do your breasts get bigger before your period?
Many women may notice that their breasts become larger just before a week of menses, whereas others may not experience such symptoms. Breast swelling and tenderness occur due to a surge in hormones during the menstrual cycle. The estrogen that your body makes in the initial period of the menstrual cycle peaks just before the mid-cycle. As a result, the breast duct grows. The progesterone level peaks near the 21st day of a 28-day cycle. This results in the growth of the milk glands of the breast. Breast swelling may also be associated with
- Premenstrual syndrome (PMS)
- Fibrocystic breast disease (noncancerous changes giving the breasts a lumpy texture)
Breast swelling and tenderness may occur to some extent in nearly all women. Symptoms may be severe in many women during their childbearing years. Symptoms may be mild in women taking birth control pills. Some of the risk factors that may increase the chances of swelling or tenderness include
These changes seem to resolve once the menses arrives due to a decline in progesterone levels.
What breast changes happen at puberty?
When a young woman hits puberty, the first noticeable signs of breast development begin. When the ovaries start to make and release estrogen, fat in the connective tissue starts to collect. As a result, the breasts enlarge and the duct system also starts to grow. The female breast developmental stages are described below.
|Female breast developmental stages||Description|
|Stage 1||Preteen. Only the tip of the nipple is raised.|
|Stage 2||Buds appear and the breast and nipple are raised. The areola (the dark area of skin around the nipple) gets larger.|
|Stage 3||Breasts are slightly larger with glandular breast tissue present.|
|Stage 4||The areola and nipple become raised and form a second mound above the rest of the breast.|
|Stage 5||Mature adult breast. The breast becomes rounded and only the nipple is raised.|

Breast AnatomyThe breast, or mammary gland is made up of lobules, milk producing glands, and a system of ducts to transport milk. Both males and females have breasts. Abnormal enlargement of breasts in men is referred to as gynecomastia. In women, during pregnancy the breasts grow larger and produce milk. Common medical conditions that affect the breasts include breast cancer, breast lumps, fibrocystic changes and cysts, mastitis, and benign tumors (fibroadenomas).

Women with the condition often have fewer problems after menopause (postmenopause).

Natural and home remedies to help relieve breast pain include NSAIDs like aspiring, Aleve, and Advil. Prescription medication also may help relieve symptoms of fibrocystic breasts.
Menstruation (Menstrual Cycle)Menstruation (menstrual cycle) is also referred to as a "period." When a woman menstruates, the lining of the uterus is shed.
