Why do breasts enlarge, reasons for swelling and enlargement of breasts before menstruation (menstruation)?

The reasons why a woman's mammary glands enlarge before menstruation are very varied, but in most cases such symptoms do not indicate the development of any health problems. The female body is designed in such a way that, under the influence of hormonal changes characteristic of different phases of the menstrual cycle, it undergoes constant physiological transformations. So, before menstruation, before the onset of menstruation, not only discomfort and pain in the chest may appear, but the breasts may increase in size, and pain in the nipple area may be accompanied by an increase in their halos. Such changes are influenced by prolactin, progesterone and estrogen. These hormones are produced over a significant period of a woman’s life, and at each stage of the body’s development they have a different concentration rate.

It is important for women to remember that if before menstruation the breasts have enlarged, but after their end they have not acquired their usual size, then there is a reason to consult a doctor, especially in the case when breast enlargement is accompanied by pain in the breast.

Breast enlargement in women during the premenstrual period is considered normal, even swelling and pain in the breast area before the onset of menstruation can be normal if such symptoms and signs of PMS are repeated every month and the chest pain is not severe. These days there is an increase in tissue and swelling of the mammary glands. An additional factor contributing to breast enlargement during menstruation is the retention of fluid by body tissues during the luteal phase of the cycle. Thus, the breasts become a little larger and gain increased sensitivity.

Water retention in the body before menstruation helps the body comfortably adjust to the proliferation necessary to create and maintain favorable conditions for the egg in the event of its fertilization. During each menstrual cycle, a woman’s hormonal system prepares the body for conception and bearing offspring. Therefore, breast enlargement, swelling in this area, discomfort and even pain in the nipples or pain in the chest area are a natural sign of imminent menstruation. Significant breast enlargement during menstruation may indicate pregnancy. Each case must be considered individually, since the hormonal background of each individual woman is unique.

When you need to urgently visit a doctor

  • unusual lumps are felt in the chest;
  • you cannot palpate your breasts yourself;
  • age over 40 years and the woman has never been to a mammologist;
  • brown, unusual discharge from the nipple;
  • inconvenience and pain are such that a woman cannot lead a normal life.

Enlargement of the mammary glands before menstruation is a normal natural process, but there are exceptions to the rule when such signs indicate the presence of a pathology that can lead to serious consequences.

Therefore, dear women, listen to your body, especially after menstruation. If your breasts still become swollen and tender, see your doctor.

The influence of hormones on the menstrual cycle

The reasons for breast enlargement before menstruation can be explained by natural physiological reasons that appear as a result of hormonal changes, which in turn are a natural process of changes in the female body before the onset of menstruation. Therefore, in most cases, breast enlargement and swelling, nipple pain and pain in the chest area before menstruation are absolutely natural signs and symptoms of PMS, premenstrual syndrome. After ovulation, the level of progesterone in a woman’s blood increases. Its amount does not decrease until the body understands that fertilization of the egg has not occurred this time. Once the lack of conception is accepted by the body, progesterone levels drop sharply. Before menstruation, progesterone and estrogen have the lowest concentration levels in a woman’s blood.

Breast tenderness coincides with the maximum concentration of progesterone.

This phenomenon is one of the components of premenstrual syndrome, when before menstruation (menstruation) the breasts enlarge and their shape changes.

However, if some women suffer from it every cycle, others can only guess about its existence. Women who do not experience symptoms of PMS may also experience breast enlargement before their period. For them, the cause of this phenomenon is constant stress and overwork, the influence on the activity of the hormonal system of medications, especially hormonal contraceptives, wearing tight underwear that interferes with blood circulation, addiction to foods that allow fluid to be retained in the tissues or accompanying swelling, for example, salty and fatty dishes or with coffee.

How does the mammary gland work?

The main functional unit of glandular tissue is the lobule, which consists of tubular glands and excretory ducts. The lobular ducts merge to form the lobular ducts. Thus, the mammary gland is something like a bunch of grapes, where the grapes are segments and the branches are ducts. Small ducts merge into larger ones - lobar ducts, and they, in turn, follow to the nipple.

Directly behind the nipple, the ducts widen to form lacteal sinuses , which collect milk. The ducts then open on the nipple in the form of several holes. Knowing this feature, you can understand how to properly express your breasts manually during lactation: by pressing your fingers on the areola area (expressing the contents of the sinuses), but without exerting any force on the base of the breast.

The nipple is surrounded by pigmented skin (areola). During pregnancy, “tubercles” become clearly visible on the skin of the areola - these are the Montgomery glands. They are modified sebaceous glands that protect the nipple from drying out and infections during feeding.

It is also important to know the routes of lymph outflow from different parts of the mammary gland. Lymph drainage mostly occurs in the axillary lymph nodes. From the internal sections (those located closer to the middle of the chest), lymph flows into the sub- and supraclavicular lymph nodes (the latter can be felt above the collarbone) and into the lymph nodes located in the chest cavity (parasternal).

Rarely, with breast cancer, when the above groups of regional lymph nodes are affected, tumor metastases with lymph flow can enter the inguinal, axillary, sub- and supraclavicular, parasternal lymph nodes on the side opposite to the lesion.

When is breast enlargement before menstruation dangerous or a sign of pathology?

There are also dangerous factors that contribute to breast enlargement. Breast augmentation before menstrual periods deserves attention if, after their completion, they have not returned to their normal size, and the owner feels pain and lumps. Such symptoms can signal pathologies, including gynecological diseases, thrombophlebitis, benign and malignant tumor processes, disorders of the thyroid gland and adrenal glands, cysts, abscesses and nodes, as well as inflammatory processes in the chest.

At any stage of the menstrual cycle, a woman should pay attention to changes in the functioning of her body, and if deviations are observed, in particular, manifested in pain or the appearance of lumps in the mammary glands, uncharacteristic enlargement, immediately consult a mammologist or gynecologist for diagnosis possible violations.

What diseases can be diagnosed

Additional pathological signs may indicate the presence of diseases. In this case, there is foreign discharge from the chest. The mammary gland is deformed. The disorder may affect only one breast.

The listed symptoms require contacting a doctor. A woman may be diagnosed with mastitis. Usually the condition appears in girls who refuse breastfeeding. The chest swells and becomes hot. There is intense pain syndrome.

Mastitis can affect either one mammary gland or two at once. The breast becomes hard to the touch. Sometimes you can't touch her.

Uterine fibroids can also cause pain. This neoplasm is benign. In the initial stages, the signs present can easily be confused with pregnancy. When sick, the menstrual cycle is disrupted. Menstruation either disappears completely or, on the contrary, continues constantly.

One of the possible pathologies in this case is an ovarian cyst.

A woman may also be diagnosed with ovarian cysts. In this case, pain appears in the lower part of the abdominal cavity. The pain gradually intensifies. Sensitivity also affects the breast.

How do girls' breasts grow during puberty?

The rudiments of the mammary glands appear around the sixth week of intrauterine development. Before puberty, the breasts are in a “dormant” state: the lobules are not yet formed, only the main ducts are present. During puberty, under the influence of estrogens, breast growth and development : the ducts begin to branch, lobules form.

At the beginning of puberty, girls may notice the appearance of dense, painful “lumps” behind the nipple. This is the beginning of breast formation. Often these “lumps” appear out of sync and make the girl and parents worry. A visit to a normal doctor puts everything in its place.

Gradually, with the formation of a stable regular menstrual cycle, the breasts acquire a mature structure: the lobules and ducts are well formed and ready for their main function.
