Breast pain and the menstrual cycle

Breast pain is a very common symptom and usually does not imply the presence of disease. How is it related to the menstrual cycle? In this opportunity, we want to detail it.

Mastalgia is defined as breast pain, that is, breast pain. Unfortunately, many women experience it, to a greater extent, during PMS. Menstruation is influenced by a multitude of factors, with a relationship between breast pain and the menstrual cycle.

Often, it is common in young women and, with the onset of menopause, disappears. Around 70% of women have experienced it sometime in life. Learn more about this typical symptom during menstruation.

What is the relationship between breast pain and the menstrual cycle?

It usually appears during the second half of the cycle (after ovulation, known as the luteal phase) and disappears at the beginning of the period. In this period hormonal changes like the following take place:

  • The estrogen usually peaks at ovulation. This is summarized in the growth of the mammary ducts.
  • Progesterone peaks a few days later (Day 21). This causes an enlarged breast lobule, which helps cells prepared for milk production to form.

To understand it better, the hormonal changes that occur during this phase cause inflammation, swelling, and enlargement of the breasts, which is painful on many occasions. Also, if pregnancy is carried out (by keeping progesterone high) they will continue to swell longer.

Biologically, the breasts have a greater number of receptors for these substances, which makes it a hormone-dependent gland. To a large extent, the breasts react more easily to hormones than the rest of the organs in the body.


  • Consume diets rich in fat.
  • Too much caffeine, theine, or chocolate.
  • Family history of pain during the cycle.
  • Certain medications (hormones, antidepressants, etc.).
  • Large breast size (increases weight-bearing and may be accompanied by back or neck pain).
  • Having breast pain does not have to be a sign of breast cancer. Only 10% of cases of malignant breast tumors cause mild pain.


Breast pain and the menstrual cycle (cyclical)

  • It affects young people.
  • As a general rule, it does not affect during or after menopause.
  • Homogeneous and bilateral distribution (that is, both breasts hurt and it extends throughout the mammary gland).
  • Swelling or inflammation.
  • Accumulation or retention of liquids in the breasts.
  • The slight increase in size.
  • Turgor (bulging and firm breasts).
  • Continuous pain (which can go from mild to severe) only during one stage of the cycle.
  • To the touch, small lumps or lumps are noticed throughout the breast.
  • Increased intensity of symptoms two weeks before menstruation.
  • The pain after the start of the period disappears.

Noncyclical breast pain

  • Continuous or intermittent pain, fixed at one point, described as burning, stabbing, or tearing.
  • Inflammation located at a point of the breast.
  • Symptoms do not vary over time or throughout a cycle.
  • It affects, to a greater extent, after menopause.
  • It is usually unilateral (only one breast hurts).

When to consult with a health professional?

  • Change in the shape, color, or appearance of the breast skin.
  • Secretions or fluid in the breasts.
  • Hormonal alterations.
  • New, unusual, or changing lumps or bumps on the breasts.
  • Age over 40 years without previous mammograms.
  • Pain that does not subside and increases in intensity.
  • Signs of infection (heat, redness, pus, etc.).
  • Pain that interferes with daily activity.

In short, breast pain is associated with the menstrual cycle and the hormonal changes that occur in it. Very rarely does it alert to a serious problem, but it is necessary to be alert, especially if the pain is prolonged and severe.
