Sensitive or painful breasts result from changes in breast tissue. The glandular tissue in your breasts is highly responsive to hormones, which can make it feel tense, sensitive, or painful. Symptoms can occur in both breasts, one breast, or a specific part of a breast. Sometimes, the sensitivity is also noticeable in the armpit or the inner side of the arm.
During perimenopause, oestrogen and progesterone levels begin to fluctuate. Progesterone often decreases more rapidly than oestrogen, leading to a temporary relative excess of oestrogen. These hormonal changes affect the glandular tissue in the breasts and can intensify symptoms.
A benign change in the glandular tissue of the breast is called mastopathy. This condition can cause lumps or irregularities in the breast tissue. It is more common during phases of significant hormonal fluctuations.
As you approach menopause, oestrogen levels continue to decline. The glandular tissue in the breasts decreases and is gradually replaced by fatty tissue. This can lead to changes in the firmness, size, and shape of your breasts. For many women, pain and sensitivity diminish after menopause.
