The short explanation
Breast pain before periods often changes in the forties. In the years before menopause, hormone levels can swing more unevenly from cycle to cycle, and many women notice more breast tenderness, swelling or lumpiness at this time. It is very common and usually settles after menopause. Because this is also the age when breast screening often starts, it is a good time to have a doctor examine you and talk about a mammogram.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Cyclical pain usually affects both breasts and eases once a period starts. Pain in one spot, in one breast, that does not follow your cycle is more worth examining.
- Caffeine and stress are sometimes blamed; evidence is mixed, but some women find cutting back helps. A well-fitted supportive bra often helps.
- Hormone treatment, including some contraception, can change breast tenderness too.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether your pain is cyclical or due to something else. An examination and your history help decide that.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Does my pain fit the cyclical pattern?
- Is it time for me to start breast screening?
- Are my periods changing in a way that suggests perimenopause?
- What can I do to ease the pain?
