Medicines for Breast pain

What it is

Breast pain (mastalgia) is very common and is usually not a sign of breast cancer — most breast pain has a harmless cause. It is often described in two patterns. "Cyclical" breast pain is linked to the menstrual cycle, tends to affect both breasts, is often heavier or aching, and worsens in the days before a period, easing when it starts — this is related to normal hormonal changes and is very common. "Non-cyclical" pain is not linked to periods and may come from the breast itself or from nearby structures (such as the chest wall or muscles), and can be one-sided or localised. Causes include hormonal changes, certain medicines (including some contraceptives and HRT), breast cysts, large breasts, ill-fitting bras, and sometimes strain of the chest wall. While breast pain alone is rarely due to cancer, any new lump, or other worrying changes alongside pain, should be assessed.

How it is treated

Reassurance is a key part of care, as understanding that breast pain is common and usually harmless helps a great deal. For cyclical pain, simple measures often help: wearing a well-fitting, supportive bra (including for exercise and sometimes at night), simple pain relief, and keeping a pain diary to understand the pattern; reviewing any contributing medicine (such as certain contraceptives) with a doctor may help. For non-cyclical pain, treating the source helps — for example if it is coming from the chest wall or a cyst. Most breast pain improves over time. If the pain is persistent, severe, affecting daily life, or not settling with simple measures, a doctor can assess it and consider further options. Importantly, any breast pain that comes with a new lump, skin or nipple changes, or is focused in one area and persistent, is assessed to exclude other causes. The reassuring message is that breast pain is common, usually harmless, and often improves with simple measures — but new changes are always worth checking.
