What the evidence says
Up to 70% of women experience breast pain, and pain that swells and settles with the cycle is hormonal and normal, usually in both breasts and worst before a period. Breast pain alone, with nothing else, is rarely a sign of cancer.
Guidance and the evidence behind it: cyclical, usually bilateral pain is hormonal and benign, and breast pain by itself is unlikely to be a symptom of cancer. In a study of 10,830 women referred to a breast diagnostic clinic, cancer was found in 0.4% of those referred with breast pain, against about 5% in each of the other groups. What needs looking at promptly, without a cycle's wait: a new lump; skin changes such as dimpling; a change in breast shape; or nipple discharge, especially if it is bloody or comes from one side. Pain that keeps going or is not eased by simple painkillers is also worth a non-urgent appointment. For pain that is simply cyclical and sore, a well-fitted bra and simple pain relief (tablets or a painkilling gel) are the usual first steps.
What this does not show
'Rarely cancer' comes with its boundary, and the boundary is the list: a new lump, skin changes such as dimpling, a change in breast shape, or nipple discharge, especially if it is bloody or comes from one side. Those get seen promptly, with no cycle's wait. The 70% figure is lifetime experience across women generally, not a statement about your breasts or your risk. Cyclical pain needs a cycle to read it against. If yours are irregular, the pattern is harder to see, so go by the list, and by pain that keeps going or is not eased by simple painkillers, rather than by timing. The well-fitted bra is standard advice; it is not known whether it reduces breast pain, so it is a comfort step, not a treatment.
