Breast Pain: Why Do My Boobs Hurt?
From a dull ache to a sharp stab, breasts hurt in a hundred different ways for a hundred different reasons. For many women, those myriad aches and stabs are the results of normal, healthy hormone fluctuations related to their menstrual cycles.
“Pain is most common during that period of a woman’s cycle just before she menstruates, when hormones like estrogen and progesterone peak,” says Karthik Ghosh, MD, director of the breast clinic at Mayo Clinic in Rochester, Minnesota.
With the onset of menstruation, levels of those hormones drop off, Ghosh says. For that reason, breast pain or tenderness tends to subside as soon as a woman starts her period. Because oral contraceptives iron out those hormonal peaks and valleys, women on birth control often don’t experience this monthly ebb and flow of aching. (But when women first start a contraceptive like the pill, some pain is common.)
Many women also experience cysts, which result when pockets of fluid form within the ducts of the breast. These cysts can sometimes be painful, says Dr. Susan Harvey, director of the Johns Hopkins Breast Imaging Section.
Young women in puberty, pregnant women and older women nearing menopause may all experience breast pain due to hormone fluctuations, says Dr. Bonmyong Lee, Harvey’s colleague and an assistant professor of radiology at Johns Hopkins. Particularly during the early stages of menopause, women who may have never had pain or cysts may suddenly start to experience both, Lee says.
Pain can also be caused by a common type of inflammation, called costochondritus, which affects the place where a woman’s ribs and sternum come together. Even an unsupportive brassiere can allow the breasts to pull on the chest wall, leading to pain, Ghosh says.
One condition that tends not to cause pain is cancer. For women who may notice a lump that is sensitive or painful, it’s more likely a benign cyst, Ghosh says. Still, she recommends seeing a doctor if you find a lump, painful or otherwise.
There are several less common or unproven causes of breast pain, from infection to caffeine consumption. So how can you determine whether to worry or brush it off? If the pain is concentrated in one part of your breast and doesn’t subside after a few weeks, see someone, Harvey says. You should also visit a doctor if your skin is flushed or red, which may be a sign of an infection.
“There’s no golden rule when it comes to identifying specific types of breast pain,” Ghosh says. “If it worries you or seems out of the ordinary, see a doctor.”
