Key takeaways
- Breast pain, or mastalgia, is very common. Possible causes of breast pain include hormonal changes, an incorrect bra fit, and infections. Breast pain is not usually a sign of breast cancer, but it can be.
- Breast pain management will depend on its cause, but painkillers and self-management techniques, such as wearing a comfortable supportive bra and getting regular exercise, can often help in mild instances.
- People should consider speaking with a doctor before trying any self-management techniques for breast pain.
Pain in the breast affects approximately
Breast pain may have an obvious external cause, such as sports injuries and latching irritation during chestfeeding. However, the cause may not always be as clear as this.
The use of binary terms such as “male” and “female” or “men” and “women” in this article reflects the language of the sources we’ve used. Unless otherwise noted, it’s unclear whether the research we reference included participants with expansive gender identities.
Cyclic pain, which is related to the menstrual cycle, and noncyclic pain have some key differences. The following table compares and contrasts the two types of pain:
| Cyclic pain | Noncyclic pain |
|---|---|
| varies with hormones in the menstrual cycle | does not vary with the menstrual cycle |
| common among younger women | more common after menopause |
| generally affects both breasts equally | tends to affect one or more localized areas of one breast |
| may occur alongside tenderness, swelling, or lumpiness | pain often feels sharp and burning |
If a person has cyclic pain, but the pain is worse in one breast than the other, hormones may not be the only cause.
Tender or swollen breasts are usually related to the hormonal changes before a period, pregnancy, or menopause, according to the United Kingdom’s National Health Service (NHS). This type of breast pain usually causes tenderness in both breasts, and it may extend to the armpit.
When breast pain is related to the menstrual cycle, it is known as cyclic breast pain. Cyclic breast pain can be part of a set of symptoms that occur before a period, known as premenstrual syndrome (PMS), or it may occur on its own.
PMS is temporary, but people can treat the symptoms by taking over-the-counter (OTC) pain relievers, wearing a comfortable and supportive bra, and using gentle heat to soothe the pain.
Bras can cause breast pain if they are too tight or they contain an underwire that digs into the skin or breast tissue.
People can get a bra fitting for free at many department stores to find the right size. They may wish to purchase non-wired, supportive, and comfortable bras if they experience soreness before their period.
Supportive bras can also help when exercising. According to a 2025 article,
Fibrocystic breast changes are harmless but potentially uncomfortable symptoms that cause the breasts to feel lumpy or otherwise different in texture due to hormonal fluctuations. Fibrocystic breast disease is the
The symptoms may include:
- breasts that feel firmer or thicker than usual
- tenderness
- lumps or cysts
- sensitive nipples
The treatment or management of fibrocystic breasts may involve:
- taking OTC pain medication
- applying cool or warm compresses
- avoiding a large intake of salt, caffeine, or fat
- wearing a supportive but comfortable bra
- starting or stopping birth control pills
- draining large cysts
If fibrocystic breast changes may be related to a new contraceptive, it is important to speak with a doctor before making any changes to the dosage.
Mastitis is the term for inflammation or swelling in the breasts. The
The treatment for a bacterial infection is antibiotics. A person who is chestfeeding will also need to empty the breasts of milk. If an abscess is present, doctors will drain the pus surgically or remove it with a needle.
The NHS notes that some medications, like birth control pills and certain contraceptives, can contribute to the development of breast pain.
People with breast pain should speak with a doctor to find out whether any of their medications could be causing their symptoms.
Both surgery and radiation therapy for breast cancer can cause scar tissue formation. This can result in numbness, pain, and changes in breast texture and appearance.
Treatment options include:
- physical therapy
- surgical removal of scar tissue
- use of creams and ointments to lessen the appearance
Breast pain can originate from outside the breast rather than within it. For example, the NHS notes that sprains or injuries in the back, neck, or shoulder might cause pain that a person feels in the breast.
When people perceive pain in a broader area than the site where it originates, this is known as referred pain. The treatment relies on finding the underlying problem.
Costochondritis is inflammation of the costal cartilage, which connects the ribs to the breastbone. The NHS notes that condition can cause sharp chest pain and tenderness, and it may have a gradual or sudden onset.
Treatment may include:
- avoiding activities that worsen the pain
- applying heat to the area
- OTC pain relievers
- corticosteroid injections
- undergoing transcutaneous electrical nerve stimulation (TENS), a procedure that applies an electric current to an area to reduce pain
A range of conditions can cause pain in the wall of the chest. Breast Cancer Now notes that this pain can sometimes feel as though it is coming from the breast, even though it is not.
The pain can vary in extent, ranging from one specific area to a wide area of the breast.
Possible causes include:
The treatment will vary based on the cause, but it may involve pain management and avoiding movements that worsen the pain until the root cause has improved.
Breast cysts are fluid-filled sacs. They are noncancerous, relatively soft, and more common in premenopausal women ages 30 to 50 years, according to BreastCancer.org. Some cysts do not produce symptoms, but others may cause pain and nipple discharge.
Unless the cysts are particularly large or painful, they do not need treatment. If treatment is necessary, it involves draining the fluid out with a needle.
Breast cancer occurs when cells in the breast mutate and begin growing uncontrollably. Pain in the breast is
- a lump in the breast
- pain in any part of the breast
- any nipple discharge — bloody, clear, or otherwise
- dimpling or irritation of breast skin
- pain and tenderness
- skin discoloration
- swelling

People can take
A person should consider speaking with a healthcare professional before trying self-care techniques to ensure they are appropriate. In certain circumstances, medical intervention may be necessary.
A 2016 study suggests that stress and anxiety can contribute to the onset and severity of breast pain. A 2021 observational study also found that breast pain is associated with a higher prevalence of stress, anxiety, and depression, potentially causing a cycle of symptoms.
Hormonal changes, mastitis, cancer, and fibrocystic breast changes can all cause tenderness in breast tissue. This tenderness may mean that breasts are painful to the touch.
It is important to seek medical assistance if breast pain:
- does not resolve with pain medication
- occurs regularly
- accompanies cancer symptoms such as skin changes, lump growths, or discharge
The NHS notes that breast pain in only one breast is not unusual and could be due to a range of possible causes, just like pain in both breasts.
There are multiple possible causes of breast pain or mastalgia. This symptom may be cyclic or noncyclic. If the pain is cyclic, it is related to the fluctuating hormones of the menstrual cycle.
Noncyclic breast pain can be due to PMS, fibrocystic breast changes, injuries and sprains, or inflammation around the ribs. Sometimes, cysts or infections are responsible for this symptom.
Although breast cancer is not usually a cause of breast pain, anyone with this symptom should consult a doctor to rule out this condition.
