User avatar Hello,

There are many possible causes for breast or axillary pain. These can be broken down into causes related to menstruation (cyclical) or noncyclical pain. Although many women with pain in one or both breasts understandably fear breast cancer, breast pain is NOT a common symptom of cancer.

Common causes of cyclical breast pain include:

Some degree of breast tenderness is normal, caused by hormonal fluctuations. They can be a manifestation of premenstrual syndrome (PMS). Fibrocystic breast tissue is a common condition. It involves breast lumps and bumps throughout the breast tissue that tend to be more tender just before your menstrual period.

Noncyclical breast pain can be due to hormonal changes other than those of the menstrual cycle. This includes pregnancy (tends to be more common during the first trimester and pregnancy at a young age); puberty (in both girls and boys); breast feeding; approach of menopause (once your menstrual periods have stopped completely, breast tenderness often goes away unless you are taking hormone replacement therapy) and also soon after childbirth, the breasts may become engorged with milk.

Mastitis from a blocked and infected milk duct, usually associated with breastfeeding; alcoholism with liver damage and injury/ trauma to the breast. Certain medications may also cause breast pain, including digitalis preparations, aldomet, aldactone and other potassium-sparing diuretics, anadrol, and chlorpromazine. Shingles can lead to pain felt in the breast if the painful blistering rash appears on the skin over one of your breasts.

You may be feeling the inflammed axillary tail of the breast. Its best to have it examined.

Best regards.
