The most common cause of breast discomfort is from the effects of hormones on breast tissue from the female menstrual period. Many women experience mild monthly breast pain in conjunction with their periods (menses). For some women, however, the pain can be more severe. This premenstrual breast pain is referred to as cyclic breast discomfort. The exact cause of cyclic breast discomfort has not been determined.
Much less common causes of breast pain include benign growths (tumors) in the breasts (including cysts), breast cancer, and certain medications. It should be noted that breast cancers are often painless and can be detected by manual examination, mammogram, or ultrasound of the breast. Breast pain is called mastodynia, mastalgia, or mammalgia by physicians.

Breast Cancer
Breast cancer is an invasive tumor that develops in the mammary gland. Breast cancer is detected via mammograms, breast self-examination (BSE), biopsy, and specialized testing on breast cancer tissue. Treatment of breast cancer may involve surgery, radiation, hormone therapy, chemotherapy, and targeted therapy. Breast cancer risk may be lowered by managing controllable risk factors. What you should know about breast cancer Breast cancer is the most common cancer among American women. One in every eight women in the United States develops breast cancer. There are many types of breast cancer that differ in their capability of spreading (metastasize) to other body tissues. The causes of breast cancer are unknown, although medical professionals have identified a number of risk factors. There are 11 common types of breast cancer and 4 uncommon types of breast cancer. Breast cancer early signs and symptoms include a lump in the breast or armpit, bloody nipple discharge, inverted nipple, orange-peel texture or dimpling of the breast's skin (peau d'orange), breast pain or sore nipple, swollen lymph nodes in the neck or armpit, and a change in the size or shape of the breast or nipple. Breast cancer can also be symptom free, which makes following national screening recommendations an important practice. Breast cancer is diagnosed during a physical exam, by a self-exam of the breasts, mammography, ultrasound testing, and biopsy. Treatment of breast cancer depends on the type of cancer and its stage (0-IV) and may involve surgery, radiation, or chemotherapy.
