Breast discharge is the spontaneous flow of fluid from the nipple at any time other than during nursing. Breast discharge can be caused by a wide range of disorders, including
- breast cancer,
- breast ectasia, and
- breast infection.
- Sometimes it's possible to feel breast cancer as a breast lump. The breast lump may or may not be painful or tender.
- Breast duct malformation (duct ectasia) can lead to breast discharge.
- Mastitis is the medical term for a breast infection, and mastodynia is the medical term for breast pain. Another name for the nipple is areola.
A physician should evaluate persisting breast discharge (nipple discharge).

Causes of Breast Discharge
The breast, or mammary gland is made up of lobules, milk producing glands, and a system of ducts to transport milk. Both males and females have breasts. Abnormal enlargement of breasts in men is referred to as gynecomastia. In women, during pregnancy the breasts grow larger and produce milk. Common medical conditions that affect the breasts include breast cancer, breast lumps, fibrocystic changes and cysts, mastitis, and benign tumors (fibroadenomas).
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.
Breast Cancer Facts
Breast cancer is the most common non-skin cancer of American women, but it can also occur in men. Every year in the U.S., there are over 266,000 new diagnoses of breast cancer. A woman has a risk of one in eight for developing breast cancer at some point during her lifetime.
Breast Lumps (in Women)
Breast lumps in women can have a variety of causes such as breast inflammation, infection, injuries, cancer, and non-cancerous growths. Breast lumps in women are diagnosed with physical exam, mammogram, ultrasound, MRI, and biopsy. Treatment of breast lumps in women depend on the cause.
Breastfeeding: Common Breastfeeding Challenges
Breastfeeding an infant can cause common challenges both for the mother an infant. Some challenges include sore nipples, low milk supply, oversupply of milk, engorgement, plugged ducts, breast infection, fungal infections, nursing strike, inverted, flat, or very large nipples, breastfeeding a baby with health problems, and breastfeeding in special situations. Tips and helpful information can inform mothers how to manage and handles these challenges while continuing to breastfeed her baby.
Can Fibroadenomas Turn Into Breast Cancer?
A fibroadenoma is the most common type of benign, non-cancerous lump of the breast. Although it is rare, complex fibroadenomas and phyllodes tumors have a chance to develop into malignant breast cancer.
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
Inflammatory Breast Cancer
Inflammatory breast cancer is an accelerated form of breast cancer that is not usually detected by mammogram or ultrasound. Symptoms of inflammatory breast cancer include pain in the breast, skin change in the breast area, bruise on the breast,sudden swelling of the breast, nipple retraction or discharge, and swelling of the lymph nodes.
Kidney (Renal) Failure
Kidney failure can occur from an acute event or a chronic condition or disease. Prerenal kidney failure is caused by blood loss, dehydration, or medication. Some of the renal causes of kidney failure include sepsis, medications, rhabdomyolysis, multiple myeloma, and acute glomerulonephritis. Post renal causes of kidney failure include bladder obstruction, prostate problems, tumors, or kidney stones.Treatment options included diet, medications, or dialysis.
Male Breast Cancer
Male breast cancer accounts for 1% of all breast cancers, and most cases are found in men between the ages of 60 and 70. A man's risk of developing breast cancer is one in 1,000. Signs and symptoms include a firm mass located below the nipple and skin changes around the nipple, including puckering, redness or scaling, retraction and ulceration of the nipple. Treatment depends upon staging and the health of the patient.
Paget Disease of the Breast (Paget's Disease of the Nipple)
Paget's disease is a rare form of cancer that forms in or around the nipple and frequently coexists with breast cancer. The exact cause of Paget's disease is unknown. Symptoms and signs include redness, scaling, and flaking of the nipple skin. A biopsy and imaging studies are needed to diagnose the disease. Treatment may include surgery, radiation, and adjuvant therapy.
Pregnancy (Week by Week, Trimesters)
Signs and symptoms of pregnancy vary by stage (trimester). The earliest pregnancy symptom is typically a missed period, but others include breast swelling and tenderness, nausea and sometimes vomiting, fatigue, and bloating. Second trimester symptoms include backache, weight gain, itching, and possible stretch marks. Third trimester symptoms are additional weight gain, heartburn, hemorrhoids, swelling of the ankles, fingers, and face, breast tenderness, and trouble sleeping. Eating a healthy diet, getting a moderate amount of exercise, also are recommended for a healthy pregnancy. Information about the week by week growth of your baby in the womb are provided.
Prolactinoma (Pituitary Tumor)
Prolactinoma is an adenoma (benign tumor) of the pituitary gland. Causes of many prolactinomas are unknown. Symptoms in women include: changes in menstruation and infertility, decreased libido, or painful intercourse due to vaginal dryness. The most common symptom in men is impotence (erectile dysfunction). Treatments for prolactinomas include medication and surgery.
Triple-Negative Breast Cancer
Triple-negative breast cancer is more common in Hispanic and African-American women. Signs and symptoms include a lump in the armpit or breast, nipple discharge and inversion, and changes in the breast's skin. Treatment may incorporate surgery, chemotherapy, and radiation therapy.
