Breast Lumps – Causes, Symptoms, Diagnosis, And Treatment


A breast lump is an abnormal growth or enlargement of tissue that develops within your breast. There are many types of breast lumps that vary in size, look, and feel. While most of the breast lumps are benign or noncancerous, some are malignant or cancerous. Here is brief description about causes, symptoms, diagnosis, and treatment of breast lumps.


While there are many causes of breast lumps, the following are a few major causes

  1. Abscesses: Sometimes painful abscesses are formed in the breast. These abscesses are caused by bacteria and are noncancerous. Reddening of breast skin and breast skin feeling solid or hot are signs of an abscess. Most of the breast-feeding women develop breast abscesses. Usually the abscesses are benign or noncancerous.
  2. Fibro-Cystic Breast Disease: Fibrocystic breast disease, also called fibroadenosis, is benign and noncancerous. This condition is not harmful or dangerous. This condition occurs when breast tissue fails to respond appropriately to the hormonal changes during the menstrual cycle.
  3. Intraductal Papilloma: Intraductal papillomas are small noncancerous tumors that form in the milk duct of the breast. These papillomas either appear as one large lump or as many small lumps. These lumps carry no known risk factors. Women in the age group of 35 to 55 are more likely to get these papillomas.
  4. Fibroadenoma of Breast: A fibroadenoma is a tumor in the breast that is benign or noncancerous. Fibroadenomas form due to abnormal response to the hormone estrogen. Sometimes fibroadenomas are too small to be felt, nontender, feel like marbles, and are moveable under the skin. Fibroadenomas are not life-threatening, but it is safe to get treatment.
  5. Mastitis: Mastitis is an infection of the breast tissue causing swelling, inflammation, and redness of the breast. This condition mostly occurs in breast-feeding women. Mastitis can also cause lumps in women who are not breast-feeding. If untreated, an abscess may form. Treatment with antibiotics is effective in curing mastitis.
  6. Lipoma: A lipoma is a benign growth that develops in the fat tissue of a breast. It doesn’t require any treatment as it is non cancerous, but sometimes doctors remove it surgically if it is too large and causing any symptoms.
  7. Fat necrosis: Lumps can form due to injury or trauma to the fatty tissue in your breast. These lumps are not harmful and normally heal and disappear over a period of time.
  8. Breast cancer: While majority of breast lumps are benign or noncancerous, some lumps are caused by breast cancer. It is suggested to consult a doctor for proper diagnosis it you think the lump is malignant or cancerous.
  9. Breast cysts: Breast cysts are fluid-filled lumps that are oval or round in shape, and feel smooth and firm upon touching. These cysts are benign or noncancerous. These cysts tend to move when pressed and usually appear within two weeks prior to a period and then disappear after the period.
