How are you? How is your mother? Was there a previous injury to breast? Is there a family history of breast cancer? A breast lump is a growth of tissue that develops within your breast. There are many causes of breast lumps. Some of these causes are harmless, while others can be dangerous. Lumps in a woman are often caused by injury, infection, fibrocystic changes, fibroadenomas, cysts and even cancer. It would be best to consult a doctor for proper evaluation of the breast lump.
Take care and keep us posted.
A lump in the breast can be caused by many things but I would advise you to encourage your mother to see her Family Physician so that he/she can examine her breast and perhaps order a Mammogram to find out exactly what is going on. This could be something very simple but it's best to find out for sure.
