Breast tumours are the abnormal growth of cells or tissue in the breasts, which can be benign or malignant. If there is any suspicion of a tumour, medical tests need to be carried out in order to analyse the nature of the tumours. If they are cancerous tumours, depending on its size and grade the doctor will prescribe chemotherapy, radiation or surgery to remove it. However, benign breast tumours are growths that have no carcinogenic nature. The most common are fibro adenomas, and is more common in women under 30 years of age. It is related to hormonal changes in women, and not always need to be removed, since most of them will disappear within two years. A patient can opt for surgery to remove benign tumours when their growth is quick, they cause deformity or discomfort. Some other benign breast tumours or conditions include fibrocystic breast disease, a condition in which the breast develops benign lumps, adenomas, lipomas, etc.
