Benign tumors are less spoken of than malignant tumors; hence, they are not the first thought on women’s minds when they learn that they have a lump in their breast.The most common benign breast tumor is called a fibroadenoma. Fibroadenomas commonly occur in young women who are between the ages of 15 and 35, but they may occur in older or younger women as well. The cause of fibroadenomas is unknown, but the believed cause is fluctuations in reproductive hormones. The signs and symptoms can be felt or seen on imaging tests.
A fibroadenoma is a solid lump that is round with smooth edges. It can also feel elastic or firm. According to the mayo clinic, many women report it feeling “like a marble under the breast.” It typically does not produce pain and can easily be moved under the skin when examined.
