Hormone replacement therapy and oral contraception can also affect the size of a fibroadenoma. A healthcare professional can determine whether a lump is a cyst or tumor.
If the lump is fluid-filled, it may require no treatment at all. Those symptoms may worsen and get better at different points in the menstrual cycle.
If at any point your doctor feels that the cyst has suspicious features suggesting it could actually be a breast cancer, he or she can order a biopsy to make sure any solid parts inside the cyst are benign. If a biopsy proves that a breast lump IS a fibroadenoma this result is benign with no increase in the risk for breast cancer. Be Informed and Ask the Right Questions.
Breast cysts are round or oval structures filled with fluid. If the cyst comes back, it may be evaluated again with mammogram and ultrasound, and it can be drained again. If a biopsy proves that a breast lump IS a fibroadenoma this result is benign with no increase in the risk for breast cancer.
