In brief: No
Fibroadenomas are the most common benign tumors of the breast.
They are often estrogen sensitive and are prone to grow in estrogen-rich environments. Accordingly, it is not uncomon for these to develop after puberty, pregnancy, or following the use of birth control pills or hormone replacement therapy. If a biopsy has been performed to establish the diagnosis, they do not need to be removed.

In brief: No
Fibroadenomas are common, benign lesions.
Along with cysts, these are the most common causes of a breast mass, particularly in younger women. They aren't cancer, don't turn into cancer, and aren't associated with a high risk of eventually developing breast cancer. Surgical excision is an option, and sometimes recommended if they are getting bigger. Cryoablation is another option.

There are giant fibroadenomas that can be malignant but they are called cystosarcoma phylloides which can be benign or malignant.

In brief: No
A fibroadenoma is a benign growth - not a cancer.
They are common, and often remain stable in size. However, you should see a physician if you detect any mass in your breast. Demonstrate to the doctor exactly what you feel, especially your doc does not discover it during your breast exam - do not just ignore it. Discuss what it might be and plans for follow-up.
