Fibroadenoma of the Breast

Question:

I have been diagnosed with a fibroadenoma, a benign tumor on my breast. Does this need to be removed? Will I need surgery? If so, how extensive will the surgery need to be?

Answer:

Fibroadenomas of the breast are benign growths. This means they are not cancerous. If the diagnosis is certain, you may not need it removed unless it is large. For a large fibroadenoma, it is best to remove the tumor surgically so that it can be processed and thoroughly examined in the laboratory. This can confirm if the tumor is benign.

When a fibroadenoma is left in place, the lump may remain the same size, enlarge or shrink over time. You should have the lump examined by a doctor and checked by a mammogram after six months. You want to make sure that it is not growing quickly. If it is growing quickly, your doctor will probably recommend that it be removed for processing and examination.
