Fibroadenoma
Fibroadenomas are common benign (non-cancerous) breast lumps that frequently occur in young women, typically between the ages of 15 and 35. These lumps are composed of both glandular and stromal (connective) tissue and are usually smooth, firm, and movable under the skin.
What is a Fibroadenoma?
A fibroadenoma is a solid, non-cancerous tumour that can vary in size from less than a centimetre to several centimetres in diameter. These lumps are generally painless and can be singular or multiple. They are known to respond to hormonal changes, often enlarging during pregnancy or hormone therapy and shrinking after menopause.
Causes of Fibroadenomas
The exact cause of fibroadenomas is not well understood, but they are believed to be related to hormonal changes in the body, particularly those involving oestrogen. This is why they are most common during the reproductive years and may fluctuate in size with menstrual cycles.
Symptoms of Fibroadenomas
Lumps: Fibroadenomas are typically felt as smooth, firm, rubbery, and easily movable lumps in the breast.
Size and Texture: They can vary in size and may feel like a marble within the breast tissue.
Painless: Most fibroadenomas are painless, though some women might experience slight discomfort or tenderness.
Diagnosing Fibroadenomas
Diagnosis usually involves a combination of physical examination, imaging tests, and sometimes a biopsy, typically as follows:
Physical exam: Your doctor will palpate your breast to feel the characteristics of the lump.
Imaging: Ultrasound or mammography can help distinguish fibroadenomas from other types of lumps.
Biopsy: In some cases, a needle biopsy may be performed to confirm the diagnosis by extracting a small sample of the lump for microscopic examination.
Treatment of Fibroadenomas
Most fibroadenomas do not require treatment and can be monitored through regular check-ups and imaging. However, treatment may be recommended if the fibroadenoma is large, growing, or causing symptoms.
Regular follow-ups to monitor any changes in the size or feel of the lump will be recommended, and if necessary, fibroadenomas can be surgically removed, especially if they cause discomfort or anxiety.
What’s next?
Fibroadenomas are a common and generally benign condition, most often seen in younger women. While they typically do not pose a significant health risk, it’s important to monitor them and seek medical advice if there are any changes. Regular check-ups with your oncoplastic breast surgeon can ensure that any changes are promptly addressed and managed appropriately. If you have any concerns or notice new lumps, consult your healthcare provider for a thorough evaluation and peace of mind.
