From the Research
Fibroids, more accurately referred to as fibroadenomas when occurring in breast tissue, can indeed occur in the tail of Spence, although this is relatively uncommon. The tail of Spence, also known as the axillary tail or lateral mammary gland, is an extension of breast tissue into the armpit area. Given that it contains the same glandular tissue as the rest of the breast, it is susceptible to developing fibroadenomas, which are benign (non-cancerous) growths composed of both fibrous and glandular tissue 1.
Key Characteristics and Diagnosis
- Fibroadenomas typically present as firm, rubbery, well-defined, mobile masses that may be tender, especially before menstruation.
- They develop due to hormonal influences, particularly estrogen, which explains their common appearance during reproductive years and potential size changes during pregnancy or menstruation 2.
- Diagnosis often involves clinical examination, possibly followed by imaging such as ultrasound or mammography, and sometimes a biopsy if needed to rule out other conditions 3.
Treatment Considerations
- Treatment depends on the size, symptoms, and diagnostic certainty of the fibroadenoma, ranging from observation for small asymptomatic ones to surgical excision for larger or symptomatic cases 4.
- The decision to treat is also influenced by the patient's overall health, preferences, and whether the lesion is causing any discomfort or concern.
Importance of Evaluation
If a lump is discovered in the tail of Spence, it is crucial to have it evaluated by a healthcare provider to determine the nature of the growth and appropriate management. While fibroadenomas are benign, distinguishing them from other breast changes or lesions that may carry a risk of malignancy is essential for proper care and peace of mind 5.
