Fine Needle Aspiration Biopsy (FNAB)
Hello Dr.
Chen, I have a cyst (it appears as an oval, dark structure on the ultrasound).
I feel that it has been growing, so I asked the doctor to aspirate it.
The result was "Breast, aspiration, atypia.
Sample adequate for interpretation." What would be the best course of action moving forward? Is there a high risk of breast cancer? Thank you.

Simple cystic lesions are generally aspirated only for decompression to alleviate symptoms, and further cytological examination often lacks practical clinical significance.
Only in the case of complex cysts is aspiration followed by pathological cytological examination recommended.
At this point, the information regarding atypia is insufficient for further differential diagnosis.
For example, the presence of macrophages indicates a previous inflammatory state, while the presence of papillary epithelial cells suggests a possible papillary mass (which cannot be definitively classified as benign or malignant).
All of these findings can be categorized as atypia, but they are still quite distant from a malignant diagnosis (with a low likelihood).

More Info
When it comes to managing a cyst, particularly in the breast, the results of a fine needle aspiration (FNA) can provide crucial information for determining the next steps. In your case, the report indicates "Breast, aspiration, atypia," which suggests that while the sample was adequate for interpretation, there were atypical cells present. Atypical cells can be a cause for concern as they may indicate a higher risk of breast cancer, but they do not confirm a diagnosis of cancer.
Next Steps for Cyst Management
1. Follow-Up Consultation: The first step is to schedule a follow-up appointment with your healthcare provider or a breast specialist. They will discuss the FNA results in detail and help you understand what atypical cells mean in your specific context.
2. Further Imaging: Depending on the characteristics of the cyst and the atypical cells, your doctor may recommend additional imaging studies, such as a breast ultrasound or a mammogram. These tests can help assess the cyst's size, shape, and any changes over time.
3. Biopsy Consideration: If the atypical cells raise significant concern, your doctor may recommend a core needle biopsy or excisional biopsy. A core needle biopsy involves removing a small cylinder of tissue from the suspicious area for further examination. An excisional biopsy involves surgically removing the entire cyst or lump for analysis. This step is crucial for definitive diagnosis and to rule out malignancy.
4. Monitoring: If the cyst is not deemed high-risk and the atypical cells are not concerning enough to warrant immediate intervention, your doctor may suggest a watch-and-wait approach. This would involve regular monitoring of the cyst through follow-up ultrasounds to check for any changes in size or characteristics.
5. Risk Assessment: Your healthcare provider may also assess your overall risk for breast cancer based on family history, personal medical history, and other factors. This assessment can guide decisions about further testing or preventive measures.
Understanding Breast Cancer Risk
The presence of atypical cells does increase the risk of developing breast cancer compared to normal cells, but it is essential to understand that not all atypical findings lead to cancer. The degree of atypia, the specific type of atypical cells, and other factors will influence your individual risk.
- Risk Factors: Factors such as age, family history of breast cancer, genetic predispositions (like BRCA mutations), and personal health history play significant roles in determining your overall risk.
- Regular Screening: Regardless of the findings, maintaining regular breast screenings is crucial. This includes annual mammograms starting at the recommended age, or earlier if you have risk factors.
- Lifestyle Modifications: Engaging in a healthy lifestyle, including a balanced diet, regular exercise, and avoiding tobacco, can help reduce your overall cancer risk.
Conclusion
In conclusion, while the presence of atypical cells in your cyst raises some concerns, it does not automatically indicate breast cancer. The next steps involve further evaluation through imaging and possibly a biopsy to clarify the nature of the atypical cells. It is essential to maintain open communication with your healthcare provider to ensure that you receive appropriate follow-up care and monitoring. Remember, early detection and intervention are key components in managing breast health effectively.
