📋 FibroRisk – Risk Assessment Calculator for Fibroadenoma and Phyllodes Tumor

Your age: How big is the lump? (in millimeters):

📷 How to make sure the size was measured correctly?

Accurate measurement is important for proper risk evaluation.

📏 If possible, the lump should be measured in three directions (length × width × depth).
⚠️ Measuring diagonally can give a larger than actual size.

❌ Incorrect example:

✅ Correct example:

If you had an earlier scan – what was the size back then? (mm): How many months passed between the two scans? How long have you known about this lump? (in months) Date of your last check-up (if known): What did the doctor tell you? Previous biopsy result: How does the lump look on the ultrasound? Are there small cysts inside the lump (≥3 mm)? Microcalcifications on imaging: BIRADS category (if you know it): Is this a new lump? How many similar lumps do you have? Do you have close relatives with breast or ovarian cancer? Are there known inherited mutations in your family (like BRCA1 or BRCA2)? Do you have any worrying symptoms? (pain, hardness, changes) Are there any skin or nipple changes? (dimpling, redness, sores) Is there any discharge from the nipple? Is there any visible difference between the two breasts? Does the lump change or hurt during your period? Do you know what frequency was used for the ultrasound? (Usually shown in a corner, like “12M”) What is your breast density (from the report)?

🔬 Biopsy results (optional)

Mitoses seen under microscope (per 10 views): Ki-67 index (%): p53 result: CD34 result:

👩‍⚕️ Self-check advice

Do a self-breast exam once a month — about 7 days after your period starts.

Any new lump, firmness, or change in the skin should be checked by a breast specialist (breast surgeon).

🧪 Why is breast density important?

Women with high breast density (type C or D) have a higher risk of developing breast cancer.

Studies show they may have changes in gene activity (like in apoptosis, PI3K/AKT, or EGFR), which can make cancer growth easier.

⚠️ High density also makes it harder to detect small lumps on standard ultrasound.

🧪 Types of biopsy

📌 Fine-needle aspiration (FNAB) – often used for cysts or superficial lumps.

📌 Core biopsy – the standard method when fibroadenoma or phyllodes tumor is suspected.

📌 Vacuum-assisted biopsy – used for larger or hard-to-reach lumps.

📊 Difference between simple and complex fibroadenoma

Feature	Simple	Complex
📷 Ultrasound appearance	Even, oval shape	May contain microcysts or bright areas
🔬 Histology (microscope)	Uniform stroma (tissue)	Microcysts ≥3 mm, apocrine changes, calcifications
📈 Risk of future problems	Very low	Slightly increased risk of other breast changes
🧬 Genetic profile	Often MED12	MED12 + PIK3CA + RARA (possible)

⚠️ If a complex fibroadenoma is suspected, follow-up or histological confirmation is recommended.

🩺 How to recognize warning signs?

A lump you can feel – hard, fixed, unclear edges
Skin changes – dimpling, redness, "orange peel" appearance
Nipple discharge – especially bloody
Asymmetry – one breast visibly different in size or shape

💡 Why follow-up testing may be needed

Even benign (non-cancerous) lumps like fibroadenomas can grow. In rare cases (around 2%), they may turn out to be a different tumor, such as a phyllodes tumor.

Repeat biopsy or getting a second opinion can help avoid unnecessary surgery or missed diagnosis.

📋 ASBrS Cryoablation Criteria

✅ Sonographically visible lesion
✅ Histologic confirmation of fibroadenoma (core biopsy)
✅ Size < 4 cm
❌ No suspicion of phyllodes tumor or malignancy
❌ No imaging-pathology discordance

Meets criteria? If yes, cryoablation or vacuum-assisted excision may be appropriate.
