January Ultrasound: Small Further Response

One of the anchor points during chemo is the “how is it responding?” scan.

On 22 January 2026, I had a targeted ultrasound of the right breast and axilla to check progress on neoadjuvant chemotherapy.

What the scan showed (in plain English)

The breast tumour

The main tumour in the lower outer quadrant measured:

• 14 × 14 × 14 mm
• Previously 19 × 14 × 15 mm (from the December ultrasound)

There was also a small “satellite” nodule measuring ~5 mm. When the radiologist looked at the total area (main tumour + satellite), it was estimated at ~30 mm, which was essentially stable-to-slightly smaller compared to the prior estimate (~31 mm).

The lymph nodes (axilla)

The key lymph node that had been marked earlier (with a HydroMARK) measured:

• 11 × 5 mm
• Previously 13 × 8 mm

And importantly:

• No other abnormal axillary lymph nodes were identified on the scan.

The radiologist’s conclusion

The report wording was simple and exactly what you want to hear mid-treatment:

“Small further response to treatment.”

It’s not the final answer (surgery pathology is), but it’s another data point in the right direction.
