Thanks for your question.
It seems your doctor did not feel any lymph nodes under arm pit.
Soft squishy painless swelling is likely a benign fat cyst or lipoma.
This is the most likely diagnosis which is bening.
Cancerous growth is solid or hard and usually causes change in breast appearance if so much palpable, along with enlarged lymph nodes.
In the absence of these findings, I will not consider this as serious finding.
The specialist will also confirm this view.
