proceed with scheduled surgery? lump has gone smaller

User Profile
In July last year, I found on my 2year old son, a small slightly moveable lump about 2cm long just below the skin across his inner left forearm. Over the next few months, it grew bigger very slowly to 3cm long and moved down the arm. In January this year, it became very big about 5cm long and bulged up. A few days ago, it's suddenly become very small and back to 2cm long. My son has only said it was painful once when it grew bigger and never since. No other signs of pain or discomfort. What does it mean if the lump has gone smaller, and should we still proceed with scheduled surgery?

Hello and Welcome

I appreciate your concern

The lump seems to be an enlarged epitrochlear node. You should definitely go for an excisional biopsy as its a minimally invasive procedure and would rule out any serious cause such as a malignancy. Lymphadenopathy can be due to a viral infection or a localized infection draining into the node.

wishing you best of health
