<human>: My 4 year old grandson has a large lump on the right side of his chest, next to his breast. It is about the size of a golf ball and is very hard. He says it does not hurt. He doesn t have any other symptoms and has not fallen or be knocked hard, etc. What would this be?
<bot>: HI. Thanks for your query and an elucidated history. It is very rare for such a large and hard lump to be developed on the chest of such a small boy of just 4 years. This may be diagnosed only by an ultrasonography, FNAC to start with. I would suggest you to consult a Pediatric Surgeon or a General Surgeon and get this removed under General Anesthesia. This will benefit us by two ways:1. We get rid of the lump, so the disease is out. 2. we get a definite diagnosis by histopathology examination of the lump after removal.
