[|AI|]  Hello, Carol,I have gone through your query. Thanks for using Chat Doctor. Actually I need exact reports of echo and x-rays to guide you properly. You have rightly considered it serious. There are some tumors in heart which need urgent surgical removal. You have not mentioned whether mass is within the cavity or external to it. Excessive use of arm does not produce a tumor however it may lead to hematoma, if send me complete details I would be happy to guide you perfectly best wishes Chat Doctor.
