[|Human|] I have a small dime size subsurface lump on the right side of my right pectoral. Theres no pain when i press around it, but if I press the lump itself an irritation feeling begins with slight pain. Its about an inch and a half away from my nipple. havent noticed this lump until last night after my light, no weight work out session. Workout session consists mainly push ups and crunches.  Any idea on what this lump may be and what treatments I can do at home? Please and thank you. V/RJM
[|AI|]  Welcome to Chat Doctor. 1. The possible cause could be lipoma (fat containing) as there is no pain or tender.2.I would suggest getting an ultrasound scan done - ultrasound will help in evaluation of the nature of the lump, its source and extensions. 3. If there is any mass noted on the scan - a guided FNAC - fine needle aspiration cytology will be helpful to know the nature of the cells.4. Since its area or chest, male breast lesions also can not be ruled out.5. So get an appointment and get the scan done and needful treatment. Good luck. Hope I have answered your query.Anything to ask do not hesitate. Thank you.
