Welcome to health care magic.
1.Lump in the armpit / axillary region with out pain, tenderness suggestive of lymph nodal enlargement at first place and
lipoma, vascular causes on the second place.
2.If you are my patient i would have examine first and ask for a
ultrasound axillary region - ultrasound will give me the nature of the disease, its source and extensions.
3.Lymph nodal enlargement is seen because of the underlying medical conditions any infections / inflammation it can be localised or systemic or possible lymph nodal pathology itself (
lymphadenopathy)
4.So one has to find out the cause - if required FNAC - fine needle aspiration cytology will gel to evaluate the cause and cells involving.
5.I can understand your financial status but this is the standard procedure one has to follow. Try the way you can do so. Good luck.
Hope i have answered your query.
Any thing to ask do not hesitate. Thank you.
