I have a gumball shaped object under my skin in my armpit it is in constant pain but it doesn t hurt that bad unless pressure is applied there is nothing on the surface implying a boil so I m wondering what it may be is it a tumor or cancer I m not sure should I be concerned?
Swelling in an armpit without overlying puncture or skin changes normally means enlarged lymph nodes. Lymph nodes are part of body immune system to fight infections or anything that is foreign to the body including cancers. You Need to have history and examination by a GP, blood complete picture to see for an infection, an ultrasound of maxilla(armpit) and ESR levels and CRP levels. A fine needle aspiration for cytology may eventually be required. Please consult your doctor.
