my son is having tumors near left side of the neck is it serious doctors are telling these are lymph nodes the size is increased from previous

A. Sir already done a testing and the doctor suggested if it is lymph node then it’s okay it increases sometimes and can create problem of pain and swelling so if it is a situation where it is need to be operated then they can actually take It off that way but I would recommend you to take a second opinion before you go ahead with anything
