I am sorry to hear that you have a lump in your neck and you are worried about what might be going on. I am happy to give you some of my thoughts about what might be going on, and to direct you in the right direction to get the answers that you need. Ultimately I am going to recommend that you make an appointment with an ENT (Ear Nose Throat) physician, or otolaryngologist
. They are well equipped to diagnose and manage neck masses, and will be able to help you figure out what might be going on. I am a little unsure by the information that you have given, but you make it sound like you already have a diagnosis of lymphoma
of the neck. As I am sure you are already aware, lymph nodes are a normal part of your immune system, and you have hundreds of them in your neck. They can be swollen or enlarged for a number of different reasons (ranging from a common 'cold' to a neoplastic process like lymphoma). Lymphoma is a blood cancer that results in the overgrowth of immune cells (lymphocytes). One way to get a diagnosis of head and neck lymphoma is to perform a biopsy (incisional or excisional) to remove some of the tissue and send to a pathologist
. Again, please schedule an appointment with an ENT. I hope this helps, and wish you all the best at the ENT visit.
