You should see a doctor. It could be polyps or cancer or a fish bone. No telling! It isn't worth wondering, best go get it looked at.\n\nI felt like someone was choking me so I went and asked my doctor, as it turns out, my thyroid had grown back over the last ten years since it was taken out and it was filled with nodules. Go figure! No one expected that answer.

Possibly a fatty tumor, harmless but can be annoying and cause discomfort if it gets quite large.\nDoctor will need to take a tissue sample of it to rule out other concerns. Can opt ot keep it there or have it removed later.

It could be swollen lymph nodes due to infection.  Have a doctor look at them.  FYI, swollen lymph nodes could be a sign of lymphoma, but is usually not.  A  doctor can tell you if its an infection that needs to be treated w/a course of antibiotics.

A new blood clot could maybe be there, perhaps there is enough lateral flow to keep the swelling subsided.  But I'm thinking more likely it could be a lymphatic problem and fluid is accumulating lymphatically.  Definitely keep on top of this with your doctor!  Get well!

Probably not a tumor but get it checked. Have you been checked for mono or strep throat? They both hurt when you swallow.

can you get hold of it and move it around freely between your fingers (it isnt attatched to the bone or anything else) then it is a cyst,or if it is where your adams apple is it could be a growth on your thyroid gland.get it checked.

Go to the Dr.!   \n\nI have lipomas, they sound bad but are really just fatty lumps under the skin.  My brother in law had some removed. Cysts are common too, and usually are not malignant but you need to get it checked out. My husband has had one removed, he was fine.\n\nYou need to get these checked out to make sure they aren't cancer, especially if it's in the breast area.  This will help you stop worrying and to realize what's going on.

It is likely a swollen lymph node and not a big deal.  However, I just got finished being treated for Hodgkin's Disease (Lymphoma, cancer in the lymph nodes and lymphphatic system)\n\nI had nodes in my neck and arm pit swell and the ones under my arm were tender even though it was cancer (often if they're tender it's just a benign cyst and nothing to worry about)\n\nYou should never feel stupid when it comes to ensuring your own health!  I just turned 25.  A lot of people didn't believe I had anything serious either, even my doctors at first, and I had cancer!  So it's best to just get to the doctor and get it dealt with early.  Luckly we caught mine in stage two and now I'm in full remission.

The diagnosis is difficult and it depends on exactly where this bump is, the shape of it,  how old you are, if you are a man or a woman since some lesions are more prevalent in one gender or the other. Also it depends on if you have teeth or have dentures. The diagnosis could range from a bony growth (torus) to malignancy, from an abcess from a nearby tooth to a cyst from a structure in the palat. It could be a discoloration from a silver filling nearby to a lead tatoo if you are a pencil chewer.Although your dentist have not said anything to you I suggest for you to go and see you doctor or you dentist specifically for this if not just to put your mind at ease.

macro-lobulated mass, I pressume you mean.\n\nThis is bad, it is likely cancer.  Tissue is the issue, no answer until they have a tissue diagnosis.  If he smokes, then it is likely very bad news.\n\nBiopsy is everything, but odds are not great.  Anything other than cancer is going to have a pretty good prognosis, and thus not worth discussing until the biopsy is done.

No one can give you an answer unless they are a doctor, take this lump seriously because it could be something serious. Don't be embarrassed to talk to your parents because it could save your life. A nurse told my son that there was nothing wrong with his testical, and now he has testical cancer and he is going to be a very ill young man of 26 and he had a lump. Best of luck and God guide you to the right decision.

Could be a benign cyst.  Could be an infected lymph node.  Could be something more serious.  Go to your doctor right away!

It might be a osteosarcoma but if you are under 45 years of age and because the mass is on the end of a long bone then another strong possibility is that it might  be a giant cell tumor. Giant cell tumors are not malignant but still are still a difficult tumor to remove. Osteosarcomas are malignant and will require additional treatment besides tumor removal.\n\nhttp://www.emedicine.com/radio/topic307.htm\n\nhttp://www.emedicine.com/orthoped/topic531.htm\n\nThey won't be able to be 100% sure what it is until they take a biopsy and you need to get the biopsy done as soon as possible, because if it is an osteosarcoma then you need treatment sooner rather than later for the best outcome. Suggest you go to a large medical facility and be treated only by an orthopedist who specializes in bone tumors because you may need significant reconstructive surgery and this requires an expert surgeon.  good luck

If it's getting bigger, you should definitely have it checked out.  Your doctor can then tell you if you should have it removed.
