Hello Dr. CranquisYesterday someone pointed out I have a large, swollen lump on my neck- it's painless, I didn't even notice it, but I was wondering if you knew what it would be?It's at the front of the neck- one side is totally but the lump on the other side is pretty large, about 4cm in diameter. It's quite soft and seems to have just appeared out of nowhere.I've did a little research and looked at some images- it seems like it's a goitre. However, whilst it's probably harmless- is there any need to get it checked out if I'm not experiencing any 'symptoms' as such (with the obvious exception of a visible lump)? Would it be ok to leave it a little while to see if it disappears on its own?Most of the stuff I've read indicates that goitres are often due to iodine deficiency- I checked the sources of iodine and that's very unlikely. There is a lot relating to hyper/hypothyroidism. I don't know too much about thyroids but reading around the symptoms, this also seems unlikely- I'm an 18 year old female, maintain a normal, healthy weight and never experience poor health in any way. (And I'm definitely not pregnant...)So, any clues as to what might cause the quick appearance of a lump like this? And should I do anything about it?Thanks!
Hello there, Toad with a Node --
Well, there's a few possible causes (besides a thyroid goiter), and the potential diagnoses would depend greatly on exactly where the lump is located.
Smack dab in the anterior (front) midline of your neck, around the "Adam's Apple" that moves when you swallow: thyroid nodule (an isolated lump growing on the thyroid gland) or a goiter (diffusely enlarged thyroid gland) -- often slow-forming.
Smack dab in the anterior midline neck, but higher up than the thyroid location, near where the chin meets the neck: thyroglossal duct cyst -- can swell rapidly or slowly; often will "move" when you stick your tongue out.
Off to the side on the neck: branchial cleft cyst, cystic hygroma, ranula, an abscess/pus-pocket (which would certainly be painful), and (most commonly and nothing-to-worry-about) reactive lymph nodes swelling up in the anterior cervical or submandibular chains in response to a local viral/bacterial infection, which should calm back down within 4-6 weeks after the head cold, etc.
The rapid onset + the rather impressive size of your neck lump may bear checking out with a doctor. Definitely get it checked out if it is painful, oozing/leaking, red and hot to touch, continues to swell rapidly, causes trouble for opening your mouth or swallowing, or if it doesn't go away on its own in 3-4 weeks.
