I have a lump on the right anterior triangle of my neck for 9 weeks. Is it lymphoma?

Hello doctor,

I am a 21-year-old female. I have a lump in my neck for about nine weeks now. It is between my hyoid bone and sternocleidomastoid muscle on the right anterior triangle of my neck. It is palpable when I tilt my head back. It is probably as big as a penny but not as round as a penny. It is oval shaped and non-tender. when I first noticed it, it was the size of a kidney bean but then two weeks later it shrunk down to the size of a baked bean and has stayed this size for seven weeks now. It never went back to kidney bean size and it is been two months I noticed the lump. It will move left and right, but not up and down. It feels firm when I tilt my head back but soft when I have my head upright normally. When my head is tilted back and I put my fingers on it, I can feel a pulse. But when I put my fingers on the other side of the neck I can feel a pulse in the same spot, where there is no lump. Just curious as to what this could be? I do not feel any other lumps or bumps that are larger than a pea size, and I am not sick and I was not sick when I first spotted the lump either.

Does this sound like lymphoma to you, considering the location, and shape and what it is doing? From what I read, hodgkins lymphoma is common in my age group but rare overall. I do not have any other symptoms (fever, night sweats, weight loss, loss of appetite) other than just a random lump in the middle of my neck.
