I am a 25 year old female.
I have found a pea sized which is completely painless lump in my left armpit. It's right at the top of my armpit and feels hard and mobile. There is no redness or swelling, which concerns me as it leads me to think it isn't an infection. I do not currently have any form of viral infection and haven't had one recently. I noticed the lump about 2 weeks ago.
There is no real history of cancer in my family, but I am concerned that this could be lymphoma. I did go an see my doctor about this and he said it did not feel sinister and he thinks I should allow 6 weeks for it to potentially go down. He advised me to come back in again and see him if it's still there. Although, I would like to trust my doctor, I really feel I should have some form of biopsy carried out. I have huge anxiety about this at the moment and feel like it's preventing me from enjoying my life in the mean time.
Please can you advise?
