I've had a lump in my left armpit for 6months now, I've only just plucked up the courage to ring the doctors for an appointment. I've managed to somehow get an appointment on the same day as phoning them. I'm so nervous to go :( so scared of what they are going to say or do. I just don't know what it could be, there's loads of things that I have read what it could be; Cancer (loads of different kinds), reaction to covid booster (very unlikely as it's been 6months since my jab), hormone imbalance, cycst etc. The lump I have is not painful at all (sometimes it does make my shoulder/collar bone slightly ache). I'm 29 I don't think I have any cancer history in the family but then I don't really know much about my family so it doesn't really help. If anyone has anything similar please share your story. Thank you

Edit: I have been for my appointment today and the dr could not feel anything an did a thorough breast check. She couldn't feel anything where I've been feeling the lump and just thinks I'm feeling muscle. I sort of feel reassured about it, and just going to see if the lump I'm feeling goes. She did say if anything changes to go back.
