Hey there!

I visited the breast clinic last year after discovering a lump on my left breast, rest assured it turned out to just be an infected cyst that was already beginning to sort itself out.

I was in a similar position as I was 22 at the time. I felt like my GP thought I was a bit of a hypochondriac at first because breast cancer was so unlikely at my age. However similar to yourself I know my own body and I know that this wasn't normal. My GP thought it was likely that this was related to hormones or periods and I'd just never noticed these changes before but because I have had cancer in the past (totally unrelated to breasts) she agreed to make a referral to the breast clinic to be on the safe side.

At the breast clinic the staff were all lovely, rest assured! They did an examination and had a feel of both breasts and armpits first then did a mammogram. Apparently mammograms are more difficult to read in younger women because their breast tissue is denser so they also did an ultrasound of my breast. I had a biopsy of the lump with a local anaesthetic (again, extra precaution because of my history of cancer). The doctor gave me a lot of reassurance that the lump did not appear cancerous and made me a follow up appointment for the following week to get the results. 
 

The follow up appointment was quick and straight to the point. The whole experience was fairly stress free (minus my own panicking thanks to dr Google). Try not to worry until the professionals give you a reason to!

I hope all goes well for you x
