I can't really believe i'm posting here again (I went through screening for lymphoma earlier this year) but I noticed a lumpy or thicker area in my breast in September, and have been ignoring it until now mainly because I wasn't sure exactly what I was feeling and because of all the tests i've already had. It may be slightly bigger than when I first felt it but I'm not really sure. It is nearish the nipple, between 1oclock and 3oclock of my breast. I can't work out exactly what shape it is, it doesn't feel like an obvious smooth round grapelike thing but like a thicker area of lumpy tissue. I don't think it is moveable but its not rock hard like concrete either - its more firm but rubbery. It also feels more obvious in some positions than others. I have small breasts which makes it even more confusing because I can feel my ribs if I press too hard. Its completely painless, even with deep palpatation.
I feel silly going to the GP if it is just normal tissue, because I even had a PET scan in July so wouldn't this have shown up if it was anything? All my pet scan showed was mild uptake in right sided neck lymph nodes and "brown fat" uptake in chest, armpits, etc. The dr who examined me in July must have thought some of the tissue near my breast in my armpit felt a little off but not significantly because she said "hmmm" then paused and said "actually that could be normal tissue" but she didn't feel my actual breast... I felt my breast afterwards and didn't notice anything at the time.
'm also only 22 so I know the odds of it being cancer are extremely low and am therefore not really all that worried, but I have had a fair bit of radiation this year (2 ct scans, chest xray, pet). I just don't want to go to my gp and seem like the biggest hypochondriac ever because I already had loads of screening for my lymph nodes, and I'm also reluctant to even go for more screening at all because it was such a horrible time waiting to find out.
