I’m 19 years old and have had swelling under my right armpit for some time now. I also have redness of both breasts which mostly covers both of them . I went to my gp and she referred me for a “mammogram “ . In the end I only had a ultrasound and she said that my lyth nodes are swalloen under my right armpit . She checked my breast but couldn’t see a lump . And that was basically it she told me to come back if it gets any worse ? I’ve had the swelling just under 6 months and the redness for about a month ? She said she was going to do a biopsy of my armpit but didn’t because she didn’t think it was “sinister” . I just kinda feel fobbed off just wondering isit because my age ? I have no pain in the breasts atall they just feel abit heavyier than usual they have also increased in size as I was a DD and now a e ? Just wanted some advice or help thankyou
