Hello I’ve been getting a cyst under my armpit every so often. I haven’t got one in about a year and have recently seem to have gotten one again. About a year ago I went to the doctors and got it removed he said it was a benign cyst and I just got another one in about the same spot as the one I got removed a previous year ago just a little bit lower. My question is do you know any reason why I may be keep getting them it seems to only be in my left armpit but I think I had one in my right armpit a while back but not completely sure. I thought maybe it as the deodorant I’ve been using so I changed and used Dove for men and didn’t seem to get anymore for a long time but now I got another one it has white pus coming out when I squeeze it and seem to have gotten smaller since some pus came out about a week back. Just worried it may be cancerous or something seeing I keep getting them over and over again. I am a 19 year old male by the way.
