Your comment is sooo interesting as I noticed the same thing for yrs but never put the two together. What I did notice is my sweet highly intelligent dog kept prodding my right breast. I began checking my breasts very carefully when she did this. She, Ellie, is an Australian Sheperd that had an incredible sense of smell. (side note, Ellie just passed away very from a highly aggressive canine breast cancer last week within a month of notable tumors. I was due for my annual gynecology exam with a mammogram that I never skip or put off. That is when my mammogram called me back for further diagnostics in May 2022. Thank you for posting as now I know why my deodorant and frequent bathing didn't help. I had a double mastectomy with multiple lymph nodes removed and it seems to have settled back to my normal. This actually makes sense. I hope this is studied further so it can be considered a red flag for further follow-up.
