I just had my 2nd annual mammo last week. To choose a time of the month when you’re less tender makes a difference… they say the best is about a week after the first day of your period.
I am quite well endowed, so they have to squish a lot, which is uncomfortable, but I haven’t had lingering aching or anything. I have wondered if it’s more uncomfortable for smaller women.
As for deoderant/antiperspirant, I was told not to wear it. The antiperspirant does contain aluminum, so I guess that’s the issue – but they probably tell women not to use anything as a safeguard. I was also told not to use any powders. I just scheduled mine for 1st thing in the morning and put my deoderant in my purse.
