18 F so you can imagine...
No underwired and front fastening. Ok the boobs won't quite hit your knee caps but you will get some supportThere is a positive to having a few front fastening bras. If you suddenly find your shoulder is buggered ( a medical term for shoulder incapacity) and you end up with surgery prohibiting the use of that arm for at least 6 weeks, doing a bra up and then undong it is an impossibility, especially if you live on your own, then the front fasteners come in very useful....
I have just been reading the blogs about skin care and radiation
Dove soap but the extremely sensitive/gentle (light green packaging) Moo Goo udder cream before radiaton starts and then several times/day during therapy but not 2 hours before radiation. If/when your skin breaks down - big boobs, go see the nurses for some dressings. The ones I had were almost foam like with a silicon base next to the skin so it didn't stick. the nurses dressed the reddened skin with a cream for burns (flamigel)until the skin broke then they changed it to another lotion
I found that front fastening bras and genie bras helped. I needed to have a dressing in place but I also found wearing a silk camisole next to the skin/over the dressing and under the bra helped. When I got home I just sat in front of the fan holding my boob up to get the air to it. Not a good look, but I didn;t care
Once the raditation changed from wide to narrow beam I was able to put sudacream (zinc znd castor) on the broken skin. It healed up really quickly
