Advice on bras

Hi. 

Yesterday I had it confirmed that I have a small but deep tumour in my breast. I'd been worrying myself silly in the last 17 days between having the biopsies and yesterday's results.

I'm all booked in to have it removed on the 15th March and I have 2 appointments booked in before that. One for a chat to the nurse, one to have a magseed inserted. 

My question is, does anyone have any advise or preference as to what bras to wear afterwards?

I'm an M&S 38dd usually, I know a good support is needed and easy to put on and off. I've seen Cotton Traders do one with a zip up front.

Thanks.......
