GORGEOUS!!  @tigerbeth   Lovely pics - Proud Mum!  :)  
All the best with your rads ...... I didn't have too hard a time of it .... so hope you don't either. xxxx   Make sure you lather up with lotions & potions immediately after & 2-3 times a day - just not BEFORE the rads.  Only after.
Do you have to travel far for the treatment?  I hope not - and I hope you have someone to drive you to & from.  
You'll get used to flashing your body at all number of strangers over the next 4 weeks ..... 
I was surprisingly emotional on my final session .... it caught me unawares!! They'd become 'part of my family' for the 4 weeks ..... be kind to yourself xxx
