Welcome @Perth_girl77 .... feel free to put your story so far on the 'new diagnosis' category - then it almost becomes a bit of a diary for you too ;)
https://onlinenetwork.bcna.org.au/categories/newly-diagnosedYes, you start with the lotions (MooGoo is very good) from the first day, but only AFTER your treatment, never before.
I only had a little bit of skin breakdown in the last week of Rads - and even then, not badly. At the end of my Rads & the Booster Rads, the hospital pharmacist suggested me using a Baby Rash Cream that was called BOZ ..... it is very thick tho .... and recommend using those Blue Kitchen 'paper cloths' between me & my clothes.
Make sure you tell the Nurses if you notice
any extreme redness during the treatments and particularly if your skin actually breaks or blisters - My Rad Onc checked up with me as well, at least once during the 4 weeks of treatment.
If your skin gets red early on, ask about the use of Mepitel Film - it is a bit like Cling Wrap that is put onto your skin, to help protect it. xx
take care & all the best for your ongoing treatment xx
