Sorry to see you here on Xmas Day, @Bluebell5 - but welcome to the blog! (And please DON'T use Dr Google!! Everyone's case is very individual & so much info that pops up on Dr Google is 10-20 years old & totally obsolete to modern doctoring!) . It is also often WRONG!
Try not to overthink it all (difficult tho it is ...) as your onc will be the one to guide you thru the maze.
Take care, enjoy the Xmas break - keeping yourself busy with family & friends ..... and no need to rush into doing that will, I reckon! xxx
