Hair growing on chemo!

I’ve had 3 out of 6 chemo treatments. Half way through!
But Im becoming more and more concerned over my growing hair…I mean if the hair can grow, what about the other thing? :frowning:
My family think Im silly worrying, as I still obviously look completely bald, but it is growing.
Am I being silly?

Hi tree chemo is doin its job no need to worry bout that my hair started to grow during chemo was well chuffed too my tumor was 9cm when chemo had finished it was 2cm
