Critical illness cover - any recommendations?

Hi everyone,

could really do with recommendations for insurance companies that are able to provide critical illness cover for my partner who over 5 years ago had Castelman disease and malignant melanoma in situ. She had operations at the time which successfully removed both which were limited to just her lymph node and left shine and has had no further issues since. 
 

I have noticed when trying to obtain quotes many insurers have naturally rejected insuring her but this is something I am keen to ensure she has.

thanks
