Hello Maryre123

I'm sorry to hear about your sister's diagnosis and that despite having been looking well, she has had some new health concerns during the past few weeks. It's understandable that you're feeling anxious about the changes. 

It's impossible for anyone to say with certainty what is causing her headaches and it could be something completely unrelated to her cancer so try and encourage her to contact her GP if she's not comfortable with contacting her cancer nurse. It's understandable that she is perhaps reluctant to seek help with the possibility of there being more bad news but it could be that the health professionals involved in her care could improve these symptoms. 

If either you or she would like to chat things through with one of our nurses then you're most welcome to give them a call. I know they will be happy to listen and offer any advice, information and support they can. They're available Monday to Friday 9am to 5pm on 0808 800 4040. 

I hope that you can find a way for your sister to access the support she needs. 

Best wishes, 
Jenn
