Hi, hoping someone can give some advice. A close female relative has been having constant headaches for the past nearly 2 months. The doctor has arranged for blood tests and an urgent scan of her head. I’m worrying. Can anyone help with any possible diagnoses? I have gone into worry overdrive. She’s had cancer before about 3 years ago, Has had all the usual checkups and all has been fine but I’m worrying she could now have it again. Is there a higher chance of you getting cancer again if you have had it once? The cancer previously was colon. Thank you.
