My mum was diagnosed with stage 4 Bowel Cancer along with secondary liver cancer, three weeks ago. She is due to start her chemotherapy treatment in ten days time. I live two hours from my parents so usually visit for a weekend or longer. How safe will it be for us to visit mum once she begins treatment? Is there a point in each cycle where there is more risk or less? I desperately don't want to put her at any risk of catching anything. I have two secondary school aged children and I work in childcare.
