I'm so sorry to hear this; I know how hard it is. I could tell you not to worry but it's easier said than done. The waiting game is horrible and scary. Try to keep as busy as you can and not dwell on the worst case scenario. It's hard but you'll go insane worrying. I'm in the same boat; my mum has been diagnosed with lung cancer. I'm so scared. Even though the consultant seemed positive and said it's treatable though not curable, it's scary. Cancer is as scary as ***. We've got to try and be strong though. Cancer treatment and survival has come a long way. The consultant said that 10-15 years ago he wouldn't have been able to treat my mum. There are lots of people on here who have lived with cancer for years. Always have hope and don't let cancer win. 

Thank you for your reply. Your completely right and I'm aware I haven't had a diagnosis yet so my worries are very much speculative. I'm so sorry to hear about your mum, it must be such a difficult time. Lots of love and good vibes to you x
