Many of us know just how you feel - I was healthy although older, no history of any kind of cancer in my family, didn't find a lump, just a strange sensation and colour. Knowing where the tumour was didn't help much, still couldn't feel it. Friday it's biopsies,Tuesday it's diagnosis, Friday week it's surgery. Most of my brain trailing weeks after. BUT you get through it. Good medical and family support, support at work if you are able to work through which I did, and some time and opportunity to think and learn about what cancer throws up (not all of it is bad) are important. But so is realising that stuff happens, you weren't expected to see this coming, it just did. I felt cross when a pathologist referred to my "adventure". But he was right. Some adventures are very scary. They sometimes take you places you had rather not be. But if you are lucky, they are also amazing learning curves. Best wishes.
