You shouldn't be scared, but you do need to be vigilant, I knew my water works were playing up, wasn't sure why, but got an ultra sound scan and they found the tumour. Now it is a tad un nerving when you get told, even more so when you are told it was level four and aggressive, but it is out, three CT scans later still clear and most importantly, keeping chilled(seems stress makes things worse) and making each day as good as you can. I'm not morbid, not thinking each day could be my last, (that could happen crossing the road), no bucket list, just glad I'm still on the green side of the grass.
