You don ' t know you ' ve lost until it ' s too late to do anything about it . Correct . Which means there is a risk calculation market for this . If you are very risky you can have no fees or very low fees but if you are risk averse you will up it say $. 17 instead of $. 15 . Or just use BitcoinQt and not think about it like I do <| sep |> I ' m sorry that you have gone through this with both your dad and father in law . Unfortunately , it a not uncommon for bladder cancer to spread even with aggressive measures like chemotherapy followed by surgery . I think what likely happened is with the previous scans there were tiny lesions , which were less than 1 cm in size . Because they are so small , it ' s impossible to know whether they are cancer or if they are something completely unrelated because it ' s pretty common for people to have tiny things in their lungs , that ' s completely benign . The only way to know is see if they grow . Because chemo followed by surgery would be the only chance of cure , they were essentially giving him the benefit of the doubt and hoping that the stuff in the lungs were benign .
