Definitely do not go into too much despair until you get into staging as treatment has evolved greatly over the past two decades. Even in Stage 4 survival rates have been consistently over 50% but if early you may be able to have alternate treatment that is higher with less toxicity. There is a significant amount of data and reason for hope that this is just a huge speed bump. There are many others cancers that is not the case but with some faith and love this to shall pass.
