A friend of the family was diagnosed with throat cancer this year, which is incredibly unusual because he does not smoke and does not drink heavily. It was a total shock to everyone, but practically the whole town was supportive (just about everyone knows his family as he and his wife own Dale's Refrigeration and Heating, the only appliance store in town). He recently found out his cancer came out of remission and is doing another round of chemo.
Cancer...and please pardon my bleeped language...is a b***h. The treatments, running back and forth to the hospital, having to be isolated from anyone who has a cough to avoid getting sick, wondering if the next sneeze you make is a sign the cancer has come back. Its Hell. The best you can do is just be there for her. Anyone going through cancer needs the support. From what you're saying it doesn't sound like she's in the final stages and it would take a miracle for her to beat this...so stay positive that she'll beat this.
