Hello again... I am glad you came back to the forum with an update. It is good that your father took you along to his appointment, and I am so sorry to hear the news that was delivered to you both.
Although your doctor was quite blunt, he would be doing you a disservice if he told you chemo would cure or "get rid of" your Dad's cancer. I don't think any reputable doctor would make that claim because it is impossible to know how effective chemo will or won't be for any patient. The important thing to take from that is that it can prolong life for your Dad, and as you put it, so he can get back to the business of living. None of us knows how long that might be for each of us, cancer or not.
We have two wonderful members I am aware of who are currently undergoing chemo and while it is not easy, they are true champions of perseverance and determination. Reading some of their posts, if you haven't already, will let you see how they are coping with chemo, and maybe will give you some inspiration to pass along to your Dad. Their user names are mmc (Mike) who responded to your first post, and jmena (Jean).
Mike started the following thread recently and Jean has posts in there as well. If you want to read more from either, just click on their profiles where you can find their past posts.
Good news and start of cycle 4
