Enjoy the good news, take a vacation from the cancer war. My mother used to tell me not to "borrow trouble" it will probably find you soon enough. I stopped reading and just enjoy the good days when they come.
I know it is hard not to worry, believe me, but we have to take each good day we are given and make the most of it. This is good news for your husband. Ron has a scan in May, hoping for the same results.
God Bless
