Hi rugelyboy. I'm so sorry to hear that your MIL has mouth cancer. I have not been through this, but have been through bone cancer which spread to other tissues in my body. I guess I am one of life's survivors in that I won my fight against cancer. Many people do, but we tend not to hear about them as much as those who don't, as in the eyes of the press, positive stories are not as interesting as negative ones. I just wanted to wish your MIL much success with her treatment and you and your wife the courage and strength to help her through this. Cancer treatement is advancing all the time and it is no longer as scary as it used to be. Try to stay positive and hopeful and you will be helping your MIL to stay the same . Best wishes. :o)
