Hi, Two years ago I had Stage 4 cancer, I had about 3 inches of jaw removed, lining of mouth, lymph nodes(a moderate), and a very small piece of tongue. I had the same type of operation, mine failed. If your Mom is home and well, she is lucky because her flap is good. My only problem is because they are still trying to replace my jaw better than it is.The leg is great, after I got stronger I started to walk on it, and it got even stronger. By walk I mean exercise walk, a mile a day or so. It does take awhile to recoup, your bady has been through a lot. Later she will learn to eat again, it will be slow at first but gets better. My tumor was big, but they got it all and I have been cancer free for two years. My Dr. says the longer it's cancer free, the less likely to come back. I hope you consider this the good. She has been through the bad part, each day and week will only get better. Good Luck. gnelson
