From the very beginning, Martin felt that he was bound up with（与……紧紧地在一起）his lovely little patient. One day, following some tests , Betty gave the doctor a big hug（拥抱）.

　　A few months later the doctor removed not only the tumour（肿瘤）, but also the entire lower left side of Betty’s gum（牙龈）and jawbone. Because Betty was so young, Martin was hopeful that her jawbone might regenerate.

Soon she couldn’t even close her mouth, and as her eating problems worsened, Betty ‘s weight dropped from 20 kilos to 15. Martin knew from experience that it might invade the brain.

Morgan noticed that the tumour had begun to change. It was actually becoming smaller! For two months her tumour appeared to be going away for ever. In the coming months, Betty’s tumour continued to appear. She was able to eat solid food once again. Her jawbone was regenerating. The tumour was gone.
