Jaanika,

You know, the most important thing that all three of my husband's dr.'s said is that he can NEVER start smoking again. The problem is that smoking changes the DNA in one's oral cavity,(for one)along with everywhere else. With having had cancer, he will always be suseptable to another cancer, and smoking will just multiply his chances of getting it back again. He probably feels, what-the-heck, I have it, so why stop now when it is going to get me anyway. This may sound crude to you, but as someone who smoked for most of my life, I fully understand how he is feeling. I will pray for you and your Dad.
