My grandfather was diagnosed of lung cancer 4th stage. The doctor said he can live up to 1 year if he will undergo chemotherapy. To think, for 28 years, I never saw my grandfather smoking. He told me that he was smoking when he was young. But he decided to stop.
Now, my worry is my husband. He doesn’t want to stop smoking. I suggest to try electronic cigarette. I think it is safer since it doesn’t contain nicotine. I hope he will stop before it’s too late.
