Almost all cases of lung cancer are from smoking, but just because some don't get cancer after smoking, they are still far from healthy. Most long-term smokers have emphysema or bronchitis and even some people in their 30's have irreversible lung damage. There is no way to win health-wise if you smoke. You can be sure that anyone who smokes is not 100% healthy.

Just like there are people blessed with athletic genes, there are people that are blessed with cancer resistant genes. Just like there are people that seem to eat and eat and never get fat. There are also people that are prone to getting cancer easier that other and they don't even smoke.

Cancer is a disease that can effect anyone. For example breast cancer is also found in men. Genetic factors play a very large part as to whether you will get any type of cancer. Very similar to alcohol and drug addictions. Some people are more genetically inclined to become addicted than others. After genetics, how you treat your body also effects whether "rouge" cells turn into cancer. In the case of lung cancer, smoking greatly increases the chance of cancer cells forming but not always. My grandmother had lung cancer and she never smoked or lived in a house where someone did smoke.

We really don't know why people get cancer. The theory is that somehow foreign materials irritate tissue, and from that, one can get cancer, and that is a good fit for lung cancer, but it certainly doesn't explain why other cancers happen, such as pancreatic, liver, brain, ovarian, etc. We have shown that tendency to get cancer is partly inherited. The most famous example is Jimmy Carter's father and sisters, who all got pancreatic cancer, and died from it, while he somehow was spared. There are genetic markers now being identified for different cancers. We can show that certain people who have certain genes will have a dramatically higher risk of cancer. The number of smokers who actually get lung cancer, while very significant, is still not so large as to guarantee that if you smoke, you will get cancer. Some people smoke all their life and never have a problem. Presumably their genes had some protection somehow. Others will get cancer, and there's no reason we can find. They had a high vulnerability.

I knew a woman who never smoked a cigarette in her life that got lung cancer and passed away. I think cancer hits anyone it wants and settles down in the body wherever is most comfortable for it to grow unnoticed until it's too late to do anything about it. It doesn't matter if a person is rich or poor. Cancer doesn't seem to discriminate. They say it's all the genes.
