ZOOMING IN ON CANCER GENES
"Now, a new study of over twelve hundred people has identified three hundred and twenty genes that are affected by smoking"

Our genetic instructions are finely balanced, and extremely sensitive to any changes and fluctuations within the cell. Some of our genes are "switched on", and others are "switched off". Environmental events (for example smoking or stress), may influence which of our genes are switched on and off. When our genes are switched on they are being expressed, and conversely, when they are switched off they are not being expressed - hence the term genetic expression. I strongly urge you to read the reference article by Drs Niesel and Herzog at the aforementioned link.
According to the department of epidemiology at the American Cancer Society, when predicting cancer risk, the length of time a person has smoked is more significant than the number of cigarettes smoked. According to Cancer Research
Targeted cancer therapies involve the use of drugs (or other substances), that are able to halt the growth and proliferation of cancer. These therapies that are used in specific cancers include drugs which: interfere with both cell growth signalling and tumor blood vessel development; and encourage cancer cell death. They prompt the immune system to destroy targeted cancer cells, and send them toxic drugs.
