How would Cigarette Smoking cause cancer to develop in the lungs?

Answer 1

my grandma smoked till 80 some years old. she didn't get lung cancer.

Answer 2

It causes it by being carcinogenic. The smoke can mutate your cells, doing something doctors call deletion, addition, or substitution mutations. Most mutations will not do anything, but there is always that chance that the mutation will affect your cells so that they don't know when to stop growing. They then form a tumor, which can be benign or malignant. Since you are taking the smoke into your lungs, it can cause lung cancer. It can also cause throat or mouth cancer, considering the smoke is there too. Try not to smoke, only one cigarette has the ability to cause that one mutation...

Answer 3

just like the other poster said..Its a carcinogen and it essentially injects bad chemicals into cells which can effect normal replication. The cells begin to divide abnormally and usually more rapidly, causing a tumor, which may or may not be cancerous, but why risk it. Don't smoke. Don't listen to these people who say my father smoked fo 100 years and didn't get cancer..they are an exception to the rule. Most smokers get something...resp problems, emphysems, heart problems, cancer etc... the few who get nothing are rare, and a lot of them do get cancer, its just that old age actually kills them first and no autopsy is done to show that they did in fact have cancer. They just got lucky...

Answer 4

because the smoke has toxins in it that causes cellular damage right where the smokes goes.... TO YOUR LUNGS.
