smoking cigarettes over a long period of time
smoking a large number of cigarettes each day
not smoking for a year, then starting to smoke again

Answer 1

Smoking cigarettes over a long period of time and smoking a large number of cigarettes each day are factors that increase the risk of lung cancer. Starting to smoke again after a period of not smoking can also increase the risk.

Step-by-step explanation:

Smoking cigarettes over a long period of time and smoking a large number of cigarettes each day are both factors that increase a person's chance of developing lung cancer. This is because cigarettes contain harmful substances that can damage the lungs and lead to the development of cancerous cells. Not smoking for a year and then starting to smoke again can also increase the risk as it exposes the lungs to toxins once more.
