Smoking is considered as a leading factor that causes cancer.

Cancer is a type of disease that can also be inherited. It is said that in some cases, it can be removed, but with the slightest chance of it remaining in our system, it can relapse too.

Coming back to the answer, smoking in other words, boosts the speed of cancer growing inside ones body.

Tobacco contains chemicals that often cause problems inside our body which are irrepairable.

I hope this answer helps!😊
