Answer 1

Enviromental factors and lifestyle such as smoking, tobacco and radiation affect the risk of cancer. If you are living in a city that has high pollution rates then a person has higher chances to have cancer as the smoke from pollution has carcinogens and that can cause cancer.

The main organ of cancer related to cigarette smoking or tobacco use is mouth and lungs. These particular organs are affected because in case of lung cancer, when a person inhales cigarette smoke, it has many carcinogens and that change in lung tissues immediately and causes rapid growth and causes cancer. Same is the case for tobacco use because as you take tobacco it comes in contact with tissues in mouth and nicotine like stuff that is carcinogenic cause cancer to these organs.
