By the number of users, the question does smoking cause cancer still seems unclear to many smokers. Bear in mind, so far zero evidence exists that vaping leads to any form of cancer. Though it has yet to be studied in depth, neither the components, the process, nor the liquid seem to contain any of the same harmful ingredients or byproducts as cigarettes.

Smoking tobacco however, causes a long list of diseases including a staggering number of cancers. In fact, the Centers for Disease Control has identified some specific cancers as being directly caused by tobacco smoke. Effectively, by continuing to smoke throughout your life you increase your risk of contracting some variety of cancer.

In fact, health scientists have said that there is virtually no part of the human body that is unaffected by the consumption of tobacco. So it should be no surprise that it can lead to increased risks of cancer affecting so many organs and systems of our bodies. To understand what kinds of risk factors smokers leave themselves open to we’ll go through the different types of cancer and the related likelihood by statistic of risk by continuing to smoke.
