Why does smoking increase the risk of colon cancer?

Quitting smoking reduces the risk of developing colon cancer

The birth and death of cells in the body occurs continuously. This is a normal process that allows the body to repair and replace damaged cells, thus recovering from disease.

A cigarette contains more than 600 ingredients, 4,000 chemicals, and 50 cancer-causing agents. Carcinogens in cigarette smoke damage cells in the body, and over time the body loses the ability to repair them. As cell damage increases, and the body's ability to repair damaged cells decreases, the risk of cancer increases.

Why is smoking directly linked to colon cancer?

Inhaling the chemicals and toxins causes free radicals to damage DNA and mutations to appear in cells. Free radicals can cause the development of precancerous polyps in the large intestine, which can become cancerous and eventually cause colon cancer. Smoking has also been linked to an increased risk of a more aggressive type of polyp known as a flat adenoma.

Not only are smokers at higher risk of developing colon cancer, they are also at higher risk of dying from the disease.
