How Is Smoking Responsible for Colorectal Cancer?

Smoking contributes to colorectal cancer by introducing harmful chemicals that damage the DNA of cells in the colon and rectum. These carcinogens cause mutations that disrupt normal cell growth and repair, leading to the development of cancerous tumors.
