The Effects of Second-hand Smoke on Liver Cancer

Abstract

Secondhand tobacco smoke contains at least 69 carcinogens, such as nitrosamines, hydrocarbons, tar, and vinyl chloride. The liver is the main metabolic organ for these products. When the human body is exposed to these carcinogens for a long time, the carcinogens will cause "mutations" in the genes in the body and gradually accumulate, causing the cells to be unable to "function" normally, eventually leading to the occurrence of malignant tumors.Harmful substances such as nicotine in tobacco can activate cytokines and intermediate products of fiber formation, which accelerate the process of liver fibrosis and hinder the recovery of liver function in patients with liver disease. The condition will worsen with the increase in daily smoking, promoting the occurrence of liver cancer.
