Patients with liver cancer need to quit smoking.
The tar in cigarettes is made up of thousands of chemicals, many of which can cause liver and lung cancer as well as cardiovascular disease. Patients with liver cancer often experience a variety of complications after surgery, most commonly lung infections (pneumonia), and smoking is a common factor in postoperative lung complications.
Long-term smoking can weaken the elasticity of the lungs and can also affect lipid metabolism in the liver.
Also, surveys have shown that the mortality rate among liver cancer patients is much higher among smokers than among nonsmokers. It is clear that, like other cancers, smoking has some kind of deleterious effect on the development of liver cancer.
