Doctor's answer (1)
Dr. Qi Zhirong
Advanced liver cancer itself is not contagious. Liver cancer is a malignant tumor that occurs in liver cells, primarily caused by genetic mutations in the liver's own cells, leading to abnormal cell proliferation and the formation of a tumor. These cancer cells originate from the patient's own normal cells undergoing malignant transformation and, unlike infectious pathogens, cannot be transmitted from one person to another. In daily contact with a liver cancer patient, such as sharing meals, hugging, or using the same household items, there is no risk of transmitting liver cancer.
Although advanced liver cancer itself is not contagious, some of the underlying causes of liver cancer, such as infection with the hepatitis B virus (HBV) or hepatitis C virus (HCV), are contagious. Therefore, when coming into contact with liver cancer patients who carry these viruses, precautions should be taken to prevent the spread of the viruses, especially avoiding unnecessary exposure to blood. Patients with advanced liver cancer should ensure adequate rest, avoid staying up late, maintain a positive mindset, and receive encouragement and support from family members. At the same time, family members and caregivers should provide necessary care and support to help improve the patient's quality of life.
