Q&A: 10 cancer-related misconceptions

As China marks 30th "National Anti-Cancer Week" from April 15-21, learn from health experts about cancer-related misconceptions. Common risk factors for suffering from the cancer include hepatitis virus infection, liver cirrhosis, alcoholism, gene mutation, hereditary metabolic disease, smoking, obesity, etc, and the causes have not been fully found. For example, kidney cancer may have no obvious symptoms in the early stage, whereas painless hematuria is the most common symptom of bladder cancer, for which some patients may overlook seeking timely treatment as they mistakenly regarded their symptoms as a common urinary system inflammation. Q: Do patients carrying hepatitis B virus get liver cancer? For patients who are carriers of the hepatitis B virus and have no significant liver changes, the risk of developing liver cancer is relatively low.
