Cancer that starts in your liver is called primary liver cancer. About 1,800 people are diagnosed with liver cancer each year in HK.
Cancerous tumours can grow through your liver and spread to other areas of your body, through your bloodstream or your lymphatic system, where they may grow and form secondary tumours. Your lymphatic system is the tissues and organs, including your bone marrow, spleen, thymus and lymph nodes, that produce and store cells that fight infection and disease. This spread of cancer is called metastasis.
Tumours may also spread from other parts of your body, such as from your bowel, breast or lungs, to your liver - this is called secondary liver cancer. Secondary liver cancer is much more common than primary liver cancer.
