Itching is another sign that the person may be suffering from liver cancer. Sometimes it is not that simple to explain why the whole body starts itching. It is said that the tumor might be releasing toxins which get into your blood and then spread all over the body. This causes the itching. Some cancers do not cause any itching. However, there’re lots of cases when patients suffer from severe itching. If your liver does not function right, your blood might contain too much bile. Appropriate treatment is needed in order to calm down the itching.
