Liver cancer is divided into two main pathological types, the first being hepatocellular carcinoma, which is the most common, and the other being cholangiocellular carcinoma. Clinically, vomiting is also a common symptom of liver cancer. For symptomatic treatment, we can provide gastric protection and administer antiemetic drugs such as stomach comfort, but these are only symptomatic treatments and do not cure the root cause. The key is still to treat the liver cancer itself, as the symptoms will only alleviate once the cancer is under control. For advanced hepatocellular carcinoma, targeted therapies like sorafenib are available. If it is cholangiocellular carcinoma, and symptoms like vomiting and jaundice appear, which may be obstructive symptoms, then a surgical procedure in hepato-biliary surgery to drain the bile can be performed, which can also alleviate the symptoms of vomiting. (Medications should be used under the guidance of a doctor.)
