Stomach cancer can be regulated by traditional Chinese medicine, but it needs to be combined with other treatments to achieve better therapeutic effect. Stomach cancer is a cancerous disease that occurs in the stomach and epigastric region, which is mainly manifested by progressive stomach and epigastric pain, poor appetite, emaciation, blood in the stool and hard lump in the epigastric region. Stomach cancer can be classified into spleen and stomach weakness, liver and stomach disharmony, stomach heat and yin, phlegm and dampness obstruction of stomach and so on. Clinically, weak spleen and stomach can be treated by adding or subtracting Sen Ling Bai Zhu San, disharmony between liver and stomach can be treated by adding or subtracting Chai Hu Shuo Liver San and Xuan Fu Dai Ochre Stone Soup, gastric heat injuring yin can be treated by adding or subtracting Jade Maiden Decoction, and phlegm-dampness obstruction of stomach can be treated by adding or subtracting Kailu Er Chen Tang. It should be noted that traditional Chinese medicine can be used as auxiliary treatment for stomach cancer, but it cannot be the only treatment. It is suggested that stomach cancer patients should take standardized treatment under the guidance of doctors.
