Almost all patients with gastric cancer will have a similar phenomenon, but the degree is different. From a medical point of view, this is caused by the side effects of chemotherapy. Chemical drugs are not selective in tumor treatment and will not specifically target the cancer stage. Therefore, at the same time of chemotherapy, it will inevitably cause damage to other normal cells, such as gastrointestinal cells, vomiting, loss of appetite, bone marrow cells, etc., resulting in leukopenia, and chemotherapy cannot continue.

In terms of diet, we should eat light, low-oil, high-protein and low-fat foods such as vegetables, fruits and lean meat during chemotherapy. Diet is only a necessary measure for daily care. In order to reduce the side effects of chemotherapy in essence, we should also take professional anti-chemotherapy drugs, such as Ganoderma lucidum. The modern pharmacological research of Ganoderma lucidum shows that, firstly, Ganoderma lucidum enhances its anti-tumor ability, and its polysaccharide components enhance the function of various immune cells to kill tumor cells, or promote immune cells to secrete hormones to inhibit tumor growth and make it apoptosis. Secondly, Ganoderma lucidum cooperates with radiotherapy and chemotherapy to achieve the effect of "increasing efficiency and reducing toxicity". For example, the contents of effective components such as polysaccharides and triterpenoids in medical grade Ganoderma lucidum preparations are greatly increased, which can reverse the multidrug resistance of tumor cells, improve the tumor killing effect of anti-tumor drugs, and even greatly reduce the dosage of chemotherapy drugs; Ganoderma lucidum combined with radiotherapy and chemotherapy can not only have synergistic effect, but also significantly reduce the side effects of radiotherapy and chemotherapy. Ganoderma lucidum can effectively weaken the invasion, migration and metastasis of cancer cells by improving the immune system function, enhancing its recognition and killing ability, which is more conducive to the control of the disease after treatment.
