Problems solved by technology

Chemotherapy is a treatment method that uses chemical drugs to kill tumor cells, inhibit the growth and reproduction of tumor cells, and promote the differentiation of tumor cells. Almost all chemotherapy drugs can cause liver function damage, and abnormal liver function may occur in mild cases. Discomfort in the liver area occurs, and even can lead to toxic hepatitis; high doses of some chemotherapy drugs can cause renal function damage, resulting in low back pain, discomfort in the kidney area, etc., and due to the poor selectivity of chemotherapy drugs, while killing tumor cells, Normal cells and immune cells are also killed in large quantities, and the side effects and toxic effects are extremely great
