There is no clinical claim that alkaline foods are a dead ringer for cancer cells. There are many alkaline foods, such as kelp, grapes, citrus, pumpkin, tomato, spinach, cabbage and so on. Alkaline food is usually not the nemesis of cancer cells and there is no such claim in the clinic, which should not be blindly believed. It is also worth noting that food does not have special therapeutic properties and cannot achieve the purpose of cancer treatment. When it is clear that there are cancer cells in the body, patients should actively cooperate with doctors through surgical resection, radiation therapy, chemotherapy and targeted therapy to achieve the purpose of killing cancer cells, controlling the disease and improving the quality of life. In daily life, pickled products and spicy stimulating food should be avoided. One should pay attention to the rationality of diet and ensure the balanced intake of nutrients. If there is a history of cancer in the family, regular medical checkups should be conducted to monitor the health condition. If cancer is detected, you should receive standardized treatment in a timely manner to avoid delays.
