The hot and humid climate in the winter makes food spoil and moldy, and aflatoxin in moldy food is an important cause of liver cancer. Therefore, it is recommended to pay attention to dietary hygiene and promote regular checkups for high-risk groups for early detection, early diagnosis and early treatment. For the treatment of liver cancer, it is recommended to adopt sequential, combined and systematic comprehensive treatment and to develop individualized treatment plans according to patients’ conditions. The high temperature and humid climate provides a convenient environment for the growth of pathogenic microorganisms after entering the ambient weather. Therefore, in the summer, especially in volcanic days, bacteria and other breeding faster, fruits and vegetables or food, etc. are easy to mold, rot and deterioration. The humid environment of volcano is easy to breed mold, especially peanuts, corn, rice and other food is easy to mold and produce aflatoxin, this toxin is an important cause of liver cancer. Therefore, Director Su reminded that special attention should be paid to dietary hygiene in volcanic days, don’t eat moldy food, throw away fruits even if they are partially rotten, and don’t drink unhygienic ditch and pond water to avoid ingesting carcinogenic substances and other harmful substances that may cause diseases from the mouth. The high incidence of liver cancer in China is related to the high incidence of hepatitis B and C. In recent years, cases related to alcoholic liver disease and drug-related liver disease are on the rise. Director Su pointed out that heavy liver cancer can have symptoms and signs such as jaundice, ascites, enlarged liver, hardened liver, uneven surface, swelling and tingling in liver area, but early symptoms and signs are not obvious, some patients may have symptoms similar to chronic hepatitis such as weakness, mental discomfort, fatigue, etc. Some patients are already in heavy condition without any uncomfortable symptoms, and the onset is more insidious, which is the reason for late detection of liver cancer, aggressive disease and poor prognosis. This is an important reason for late detection, dangerous disease and poor prognosis of liver cancer. Therefore, in order to achieve early detection, diagnosis and treatment of liver cancer, patients should be consciously examined regularly. Especially, patients with viral hepatitis or other chronic liver diseases are at high risk of developing liver cancer and should pay more attention to regular checkups. It is recommended that high-risk groups should be screened every three to six months for ultrasound, methemoglobin and other liver cancer serum markers, etc. Once problems are detected, further examinations should be conducted to determine the diagnosis for early treatment, and early treatment is very effective, even to the extent that it can be cured. Director Su said that with the improvement of medical level, there are several methods for early diagnosis of liver cancer. For example, the most common imaging examinations, including ultrasound, CT, MRI, etc., are helpful to detect tiny occupations in the liver. The application of ultrasonography is a leap forward and a milestone in ultrasound diagnostic technology, which has significantly improved the sensitivity and accuracy of liver cancer diagnosis and can help to detect lesions smaller than 2 cm. It is the “gold standard” for liver cancer diagnosis, which is to puncture liver nodules under ultrasound or CT guidance and find cancer cells under microscopic pathological examination. It has the unique advantage of integrating diagnosis and treatment into one and solving the problem at one time. Once hepatocellular carcinoma is diagnosed, it should be treated as early as possible, and early treatment can greatly improve the treatment effect. Director Su pointed out that on the basis of individualized and standardized treatment, “sequential, combined and systematic” are the key words of liver cancer treatment. By sequential, it means to adopt different treatment methods according to certain order, such as surgery first and then intervention, or intervention first and then radiofrequency, etc.; by combined, it means to take into account patients’ original diseases such as liver disease and kidney disease while treating tumor; in addition, it advocates humanistic care of disease treatment, i.e. systematization of treatment, from treatment to drug supply and technical support, not only focusing on treatment of liver cancer itself, but also on patient’s liver preservation and psychological health. In addition, we advocate the humanistic care of disease treatment, that is, the treatment systemization, from treatment to drug supply and technical support, not only focus on the treatment of liver cancer itself, but also pay attention to the comprehensive situation of liver preservation and mental health of patients. In addition, liver cancer is a systemic disease, involving medical, surgical, interventional and other disciplines, so integrated multidisciplinary treatment is also very important. Under the guidance of doctors, it is very important for liver cancer patients to adhere to individualized and multidisciplinary comprehensive treatment in the summer; at the same time, reasonable health care plays an important role in disease recovery. Director Su pointed out that besides regular review, liver cancer patients must pay attention to happy mood and proper rest. In terms of diet, besides paying attention to dietary hygiene, not eating moldy food and not drinking unclean water, Director Su reminded that in summer, due to the hot weather, the body consumes more, and liver cancer patients consume more due to their poor appetite, so they should pay special attention to nutrition in summer. However, paying attention to nutrition does not mean that we should rely on health food, but we should start from daily diet and choose soft, light and easily digestible foods rich in nutrients, such as eggs, milk, fresh vegetables, mushrooms, barley and yam, which are high in protein and vitamins. To ensure that you eat fresh vegetables every day, half of which should be green leafy vegetables; milk or yogurt can be used as a supplement to high quality protein; porridge is easy to digest and advocate eating more; at the same time, avoid eating hard, rough, sticky or spicy stimulating diet, such as dry and hard burritos, crispy bones, rice cakes, spicy hot and barbecue are not suitable for consumption.
