The lymphatic system is the body’s natural defense tissue against infections and toxins, and when the defense system fails, the consequences can be imaginable. In recent years, lymphoma has become one of the fastest growing tumors worldwide, with an average of one new patient every two minutes and over 200,000 deaths per year. Although the overall incidence of lymphoma in China is low, it is noteworthy that lymphoma has a tendency to become younger and has become one of the most common malignancies in children. Lymphoma “prefers” the young and the elderly Lymphoma can develop in all age groups, but in general, lymphoma prefers the young and the elderly, which is related to the developmental process of the human immune system: the immune system of the young is not fully developed, while the immune system of the elderly begins to gradually decline. In terms of clinical tendency, lymphoma is still a disease of the elderly, concentrated in the age of 50 to 60 years, but now there is a trend toward younger age. The onset in teenage children may be related to genetic and environmental factors, such as renovation pollution, or a long history of chronic infections. Lymphoma becomes one of the most common malignant tumors in children At present, the epidemiological survey of lymphoma in childhood in China has not yet begun, but according to the World Health Organization statistics, it is estimated that there are more than 7,000 new cases of lymphoma in children in China every year. Lymphoma in children is extremely malignant and has an extremely fast progression. Lymphoma may progress throughout the body in a week or two, from stage I to stage IV. However, once treated, the effect is also immediate. In one hospital, the overall cure rate has reached 80% among more than six hundred children with lymphoma treated over a ten-year period. A finely stratified treatment plan is the key. That is, lymphoma is finely stratified into different pathological types, different risk levels, and different stages, and then continuously adjusted during treatment. Enlarged lymph nodes in the neck are the most common manifestation of lymphoma in children, but more often than not, the manifestation is very hidden, leading to frequent misdiagnosis and mistreatment in clinical practice and missing the best treatment opportunity. Due to the low awareness of lymphoma in children in primary care hospitals, only statistics show that 50% of children have been misdiagnosed. Lymphoma usually occurs in the abdominal cavity, and the most common manifestation in children is acute abdomen, such as intussusception, recurrent intussusception, or the same manifestation as appendicitis or appendicitis, the onset of which is relatively insidious and not well detected. The cure rate of early lymphoma patients is more than half The treatment of lymphoma in children in China started late and the overall level is low, and the overall cure rate in the country is only about 50%. However, once children’s lymphoma is cured, the long-term recurrence rate is very low and the cure effect is very good. Not only children, but also adults have good results in treating lymphoma without surgery. Due to the continuous improvement and updating of diagnostic techniques and treatment methods, the near-term outcome and long-term survival rates of patients have improved considerably. There are many types of lymphoma, with more than 70 known pathological types, which can be broadly divided into two categories: Hodgkin’s lymphoma and non-Hodgkin’s lymphoma. Among them, non-Hodgkin’s lymphoma develops about 80-90% of all lymphoma patients in China, and is the fastest growing hematologic tumor in terms of incidence. There is no such thing as benign lymphoma, but any lymphoma is definitely malignant and it is not a surgical disease. Lymphoma requires both internists and radiologists to address. For early stage I and II patients, the cure rate is 50% to 60%. As long as it is detected early, can be standardized and accurately diagnosed, patients still have a very high chance of being cured. The early symptoms of lymphoma are not obvious and can be easily ignored by patients. When painless progressive lymph node enlargement of unknown origin occurs, which is ineffective after general anti-inflammatory treatment, one should be alert. If you find swollen lymph nodes with fever, unexplained long-term low-grade fever or periodic fever, or wasting, you should go to a specialist for examination in time. A healthy diet, moderate exercise, freedom from tobacco, and protection from lymphoma Genetic predisposition is a “congenital” factor in the development of lymphoma. If a relative in a person’s family has lymphoma, that person’s risk of developing lymphoma is about two times higher than the average person. Genetic factors are uncontrollable, but what we can control is the “acquired” factors of lymphoma, that is, correcting unhealthy lifestyles. Epidemiological studies have shown that foods high in animal protein, saturated fat, eggs and cream increase the risk of lymphoma, while foods high in fiber, such as tomatoes and cauliflower, can reduce the risk of lymphoma. Therefore, we should eat less fried, smoked, high-fat and high-calorie foods, and eat more fresh vegetables and fruits to match meat and vegetables. Second, moderate exercise is also essential. According to the analysis of relevant data, the risk of lymphoma is 1.35 times higher in smokers, and 1.84 times higher in those who have smoked for more than 20 years, while the incidence of lymphoma is not higher in those who have quit smoking. It is important to note that passive smoking can also lead to an increased risk of lymphoma, with a 2.89-fold increased risk for those who have been passive smokers for more than 40 years. Therefore, for the sake of your health and that of your family, please stay away from tobacco.
