“How can my child get a tumor at such a young age?” This is the first reaction of many people who are told that their child has been diagnosed with malignant tumor. The answer is yes, with the decrease of mortality rate of infectious diseases and the increase of cure rate of congenital diseases, pediatric malignant tumor has become the main cause of pediatric death (2nd place), only early detection and regular treatment is the key to improve the cure rate. In order to achieve early detection, we must first understand the characteristics and causes of childhood tumors. Most of them are congenital and originate from embryonic tissues. 2. Benign tumors are more common than malignant tumors. The age of onset of malignant tumors is a double-peak trend. 35-50% of the tumors develop within 3 years of age and are mostly embryonic tumors, and the other peak is pre-puberty, mostly hepatocellular liver cancer, thyroid tumor, osteosarcoma, etc. 4, malignant tumor site is deeper and difficult to find 80% are late. 5.No effective census method VMAAFPB ultrasound. 6.The general public have misconceptions and give up treatment because they think it is an incurable disease, thus losing the opportunity to get cured. In fact, children are more sensitive to drug treatment and tolerate chemotherapy very well, some even less than adults due to bone marrow suppression, infection and reduced dose intensity affecting the efficacy, the overall cure rate of children’s tumor can reach more than 70%. Causes of childhood tumors 1. embryonic developmental disorders; 2. genetic factors; 3. susceptible cancer-causing factors such as EBV infection, nuclear radiation, some pesticides and some chemical substances. Early detection of pediatric tumors Pediatric tumors often do not show any obvious abnormalities in the early stage, so parents and medical personnel need to observe patiently and carefully: 1. Therefore, when your child is sleeping, bathing or changing clothes, you should often feel your child’s stomach, and if you find any abnormality, you should consult a doctor in time for further examination. More than 50% of children can find small lumps on both sides of the neck, behind the occiput, behind the ear or in the armpits on both sides, most of them are enlarged lymph nodes, which are the immune organs of the human body and will swell when they are invaded by bacteria, viruses and tumors. However, if the lumps are in bunches, growing in blocks, hard and painless with light pressure, we should pay high attention to them. 3. abnormal performance: enlarged breasts and vaginal bleeding in little girls (before 6-7 years old) and enlarged breasts in boys indicate problems with hormone levels, which may be tumors of pituitary gland, adrenal gland or ovaries. Most children’s leg pains are growing pains, but a few of them are caused by retroperitoneal tumor compressing nerves, which is a deeper location and difficult to find. The tumor in the pelvic cavity compresses the rectum and shows difficulty in defecation. 6.Weakness and pale face are often the manifestations of advanced malignant tumor. 7. Unexplained fever, especially fever that is not treated by antiviral or antimicrobial therapy, should be alerted to the possibility of malignant tumor. 8.Unexplained bleeding includes gum bleeding, skin bleeding spots or bruises, etc. 9.Long-term persistent or intermittent pain (headache, abdominal pain, joint pain, etc.); 10.Regular physical examination is necessary for children whose tumors are more than 50% congenital, so it is necessary to have a physical examination within 3 months of birth, which must include abdominal ultrasound, and then 1 physical examination every year. 11. When there is suspicion, timely B ultrasound, CT, MRI and other examinations, and if necessary, invasive examinations (puncture, biopsy, etc.) are feasible to help children’s tumor early diagnosis. Therefore, parents’ careful observation of children or regular health check-ups in children’s hospitals are crucial to the early detection of malignant tumors in children. The causes of tumors are many, such as environmental deterioration, radiation from home appliances, changes in children’s living habits and recipes of high protein and high fat. Especially, the harm caused by food pollution, especially nitrite, aflatoxin, pesticides and heavy metals such as lead, mercury and cadmium are to blame. Residual pesticides in food sneak into the body and accumulate down, light damage to the liver, brain, kidneys and other organs, serious acute poisoning and death. In addition, the best tonic for children is a normal diet, under normal circumstances do not need to take supplements, eat less foreign fast food, sweets, acidic food, instant noodles, chocolate, coffee, dried fish fillets, cold drinks and so on.
