When children have tumors, they may have corresponding symptoms in skin, lymph nodes, five senses and nerves. Parents should pay more attention to observe the abnormal symptoms of children in order to achieve early detection, early diagnosis and early treatment of pediatric tumors. The following symptoms in children should be paid extra attention: 1. Poorly compensated anemia or bleeding with unexplained pallor, often accompanied by lethargy, weakness and loss of appetite, or unexplained bleeding, including gum bleeding, nasal bleeding, bleeding spots or petechiae on the skin, which can be ruled out by laboratory tests, such as leukemia. Tumor anemia is different from dystrophic anemia. The latter can be basically improved after proper supplementation of raw materials required for hematopoiesis, such as iron, vitamins and proteins,. In the former case, without regular chemotherapy, even if you take more nutritional supplements, it will be “sinking in stone” and futile. 2, persistent low fever general cold, pneumonia fever, a few days will be good. However, if the unexplained fever persists for more than 1 week, especially if the antiviral and antibiotic treatment is ineffective, you can no longer just take medicine at home to deal with it, you should consult a doctor early. This is because it may be the clinical manifestation of malignant tumor. The fever of malignant tumor presents repeated irregular low fever, when the patient’s body temperature is usually below 38℃. We would like to remind you that when recurrent irregular fever occurs, it is better not to use antipyretic drugs at will to avoid masking the disease. It is best to seek medical attention and find out the cause of the disease in a timely manner. 3.Lymph node enlargement caused by various pathogenic microbial infections causing local or systemic lymph node enlargement, if the lymph node enlargement does not go down for a long time and there is no pressure and pain, it should be examined in detail and alerted to the possibility of tumor. 4, unexplained lumps in the neck, armpit, groin, abdomen, back waist and other parts of the pediatric population, once the lumps are found, the cause must be identified. Lymph node enlargement in leukemia usually does not cause pain, but the more benign “painless lumps” seem to be, the more alert you should be. Parents are advised to touch their children’s whole body after they go to sleep, and once they feel bumps or hard lumps, they should be alert to the possibility of tumor. 5.Abnormal enlargement of limbs and trunk Some bone cancers or rhabdomyosarcoma take enlargement of limbs or trunk as signs, so don’t treat them as trauma and handle them hastily. 6.Unexplained pain, such as headache, abdominal pain, joint pain, etc., is persistent or intermittent for a longer period of time, while neurological symptoms, such as vomiting, unstable walking, etc., often appear. Bone pain is mainly vague and distending, mostly occurring in the sternum and extremity bones. Most of the joint pains are wandering and appear from time to time, which can be easily misdiagnosed as acute rheumatoid arthritis. 7. Abdominal distension and vomiting intestinal tumor may cause intestinal obstruction, resulting in abdominal distension, vomiting and other gastrointestinal symptoms. In addition, don’t take it lightly when your child yells about belly pain, or when the stomach is bloated and bulging; usually when changing clothes and taking a bath, you may want to observe your child’s stomach more and press it with your hand to see if there are any abnormalities. 8, eye abnormalities or discomfort toddlers’ eyes produce abnormal reflected light to light, deep eyes, visible white objects, or eye discomfort such as forward bulging eyes and eye pain. They should go to the eye examination quickly. As with adult tumors, early detection of disease clues is crucial to cure the disease so that treatment time can be bought and efficacy ensured. Therefore, parents should do the following: First look, pay attention to the changes in the child’s mobility, such as loss of appetite, depression, etc. Second touch, usually give the child a bath and feel more often whether there are lumps on the child’s body, especially whether there are changes in the abdomen and body shape and whether any abnormal lumps appear. Third listen, pay attention to the child’s complaints. Young children who can’t speak will cry especially hard or be particularly unhinged because of the lesions; children who can speak will tell their parents where they are uncomfortable. Once the above abnormalities are found, neither should we be hasty nor should we take it lightly. You should go to the hospital and undergo the necessary tests in order not to miss the disease and cause lifelong regrets.
