儿童也会得肿瘤，学会这两种自查方法帮助及早发现

Core Viewpoint - The article emphasizes the importance of early detection and prevention of childhood tumors, highlighting unique characteristics of pediatric tumors compared to adult tumors, and providing methods for parents to identify potential symptoms in children [1][3][4]. Group 1: Characteristics of Childhood Tumors - Childhood tumors are primarily classified into hematological tumors and solid tumors, with hematological tumors affecting the lymphatic and blood systems, such as leukemia and lymphoma [2]. - Solid tumors can occur in various organs and tissues, including neuroblastoma, nephroblastoma, and retinoblastoma, and are often linked to genetic mutations and environmental factors [2][3]. - The mechanisms, types, treatment methods, and prognoses of childhood tumors differ significantly from those of adult tumors, which are mainly epithelial in origin [3]. Group 2: Early Detection Methods - Parents can utilize the "self-examination methods" such as the "bathing self-check method" and the "sleeping belly button method" to help detect potential tumors in children [5]. - The bathing self-check method involves parents checking their child's body while bathing, ensuring to cover all areas systematically to identify any unusual lumps or signs [5]. - The sleeping belly button method allows parents to feel for any abnormal growths in the abdomen while the child is asleep, which can indicate the presence of tumors [5]. Group 3: Symptoms and Warning Signs - Early symptoms of childhood tumors can be diverse and may include persistent fever, pallor, vomiting, abdominal pain, and unusual lumps [4][6]. - Specific symptoms may also indicate particular types of tumors, such as "cat's eye sign" for retinoblastoma and "panda eyes" for neuroblastoma [4]. - Parents are advised to seek medical attention if their child exhibits unexplained symptoms such as persistent pain or changes in behavior [6]. Group 4: Prevention Strategies - Prevention of childhood tumors should begin during pregnancy, with recommendations for expectant mothers to avoid exposure to harmful substances and maintain a healthy lifestyle [8]. - Regular health check-ups for children are crucial for early detection, as many tumors are not identified until they reach advanced stages [8]. - Genetic counseling and testing are recommended for families with a history of hereditary tumors to assess risks for future children [8].
