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].

Core Viewpoint - The event aims to promote cancer prevention and treatment awareness, encouraging early screening and standardized treatment for patients [1][2] Group 1: Event Overview - The event is part of the 31st National Cancer Prevention Week, held from April 15 to 21, 2025, with the theme "Scientific Cancer Prevention, Healthy Living" [1] - Over 50 experts from 20 cancer-related departments provided free consultations and authoritative answers to patients [1] Group 2: Importance of Early Detection - Early detection and timely treatment are emphasized as critical for various cancer diseases, with delays leading to increased treatment costs and reduced efficacy [2] - The initiative aims to enhance public awareness of early cancer screening to prevent late-stage diagnoses [2] Group 3: Collaborative Efforts - The collaboration between the two hospitals has resulted in 143 advanced diagnostic and treatment technologies over three years, with 85 regionally leading and 58 nationally leading technologies [2] - This partnership has significantly improved cancer treatment levels in the Liaoning region and accelerated the transformation of research achievements into practical applications [2]
