几百年来，人们对肿瘤缺乏足够的认识，进入21世纪，小儿恶性肿瘤才得到重视。近年来，小儿肿瘤在社会上影响很大。小儿肿瘤要做到早发现、早根除，需要患儿看护人的全面参与。通过介绍小儿恶性肿瘤四级防控战略，阐述了妈妈参与小儿恶性肿瘤的必要性与具体方法，提倡将妈妈培训成最基层的儿科医学人才。

Children's tumors have a great impact on society. Pediatric tumors can be identified and eradicated early, only with a full participation of children's caregivers. This paper discusses the four level prevention and control strategy of the children's malignant tumor, with an emphasis on the necessity and the specific methods of the mother's participation in diagnosis of the malignant tumor of children. We suggest a training of mothers by the most grass-root paediatric medical personnel.
