Introduction

Currently, there is insufficient evidence to suggest that children with autism are more likely to develop leukemia than typical children. It is important to avoid exposing children to harmful chemicals such as formaldehyde and benzene in daily life, and to keep them away from environments with radiation. Ensure a balanced diet rich in protein and vitamins to strengthen the body's immunity. Encourage regular sleep patterns and appropriate outdoor activities to improve overall physical health.

Currently, there is insufficient evidence to suggest that children with autism are at a higher risk of developing leukemia than the general pediatric population. A detailed analysis is as follows:

Autism is a neurodevelopmental disorder whose onset is associated with genetic and neurobiological factors; leukemia, on the other hand, is a malignant disorder of the hematopoietic system, primarily triggered by genetic susceptibility, environmental radiation, and exposure to certain chemicals. The underlying mechanisms of these two conditions are entirely different. Current medical research has not identified any direct link between autism and leukemia, and the risk of leukemia in children with autism does not significantly differ from that in typically developing children.

In daily life, it is important to avoid exposing children to harmful chemical substances such as formaldehyde and benzene, and to keep them away from environments with radiation. Ensure a balanced diet rich in protein and vitamins to strengthen the body's immunity. Encourage regular sleep patterns and appropriate outdoor activities to improve overall physical health. Conduct routine health check-ups, monitor indicators such as complete blood count, and pay attention to the child’s emotional and behavioral status. If symptoms such as unexplained fever, bleeding, or fatigue occur, seek immediate medical evaluation.

What should I do if a child with autism doesn't allow physical touch?

Autism spectrum children's aversion to being touched can be improved by respecting the child's personal space, gradually introducing physical contact, and building a reliable, trusting relationship. Parents can also try different forms of physical touch and seek professional support if difficulties persist. It is important for caregivers to understand the child's feelings and needs in order to help them become more comfortable with physical contact, promote emotional connection, and strengthen interaction and communication with their child.
