Warning Signs Of Childhood Cancers

Persistent Nausea

Aa child who presents with abnormal and persistent nausea may be affected by cancer as the underlying cause of their symptoms. One of the most common types of childhood cancer known to produce persistent nausea and frequent vomiting is referred to as neuroblastoma, which is a malignancy of the sympathetic nervous system because the tumor can press on parts of the abdomen, chest, or spinal cord that activate the nausea center in the brain. Another form of cancer that develops in children that may produce nausea and vomiting is referred to as Wilms' tumor. Wilms' tumor describes a malignancy that has developed in the kidney of a child that causes reduced kidney function. When the kidneys are unable to filter toxins from the blood of the affected individual properly, they can experience persistent nausea because their brain is attempting to rid the body of the toxic substance. Certain types of brain cancers in a child can compress the part of the brain that contains the nausea center, which can also cause them to feel like they need to vomit.
