A new study reveals that some children develop cancer due to auto-antibodies targeting DNA repair mechanisms, offering fresh insights into pediatric cancer origins.
Cancer linked to aging and genetic mutations
Cancer is typically associated with aging because, as people grow older, genetic mutations accumulate in cells. These mutations can cause cells to lose control of their normal functions and become harmful.Pediatric cancers are rare and hard to explain
Pediatric cancers account for less than 2 percent of all cancers in high-income countries. Most of these cancers in children are not caused by genetic mutations inherited from parents, making their origins difficult to determine.New research offers possible explanation
Researchers from the University of Bergen in Norway may have uncovered a reason for early-onset cancers. In a study published on October 14, 2026, in the journal Frontiers in Immunology, they found that children with cancer often have auto-antibodies that target their own bodies.Auto-antibodies may disrupt DNA repair
These auto-antibodies can interfere with the body's mechanisms for repairing DNA. This disruption could lead to a rapid accumulation of genetic mutations, increasing the risk of cancer development in children.Discovery begins with prior observations
The discovery started with an earlier observation: in cancer patients, genetic mutations can change proteins so that the body no longer recognizes them. This leads the immune system to attack these altered proteins with antibodies. However, these antibodies may sometimes mistakenly target the normal, non-mutated versions of the same proteins.
