Autism and cancer risk.
Autism and cancer genes overlap, so keep medical history on your radar and advocate for routine screenings.
01Research in Context
What this study did
B (2011) wrote a narrative review. The author looked at genetics studies and cancer data. The goal was to see if autism and cancer risk are linked.
The paper pulls together early clues from two fields: oncology and developmental disability.
What they found
The review says autism genes and cancer genes overlap. This hints that cancer risk might differ in people with autism.
No hard numbers are given. The paper calls for big epidemiology studies to test the idea.
How this fits with other research
Nijhof et al. (2025) extends the story. They counted real hospital charts and found autistic adults get sicker from COVID-19. This shows the autism-medical-risk link is more than theory.
Robison (2019) also extends the picture. That review looked at adults over 50 and found higher death rates and more medical problems. Together the three papers build a timeline: possible risk in 2011, confirmed poor outcomes in 2019 and 2025.
Zeidan et al. (2022) gives the backdrop. Their big number — about 1 % of people worldwide have autism — means any raised cancer risk would affect millions.
Why it matters
You may not treat cancer, but you do track client health. Ask about family cancer history during intake. When you write medical referrals, flag that autistic people can face extra risks. Push for regular screenings just like Dewy et al. did with COVID shots. One sentence in a report can start the screening conversation sooner.

03Original abstract
A literature review was conducted on the genetic and developmental bases of autism in relation to genes and pathways associated with cancer risk. Convergent lines of evidence from four types of analysis: (1) recent theoretical studies on the causes of autism, (2) epidemiological studies, (3) genetic analyses linking autism with mutations in tumor suppressor genes and other cancer-associated genes and pathways, and (4) contrasts with schizophrenia, Parkinson's, and Alzheimer's disease indicate that autism may involve altered cancer risk. This evidence should motivate further epidemiological studies, and it provides useful insights into the nature of the genetic, epigenetic, and environmental factors underlying the etiologies of autism, other neurological conditions, and carcinogenesis.
