8q24 — prostate cancer risk locus
One copy of the 8q24 prostate cancer risk allele.
You have one copy of a common DNA change in a region of chromosome 8 linked to slightly higher prostate cancer risk.
A small lifetime increase in prostate cancer risk. The effect is real but modest, and PSA-driven screening decisions remain the primary lever.
Your lifetime prostate cancer risk is slightly above average. The effect is real but small, and standard PSA-based screening decisions still do the heavy lifting.
What this means
The 8q24 region contains some of the most replicated common variants for prostate cancer risk, identified across GWAS studies in multiple populations. Effects per allele are small (odds ratios near 1.2), but the region tags a real signal. As with most cancer-risk SNPs, lifestyle and family history are stronger predictors than any single common variant.
This stretch of chromosome 8 holds some of the most reliably replicated common DNA changes linked to prostate cancer. Each copy of the risk version nudges your odds up by about 20%, which is real but small. The signal has held up across many large studies and several ancestry groups. As with most common-variant findings, your family history and lifestyle matter more than any one of these on its own.
Caveats
- Effect size is small per allele; this is a nudge in the prior, not a verdict.
- Polygenic risk scores combining many variants are more useful than any single one.
- Most common in European populations; effects vary across ancestry groups.
