Story summary
- Genetic variation influences cancer risk through single nucleotide polymorphisms (SNPs), including rs3020449 in the ESR2 gene.
- A study in Bangladeshi women found rs3020449 associated with reduced breast cancer risk.
- SNP outcomes vary across populations, reflecting environmental factors and genetic diversity.
- This is the first study of rs3020449 and breast cancer in Bangladeshi women, signaling need for further research.
