The discussion about changing genes in healthcare brings up important ethical questions. Many people compare this to "playing God," which makes us think deeply about the choices we make.

1. Genetic Testing and Screening:

   • Genetic tests can help find people who carry genes for certain hereditary diseases. For example, having a mutation in the BRCA1 gene can increase the risk of breast cancer in women by up to 72%.
   • A study by Pew Research in 2020 found that 59% of Americans feel that genetic testing could raise ethical concerns.

2. Designer Babies:

   • A study from 2018 found that 27% of parents might think about gene editing to improve traits like intelligence.
   • But, there are risks. We don’t know what the long-term effects might be, and there are big ethical questions linked to eugenics, which is about improving the human population.

3. Gene Therapy:

   • In 2021, about 30 new gene therapies were approved around the world. These therapies can offer cures for some diseases that couldn't be treated before.
   • Still, 60% of geneticists surveyed are worried about how gene editing could be misused.

In summary, while changing genes can improve healthcare, it also brings up complicated ethical questions that we need to consider carefully.
