Genetic Testing: The Pros and Cons
The popularity of genetic testing is increasing in recent years. This allows people to gain a better understanding about their health, as well the possible risks. Although genetic testing may provide useful information, it’s important to be aware of the possible negatives and positives. Genetic testing can identify the potential risk factors for certain diseases. This is one of its greatest strengths. According to a study published in 2018, genetic testing “has been used to identify genetic variants associated with significantly increased risk of diseases such as breast cancer, Huntington’s disease, and cystic fibrosis.” (Gleeson, 2018). The knowledge gained can be used to help people make educated decisions regarding their health, and what steps can be taken to avoid certain diseases. Genetic testing can also help doctors make treatment decisions. According to a study published in 2020, “genetic testing has been used to identify genetic variants that can affect how individuals respond to certain medications, enabling physicians to make more informed treatment decisions.” (McGill, 2020). It can allow physicians to tailor their care plans for their patients, making sure they are providing the best possible care.
