This means they can choose the best treatment for us right from the start, cutting down on guesswork, improving how well treatments work, and reducing unwanted side effects.
For example, in cancer treatment, doctors use genetic information from a patient’s tumor to select a therapy that targets the tumor’s specific genetic abnormalities. This approach can lead to more effective and less harmful treatments compared to traditional chemotherapy that affects both healthy and cancerous cells.
Technologies like CRISPR, a tool for editing genes, and next-generation sequencing, which quickly reads a person’s entire genetic code, are key players in making personalized medicine possible. They allow scientists and doctors to understand a patient’s genetic landscape and craft treatments that are just right for them. This is not only good news for patients but also speeds up the process of developing new drugs. By focusing on people with specific genetic markers, researchers can more accurately test new treatments.
Take cystic fibrosis as an example. It’s a genetic disorder that, in the past, had limited treatment options. Now, with the help of personalized medicine, treatments can target the specific mutations causing the disease in each patient, offering hope where there was little before.
