Biotechnology in Personalized Medicine

Personalized medicine, also known as precision medicine, is an emerging approach to healthcare that tailors medical treatment to individual patients based on their unique genetic profiles, lifestyle factors, and environmental influences. Biotechnology plays a crucial role in enabling this personalized approach by providing tools and techniques for analyzing genetic information and developing targeted therapies.

Introduction to Personalized Medicine​

Personalized medicine aims to move away from the traditional "one-size-fits-all" approach to healthcare. Instead, it focuses on:

  • Identifying genetic variations that contribute to disease susceptibility
  • Developing treatments tailored to an individual's specific genetic profile
  • Monitoring patient responses to treatments in real-time

This approach has the potential to significantly improve treatment outcomes and reduce side effects compared to conventional methods.
