Modern medicine is moving away from a one-size-fits-all approach. Today, thanks to advances in biotechnology, treatments can be tailored to an individual’s unique genetic makeup, lifestyle, and environment, a concept known as personalised medicine. Unlike traditional medicine, which relies on standard treatments, personalised medicine uses a patient’s DNA, biomarkers, and molecular information to design therapies that are more effective, safer, and targeted. This approach is revolutionising healthcare, offering new hope for patients with conditions like cancer, diabetes, and rare genetic disorders.
Personalised medicine begins with genetic testing. By analysing a patient’s genes, scientists can identify mutations or variations that influence disease risk or drug response. For instance, in cancer treatment, genetic profiling of tumours helps doctors choose the most effective drugs for that specific patient, reducing side effects. Similarly, pharmacogenomics studies how an individual’s genes affect drug metabolism, allowing doctors to prescribe precise dosages. Additionally, lifestyle and environmental factors are considered to create comprehensive treatment plans tailored to each patient.
Biotechnology plays a central role in developing personalised medicine. Techniques like gene sequencing, CRISPR gene editing, and molecular diagnostics help researchers understand disease mechanisms at a molecular level. Advanced bioinformatics tools analyse large datasets to predict treatment responses, enabling precision therapies. Biotechnology not only improves patient outcomes but also accelerates drug development, making healthcare more efficient and innovative.
“For school and college students interested in pursuing careers in personalised medicine and biotechnology, the field offers diverse opportunities. Careers include biotechnologists, genetic counsellors, molecular biologists, bioinformaticians, and clinical research scientists. Biotechnologists work on developing targeted therapies, while genetic counsellors help patients understand their genetic risks and treatment options. Bioinformaticians analyse complex genetic data, and clinical researchers design and test new drugs,” Ankit Singh, an alumnus from Apeejay Stya University, shared.
“Aspiring professionals typically study Biology, Chemistry, and Mathematics in school, followed by undergraduate and postgraduate degrees in biotechnology, genetics, or related life sciences,” he said in conclusion.
