What is Personalised Medicine? How it Works and Why it Matters

Martin Sandhu

February 2024

Personalised medicine is transforming healthcare by tailoring treatment to individual patients rather than relying on a one-size-fits-all approach. This revolutionary concept uses a combination of genetic information, lifestyle factors, and advanced technology to provide precise and effective care.

What is Personalised Medicine?

At its core, personalised medicine focuses on delivering the right treatment to the right person at the right time. It uses tools such as:

  • Genomic Sequencing: Analysing a person’s DNA to identify genetic variations that influence health.
  • Biomarker Testing: Identifying biological indicators that guide treatment decisions.
  • Data Analytics: Leveraging AI and big data to predict disease risks and treatment outcomes.

By understanding the unique characteristics of each patient, healthcare providers can offer treatments that are more effective and minimise potential side effects.

How Does Personalised Medicine Work?

Personalised medicine follows a patient-centric process:

Data Collection
Medical professionals gather genetic, environmental, and lifestyle data through tests and patient history.

Analysis
Advanced algorithms and AI identify patterns, risks, and potential interventions based on the collected data.

Tailored Interventions
Treatments, whether preventive or therapeutic, are customised to align with the patient’s specific needs.

Why Does Personalised Medicine Matter?

Personalised medicine is not just a technological advancement; it’s a paradigm shift in healthcare. Key benefits include:

  • Improved Outcomes: Targeted treatments result in faster recovery and fewer complications.
  • Proactive Care: Identifying risks early allows for preventive interventions.
  • Empowered Patients: Individuals gain a better understanding of their health and options.

Applications of Personalised Medicine

Oncology: Personalised medicine has made significant strides in cancer care by targeting specific genetic mutations in tumours.

Cardiology: Genetic testing helps predict risks for conditions like heart disease, enabling tailored preventive measures.

Mental Health: Personalised approaches guide the selection of medications and therapies, reducing trial-and-error treatments.

Challenges in Adoption

Despite its potential, personalised medicine faces hurdles such as high costs, data privacy concerns, and the need for more education among healthcare providers.
