With AI-driven tools, doctors can analyze a patient’s genetic makeup, medical history, and lifestyle factors to create a treatment plan that is unique to them.
Liquid Biopsy: A Non-Invasive Diagnostic Tool
Liquid biopsy is one of the most exciting advances in personalized medicine. This non-invasive diagnostic tool detects cancer markers in a patient’s blood, providing an early warning system for cancer and other diseases. Liquid biopsies are now being used to monitor treatment responses, detect minimal residual disease, and even predict the risk of relapse in cancer patients.
Case Study: Targeted Cancer Therapies
A major development in cancer care is the use of targeted therapies based on genetic profiling. For instance, patients with non-small cell lung cancer (NSCLC) can now receive treatments specifically designed to target mutations in the EGFR gene. This approach has led to better outcomes and fewer side effects compared to traditional chemotherapy. As the use of AI and genetic sequencing continues to expand, personalized cancer treatments will become more precise, leading to better survival rates and a reduction in treatment costs.
