Molecular diagnostics involve analyzing genes, proteins, and other molecules to obtain information about a cancer. Techniques such as next-generation sequencing (NGS), polymerase chain reaction (PCR), and liquid biopsy are revolutionizing cancer monitoring. They enable the detection of genetic mutations, expression levels of specific biomarkers, and even the presence of circulating tumor DNA (ctDNA) in the bloodstream. These insights can guide personalized treatment plans and monitor the effectiveness of therapies in real time.
