Precision oncology tailors treatment to your tumor's genetic blueprint, using NGS to spot mutations like BRCA in breast or KRAS in colon. From 2010s boom, 2025 sees 60% advanced patients benefit, with matched therapies doubling responses. Process: Biopsy → sequencing (₹20,000-50,000) → match drugs (e.g., PARP inhibitors for BRCA). Benefits: Avoids ineffective chemo, reduces toxicity. Challenges: Cost and access. Myths: "Only rich" can afford—generics help. It's future: From off-label to trials. Empower yourself: Ask for profiling from your oncologist. Precision turns one-size-fits-all to you-fit-best.
