Targeted therapies are drugs designed to specifically interfere with molecular targets involved in cancer cell growth and survival. Unlike traditional chemotherapy, which affects both cancerous and healthy cells, targeted therapies aim to minimize damage to normal cells. Examples include PARP inhibitors like olaparib for patients with BRCA mutations and CDK4/6 inhibitors like palbociclib for hormone receptor-positive breast cancer. These treatments have led to improved outcomes and reduced side effects for many patients.
