Targeted Cancer Therapy Basics
Introduction
Targeted Cancer Therapy Basics refers to a type of treatment designed to specifically attack cancer cells while minimising damage to normal cells. Unlike traditional chemotherapy, which affects all rapidly dividing cells, targeted therapies focus on particular molecules or pathways involved in cancer growth and progression.
This approach uses drugs or other substances to interfere with specific targets that are involved in the development and spread of cancer. These targets may include proteins, genes, or the tumour environment that supports cancer cells.
