Targeted therapy is a type of cancer treatment that focuses on targeting specific genes, proteins, or pathways that contribute to the growth and survival of cancer cells. It aims to selectively kill cancer cells while minimizing damage to healthy cells. This approach to treatment usually involves the use of drugs that target specific molecules or pathways involved in cancer development and progression. Targeted therapy is often used in combination with other cancer treatments, such as chemotherapy or radiation therapy, to improve outcomes for patients with certain types of cancer.
