Why is targeted therapy often more effective than traditional chemotherapy?

• A. It affects all rapidly dividing cells
• B. It requires larger dosages of medication
• C. It focuses on specific characteristics of cancer cells
• D. It combines multiple drug types

Answer: (C)

Targeted therapy is often considered more effective than traditional chemotherapy primarily because it focuses on specific characteristics of cancer cells. This approach involves the use of drugs that specifically target molecular pathways that are uniquely altered in cancer cells. These alterations can include mutations, overexpressed proteins, or other defects that differentiate cancer cells from normal cells. By zeroing in on these specific targets, targeted therapies can induce cell death in cancer cells while minimizing damage to healthy, normal cells. In contrast, traditional chemotherapy generally acts on all rapidly dividing cells, which means it can affect both cancerous and healthy cells. This broad approach can lead to significant side effects and reduced effectiveness, as normal cells that also divide rapidly, such as those in the gastrointestinal tract and bone marrow, can be harmed. Additionally, targeted therapies do not require larger dosages of medication nor do they necessarily involve the combination of multiple drug types. Instead, their design is meant to be more precise and effective, often resulting in fewer side effects and improved patient outcomes.
