What Is Chemotherapy?

Chemotherapy involves the use of drugs to kill or slow the growth of cancer cells. These drugs circulate through the bloodstream, making them effective for cancers that have spread to other parts of the body.

How Chemotherapy Works

1. Targeting Rapidly Dividing Cells
   Cancer cells grow and divide faster than most normal cells. Chemotherapy targets these rapidly dividing cells to stop their growth.

2. Different Mechanisms

• Cell Cycle-Specific Drugs: Attack cancer cells during specific phases of their growth.
• Non-Specific Drugs: Kill cells at any stage of their life cycle.

3. Combination Therapy
   Chemotherapy is often combined with other treatments like radiation or surgery for maximum effectiveness.
