Monoclonal Antibodies in Cancer: How They Work

Introduction

Cancer is a complex disease, but science has given us tools to combat it with precision. Monoclonal antibodies (mAbs) are proteins created in a laboratory that target specific molecules on cancer cells. Unlike chemotherapy, which affects both healthy and cancerous cells, monoclonal antibodies are like guided missiles that only attack the intended target.

How Monoclonal Antibodies Work

Monoclonal antibodies can fight cancer in different ways:

Mechanism	How It Works	Example
Block Growth Signals	Stops cancer cells from receiving signals that help them grow.	Trastuzumab (Herceptin) for HER2-positive breast cancer
Flag Cancer Cells	Tags cancer cells so the immune system can detect and destroy them.	Rituximab for lymphoma
Deliver Toxic Payloads	Carry chemotherapy or radiation directly to cancer cells.	Brentuximab vedotin (ADC)
Boost Immune Response	Stimulate the immune system to fight more effectively.	Ipilimumab (checkpoint antibody)

Which Cancers Benefit?

Monoclonal antibodies are used in the treatment of:

Breast cancer
Colorectal cancer
Lung cancer
Lymphoma and Leukemia
Prostate cancer

Their effectiveness depends on the genetic and protein profile of the tumor, making them a form of personalized medicine.

Advantages Over Traditional Therapy

Targeted action results in fewer side effects than chemotherapy.
Includes combinations include immunotherapy, chemotherapy, and radiation.
Many cancers are now seen with better survival rates.

Limitations

Some regions have high costs and limited access.
Not suitable for all patients (depending on cancer biomarkers).
May result in infusion reactions or immune-related side effects.

Conclusion

Monoclonal antibodies offer a precise approach to cancer treatment. They have improved patient outcomes all over the world by specifically targeting cancer cells.
