Understanding Tumor Diagnosis: From Cytology to Tumor Markers

Understanding Tumor Diagnosis: From Cytology to Tumor Markers

Learning Objective

At the end of the lesson, you will understand the laboratory methods used to diagnose tumors, including cytology, biopsy, immunohistochemistry, and tumor markers.

What do you already know about laboratory methods for diagnosing tumors?

Introduction to Tumor Diagnosis

Tumor diagnosis involves various laboratory techniques to accurately detect and classify tumors, ensuring appropriate treatment.

Cytology

Cytology involves examining cells from tissues or fluids to detect cancerous changes. It's less invasive and provides quick results.

Biopsy

A biopsy involves removing tissue samples to examine under a microscope. It's crucial for accurate tumor diagnosis and classification.

Immunohistochemistry

Immunohistochemistry uses antibodies to detect specific antigens in tissue samples, aiding in tumor identification and classification.

Tumor Markers

Tumor markers are substances found in blood, urine, or tissues indicating cancer presence. They aid in diagnosis, monitoring, and prognosis.

Integrating Diagnostic Methods

Combining cytology, biopsy, immunohistochemistry, and tumor markers enhances diagnostic accuracy and treatment planning.

Conclusion and Discussion

Reflect on the importance of laboratory techniques in diagnosing tumors and how they guide treatment decisions.
