Cancer Stages video ch. 23

What are the three primary variables used in the cancer staging system discussed?

• Tumor size, Nodule count, Metastasis

• Tumor size, Lymph node involvement, Metastasis

• Tissue type, Nodule size, Molecular markers

• Treatment response, Nodal spread, Metabolic activity

In the TNM staging system, what does the letter 'T' primarily indicate?

• The type of treatment required

• The size of the primary tumor

• The number of affected tissues

• The patient's overall health

How do cancer cells typically travel from the initial tumor to other parts of the body to form new tumors?

• Through the circulatory system

• Through the lymphatic system

• Through direct contact with other organs

• Through nerve pathways

Why has the medical community recently rethought the 'M' stage (metastasis) from a simple "yes or no" to a "continuum"?

• New surgical techniques have made metastasis easier to remove.

• Advances in imaging technology allow for more precise measurement of metastatic tumors.

• A subset of advanced cancers has shown better response to existing treatments than previously thought.

• Patients with metastatic cancer are now living longer, requiring a more nuanced classification.
