Module 2: Understanding Cancer Metastasis

A deep dive into the complex process of cancer metastasis, from molecular mechanisms to clinical applications and therapeutic strategies.

Therapeutic Strategies: Fighting Metastasis

Current approaches and future directions for preventing and treating metastatic disease

From Understanding to Action

Our understanding of metastatic biology has led to the development of multiple therapeutic strategies, each targeting different aspects of the metastatic cascade. The key is to match the right strategy to the right patient at the right time.

The most effective approach often involves combining multiple strategies to target different steps in the metastatic process simultaneously.
