When cancer spreads from its original location, it does not happen by chance. It is a complex, systemic process. New research shows that the way our immune system fails is more complicated than just a simple lack of defense. Instead, the body's immune cells are actually remodeled to help the cancer move.
Scientists looked at how various immune cells, such as T cells and macrophages, change their behavior. These cells are part of our natural defense system, but in the case of cancer, they can be hijacked. They help create a special environment that prepares other parts of the body for the cancer to land and grow.
This process involves several types of immune cells, including neutrophils and dendritic cells. They work together to create what experts call a pre-metastatic niche. This is a space where the cancer prepares the ground before it even arrives. While this research highlights the complex ways cancer moves, it is a broad overview of these mechanisms.
