Cancer remains one of the most prevalent and deadly diseases affecting humanity. According to the Centers For Disease Control, cancer was the second leading cause of death in 2020 for Americans behind heart disease. The American Cancer Society projects at least 600,000 deaths due to cancer each year, despite the fact that mortality continues to decrease each year. The majority of these deaths are from advanced cancer, which are cancers that do not respond well to treatment and therefore cannot be cured. It is when the advanced cancer progresses to a point where it can escape the primary tumor site, a process known as metastasis, that the prognosis becomes grim.
