Cancer stem cell theory supported by study

The video discusses how chemotherapy targets rapidly dividing cancer cells, reducing tumor size. However, some cancer stem cells survive, potentially causing tumor regrowth. Researcher Louis Perrotta suggests that targeting these stem cells could improve outcomes. Studies in Nature and Science support the presence of stem cell-like properties in cancer cells, though skeptics note these findings are based on mice and may not apply to humans. Preliminary studies suggest potential applicability to humans.
