Also Known As: Vesanoid, Retin-A
Tretinoin works somewhat differently than other drugs for cancer chemotherapy. Whereas most drugs work by directly killing cancer cells, tretinoin causes the very immature cancer cells to mature (a process known as differentiation). The mature cells then undergo a natural death.
