In the German language the word Schmuck means jewelry, adornment. The etymology of the pejorative meaning is a matter of some disagreement. The lexicographer Michael Wex, author of How to Be a Mentsh (And Not a Shmuck), writes that the Yiddish term and the German term are completely unrelated.
A fundamental philosophy of medical oncology, including combination chemotherapy, is that different drugs work through different mechanisms, and that the results of using multiple drugs will be synergistic to some extent.
Chemotherapy (also called chemo) is a type of cancer treatment that uses drugs to destroy cancer cells. Chemotherapy works by stopping or slowing the growth of cancer cells, which grow and divide quickly. But it can also harm healthy cells that also divide quickly such as those which line your mouth and intestines or allow your hair to grow.
