WE PUT A MAN ON THE MOON

So, we should have a cure for cancer by now. Cancer actually includes a large group of diseases. Each can be caused by many different factors. Despite advances in diagnosis and treatment, doctors still have much to learn about what triggers a cell to become cancerous and why some people with cancer do better than others.

In addition, cancer is a moving target. Cancer cells may continue to mutate and change during the course of the disease. This may lead to the cancer cells no longer responding to the chemotherapy drugs or radiation treatments that were given initially.

Finding the cure for cancer is, in fact, proving to be more complex than mastering the engineering and physics required for space flight.
