They have found a new technique for fighting cancer cells: By shrinking physicians, they are able to put them into the patients' bodies and have them go to where the cancer cells are to treat them more efficiently. Once the physicians are inside the body, they only have seven minutes to fight cancer! After 7 minutes, they will turn back into their normal size again. And now YOU are on this mission to go inside the body. Fighting cancer. With the help of an audio transmitter, you are connected to the outside world where doctors will consult you on what to do, how to get to the cells, how to detect cancer cells and how to fight them.
