Although the trolley problem has numerous variations, its basic form presents you with an agonizing ethical choice. A runaway train is speeding down a track. If you pull a switch to redirect the train to another track, you will save five people. But if you do pull the switch, the train will kill one person on the other track. Should you pull the switch and sacrifice one life to save five lives? Dr. Marya Zilberberg, an epidemiologist, applies the trolley problem to a discussion of medical ethics involving the use of mammography: Suppose you are a policy maker, and you recommend that every woman at age 40 start to receive an annual screening mammogram to reduce deaths from breast cancer. At the population level, if we screen 1,000 women for about 30 years, we will save approximately 8 of them from a breast cancer death.
