Q. The relative five-year survival rate for ovarian cancer is 50%, (50% of patients diagnosed in a particular year will die in 5 years). In 2012, it was estimated that ovarian cancer occurred in 239,000 women and resulted in 152,000 deaths worldwide. What is the market size in 2017?
This is from a real business situation that I was trying to solve for myself. I made some assumptions and arrived at ~2.1 million patients. How would you solve the problem, and what assumptions would you make?
