Is it cost-effective to switch fromdoing a mastectomy to a lumpectomy?Explain/show work.

b.Supposeinsteadthe insurance company would like to know whether to switch, using a quality-adjusted life year(QALY)approach. The following information is given you to incorporate into your CEA analysis:

You are expected to live another 40 years.

The mastectomy will cure you, but at the cost of 10 less years of life.The lumpectomy will cure you, but at the cost of18lessyears of life.

Given the threshold value of $2,000/QALY, is it cost effective to switch?

c. Did you come to the same conclusion in part b. as you did in part a. with respect to the cost-effectiveness of switching to lumpectomy? Explainconceptually (intuitively)why or why not. Do not just explain the math in words.
