Margaret Mueller battled through 24 cycles of chemotherapy over a 3 1/2-year span, with little improvement to her condition. Growing desperate, she sought out a different oncologist to ask about other treatment options.

The new doctor, however, made a shocking revelation. Mueller didn’t have ovarian cancer, as she had been told. She had been misdiagnosed and actually had cancer of the appendix. The truly tragic news was that the cancer was too far along to be treated. She wouldn’t survive. She died last year at age 62.
