The ct scan detects a tiny spot that could be inflammation from bronchitis or cancer not clear, but the biomarker test clinches the diagnosis, revealing a genetic mutation that occurs only in patients with cancer. In 2015, today her prognosis from this cancer would be pretty grim. But in 2018 that could all change. Lily is treated with surgery to remove the tumor and the tumor dna undergoes molecular analysis.
