I'm having trouble deciphering a cause of death. So far here's what I think:
line (a) cause: ? , onset: 1 week
line (b) perforated Ca -- sigmoid, onset: 7 mos. (months)
I'm guessing line (b) indicates a perforated colon related to sigmoid colon cancer, and that cancer was diagnosed 7 months ago? What then, is the immediate cause of death?
