Risk of stroke and pulmonary embolism is higher while being treated for cancer (cancer makes the blood hypercoagulable and thus significantly increases the chance of clots), and that’s what sadly took O’Hara’s life last month. Via Deadline:

The beloved star of Schitt’s Creek, SCTV and Home Alone died of a pulmonary embolism with rectal cancer as the underlying cause, according to the death certificate issued by the Los Angeles County Health Department, reported by TMZ.
