Catherine O’Hara, acclaimed actress known for 'Schitt's Creek,' 'Home Alone,' and 'Beetlejuice,' died on January 30 at age 71 at Saint John’s Health Center in Santa Monica, California. Her death was caused by a pulmonary embolism, with rectal cancer listed as the underlying condition according to her death certificate, which was released recently. The actress had been briefly ill before her passing. O’Hara's career spanned over five decades, earning her numerous awards including an Emmy, a Golden Globe, and SAG Awards, notably for her role as Moira Rose in 'Schitt’s Creek.' Her death prompted widespread tributes from Hollywood, including heartfelt messages from Macaulay Culkin and Martin Short. The death certificate also revealed she was diagnosed with rectal cancer, a disease that often remains symptomless until advanced stages, with symptoms like rectal bleeding and associated risk factors such as diet, obesity, smoking, and alcohol use. Rectal cancer is treatable, especially when detected early, through surgery, chemotherapy, radiation, or targeted therapies. The diagnosis highlights the importance of early detection and awareness of colorectal cancers, which are increasingly leading causes of cancer-related deaths among younger populations.
