Doctors find fly in 63-year-old man's intestine

A man visiting the hospital for a colon cancer screening was shocked to discover a fly inside him during the procedure. Doctors found the insect on the wall of his intestines when they inserted a camera. The patient did not feel the fly inside him, and it was only noticed after the doctors took a picture. The circumstances surrounding this rare occurrence are mysterious, leading to speculation about the man's diet. The man had eaten pizza and lettuce prior to his appointment. Doctors proposed that the fly could have entered through his mouth or rectum, although this seems unlikely.
