Jeremy Clarkson , 56, opened up about a frightening moment where he “figured” he had bowel cancer. The Grand Tour host revealed he “nearly had a heart attack” when he spotted a red stain around the toilet bowl after going to the bathroom. Recalling the shocking moment in his column for The Sun, Jeremy explained: "I looked back to see what I'd produced and damn near had a heart attack." Describing the scene, he said the "whole bowl was stained blood red”.

Jeremy Clarkson speaks out after fan claims he's not been on TV

Well that's it, I've got bottom cancer.

The former Top Gear star then admitted he jumped to the conclusion that he had bowel cancer.

Jeremy recalled his thought process at the time, adding: "Well that's it, I've got bottom cancer."

Much to the presenter’s relief, he suddenly remembered he tucked into some beetroot the night before.

Joking about his realisation, Jeremy continued in reference to the vegetable: “I swear to God that stuff should come with a health warning, advising people that it will make your number twos the colour of Marilyn Monroe’s lips.”

The outspoken TV personality went on to explain how the cancer scare made him worry about leaving his three children, Emily, 25, Finlo, 21, and 23-year-old Katya.

Jeremy’s health admission comes after he complained about doctors’ claims regarding hay fever.
