This Morning 's Dr Zoe Williams explained the signs and causes of colon cancer on the ITV show today.
The 40-year-old medical expert spoke to hosts Holly Willoughby and Phillip Schofield about the cancer after it was revealed at the weekend Black Panther star Chadwick Boseman died from it aged 43.
Colon cancer is a type of cancer that begins in the large intestine. The colon is the final part of the digestive tract.
Dr Zoe explained that if the cancer is caught early it is "almost always curable".
She said that people need to keep a check on their poo to look for any differences.
Dr Zoe said: "Is it hard, soft or is there blood?"
The medical expert also said there is two different types of genetic conditions so if family members had suffered from the cancer or died from it she recommended telling a GP.
Zoe also said that 9/10 cases of colon cancer arise in people over 50.
However, she said it does affect younger people too - tragically with Chadwick included in that.
The expert said fibre helps protect against the cancer as the condition is causes by the stool.
Whereas she said red meat, alcohol and smoking can all increase the risk.
It was revealed on Saturday August 29 that Marvel star Chadwick had died.
A heartbreaking post was shared onto the star's Instagram account announcing the actor's death after being diagnosed with stage four colon cancer.
