Linzi Page believes that his colon cancer has not been diagnosed early because doctors do not expect people under 50 to have this disease.
This 36-year-old Scottish woman went to the family doctor in January of last year, after weeks of "Foreign" bowel movements and rectal bleeding.
He explained to the BBC Scotland, his doctor did not take it seriously and said it was probably irritable bowel syndrome.
The doctor performed a routine blood test and a stool sample, but nothing irregular appeared.
Almost three months later, Linzi went to see another doctor and had him perform an "urgent colonoscopy."

In late April, he was diagnosed with stage IV colon cancer and since then, They gave him two years of life.
Linzi, who has two young children, believes his prognosis would have been better had they detected cancer earlier.
"I think doctors should be more aware that people under 50 They also have bowel cancer, "he says.
"I talked to my doctors and I was very honest, I told them that if I had gone with the same symptoms at age 60, they would have sent me a colonoscopy right away."
"But because I'm 35 years old they did not take it seriously and did not solve it fast enough"
Difficult for doctors
Colon cancer is the second most deadly cancer in Scotland.
About 3,700 people are diagnosed with this condition each year, but only about 200 are under 50.
According to Claire Donaghy of Bowel Cancer UK, it is difficult for doctors to recognize bowel cancer in younger people, especially due to the prevalence of irritable bowel syndrome and other conditions.
"Throughout your life, a doctor usually sees just one person under the age of 50 who has colon cancer, "he says.
Donaghy says younger patients generally do not need to worry, but should note their symptoms and return to their doctor if they do not improve.

Linzi says her diagnosis left her "destroyed".
Since then, he has discovered that he has tumors in the liver and that The cancer spread to the lungs.
"In December they told me it was incurable and gave me one or two years of life," he says.
He is currently trying to raise funds for a drug called Avastin, which is not available in the Scottish health care system but which he hopes will extend his life.
Linzi would like doctors had more in mind the risk of bowel cancer in young people.
The health system in Scotland currently has a screening program for people over 50 years of age.
Linzi asked for the assessment to be extended to people under 50, but the Scottish government said that there was not enough evidence that this was necessary.
Liz says she does not want to waste time complaining about doctors, but wants to make young people aware of the condition.
"What's really precious to me is spending time with my kids," he says.
"To think that maybe I'm not in my children's lives makes me want to cry. I can not think of that. I try to live every day."
