Since the 1990s, doctors have observed a worrisome trend — the number of people under 55 with colon cancer has increased dramatically. A recent American Cancer Society report finds that colon cancer in young people has doubled, increasing from 11% in 1995 to 20% in 2019. Regular screenings through colonoscopies don't begin until the age of 45, leaving many younger people wondering what signs might indicate colon cancer and warrant a visit to a doctor.
To help understand what symptoms look like for early onset colon cancer, researchers recently examined the symptoms of 5,075 people diagnosed with colon cancer under age 50, according to NBC News. The study, published in the Journal of the National Cancer Institute indicates that there are four telltale signs that can occur up to two years before a colon cancer diagnosis in young people. They include:
- Stomach pain
- Rectal bleeding
- Persistent diarrhea
- Anemia
Patients shared with TODAY.com their experience with the symptoms and what prompted them to visit a doctor.

Stomach pain
When Ashley Mellen experienced stomach pain that radiated up toward her ribs, she thought she had digestion troubles. As the pain intensified, Mellen visited the emergency room where she received a CT scan and an answer for why she felt such discomfort.
“They pulled me into a little room and they said, ‘You have tumors in several places in your abdomen. You have cancer. We’re going to be admitting you to the hospital,’” Mellen told TODAY.com.

By this time, it was stage 4. While she underwent treatment, she passed away in early April, about a year after her diagnosis.
Melissa Ursini’s abdominal pain struck her in waves radiating across her lower belly for an hour at a time. The pain eventually became constant and felt like period cramps. At first, she thought it might be gynecological and scheduled a visit with her OB-GYN. She soon learned she had stage 2 colon cancer.
“The thought of colon cancer never hit my mind,” the 39-year-old from Santa Clarita, California told TODAY.com. “I actually thought if it was any cancer, it would have been ovarian cancer … or breast cancer”
After surgery and chemotherapy, Ursini is cancer free.
“I’m hoping that people realize (colon cancer is) not an old person’s disease,” she said.
Rectal bleeding
When Joshua Sanchez noticed blood after using the bathroom, he didn’t worry at first.
“I thought I had a hemorrhoid,” the 38-year-old from New York City told TODAY.com. “I felt like something still wasn’t great because I had noticed some blood.”
Follow up tests confirmed that he had blood in his stool, and he was eventually diagnosed with stage 4 colon cancer and underwent treatment for it.
When Carly Barrett noticed blood in her stool, she looked up her symptoms online and thought that a variety of conditions could be the cause, including hemorrhoids, ulcerative colitis, irritable bowel syndrome or Crohn’s disease.
“I was like, I’m 24. I’m too young. Cancer doesn’t happen to people at this age. Cancer doesn’t happen to people who don’t have it in their family,” Barrett, now 28, from Louisville, Kentucky, told TODAY.com. “But it does.”
She was diagnosed with stage 3 colon cancer, which was changed to stage 4 after her first chemotherapy treatment failed and the cancer spread to her liver. She joined a clinical trial and no longer has evidence of disease.
Persistent diarrhea
While Natalie Phelps, then 38, felt pain in her lower back, pelvis and around her rectum while pregnant, her doctor suspected it would wane after she gave birth. Six weeks after giving birth, she went from being constipated to having loose stool. She visited numerous doctors and her primary care physician even thought therapy could help her symptoms. Finally, she underwent a colonoscopy and learned why her bowel habits had changed so much.
“I went into the colonoscopy thinking I was going to wake up with colitis or Crohn’s — something not fun, but not cancer,” Phelps from Bainbridge Island, Washington, told TODAY. "I woke up from the colonoscopy and they said, ‘We found a very large tumor and it is almost 100% cancer.”
It was stage 4 colon cancer and Phelps is still undergoing treatment for it.
Anemia
More than 20 years ago, few people were thinking about colon cancer in young people. When Candace Henley fainted and visited the hospital to see what was wrong, doctors noticed she had a low blood count. They ran several tests on the then 35-year-old and she was diagnosed with stage 2 colon cancer.
“It just didn’t make sense to me … that I had cancer,” the now 55-year-old Chicago resident and founder and CEO of the colorectal cancer nonprofit The Blue Hat Foundation told TODAY. “(The doctors) were shocked as well because here I am this 35-year-old, and I’m presenting with colon cancer.”
When blood tests showed that Al Thomas was anemic, he felt worried. His cousin had been diagnosed with colon cancer and Thomas wondered about his risk. At first, doctors assured him he would be safe because he was only 38 and his cousin wasn’t a first degree relative. Still, Thomas wanted to be sure and took an at-home colon cancer test.
“That came back showing microscopic traces of blood in my stool,” Thomas, of Lexington, South Carolina, told TODAY.com. “When you hear colon cancer again it kind of sends you in a tailspin.”
Thomas underwent treatment and is now cancer free. He hopes that others learn from his experience and speak up when something seems wrong.
“You have to advocate for yourself,” he said. “You have to be diligent and follow up.”
