Diagnosed With Stage 4 Colon Cancer, She Reveals 5 Symptoms She Wishes She Had Never Ignored

“I thought they were just normal problems. I never imagined they could be connected to something so serious.”

That is the message many people can relate to when it comes to colorectal cancer.

A woman diagnosed with stage 4 colon cancer has shared a warning that deserves attention: some changes in her body had seemed easy to dismiss at first. Like many people, she may have attributed them to everyday digestive problems, stress, diet, or simply getting older.

But persistent changes should not always be brushed aside.

Colorectal cancer does not always cause symptoms in its early stages, which is one reason screening is so important. When symptoms do occur, they can resemble common conditions, making them easy to overlook.

Here are 5 warning signs worth knowing:

1. A change in bowel habits

One of the most important things to watch for is a new or persistent change in your normal bowel routine.

This may include constipation, diarrhea, changes in stool appearance, or a feeling that you still need to have a bowel movement even after going.

Occasional digestive changes are common. But when a change is unusual for you and continues, it deserves attention.

2. Blood in or on the stool

Seeing blood when you use the bathroom can be frightening—but it is also something people sometimes explain away as hemorrhoids or another minor problem.

Blood in the stool can have many causes, and it does not automatically mean cancer. However, colorectal cancer is one possible cause, so unexplained or persistent bleeding should be discussed with a healthcare professional.

3. Persistent abdominal pain or cramping

Everyone experiences stomach discomfort from time to time.

But ongoing abdominal pain, aches, or cramps that don't go away are among the symptoms doctors say should not simply be ignored.

The cause could be something much less serious than cancer—but the only way to know is to have persistent symptoms evaluated.

4. Unexplained weight loss

Losing weight without intentionally changing your diet or exercise routine can have many possible explanations.

However, unintentional weight loss is a recognized warning sign that should be discussed with a healthcare professional, particularly when it occurs alongside digestive changes, abdominal discomfort, bleeding, or unusual fatigue.

5. Unusual tiredness or weakness

Constant fatigue can be easy to blame on a busy schedule, poor sleep, stress, or aging.

But colorectal cancer can sometimes be associated with anemia, which may contribute to weakness and fatigue. CDC lists low iron levels in the blood as another possible sign associated with colorectal cancer.

The most important lesson: Don't wait for symptoms

Perhaps the biggest takeaway isn't simply learning five warning signs.

It's understanding that colorectal cancer can sometimes develop without obvious symptoms.

Screening can detect colorectal cancer earlier—and some screening tests can even find precancerous polyps so they can be removed before they become cancer. Current CDC and American Cancer Society guidance recommends that adults at average risk begin colorectal cancer screening at age 45; people with certain risk factors may need to start earlier or be screened more frequently.

Risk can be higher for people with a personal or family history of colorectal cancer or polyps, certain inherited genetic conditions, or inflammatory bowel disease.

Don't panic—but don't dismiss persistent changes.

Having one of these symptoms does not mean you have colon cancer. Hemorrhoids, infections, irritable bowel syndrome, inflammatory bowel disease, and many other conditions can cause similar symptoms.

But if something about your digestion or overall health has changed and doesn't go away, it's worth finding out why.

Sometimes, listening to your body means simply making an appointment.

And when it comes to colorectal cancer, early detection can make a meaningful difference in treatment options and outcomes.

If you are 45 or older, talk with your healthcare provider about which colorectal cancer screening option is appropriate for you. And if you're younger but have symptoms or increased risk, don't assume you're “too young” to seek medical advice.
