When it comes to colorectal cancer, early detection is key to effective treatment. But how do you know you have colorectal cancer? In this post, we will explore some of the most common signs and symptoms of colorectal cancer and how to identify them.

What is colorectal cancer?

Colorectal cancer, also known as colorectal carcinoma, is a disease that develops in the cells of the colon or rectum. It is one of the most common cancers and can develop slowly over several years, often being discovered too late.

Signs and symptoms of colorectal cancer

Symptoms of colorectal cancer can vary depending on the location and stage of the cancer. Some of the most common signs are:

Changes in bowel movements

These include diarrhea, constipation, or changes in stool consistency that last longer than four weeks.

Blood in the stool or rectal bleeding

It may be visible red blood or dark, tarry stools.

Abdominal pain, cramps or bloating

Permanent or periodic pain or discomfort in the abdomen.

Weight loss for no apparent reason

Unexplained weight loss may be a sign of colorectal cancer.

Fatigue or weakness

Persistent fatigue or weakness may indicate anemia, which can occur with colorectal cancer.

Early detection of colorectal cancer

The best method for early detection of colorectal cancer is regular screening, including colonoscopies and stool tests. These can help identify polyps before they develop into cancer or detect the cancer at an early stage when it is most treatable.


Colorectal cancer is a serious disease, but early detection can significantly increase the chances of cure. If you notice one or more of the above symptoms, contact your doctor. Remember, these symptoms can also indicate other health problems, so it's important to get a professional medical diagnosis.


Identifying the signs and symptoms of colorectal cancer is critical for early diagnosis and treatment. Common signs include changes in bowel movements, blood in the stool, persistent abdominal pain, unexplained weight loss and constant fatigue. Regular screening can help detect colorectal cancer early and improve the chances of cure.
