Colorectal Cancer: Symptoms
What are the symptoms of colorectal cancer?
People with colorectal cancer often do not have symptoms right away. By the time symptoms occur, the cancer may have grown or spread to other organs. This can make it harder to treat. That’s why routine colorectal cancer screening is important.
Symptoms can include:
A change in bowel habits that lasts for more than a few days, such as diarrhea, constipation, or a feeling that your bowel is not empty after a bowel movement
Bright red or very dark blood in your stool
Stools that are thinner than usual
Stools that look slimy or have mucous on them
Ongoing gas pains, bloating, fullness, or cramps
Unexplained weight loss
When to see your healthcare provider
These symptoms can also be caused by many kinds of common health conditions. A healthcare provider will need to find out if your symptoms are caused by cancer. Talk with your healthcare provider if you have any of the above symptoms.
