It is one of the deadliest types of cancer, killing almost 80,000 people in the UK and US each year.
But like most tumors, not everyone knows the characteristic symptoms.
Experts say the lack of awareness can affect survival, with early diagnosis key to fighting the disease.
Here, MailOnline highlights the warning signs of colon cancer so you know when to speak to a professional.
Colon cancer can cause blood in the stool, a change in bowel habits or a lump in the bowel that can cause constipation. Some people also experience weight loss as a result of these symptoms
Blossoms
Finding blood in your stool can be alarming.
Bright red blood – indicating that it is fresh – can be caused by hemorrhoids.
But drops of blood in your stool can also be caused by benign growths called polyps, according to Bowel Cancer UK.
However, dark or black blood can be a sign of cancer, That’s what cancer research says.
Because intestinal tumors, which are usually located higher up in the digestive tract, can cause internal bleeding.
Anyone who has blood in their buttocks should see their doctor to find out what is causing it.
Screening programs also look for occult blood in the stool and also for polyps, as these can develop into cancer.

Change in bowel habits
Changes in your usual bowel habits can also be a possible warning sign of colon cancer.
It could be as simple as going to the bathroom more often or feeling like you’re not emptying your bowels completely.
“One possible indicator of colon cancer is any significant change in your bowel habits – which can vary from person to person,” says colon surgeon James Kinross of the King Edward VII Hospital in London.
He added: “For example, having a bowel movement more often than usual or having looser, thinner stools.
“It’s probably related to an external factor such as stress, more fiber or a change in diet, but it’s worth getting checked out if the problem persists.”
This change in habit can be caused by the presence of a tumor that causes partial bowel obstruction and constipation.
It can also cause diarrhea if the washed fluid leaks into your intestines.
The change may be happening for no apparent reason, and if it lasts longer than three weeks, you should get it checked out by your doctor, says Macmillan.
weight loss
Although this is an uncommon sign of colon cancer, unexplained weight loss is still something to watch out for and report to your doctor.
This symptom could be due to a tumor making you sick or bloated, says Bowel Cancer UK.
A tumor can also block the bowel, which can cause stomach pains that prevent you from eating, the charity explains.
Dr. Kinross said: “Butt pain can have a variety of causes, from muscle fatigue to menstrual cramps.
But it can also be a sign of colon cancer.
“Discomfort or bloating, which is always caused by eating – which can cause you to eat less and thus lose weight – should be checked by a doctor.”
fatigue
Colon cancer can make you tired.
This may be because the tumor bleeds internally, which can develop into anemia – when there is a shortage of red blood cells in the body.
As a result of a domino effect, you may feel very tired and have pale skin.
Anemia can also cause dizziness and shortness of breath, according to Macmillan.
Tumors often develop into palpable masses. Your doctor may be able to feel the lump, which is more common on your right side, says Cancer Research UK
pain or lump
A lump or pain in the abdomen or anus is a warning sign of a tumor in the intestines.
Your doctor may be able to feel the lump, which is more common on your right side, says Cancer Research UK.
It can make you feel like you have to strain even after you’ve opened your bowels.
Dr. Kinross said, “While this is probably benign, it may indicate a malignant tumor.”
You should see your GP if these symptoms don’t go away, especially if they interfere with your diet and sleep, says Bowel Cancer UK.
intestinal obstruction
Pain, bloating and nausea can sometimes be caused by an intestinal blockage, such as a tumor.
Cancer Research UK has warned that people experiencing this symptom should see their GP or go to the emergency department immediately.
This is usually a sign that the cancer has progressed.
This can happen when a tumor puts pressure on the intestine or grows in and damages the nerve supply.
“Early detection is one of the best ways to increase your chances of surviving colon cancer,” says Dr. Kinross.
He added: “And while it may seem awkward to talk about your poo – or your bowel movement – the doctors are there to listen with confidence and without judgement.
“By talking to them, they can carry out the necessary tests and treat you as quickly and efficiently as possible.”
