The 7 signs of colorectal cancer that should alert you

Symptoms of colon cancer and rectal cancer are not always easy to recognize, which misses opportunities for early diagnosis. For one thing, many people with cancer of the colon or rectum (known as colorectal cancer) experience no symptoms until the disease has reached a more advanced stage, where it is more difficult treat. This is why screening tests in apparently unaffected people is of paramount importance.

Early detection: a major asset

The decline in colorectal cancer deaths in recent decades is due in part to increased screening efforts that identify asymptomatic cancers. Screening tests can also identify abnormal growths called colorectal polyps, some of which may be precancerous. When doctors remove potentially dangerous polyps, they stop the cancer before it starts. Another complication of diagnosing colon cancer and rectal cancer is that even when symptoms are present, people with cancer and doctors can both blame other common conditions, such as hemorrhoids or irritable bowel syndrome. .

Also, many younger people think that colorectal cancer only affects older people, and so are likely to be unaware of the symptoms. However, while the vast majority of colorectal cancers are still seen in older people, rates in men and women under 50 are rising sharply.

  • A change in bowel habits such as diarrhea, constipation, or narrowing of stool (faeces) that lasts for more than a few days.
  • A feeling of need to have a bowel movement that is not relieved by defecation.
  • Rectal bleeding with bright red blood
  • Presence of blood in the stools, which can make them look dark.
  • Abdominal (belly) cramps or pain
  • Weakness and fatigue
  • Unintentional weight loss
  • Although people with colorectal cancer may not experience rectal bleeding or blood in the stool, for many these are the most identifiable signs of the disease.

    These symptoms occur when the cancer spreads through the digestive tract. This can happen very slowly, over years, so the presence of blood in the stool may not even be noticeable. Over time, this continued loss of blood can lead to a decrease in the number of red blood cells, a condition called anemia. Blood tests that diagnose anemia can be the first step in diagnosing colon or rectal cancer.

    Discuss symptoms with your doctor

    Once you describe the symptoms to your doctor, they will likely give you a physical to determine the cause. The doctor will likely ask you about your medical history and ask if any family members have colorectal cancer, especially your parents, siblings, or children. Most people who develop colorectal cancer have no family history of the disease, but 1 in 5 do.

    The main risk factors for colorectal cancer

    In rare cases, genetic mutations passed down through families, such as Lynch syndrome, can make a person extremely vulnerable to colorectal cancer. Your doctor will want to know if you have other health conditions, especially those involving the colon and rectum, that may increase the risk of colorectal cancer. These may be a history of colorectal cancer or precancerous polyps or an inflammatory bowel disease such as Crohn’s disease or ulcerative colitis. There is also an association between type 2 diabetes and colorectal cancer. Other risk factors include obesity or overweight, low level of physical activity, heavy alcohol consumption and smoking.

    What exams to get to the bottom of it?

    A physical examination and blood tests are part of the health check. Once the doctor is aware of your medical history, the next step may be a physical examination of your body which includes gentle pressure on your abdomen to detect any lumps or enlarged organs. The doctor may also examine your rectum by placing a gloved, lubricated finger inside it to check for any abnormalities. The doctor may order blood tests to look for changes indicating the presence of colorectal cancer.

    This is not only a test to see if you are anemic, but also tests that measure liver enzymes and substances called tumor markers. If you have not seen rectal bleeding or blood in the stool, the doctor may advise you to take a test to identify hidden blood. These tests, which include a stool blood test and a fecal immunochemical test, involve collecting one or more stool samples at home, packing them in a special container, and returning them to the doctor’s office or medical laboratory. .

    Your doctor may suggest a colonoscopy

    You can also leave the doctor’s office with a prescription for a diagnostic colonoscopy. During this procedure, a gastroenterologist examines the inside of the colon and rectum using a device inserted through the anus: a long, thin, flexible light tube with a tiny video camera attached to it. its end. If the examination reveals any suspicious growths, the gastroenterologist may remove tissue for biopsy to determine whether or not cancerous cells are present. The night before a colonoscopy, people having the exam should clean the colon and rectum. This procedure involves drinking a strong laxative solution. People who have a colonoscopy are usually sedated during the procedure.
