What is Colorectal Cancer?

Colorectal cancer is a type of cancer that starts in the colon or the rectum, parts of the large intestine in the digestive system. Being one of the most common types of cancer in the UK, it requires significant public awareness and understanding. This cancer can also be referred to as bowel cancer, colon cancer, or rectal cancer, depending on where it originates.

Causes and Risk Factors

The exact causes of colorectal cancer are not fully understood, but certain risk factors have been identified. Age is a significant factor, with the risk increasing as people age. Most cases occur in people over 50, although younger individuals can be affected. Other risk factors include having a family history of colorectal cancer, a personal history of polyps or inflammatory bowel disease, a diet high in red or processed meats, physical inactivity, obesity, smoking, and excessive alcohol consumption. Genetic factors and inherited syndromes like familial adenomatous polyposis (FAP) and Lynch syndrome also contribute to higher risk.

Symptoms

In its early stages, colorectal cancer may not present any symptoms, which is why screening is crucial. However, as the disease progresses, symptoms may include a change in bowel habits (such as diarrhoea or constipation), blood in the stool or rectal bleeding, abdominal discomfort or pain, unexplained weight loss, and fatigue. If you experience any of these symptoms, it is essential to consult with a healthcare professional for an evaluation.

Screening and Diagnosis

Screening is a vital tool in the early detection and prevention of colorectal cancer. In the UK, bowel cancer screening is offered to people aged 60-74 every two years. Testing typically involves a home testing kit that checks for hidden blood in the stool, which might indicate cancer. If abnormalities are found, further tests, such as a colonoscopy, may be recommended to confirm the presence of cancer or polyps. Early detection through screening significantly increases the chances of successful treatment.

Treatment Options

Treatment for colorectal cancer depends on the stage and location of the cancer, as well as the patient’s overall health. Options may include surgery to remove the cancer, chemotherapy, radiation therapy, targeted therapies, and immunotherapy. The treatment plan is typically decided by a multidisciplinary team of healthcare professionals. Early-stage cancers may only require surgery, while more advanced stages might need a combination of treatments.

Prevention

While not all cases of colorectal cancer can be prevented, certain lifestyle changes can reduce the risk. Eating a balanced diet rich in fruits, vegetables, and fiber, maintaining a healthy weight, engaging in regular physical activity, limiting alcohol intake, and avoiding smoking are all effective preventative measures. Regular screening and awareness of personal and family medical history are also crucial components in prevention strategies.

What is Colorectal Cancer?

Colorectal cancer is a kind of cancer that starts in the colon or rectum. These are parts of the large intestine in your tummy. It is one of the most common cancers in the UK. This cancer is also called bowel cancer, colon cancer, or rectal cancer.

Causes and Risk Factors

Doctors do not know all the reasons why people get colorectal cancer. But some things can make it more likely. Getting older is one big reason, especially for people over 50. Other reasons include having family members who had it, eating lots of red or processed meats, not being active, being overweight, smoking, and drinking a lot of alcohol. Some illnesses that you can inherit from your family can also make it more likely.

Symptoms

At first, colorectal cancer might not cause any symptoms. That is why checking for cancer is important. As time goes on, people might notice changes in their bowel movements, blood in their poo, stomach pain, losing weight unexpectedly, or feeling very tired. If you have these signs, see a doctor.

Screening and Diagnosis

Checking for colorectal cancer early can help stop it from growing. In the UK, people aged 60-74 get a chance to do a screening test every two years. This test looks for hidden blood in the poo. If the test finds something unusual, more tests might be needed. Finding cancer early makes it easier to treat.

Treatment Options

Treatment for colorectal cancer depends on how much it has spread and where it is. It might include surgery, medicines like chemotherapy, radiation, or special medicine that targets the cancer. A team of doctors will help decide the best plan. If the cancer is caught early, sometimes surgery is enough.

Prevention

You cannot completely stop colorectal cancer, but you can do things to lower the risk. Eating healthy foods like fruits, vegetables, and whole grains, staying at a healthy weight, exercising, drinking less alcohol, and not smoking can all help. Getting regular check-ups and knowing your family’s health history are also important.
