Doctor explains BOWEL CANCER (Colorectal cancer) | Signs, Symptoms, Screening, Risk factors

Bowel cancer, also known as colorectal cancer, is a significant health concern that affects thousands of individuals each year. Understanding the signs, symptoms, and risk factors associated with this disease is crucial for early detection and effective treatment. In my recent video, I engaged with members of the public to gauge their awareness of bowel cancer, and the responses were enlightening. Here, I will delve deeper into the key points discussed in the video, providing you with essential information that could potentially save your life.

Understanding the Bowel

To begin, it’s important to understand the anatomy and function of the bowel. The bowel, or intestines, is divided into two main sections: the small bowel and the large bowel. The small bowel, which consists of the duodenum, jejunum, and ileum, is primarily responsible for digesting food and absorbing nutrients. In contrast, the large bowel, which includes the colon, rectum, and anus, absorbs water from leftover food and forms solid waste, commonly referred to as stool.

Recognizing Signs and Symptoms

When it comes to bowel cancer, early detection is key. The public responses highlighted several potential signs and symptoms, including:

1. Blood in Stool: One of the most recognized symptoms is the presence of blood in your stool or bleeding from the rectum. While this can be alarming, it’s important to note that not all bleeding is indicative of cancer. Conditions such as hemorrhoids or benign polyps can also cause similar symptoms. However, if you notice dark red or black blood, it’s crucial to seek medical advice promptly.
2. Abdominal Pain: Persistent abdominal pain, especially if it lasts for three weeks or more, should not be ignored. While many conditions can cause abdominal discomfort, it’s essential to consult your doctor to rule out any serious issues.
3. Changes in Bowel Habits: Changes in your bowel habits, such as diarrhea, constipation, or a feeling of incomplete evacuation, can also be symptoms of bowel cancer. If you experience a significant change in your bowel movements that lasts for an extended period, it’s advisable to seek medical attention.
4. Unexplained Weight Loss and Fatigue: Unintentional weight loss and persistent fatigue can be signs of various health issues, including bowel cancer. These symptoms may be related to anemia, which can occur when the cancer causes internal bleeding.
5. Bowel Obstruction: In some cases, a tumor may obstruct the bowel, leading to severe abdominal pain, bloating, and nausea. This is a medical emergency, and immediate attention is required.

The Importance of Screening

In the UK, bowel cancer screening is now offered to individuals aged 50 to 74 every two years. The screening involves a simple home test that checks for hidden blood in the stool, which can be an early indicator of bowel cancer. If you are over 75, you can still request screening through your GP.

Risk Factors for Bowel Cancer

Several risk factors can increase your likelihood of developing bowel cancer:

• Age: The risk increases significantly after the age of 50.
• Family History: A family history of bowel cancer can elevate your risk, particularly if a first-degree relative has been diagnosed.
• Lifestyle Factors: Diets high in red and processed meats, obesity, sedentary behavior, smoking, and excessive alcohol consumption are all associated with a higher risk of bowel cancer.
• Chronic Conditions: Conditions such as inflammatory bowel disease (IBD) can also increase your risk.

Taking Action

It’s vital to be aware of what is normal for your body. If you notice any changes in your bowel habits or experience any of the symptoms mentioned, do not hesitate to consult your healthcare provider. Early detection can significantly improve treatment outcomes and survival rates.

In conclusion, bowel cancer is a serious condition, but awareness and education can empower you to take control of your health. I encourage you to watch the video for a more in-depth discussion and to check the description for additional resources and references on bowel cancer. Remember, your health is in your hands, and being proactive can make all the difference.
