All About Colon Cancer: Causes, Symptoms, Preventions
What Is Colon Cancer?
All About Colon Cancer Colon cancer starts in the large intestine, which is the last part of our digestive system. It’s like the body’s food processing system. This type of cancer mostly affects older adults but can happen at any age. It usually begins as tiny, non-cancerous growths called polyps inside the colon. These polyps often don’t cause any problems, but over time, some can turn into colon cancer.
The tricky part is that polyps don’t show any signs, so doctors suggest regular check-ups to find and remove them before they can become cancer. If colon cancer does develop, there are various treatments available, like surgery, radiation therapy, and medications, such as chemotherapy, targeted therapy, and immunotherapy.
Sometimes, people call it colorectal cancer, which includes both colon and rectal cancer. It’s important to know that with early detection and the right treatment, colon cancer can be managed effectively, and many people recover well. So, don’t worry, stay informed, and take care of your health.
What are the symptoms of colon cancers?
Change in Bowel Habits: Persistent diarrhea, constipation, or changes in stool consistency.
Blood in the Stool: Visible blood in your stool, which may be bright red or dark in color.
Abdominal Discomfort:Cramps, pain, or discomfort in the abdominal area, often lasting for an extended period.
Unexplained Weight Loss: Significant and unintentional weight loss without a change in diet or exercise.
Fatigue: Unexplained and persistent tiredness, often due to anemia caused by chronic bleeding.
Incomplete Evacuation:The feeling that you cannot fully empty your bowels after a bowel movement.
Nausea or Vomiting:Occasional nausea and vomiting, especially when a blockage is present.
Iron Deficiency Anemia: Low red blood cell count caused by chronic bleeding, resulting in weakness, paleness, and fatigue.
Abdominal Cramps:Recurring or persistent cramping in the abdominal area.
Bowel Obstruction: Severe constipation or blockage in the colon, which may lead to intense abdominal pain and vomiting.
What are the Causes of colon cancers ?
Colon cancer, also known as colorectal cancer, is a type of cancer that starts in the colon or rectum. It often begins as small growths called polyps on the lining of the colon or rectum. Over time, some of these polyps can turn into cancer.
Age: One of the main risk factors for colon cancer is getting older. It’s more common in people over the age of 50. Regular screenings, like colonoscopies, are recommended as you get older to catch any potential issues early.
Family History / Genetics: If close family members, such as parents, siblings, or children, have had colon cancer, your risk is higher. Genetic factors can play a role, so it’s important to inform your doctor if you have a family history of the disease.
Polyps: Most colon cancers start as small growths called polyps in the colon or rectum. While not all polyps become cancerous, some types are more likely to transform into cancer over time. Regular screenings can detect and remove these polyps, preventing cancer.
Diet and Lifestyle: Eating a diet high in red or processed meats and low in fruits, vegetables, and fiber may increase your risk. A sedentary lifestyle, obesity, and heavy alcohol consumption can also be contributing factors.
Smoking: Smoking tobacco is linked to an increased risk of colon cancer. If you smoke, quitting can lower your risk and improve your overall health.
Inflammatory Bowel Disease (IBD): Conditions like Crohn’s disease or ulcerative colitis that cause chronic inflammation in the colon can increase the risk of colon cancer. Regular monitoring is crucial if you have these conditions.
Diabetes: People with type 2 diabetes may have a slightly higher risk of colon cancer. Managing diabetes through a healthy lifestyle and medical care can help reduce this risk.
Race and Ethnicity: Colon cancer rates vary among different racial and ethnic groups. African Americans are at a higher risk, so they may need to start screening earlier.
Radiation Therapy: In some cases, radiation therapy used to treat other cancers can increase the risk of colon cancer. Your healthcare team will carefully consider the potential risks and benefits of any treatment.
Environmental Factors: Exposure to certain environmental factors, such as pollution or specific chemicals, can contribute to the development of colon cancer. However, these factors are not as well-documented as some of the other risk factors.
Microbiome: Emerging research suggests that the makeup of the gut microbiome, the collection of microorganisms in the digestive tract, may play a role in colon cancer. An imbalance in the microbiome might contribute to cancer development.
Hormones: There is some evidence to suggest that hormonal factors may influence colon cancer risk. This can include factors such as hormone replacement therapy and certain reproductive factors.
Infections: Infections with certain pathogens, such as some strains of the human papillomavirus (HPV), may contribute to an increased risk of colon cancer. This relationship is an area of ongoing research.
Immune System: A strong immune system is crucial for identifying and eliminating cancer cells. Conditions that weaken the immune system can potentially increase the risk of colon cancer.
What are the Preventions of colon cancer ?
Preventing colon cancer involves making healthy lifestyle choices and getting regular check-ups.
“Early detection is the key to successful treatment of colon cancer. Regular screenings can save lives.”
Dr. Lisa C. Richardson Director of the Division of Cancer Prevention and Control at the Centers for Disease Control and Prevention (CDC)
Healthy Diet: Eat a diet rich in fruits, vegetables, and whole grains. These foods contain vitamins, minerals, and fiber that can help protect your colon. Limit red and processed meats, as they have been linked to a higher risk of colon cancer.
Exercise: Get regular physical activity. Aim for at least 150 minutes of moderate exercise (like brisk walking) or 75 minutes of vigorous exercise (like running) each week. Exercise helps keep your colon healthy.
Maintain a Healthy Weight: Being overweight or obese increases your risk of colon cancer. Maintain a healthy weight through a balanced diet and regular exercise.
Limit Alcohol: If you drink alcohol, do so in moderation. Limiting alcohol can reduce your risk. For men, that means up to two drinks a day, and for women, one drink a day.
Quit Smoking: Smoking is a risk factor for colon cancer. Quitting smoking can significantly lower your risk and improve your overall health.
Regular Screenings: Colonoscopies and other screening tests are essential, especially if you’re over 50 or have a family history of colon cancer. These tests can detect and remove polyps before they become cancerous, or catch cancer at an early, more treatable stage.
Know Your Family History: If you have close family members with colon cancer, inform your doctor. Your risk may be higher, and you might need to start screenings earlier.
Manage Chronic Conditions: If you have conditions like diabetes or inflammatory bowel disease (IBD), work closely with your healthcare team to manage them effectively. Controlling these conditions can help reduce your risk.
Vaccination: In some cases, infections like human papillomavirus (HPV) can increase the risk of colon cancer. If applicable, discuss HPV vaccination with your healthcare provider.
Limit Processed Foods: Processed foods often contain unhealthy fats and additives. Try to limit your consumption of these foods and opt for whole, natural options.
Hydration: Staying well-hydrated by drinking plenty of water is important for digestive health. Adequate hydration may help reduce your risk of colon cancer.
Stress Management: Chronic stress may affect your overall health. Practicing stress-reduction techniques like meditation or yoga can be beneficial.
Stay Informed: Keep yourself informed about colon cancer and its risk factors. This will help you make informed choices and understand when you should seek medical advice or screenings.
Preventing colon cancer is about adopting a healthy lifestyle, staying informed, and working with your healthcare team. Remember that while these steps can reduce your risk, there are no guarantees, so regular screenings are crucial for early detection and effective treatment if needed. If you have questions or concerns about colon cancer prevention, consult your healthcare provider for personalized guidance.
Medical History and Physical Exam: Your doctor will start by asking about your medical history, including any symptoms you may be experiencing. They will then perform a physical examination to check for signs of colon cancer.
Blood Tests: Blood tests may be done to check for anemia (a low red blood cell count) or to evaluate how well your liver and kidneys are functioning. Colon cancer can sometimes affect these blood markers.
Stool Tests: These tests are done to look for blood in your stool, which can be a sign of colon cancer. The two common types of stool tests are fecal occult blood test (FOBT) and fecal immunochemical test (FIT).
Colonoscopy: This is one of the most common tests for diagnosing colon cancer. During a colonoscopy, a thin, flexible tube with a camera at the end is inserted into your rectum and moved through your colon. This allows the doctor to see the inside of your colon, check for polyps or cancer, and even remove polyps if they’re found.
Sigmoidoscopy: Similar to a colonoscopy, this test examines the lower part of your colon. It’s less invasive than a full colonoscopy and doesn’t require as much preparation, but it can miss some cancers higher up in the colon.
Virtual Colonoscopy (CT Colonography): This test uses X-rays and a computer to create detailed images of the colon. It’s less invasive than a traditional colonoscopy but still requires bowel preparation.
Barium Enema: This test involves filling the colon with a contrast material (barium) and taking X-rays. It can help identify abnormalities in the colon’s shape, although it’s less commonly used today.
Biopsy: If a suspicious area is found during a colonoscopy, a small piece of tissue (biopsy) may be removed for examination in the lab. This can confirm whether cancer is present.
Imaging Tests: These tests, such as CT scans, MRI, and PET scans, can help determine the stage of the cancer and if it has spread to other parts of the body.
Genetic Testing: Some people may undergo genetic testing to determine if they have specific genetic mutations that increase the risk of colon cancer. This can be particularly important if you have a family history of the disease.
The combination of these tests and procedures helps doctors diagnose colon cancer, determine its stage (how far it has spread), and develop a treatment plan tailored to your specific situation. If colon cancer is detected, early diagnosis and treatment can greatly improve the chances of successful outcomes. It’s important to consult with your healthcare provider if you have any symptoms or risk factors associated with colon cancer.
