This cancer often begins as small, non-cancerous growths called polyps. Over time, some polyps can turn into cancer if they are not found and removed.
Common symptoms of colorectal cancer include changes in bowel habits, such as diarrhea or constipation, blood in the stool, and unexplained weight loss. Some people may also experience abdominal pain or cramping.
Early detection is key to successful treatment of colorectal cancer. Doctors usually recommend regular screenings, like colonoscopies, to find polyps before they become cancerous. If caught early, colorectal cancer can often be cured through surgery, chemotherapy, or radiation therapy.
Maintaining a healthy diet, exercising regularly, and avoiding smoking can also help lower the risk of developing colorectal cancer. It's important to see a doctor if you notice any unusual symptoms, as early treatment leads to the best outcomes.
Symptoms of colorectal cancer may not appear right away, but when they do, they can include:
Changes in bowel habits: Diarrhea, constipation, or a change in stool consistency.
Blood in stool: Bright red or dark stools.
Abdominal discomfort: Cramps, gas, or pain.
Weakness or fatigue: Feeling tired without reason.
Unexplained weight loss.
A feeling that your bowel doesn't empty after a bowel movement.
Note: If you experience any of these symptoms, especially blood in your stool, consult a doctor immediately.
Colorectal cancer happens when healthy cells in the colon or rectum develop changes (mutations) in their DNA. These cells grow uncontrollably, forming a tumor. The exact cause isn't always known, but some factors that increase risk include:
Genetic mutations: Changes passed down through families.
Lifestyle factors: Poor diet, smoking, and alcohol use.
Inflammation: Chronic conditions, such as inflammatory bowel disease (IBD), increase the risk of inflammation.
If you notice blood in your stool or unexplained changes in bowel habits.
Persistent abdominal pain or cramps that don't go away.
Fatigue and weakness that don't improve with rest.
Unexplained weight loss.
Seeing a doctor early can help diagnose cancer at a more treatable stage.
Several tests can help diagnose colorectal cancer:
Colonoscopy: A flexible tube with a camera is used to examine the entire colon and rectum. Polyps or abnormal areas can be biopsied.
Stool tests: These examine your stool for hidden blood or abnormal DNA.
CT Colonography: A CT scan that provides images of the colon and rectum.
Biopsy: If a suspicious area is identified, a small tissue sample is taken and analyzed for the presence of cancer.
Do's:
Eat a healthy diet: Focus on fruits, vegetables, whole grains, and fiber.
Exercise regularly: Aim for at least 30 minutes of activity most days.
Get screened: Regular screening, especially after the age of 50, helps detect polyps before they develop into cancer.
Maintain a healthy weight: Being overweight increases your risk of cancer.
Limit alcohol: If you drink, do so in moderation.
Don'ts:
Don't smoke: Smoking increases your risk of many types of cancer, including colorectal cancer.
Limit red and processed meats: These have been linked to a higher risk of colorectal cancer.
Don't ignore symptoms: Early detection is key, so if you experience any warning signs, see a doctor.
