Colorectal cancer: Signs, symptoms, and causes

What is colorectal cancer?

Colorectal cancer occurs when abnormal cells in the colon or rectum grow uncontrollably and form a tumor. It usually starts as small, noncancerous polyps (growths) that can turn into cancer over time. Not all polyps become cancer, but some types, especially adenomatous polyps, have a higher risk.

Symptoms and Signs of colorectal cancer

Colorectal cancer may not show symptoms in its early stages, which is why regular screening is important. Here we mentioned some possible signs that may include.

• Changes in bowel habits (e.g., diarrhea or constipation lasting more than two weeks)
• Feeling that your bowel doesn’t empty completely
• Blood in the stool or rectal bleeding
• Narrow or thin stools
• Persistent abdominal discomfort, such as cramps, gas, or pain
• Fatigue or weakness without a clear reason
• Unexplained weight loss
• Unexplained anemia (low red blood cell count)
• Feeling bloated or full even after a small meal
• Nausea or vomiting
• Abdominal pain, especially in the lower abdomen

Note: 1- If you notice any of these symptoms, especially if they persist, it’s important to consult with a colorectal expert doctor as early as possible.
Note: 2- The severity of symptoms can vary based on the size and location of the tumor in the colon or rectum.

Causes and risk factors of colorectal cancer

There’s no single cause of colorectal cancer, but several risk factors can increase your chances of developing the disease:

1. Age: Most colorectal cancer cases occur in people over 50 years old, but it can happen even in teenagers.
2. Family history: If you have close relatives with colorectal cancer or polyps, your risk increases.
3. Lifestyle factors:
   • Low-fiber, high-fat diet
   • Lack of physical activity
   • Smoking and heavy alcohol use
   • Obesity
4. Medical conditions:
   • Inflammatory bowel diseases like Crohn’s disease or ulcerative colitis
   • Type 2 diabetes
5. Genetic conditions: Hereditary syndromes such as Familial Adenomatous Polyposis (FAP) or Lynch syndrome can raise the risk significantly.

How to minimize your risk?

You can reduce your chances of developing colorectal cancer by adopting healthy habits:

• Eat a balanced diet rich in fruits, vegetables, and whole grains
• Stay physically active
• Avoid tobacco and limit alcohol
• Maintain a healthy weight
• Go for regular screenings (like a colonoscopy), especially after age 50 or earlier if you have a family history
• Discuss genetic testing if colorectal cancer runs in your family

When to see a doctor?

It’s important not to ignore potential warning signs of colorectal cancer. You should see a doctor if you experience any of the following symptoms, especially if they persist for more than a few days:

• Especially blood in the stool.
• Any change in your bowel habit.
• Unexplained weight loss.
• Ongoing digestive issues.

Note: Don’t delay seeking medical advice. Early detection is key to successful treatment.
