Colorectal Cancer Frequently Asked Questions

How common is colorectal cancer?

Colorectal cancer is actually the third most common type of cancer in men and women; more than 100,000 people are diagnosed with it each year.

What are the risk factors associated with colorectal cancer?

  • There are many risk factors identified with colorectal cancer, including:
  • Age – 90% of colorectal cancer diagnoses are in patients over 50.
  • Diets low in fruits and vegetables
  • Diets high in red meat
  • Obesity
  • Lack of physical activity
  • Excessive drinking
  • Excessive smoking
  • A history of Crohn’s Disease or ulcerative colitis
  • A history of colorectal cancer or colon polyps

Is there a connection between food intolerance, including lactose intolerance, and a person’s risk for colorectal cancer?

At this time there is very little hard data suggesting a connection between lactose intolerance and a person’s risk for colorectal cancer. That said, new literature suggests that the gut’s microflora may play a role in colorectal health and that probiotic therapy is healthy.

Is irritable bowel syndrome (IBS) a risk factor?

Although IBS is associated with abdominal cramping, pain, diarrhea, and other functional gut problems, there is no link between IBS and a person’s risk for colorectal cancer.

Is colorectal cancer treated only with surgery?

Surgery is certainly a common approach to colorectal cancer treatment but it is not the only one. Radiation therapy and other treatment options may be considered.

What affects the use of radiation therapy as a colorectal cancer treatment?

There are many factors that doctors consider when determining whether or not radiation therapy is recommended for a particular patient’s treatment. These factors include the size and location of the tumor and the general health of the patient.
