Rectal Cancer Q & A

What is rectal cancer?

Rectal cancer is a condition affecting the rectum, which is the last part of your large intestine or colon. Colon cancer is closely related to rectal cancer, and they’re often referred to collectively as colorectal cancer. However, while they share many similarities, colon and rectal cancers require different treatments.

Rectal cancer develops when cells in your rectum mutate and their DNA changes. These abnormal cells continue to multiply, forming a tumor and eventually spreading to other tissues and organs.

What causes rectal cancer?

The reasons why rectal cancer develops isn’t always clear, but there are genetic conditions, called hereditary nonpolyposis colorectal cancer (HNPCC, or Lynch syndrome) and familial adenomatous polyposis (FAP), that can cause rectal cancer. If you have a family history of these conditions, it’s worth having a genetic test to see if you’re affected.

There are also risk factors that make your chances of developing rectal cancer higher, including:

  • Being over 50
  • Being African-American
  • Having ulcerative colitis
  • Having Crohn's disease
  • Family history
  • Sedentary lifestyle
  • Type 2 diabetes
  • Being obese
  • Smoking
  • Drinking alcohol regularly

Colorectal cancer rates are higher in people whose diets are high in red meat and low in vegetables.

What are the symptoms of rectal cancer?

Common symptoms of rectal cancer include:

  • Diarrhea or constipation
  • Dark blood in your stool
  • Mucus in stool
  • Narrow stool
  • Abdominal pain
  • Painful bowel movements
  • Anemia
  • Unexplained weight loss
  • Weakness or fatigue

You might also have the feeling that your rectum isn’t empty after a bowel movement.

How is rectal cancer treated?

Prevention is the best defense against rectal cancer, and the most effective form of prevention is to have a colonoscopy. During this screening, your surgeon at Wellness Oncology and Hematology passes a slim, flexible tube called a colonoscope into your rectum, which sends back images of the inside of your colon and rectum to a monitor.

Using these images, your surgeon can identify and remove any polyps, which are small, mainly benign growths. Rectal cancer typically develops when one of these polyps turns cancerous, so removing them prevents cancer from taking hold.

Treating rectal cancer might involve a combination of approaches. Patients have surgery to remove cancer wherever possible, along with chemotherapy, which kills cancer cells using drugs, and radiation therapy, which kills cancer cells using X-rays or protons.
