What you need to know about colorectal cancer

Colorectal cancer. Those are two words no one wants to hear. According to the American Cancer Society, colorectal cancer is the third most common cancer in the United States with nearly 102,480 new cases of the disease diagnosed in 2013. Fortunately, the death rate from colorectal cancer has been dropping over for more than 20 years due to early screenings and improved treatments.

Undergoing testing to diagnose colorectal cancer may be necessary because of abnormal results from a screening exam or if there are symptoms of the disease, such as a change in bowel habits, abdominal pain, weakness, rectal bleeding or blood in the stool.

Diagnosis may begin with a complete medical history and physical examination. Endoscopic tests to check for colorectal polyps also may be necessary, including a sigmoidoscopy or colonoscopy (procedures used to see inside the colon and rectum), and imaging tests such as a barium enema, double contrast barium enema or virtual colonoscopy. A biopsy is done on any abnormal-looking tissues that are removed during a colonoscopy to confirm the diagnosis of colorectal cancer.

Other imaging tests may be required to determine if a suspicious area is cancerous, learn if the cancer has spread or find out if treatment has been effective. These tests include computed tomography, ultrasound, magnetic resonance imaging, positron emission tomography and angiography.

Once colorectal cancer had been diagnosed, treatment will be determined based on the stage and type of cancer, how far it has spread, overall health, side effects of treatment and long-term prognosis. Surgery usually is recommended for early stage colon cancer. The procedure calls for the removal of part of the colon and nearby lymph nodes. Some stage 0 or early stage 1 tumors can be taken out by removing the base of the polyp or the superficial cancer and a small margin of surrounding tissue.

Colorectal cancer also may be treated with three different types of radiation therapy, which use high-energy rays or particles to destroy cancer cells.

  • External-beam radiation therapy focuses radiation on the cancer from outside the body;
  • Endocavitary radiation therapy delivers radiation through a hand-held device placed into the anus; and
  • Internal radiation therapy (brachytherapy) involves placing small pellets of radioactive material next to or directly into the cancer.

Chemotherapy, which involves administering drugs either into a vein or orally, can be part of a colorectal cancer treatment plan as well. Neoadjuvant chemotherapy may be given along with radiation before surgery to try to shrink some rectal cancers. Adjuvant chemotherapy is given after surgery in case the cancer returns.

It is important to discuss potential side effects of treatment with your doctor. Most side effects should decrease after treatment, but steps can be taken to reduce or relieve them.

7 Types of Foods That May Help You Prevent Colon Cancer

According to research conducted by the American Cancer Society, colorectal cancer is the third most common type of cancer in the United States, both for men and women. Typical symptoms of this disease include rectal bleeding, blood in the stool, abdominal cramping or pain, changes of stool shape, changes in bowel habits, anemia and weight loss.

What is Colon Cancer?

Colorectal cancer is also known as colon cancer, bowel cancer or rectal cancer. Physicians commonly identify it depending on the where the tumor begins. Colorectal cancer starts when tumors or polyps develop in the lining of the colon or the end part of the large intestine which is called the rectum.

The tumors and polyps, when not removed earlier, can grow over time and become cancerous. They can also spread in the other layers of the large intestine, making the disease more dangerous.

Risk Factors

Some risk factors for colon cancer include modifiable, hereditary and medical factors such as:

  • Family or personal history of colorectal cancer
  • High consumption of red and/or processed meat
  • Long-term smoking
  • Long-term use of nonsteroidal anti-inflammatory drugs
  • Low calcium intake
  • Low intake of fruits and vegetables
  • Low intake of whole-grain fiber
  • Moderate to heavy alcohol consumption
  • Physical inactivity
  • Personal history of chronic inflammatory bowel disease
  • Obesity
  • Type 2 diabetes

Best Foods for Your Colon

Your colon needs the right amount of omega 3-fatty acids, vitamin D, calcium and flavonoids to prevent tumors from growing. Dietary fiber is also essential as it promotes regular bowel movement and helps limit bacteria build up. Below are some food groups that can help you prevent colon cancer inception.

  1. Fish

    Fresh fish high in omega-3 fatty acids can help reduce inflammation in the body. In fact, a research team from Vanderbilt University found out that women who eat three servings of fish per week reduced their risk of developing colon polyps at around 33 percent.

    Your best picks would be baked or smoked salmon, tuna and sardines as they are also rich in vitamin D and calcium.

  2. Fruits

    Fruits are generally rich in antioxidants, fiber and species-specific phytochemicals that can help in protecting you from digestive problems.

    Apples, blackberries, bananas, blueberries, oranges, pear and raspberries are some of the best sources of fiber.

  3. Non-starchy vegetables

    For overall health, the rule of thumb is to fill two-thirds of your plate with plant-based food as they are rich in fiber, vitamins, minerals and phytochemicals. However, to lower your risk of having type 2 diabetes, another factor that can lead to colon cancer, the American Diabetes Association suggests that you emphasize on non-starchy vegetables.

    Try to eat at least 3-5 servings of non-starchy vegetables per day, including lettuce, kale, cucumbers, artichokes, broccoli, cabbage, carrots, cauliflower, celery, okra and spinach.

  4. White Meat

    Protein is crucial for muscle development, growth of tissues and more. And since you need to limit your red meat consumption, your healthier alternatives would be skinless chicken or turkey.. Eggs are a good option, too.

  5. Whole grains

    Whole grains are another fiber-packed food group that you can perfectly match with fish, eggs and white meat. Your healthiest options would be brown rice, barley, oatmeal and quinoa.

  6. Nuts

    Eating at least two, one-ounce servings of nuts a week can help keep your blood sugar and insulin levels low, reducing your risk of having type 2 diabetes. Since they are also packed with healthy fatty acids, fiber and flavonoids, nuts can also help decrease your chances of having colon cancer.

    Your best picks would be tree nuts such as almonds, cashews, hazelnuts, pecans, pistachios and macadamia nuts.

  7. Beans and Legumes
    Soybeans, lentils, peas, pinto beans, black beans and kidney beans are a great source of protein, fiber, vitamin B and vitamin E. Aside from the benefits and protection they provide to your colon, beans and legumes can also help reduce cholesterol and blood sugar levels.

Final Thoughts

Having healthy food choices play a vital role in colon cancer prevention. While this guide gives you an insight on what types of food to limit and what to eat more, it’s still best to visit a physician for colorectal cancer screening as this disease rarely causes symptoms until it’s in a more serious stage.

All the best!
