Save Yourself from Colorectal Cancer

So, what is Colorectal Cancer?

Colorectal Cancer or well-known as Colon Cancer develops in the colon or the rectum, also known as the large intestine. The colon and rectum are parts of the digestive system, also called the gastrointestinal system. The digestive system processes food for energy and rids the body of solid waste (fecal matter or stool). After food is chewed and swallowed, it travels through the esophagus to the stomach. There it is partially broken down and sent to the small intestine, where digestion continues and most of the nutrients are absorbed. Cancer develops much less often in the small intestine than in the colon or rectum. The small intestine joins the large intestine in the lower right abdomen. The small and large intestine are sometimes called the small and large bowel. The first and longest part of the large intestine is the colon, a muscular tube about 5 feet long. Water and mineral nutrients are absorbed from the food matter in the colon. Waste or feces left from this process passes into the rectum, the final 6 inches of the large intestine, and is then expelled from the anus.


Prevention of Colorectal Cancer

Colorectal Cancer is one of the most common kind of cancer, it is scary because it can kill anyone but then there’s the good news: It can be prevented. Seventy-five percent of all cases could be avoided by things you can do, these things might help lower your risk, such as changing the risk factors that you can control. To help protect yourself and lower the risk for your loved ones from the disease, follow these ten colon cancer prevention tips. Start with one or two and build from there. It’s your health. Take control.

1. Get Screened

Getting regular screening tests for colon cancer is the single best way to protect yourself from the disease. It can catch cancer early, when it’s most treatable, and help prevent the disease by finding abnormal growths called polyps that can turn into cancer.

There are a number of effective screening tests for colon cancer. Some are easy to do but need to be done more often. Others are
more involved but need to be done less often. Which test you have depends on your personal preferences and medical history. A doctor can help you decide.

Most people begin getting tested at age 50. People with a family history of colon cancer or other important risk factors may begin testing at younger ages and get tested more often.

Choose one of these recommended screening options. If a test finds anything suspicious, a follow-up colonoscopy is usually needed.

Fecal Occult Blood Test (FOBT)/Fecal Immunochemical Test (FIT)

How often: every year

Tests that look for hidden blood in the stool, which can be a sign of cancer. The test is quick and easy. You just take small samples of your stool at home, which are then sent to a lab to be tested.



How often: every 10 years

A small flexible tube with a camera at the end is used to examine the full length of the inside of the colon. You are sedated for the test, so you need a ride home afterward. If the exam finds polyps or other suspicious growths, they can be removed during the test.


Flexible Sigmoidoscopy

How often: every five years

An exam similar to a colonoscopy that uses a small flexible tube to examine the lower part of the colon (the sigmoid). You don’t need to be sedated for a sigmoidoscopy.


Virtual Colonoscopy

How often: every five years

A type of CT scan that creates a precise 3-D image of the inside of the colon. During the test, a small tube is inserted into the rectum to gently inflate the colon with air. The scan itself takes just a few minutes.

2. Maintain a Healthy Weight

Except for smoking, nothing else raises the overall risk of cancer more than being overweight. At least 11 different cancers have been linked to weight gain and obesity, including colon cancer. An ideal goal is to weigh around what you did when you were 18 years old. Realistically, if you’ve put on weight, the first goal is to stop gaining weight, which has health benefits by itself. Then, for a bigger health boost, slowly work to lose some pounds.

3. Don’t Smoke

It hardly needs saying anymore, but not smoking is the single best thing you can do for your health. On top of raising the risk of serious diseases like heart disease, stroke and emphysema, smoking is a major cause of at least 14 different cancers, including colon cancer. If you do smoke, quitting has real benefits, which start shortly after your last cigarette. Talking to a doctor can double your chance of success.

4. Be Physically Active

It’s hard to beat regular activity. It lowers the risk of many serious diseases, including colon cancer, and provides a good mental boost. Any amount of physical activity is better than none, but it’s good to aim for around 30 minutes or more of moderate activity each day. Choose things you enjoy, like brisk walking, cycling, dancing or gardening.

5. Drink Only Moderately, if at All

Alcohol is a strange thing when it comes to health. It’s heart-healthy in moderation but can increase the risk of colon and other cancers at even low levels. So what does this mean? If you drink moderately (up to one drink per day for women, two per day for men), there’s likely no reason for you to stop. If you don’t drink, though, there’s no reason for you to start. Heavy drinkers should try to cut down or quit.

6. Limit Red Meat, Especially Processed Meat

Eating too much red meat – like steak, hamburger and pork – increases the risk of colon cancer. And processed meats – like bacon, sausage and bologna – raise risk even more. Try to eat no more than three servings each week. Less is even better.

7. Get Enough Calcium and Vitamin D

There is good evidence that getting enough calcium and vitamin D can help protect against colon cancer. Shoot for 1,000 to 1,200 milligrams per day of calcium and about 1,000 international units (IU) per day of vitamin D. Some groups recommend testing for vitamin D deficiency, especially in those with increased risk of low levels, such as those living in northern parts of the country as well as elderly people, very overweight people and people with darker skin.

8. Consider a Multivitamin With Folate

A daily multivitamin is a good nutrition insurance policy that can also help protect against colon cancer. In addition to calcium and vitamin D, multivitamins contain folate, which has been shown in numerous studies to lower the risk of colon cancer. Avoid mega-dose vitamins. A standard multivitamin is all you need.

9. Consider Genetic Counseling

People who carry genetic mutations linked to hereditary colon cancer are the most likely to develop the disease. If someone in your family has FAP or HNPCC, you should seriously consider adding genetic counseling to your colon cancer prevention plan.

10. Reduce Radiation Exposure.

Can radiation exposure give you cancer? The short answer is yes. According to the U.S. Department of Health and Human Services, colon cancer has been caused by doses of about 1,000 millisieverts (mSv). Exposure to less than 200 mSv can cause leukemia and cancer of the thyroid, breast, and lung. And liver cancer can be caused by exposure to less than 100 mSv of radiation.

Other Important Risk Factors for Colon Cancer

Though colon cancer is very preventable, there are still a number of important risk factors that people can’t control. Knowing which ones apply to you can help you understand your risk and take steps to lower it. If you feel you’re at high risk, talk to a doctor or health professional.

These can increase colon cancer risk:

  • Older age, especially 60 years or older
  • Family history of colon cancer
  • Inflammatory bowel disease
  • Being tall (5 feet 8 inches or taller for women; 5 feet 11 inches or taller for men)
