Who's at Risk for Colon Cancer?
The third cancer that is most diagnosed in United States is colon (or colorectal) cancer. Colon cancer is preventable and in most incidences, highly treatable especially when it is early, hence the importance of regular screening.
Colon cancer is ranked among the most prevalent cancer in the U.S. It can occur to anyone, although there are risk factors that may expose one to it. We are sure that in Gastrodoxs we can think that you will take measures as soon as you know risks.
This resource describes in layman terms who is the most susceptible to colon cancer. You will also find out how your age, family history, diet, polyps, and some diseases have an impact on your likelihood. We are also going to discuss the contribution of genetics, lifestyle, screening tips, and the sources of care in Houston. Let's jump in!
1. Age and Family History
Age Increases Risk
Risk goes up after age 45.
9/10 of the cases occur in individuals above 50.
The American Cancer Society prescribes screening at 45 years of age to most adults.
Family History Matters
You are at risk twice with a colon cancer patient being either a sibling, parent or child.
The risk is more in case they were diagnosed below age 50 or when more than one of their relatives had a diagnosis.
Dr. Bharat Pothuri says: The family history is one of the most powerful predictors. You might have to take a screening at an earlier age and frequency in case your close relatives had colon cancer.
2. Personal History of Polyps
What Are Polyps?
Polyps are little growths within the colon. The majority of them are not harmful, but certain forms, such as adenomatous polyps, may develop into cancer.
Higher Risk with Polyps
The presence of adenomatous polyps puts you at risk.
Physicians examine the size, count and type of polyps to schedule the frequency of screening.
Follow-Up Timing:
Minor or low polyps: repeat colonoscopy within 5 years.
Polyps greater or more than 1: in 3 years.
High risk types: perhaps in 1-3 years.
Dr. Pothuri says: it is best to prevent cancer by catching polyps at an early age. It tells a story in your colonoscopy report do not ignore it.
3. Diet and Colon Cancer
Diet Makes a Big Difference
Your daily diet has an impact on your colon with time. There are foods which increase risk, others which decrease it.
Foods That Increase Risk
Bacon, sausage, deli meat Processed meats (bacon, sausage, deli meat)
Large amounts of red meat
High-fat, low-fiber diets
Foods That Lower Risk
Fruits and vegetables that contain a lot of fiber.
Cereals such as brown rice and whole wheat.
Beans, lentils, and legumes
Hint: Replace grilled fish with hot dogs. Add fresh salad to meals.
4. Colon Cancer and Inflammatory Bowel Diseases (IBD)
What Is IBD?
IBD consists of ulcerative colitis and Crohns disease both of which cause chronic inflammation of the digestive tract
Why IBD Raises Risk
Inflammation is damaging to colon cells in the long run.
The longer disease duration = the greater the risk of cancer.
Risk is further increased by more widespread inflammation.
Dr. Pothuri says: It is important to treat inflammation and have colonoscopies regularly. We collaborate with GI specialists throughout the Houston area to treat our IBD patients.
5. Syndromes of Hereditary Colon Cancer
What Is Genetic Counseling?
Genetic counseling examines the family medical history. You can be sent to genetic testing.
Common Genetic Syndromes
Lynch syndrome
Familial adenomatous polyposis (FAP)
Peutz-Jeghers syndrome and MUTYH-associated syndrome
Why It Helps
Identify high-risk patients
Begins screening at earlier age (as young as 20s)
Helps prepares prevention or surgery
Dr. Pothuri says: genetic counseling assists an individual in making wise decisions. It informs us when to screen, and what action to follow.
6. Lifestyle and Environment
Lack of Exercise and Overweight
Excessive idleness increases the risk of colon cancer.
Additional belly fat leads to additional inflammation.
Smoking and Alcohol
The long term smoking is a risk.
The excessive consumption of alcohol increases your risk as much as 50 percent.
Easy Lifestyle Tips
Have at least 150 minutes of exercise every week.
Restrict alcohol (1alcohol/day in women, 2 in men).
Houston has programs that can help people to quit smoking.
7. Screening: When and How
For Most Adults
Colonoscopy within 10 years beginning at 45 years of age
Alternatives: stool tests once a year, flexible sigmoidoscopy once every 5 years
For Higher-Risk Groups
Family history: beginning 10 years before the diagnosis of the first relative
Polyps: subsequent according to the recommendation of the GI doctor
Colon cancer is severe and avoidable. When you are informed about the risks, you eat well, get screened, and be active, you will be in charge of your health.

At what age should I be screened with colon cancer?
Begin at 45 when you are averagely at risk. And with family history, begin earlier ¹around 10 years prior to the time your family member was diagnosed.
How frequently should I get a colonoscopy when I already had polyps?
It depends. Low-risk polyps: every 5 years. High-risk ones: every 1-3 years.
Would I ever meet with a genetic counselor without a known syndrome?
Yes, in case a number of close relatives had colon or related cancers.
Is diet sufficient in the prevention of colon cancer?
No, but it helps. Consume food rich in fiber and restrict red or processed meat. This is to be combined with exercise and screening.
Is ulcerative colitis necessarily cancer causing?
Not always. However, the risk increases with increased and prolonged disease. Regular checkups are key.
Are stool tests good enough?
They are useful yet fall short. A positive outcome normally implies that you should have a colonoscopy.
Is being overweight really a risk to me?
Yes. Especially belly fat. It causes increased inflammation, and this can result in cancer.
Will I be able to receive screening in Houston without insurance?
Yes. There are cheaper alternatives at Harris health and other programs.
But what about family history of colon cancer?
Tell your doctor. You might require previous examination, and genetic counseling.
Where do I get any specialist in Houston?
Experiment with Houston Methodist or MD Anderson. We have a Resources page at Gastrodoxs.com too.
