What can you expect if you’re scheduled for a colonoscopy?
The night before, you’ll need to complete a bowel prep, which involves drinking a liquid medication that causes short-term diarrhea. The goal of bowel prep is to clean out your lower intestine so the lining of your colon is easier to see on camera. You may also need to avoid solid foods ahead of time. Most people are instructed to only consume clear liquids like chicken broth and Jell-O the day before.
Right before your colonoscopy, you’ll be given a sedating medication, or a drug that will make you feel calm and sleepy. You may still be groggy afterwards, so bring a friend or family member along to help you get home safely.
If you’re at an average risk for colon cancer, your next colonoscopy should be done in ten years.
How colon cancer is treated
Most labs will know your biopsy results within two weeks, but many will notify you sooner. If your biopsy reveals that you have cancer, the treatment that you receive will depend on how aggressive the cancer is.
Small tumors may be completely removed during your initial colonoscopy. If it’s not possible to completely remove the cancer at that point, you may need surgery as well. Your surgeon will take samples of lymph nodes during surgery to determine whether the cancer has spread outside of your colon.
If the cancer has reached your lymph nodes, he or she may recommend chemotherapy. Chemotherapy is a type of medication that kills off cancer cells that may be left in your body after surgery. Chemo for colon cancer typically involves intravenous medication that’s given in a series of doses, spread out over about six months.
Ways to lower your risk for colon cancer
There’s no surefire way to prevent colon cancer, but there are a few lifestyle changes that can help lower your risk:
Quit smoking: Follow Sharecare’s ten-step quit smoking plan to help you kick the habit.
Eat less red meat: “There’s growing evidence that red meat and smoked foods, which have been processed with preservatives called nitrites, can increase your risk for colon cancer,” says Goldin. Set a goal to cook a few vegetarian meals each week. Add legumes like beans, lentils and chickpeas to dishes instead of meat to help you feel full and satisfied.
Get enough exercise: Aim for 150 minutes of moderate exercise or 75 minutes of vigorous exercise each week. Keeping the weight off—especially around your midsection—has been shown to reduce colon cancer risk.
Ask your HCP about an aspirin regimen: A growing number of studies have found that people who take anti-inflammatory medications like aspirin and naproxen are less likely to develop colon cancer. But not everyone should take these drugs, so don’t add them to your med list without talking to your HCP first.
The most important thing you can do to avoid a late-stage colon cancer diagnosis is to follow routine screening guidelines,
“Think about the costs of treatment, the worry and everything you’d go through with a colon cancer diagnosis,” says Goldin. “If you detect polyps early and remove them before they become cancer, you can prevent a great deal.
