Colorectal Cancer


Colorectal cancer starts in the large intestine (colon) or rectum.


Call 911 for any of the following:

  • Your arm or leg feels warm, tender, and painful. It may look swollen and red.
  • You suddenly feel lightheaded and short of breath.
  • You have chest pain when you take a deep breath or cough.
  • You cough up blood.

Contact your oncologist if:

  • You have a fever.
  • You cannot control your diarrhea or constipation.
  • You vomit multiple times and cannot keep any food or liquids down.
  • Your pain is worse or does not go away after you take your pain medicine.
  • You see blood in your bowel movements.
  • You have questions or concerns about your condition or care.


  • Antinausea medicine may be given to calm your stomach and prevent vomiting.
  • Prescription pain medicine may be given. Do not wait until the pain is severe before you take this medicine.
  • Take your medicine as directed. Call your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your oncologist as directed:

You will need to see your oncologist for ongoing treatment and follow-up. Your healthcare provider may want you to have a yearly colonoscopy to check for colorectal cancer. Write down your questions so you remember to ask them during your visits.

Get screened as directed:

Your healthcare provider may want you to have a yearly colonoscopy to check for colorectal cancer. Screening is recommended for all men and women older than 45 to 50 years. You may need to get screened earlier if you have colon disease or a family history of colorectal cancer.

Do not smoke:

Nicotine can damage blood vessels and make it more difficult to manage your colorectal cancer. Smoking also increases your risk for new or returning cancer and delays healing after treatment. Do not use e-cigarettes or smokeless tobacco in place of cigarettes or to help you quit. They still contain nicotine. Ask your healthcare provider for information if you currently smoke and need help quitting.

Eat healthy foods:

Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. You may need to change what you eat during treatment. Do not eat foods or drink liquids that cause gas, such as cabbage, beans, onions, or soda. A dietitian may help to plan the best meals and snacks for you.

Limit or do not drink alcohol as directed:

Men should limit alcohol to 2 drinks per day. Women should limit alcohol to 1 drink per day. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.

Drink liquids as directed:

Ask how much liquid to drink each day and which liquids are best for you. If you have nausea or diarrhea from cancer treatment, extra liquids may help decrease your risk for dehydration.

Exercise as directed:

Ask about the best exercise plan for you. Exercise may improve your energy levels and appetite.
