One of the most dangerous things about most cancers is that even with a successful course of treatment, there is a chance that the cancer can come back. This is because the genetic changes that lead to cancer can also affect the nearby cells and tissues. Researchers are working to discover effective ways of preventing cancer recurrence. Depending on the type of cancer, there are various ways to lower the risk of the cancer coming back.
Step 1
Get frequent physical exams. The American Cancer Society recommends that patients who have had their cancer successfully treated have a full physical exam every three to six months for the first two years, and then every six months thereafter. These exams may include blood tests to look for indications of cancer recurrence as well as imaging studies (such as X-rays or MRIs) to screen for recurring cancer.
Step 2
Exercise. The Mayo Clinic reports that cancer survivors are encouraged to do at least 30 minutes of exercise five times per week. Cancer survivors who follow an exercise program feel stronger, experience less fatigue and anxiety, and have stronger immune systems. The Mayo Clinic also reports that regular exercise may reduce the risk of cancer recurrence.
Step 3
Eat a healthy diet. Although there have been studies that examine the effects of specific diets on the rate of cancer recurrence, there is not enough information to determine the effects of diet on cancer. However, eating a diet that is low in fat and has lots of whole grains, fruits and vegetables will help give your body the nutrients it needs to stay strong.
Step 4
Avoid smoking and alcohol. Tobacco smoke has a number of carcinogens that can increase your risk of developing several different cancers, as does alcohol. Consequently, tobacco and alcohol use increases the chance of cancer recurring in a number of organs, including the esophagus, lungs, stomach and liver.
Step 5
Talk to your doctor about options for cancer prevention. Depending on the type of cancer you had, there may be medications that you can take to lower your risk of having the cancer come back (such as tamoxifen for breast cancer). Alternately, you may be able to surgically remove any tissue that is "at-risk" for cancer recurrence.
