Exercise Your Way to a Healthier Colon
What can you do to prevent colon cancer? Studies show that certain behaviors are associated with colon cancer. For example, the risk of developing colon cancer increases if you are physically inactive, obese, drink excessive amounts of alcohol, or eat a diet high in red or processed meat, refined grains, and fats, especially those from animal sources. A reader asks: I'd like to make some lifestyle changes to reduce my risk of colorectal cancer. Will exercise help? Johns Hopkins responds … More...

The Outlook for Metastatic Colorectal Cancer
'In the past, chemotherapy was the only option for patients with advanced colorectal cancer, which often spreads to the liver. But now, aggressive approaches to surgery executed by multidisciplinary teams that bring together colorectal and liver specialists are improving survival and even curing many of these patients,' observes Michael A Choti, M.D., Director of the Johns Hopkins Colon Cancer Center.

Colon Cancer Surgery: Open or Laparoscopic?
Colon cancer operations are low risk, and in recent years major surgical advances, like the increasing use of minimally invasive laparoscopic techniques, have been helping patients live longer with fewer side effects. In this excerpt of an article from our Health After 50 newsletter, Michael A. Choti, M.D., the Jacob C. Handelsman Professor of Surgery at Johns Hopkins and Director of the Johns Hopkins Colon Cancer Center talks about colon cancer surgery. More...

Clinical Trial Terminology Explained
The National Cancer Institute estimates that between 5% and 8% of cancer patients participate in clinical trials. Why is the number so low? Part of the problem is that many patients believe that all clinical trials include a placebo (an inactive treatment with no known therapeutic value) and treat participants like 'guinea pigs' -- neither of which is true. To help clear up the confusion, this Health Alert explains clinical trial terminology, including randomization, placebo, and blinding More...

Preparing For Your Colonoscopy
Many people think the worst part of a colonoscopy is the preparation -- clearing your entire large intestine of fecal matter. Your doctor will give you detailed instructions about the cleansing process, which can take two days or more. Now a study reported in The Archives of Internal Medicine suggests that some bowel cleaning preparations can cause kidney damage in some adults. More...

When Should You Have Your First Colonoscopy?
Colonoscopy is considered the gold standard for finding and removing -- and possibly preventing -- colorectal cancer. It can detect up to 95% of colon cancers and can be used to remove precancerous polyps before they develop into cancer. So it’s important to know when you should begin colonoscopy screening: age 40 or 50? More...

FAP Families at Risk for Colorectal Cancer
It is estimated that about 15% of colorectal cancers run in families. For that reason, it's important to know the health history of your immediate family and to tell your children. A family history of colorectal cancer puts you at higher risk for developing the disease, which means you should have screenings more often than the average person. More...

When the Diagnosis Is Colorectal Cancer
The best way to “treat” colorectal cancer is to prevent it, through regular colonoscopy screenings during which any suspicious polyps can be removed. However, if your doctor does find evidence of colorectal cancer, your treatment options include surgery, chemotherapy, and radiation. In this Health Alert, Johns Hopkins gastroenterologist Sergey V. Kantsevoy, M.D. explains what you should expect if you are diagnosed with colorectal cancer. More...

Eating To Lower Your Cancer Risk
Can diet prevent colorectal cancer from coming back? A number of researchers are zeroing in on certain foods and nutrients that may play an important role in preventing the recurrence of adenomas (polyps that have a high likelihood of becoming cancerous). Here's the latest thinking from Johns Hopkins cancer experts. More...

For Colonoscopy, Location Matters
Not all colonoscopies are equal, a new study finds. Colorectal cancer is more likely to be missed if the colonoscopy is performed in a doctor's office rather than in a hospital or clinic.
Canadian investigators analyzed data from more than 12,000 people with colorectal cancer who had reportedly normal colonoscopies no more than three years before their diagnosis. The investigators found that 3% of the people had a new or missed cancer, some within six… More...

The Size of a Pea and a Lot More Dangerous
Colorectal polyps are small, noncancerous (benign) clumps of cells that grow in the rectum and colon. Over the course of 10–15 years, some of these polyps -- usually the ones that are larger than a pea -- can become cancerous. Fortunately, regular screening for colorectal cancer helps to identify and remove polyps, often before they progress to cancer. … More...

Can Diet Prevent Colon Cancer From Coming Back?
An unhealthy diet has long been associated with an increased risk of developing colon cancer, at times without much evidence other than common sense. Now a growing body of research is backing up these claims with studies showing that people who eat 'good' foods may indeed be able to reduce their risk of developing colon cancer. … More...

Don't assume a normal annual test for fecal occult blood (FOBT) means you can postpone your colonoscopy. According to Frank Herlong, M.D., Associate Professor of Medicine, Gastroenterology Division at Johns Hopkins and Health After 50 Board Member, FOBTs are no longer relied upon for colon cancer screening -- though some doctors may use them to test for gastrointestinal bleeding from causes other than cancer. … More...

Introducing the Aer-O-Scope
Patients who plan to undergo colonoscopy should be on the lookout for the Aer-O-Scope, a new self-propelled colonoscope – still under development.
Colonoscopy, long the gold-standard for colorectal cancer screening, requires specialized training and sedation and can have complications, such as colon perforation. A newly developed instrument could be used with minimal training, without sedation, and perhaps with fewer complications, according to its developers. … More...

Aggressive Treatment Pays Off
For patients with advanced, metastatic colorectal cancer that has spread to the liver, surgery offers hope, according to a study in the Annals of Surgical Oncology.
The treatments for advanced cancer are much the same as for newly diagnosed cancer. However, they are more aggressive. They include: Surgery to remove cancer where it has returned or metastasized. This could be localized or could involve extensive surgery for metastases in the liver or other organs. … More...

Questionnaires Help Predict Inherited Colon Cancer Risk
After age 80, heredity is a major risk factor for colorectal cancer. Now scientists have a new tool to help them identify people at risk for genetically linked colon or endometrial cancer.
It's not known exactly why colorectal cancer begins. Some people carry genes that make them unusually susceptible to certain cancers, and some people have genes that are specific for colorectal cancer. In fact, because colon cancer is relatively easy to identify in the precancerous… More...

The Link Between Fiber and Colon Cancer
A fiber-rich diet has many benefits – but does it protect against colon cancer?
The idea that fiber protects against colon cancer was first proposed many years ago when researchers found that Africans who ate high fiber diets had a low incidence of colon cancer. Since then dozens of studies have supported the protective role of fiber. There are plenty of reasons fiber might lower colon cancer risk: Fiber increases fecal bulk and may dilute… More...
