Several groups looking at data from broad genetic studies have noticed differences in cancer risk for different populations according to ethnic make up.

While widely researched, highly sought after and well-funded, vaccines for most cancers aren't easy to implement. Since a vaccine trains the immune system to attack foreign cells, and cancer cells are still human, the level of precision is difficult.

You may never have heard of this type. Cancer of the appendix is usually thought to be a colon cancer, since the useless organ is part of the 5-6 foot long tube that follows the small intestine.  

A recent study examined cancer genetics to determine why resistance to Iressa ( gefitinib ), a drug commonly used in treating non small cell lung cancer.

The structure of the bile duct, buried inside the liver, is a particularly hard area to monitor. For this reason, treatment is extremely difficult as symptoms show up very late.

The discrepancy between breast cancer risk and alcohol consumption has been frequently questioned, given that patients who consumed only red wine in studies on alcohol appeared to have a decreased risk of the disease.

Some types of cancer treatment are on a molecular level, relying on interactions between growth receptor proteins on the cancer cells and drugs that target these specific receptor proteins.

Obesity has long been associated with increased risks of developing cancer. Diets high in sugar and fat have also been thought to be cancer-promoting. But there haven't been any firm links - until now.

It's such a part of our cultural landscape - that brown color that fizzes and tickles your nose and back of your throat when you pop open a bottle of Coke or Pepsi - that it's even become a part of our lexicon. We describe something as "cola-colored."

Ya either love 'em or you hate 'em. You know those cruciferous vegetables that are among the best things for you on and from the earth. Scientists are getting to know more about why broccoli blocks cancer.
