Cancer is a complicated disease often described by those who know it well in confusing medical, technical, and scientific terms. There's a way to understand it in simple terms, though. And a recent CBS news story features a great run-down on the disease, its causes, how it grows, and more.

Think about this:

• Cancer refers to any one of a large number of diseases characterized by the uncontrollable growth of abnormal cells. These cells have the ability to infiltrate and destroy normal tissue and can spread -- metastasize -- throughout the body.

• Cancer is caused by damage in the DNA. DNA is like a set of instructions for cells and tells cells how to grow and divide. Normal cells can develop mutations in their DNA but can repair most of them. If they cannot make a repair, the cells often die. But certain mutated cells don't repair and don't die. They instead grow and become cancerous.

• Normal, healthy cells grow in an orderly, well-controlled way. They live for a set period of time and then die on schedule. Dead cells are replaced by new normal cells. Cancer cells, in contrast, grow in an uncontrolled manner. They don't die. They accumulate. One malignant cell becomes two, two become four, four become eight, and so on, until a mass of cells -- a tumor -- is created. Tumors remain small until they're able to attract their own blood supply, which allows them to obtain the oxygen and nutrients they need to grow larger.

• Not all cancers form tumors. Leukemia, for example, is a cancer of the blood, bone marrow, lymphatic system, and spleen.
  
  
• Cancer can take decades to develop. By the time a cancerous mass is detected, it's likely that 100 million to one billion cancer cells are present, and the original cancer may have been dividing for five years or more.

• Lung cancer is the top cancer killer among men and women and will kill 160,390 people in 2007.

Twenty years from now, no one will die of cancer and heart disease, according to an expert in Perth, who believes advances in genetic technology will one day leave death by cancer in the dust.

Professor John Shine, director of the Garvan Institute for Medical Research in Sydney, says people will still get cancer -- they just won't die from it. He shared last week at a genetics conference in Perth, "I think there's no doubt death from cancer will be confined to the annals of history, And I think a very similar thing will apply to heart disease."

Despite reservations from some about genetic technology, Shine believes the desire to combat cancer -- once and for all -- will prevail over political opinion. And so that leaves only technical obstacles in the way. It's just a matter of time before these scientific hurdles are no longer issues.

Shine, known as the father of cloning, pioneered gene research in the 1970s when he identified the genes for insulin and the human growth hormone.

Writer Richard Morris of www.breadandmoney.com coins the word nutritainment in a recent article about foods that are hyped to magically make us healthy -- foods that can cancel out cancer and wipe out heart disease. Nutritainment is nutritional news delivered in entertainment-like fashion, designed to urge consumers to buy into the latest, greatest super foods. Yet making small changes in diet -- what most consumers will do -- to incorporate these so-called powerful products is unlikely to do much good, Morris says. And he offers some thoughts on why the media continues to force this news down our throats and why we continue falling for their tactics.

Morris says human nature and marketplace economics motivate those engaged in nutritional sciences to strive for media attention and exposure. As a result, bits and pieces of nutritional studies make their way to medical journals and then land in media's lap through press releases. Some will even ghostwrite nutrition articles to promote products. These articles end up in the hands of the media and spread like wildfire to the public, in as-is format. Consumers may be left with the notion that these bits and pieces are important, relevant, non-biased research -- when this is not the case.

Morris says knowledgeable health experts who have the time to accurately report on important nutrition news are scarce. And when they do have time to share words of wisdom that really do matter, the packaging of the news is often technical and not so sensational. A headline that reads, Pomegranate juice packs power to prevent cancer will bury a scientific -- yet more accurate -- headline. Catchy headlines grab readers, and readers buy products. But headlines can be misleading -- and pomegranate juice alone is not likely to have many health benefits.

There are also issues with advertising and editorial content, according to Morris, who compares overall good nutrition to car maintenance. "Just like changing the air freshener in your car won't prevent a breakdown if the car desperately needs a tune-up, adding one item of magical food to your diet won't protect you from a breakdown either," he says and shares that a complete dietary makeover is what's necessary for good health -- that and stress reduction, physical activity, emotional balance, and life fulfillment. A quick dose of pomegranate juice may not do the trick. But a steady, consistent dose of these items will.

Close to 6,000 U.S. Food and Drug Administration (FDA) scientists were contacted by the Union of Concerned Scientists (UCS) and Public Employees for Environmental Responsibility (PEER) and asked to answer a 38-question survey in an effort to determine the scientific integrity of the agency. Of the scientists contacted, 997 participated in the survey. Following are some key findings of the survey released by UCS:
