As time flies by, more and more progress is made in the fight against cancer. Over the years, new and better screening methods have emerged, cutting-edge technologies have surfaced, successful treatments have saved lives that may have otherwise been lost, and awareness has been raised about all sorts of cancer-related issues. It's amazing really, because in so many areas, we are not making progress.

According to research published in the March/April 2007 issue of WebMD: the Magazine, the per capita consumption of corn sweeteners in 2004 was 78.1 pounds in the United States -- up from 35.3 pounds in 1980. In 2005, the per capita consumption of candy by Americans was 25.7 pounds. We are pumping our bodies full of junk -- our rates of obesity in this country prove it.

When I think about our trend of over-eating and over-indulging, I gain a better appreciation of how far we've come medically. Not only have researchers, scientists, and medical experts made strides in the prevention and treatment of disease, they've done it against the odds. Just think how much more progress we'd make if we all did a little better at living healthy lives. Why not start now?

Daniel Sieberg, science and technology correspondent for CBS News and blogger for Tech Talk recently went searching for online sites offering help and hope for those seeking insight into the world of cancer.

Sieberg went about his search by typing into Google the word cancer. Thrown back at him were more than 250 million results. Overwhelmed by the sheer volume of information and misinformation, Sieberg sifted and sorted through everything that faced him -- and he narrowed down the results to his favorite five.

Sieberg is right on with his picks, and while I personally would have included The Cancer Blog as a source loaded with accurate, reliable, and inspiring information, I still commend Sieberg for so effectively hunting down some very good cancer resources. For what it's worth, I happen to highly recommend them myself.

At the end of November, EarthLink CEO Garry Betty took a medical leave of absence from his job to fight adrenocortical cancer, a serious form of cancer characterized by a tumor that occurs in the adrenal glands above the kidneys. On Tuesday, Betty died at his Atlanta home from complications of the disease. He was 49.

Betty joined the internet service provider EarthLink in 1996 and helped the regional company grow from a provider with 500,000 subscribers into a national powerhouse with more than five million subscribers.

"Garry was instrumental in building EarthLink into the company it is today," EarthLink Chairman Robert M. Kavner said in a recent statement.

EarthLink was just one of Betty's successful ventures. He began his career at IBM Corp. and won the IBM President's Excellence Award in 1982 for his work on the company's personal computer. He also served as CEO of Digital Communications Associates Inc. and at the time became the youngest CEO of a company listed on the New York Stock Exchange.

Betty, who graduated from the Georgia Institute of Technology in 1979 with a degree in chemical engineering, was responsible for 2,200 EarthLink employees. And in support of his team, he attended the company's 2006 Christmas party just three weeks after receiving his diagnosis.

"He put on a tux and came out for a night to make all of us feel better," said Mike Lunsford, interim EarthLink CEO. "And he succeeded."

Betty is survived by his wife, Kathy.

In a discovery that opens up the possibility of stopping the spread of cancer before it has a chance to take hold elsewhere in the body, researchers have developed a means of tracking cancer cells as they spread past the original tumor.

Robarts Research Centre in London, Ontario researchers have announced a new technology that allowed them, for the first time, to follow single breast cancer cells as they migrated from the body to the brain. According to statistics, 22 to 30 per cent of women with breast cancer will suffer from cancer that spreads to the brain.

Interestingly, the new technology also allows them to watch which cancer cells that have spread into the brain develop into a tumor, and which ones remain dormant, or die off. Not all cancer cells become a cancerous tumor.

Of the new technology, Dr. Paula Foster says, "It will give us the ability to test what genes are important, what drugs actually work, how the drugs work. Then you can take that information to patients and hopefully treat this disease a little better."

This is the biggest fear of cancer survivors -- that the cancer will come back, that it will have spread.

Computer-assisted detection (CAD) technology uses computer software to identify and mark areas of concern on mammograms. Radiologists typically review the CAD-marked images after they interpret the original film.

Radiologists can see lesions that CAD sometimes misses so they should not become too dependent on the technology when reading mammograms.

A study was done by the researchers at Group Health to determine the effectiveness of CAD assistance. They found that CAD increased radiologists' ability to determine that the women did not have any cancerous lesions. CAD did not however affect the radiologists' ability to spot cancer when it was present. The physicians performed equally well with and without CAD.

CAD did not mark all visible abnormalities and the doctors could be influenced by the computer's interpretation rather than their own interpretation. Its hard to ignore the technology but the authors of the study recommend training radiologists on characteristics that CAD may miss.

CAD assistance can help radiologists but should not replace their own judgment in reading mammograms.

In the not-too-distant future, dermatologists will be able to diagnose skin cancer without ever cutting the skin.

Right now, doctors cut out all suspicious lesions in order to examine them, to determine if they are cancerous or not. But with the development of a new microscope, cells can be examined right on the body -- without cutting.

Moles matter, reported Matt Lauer on Thursday's TODAY show during an interview with a skin cancer expert. Moles are highly associated with melanoma, the deadliest form of skin cancer. So it is critical that each mole is investigated. With this new high resolution technology -- essentially a video biopsy -- a camera will allow doctors to view cells, zero in on the area of concern, and pinpoint the exact cells that make up a mole. If the cells are similar in shape and size and have equal distribution, the mole is normal. If the individual cells are irregular and have no uniform pattern, the mole is abnormal and probably cancerous.

While cutting for biopsy purposes will one day be a thing of the past, cutting will still be necessary if a mole is characterized by cancerous cells. If it's cancer, it must come out. But the video biopsy can be used to map the border and boundaries and will allow for precise removal of the mole.

This technology is still developing -- but one day, perhaps eight to 10 years from now -- doctors will be able to more consistently detect cancer without removal of skin. For now, they must take a piece of the mole and put it under a microscope.

There are definite warning signs of skin cancer. Any mole that is asymmetrical with irregular borders and varied, dark colors should be reported to a physician. Also, any mole that changes in color, shape, or size and is bigger than a pencil eraser is cause for concern.

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.

Technology has come a long way over the years -- and now the technology behind digital mammography is allowing life-saving screenings for the toughest patients to diagnose with breast cancer.

This is no small technological breakthough. It is a critical component for lowering the breast cancer death rate the American Cancer Society reports has declined 2.3 percent each year between 1990 and 2002. Since breast cancer is a treatable disease if caught early, digital mammography will up the odds of survival for women with this disease.

Digital mammography operates according to a computer-based technique that allows for digital manipulation of a breast X-ray. It exceeds the capability of film mammography -- and is much like the comparison between digital photography versus film photography. Both work. But one works better.

Studies show digital mammograms have a lot to offer. They detect tumors better in young women with dense breast tissue, for example. They allow for ease of storage and retrieval of images. And they can easily become part of a woman's electronic medical record.

There are still benefits of traditional mammography and women are still urged to use this less expensive option. They are also urged to conduct self-breast exams and to report for clinical exams with physicians. It's the whole package that contributes to comprehensive breast health, not just one isolated test. When used in combination with all other screening methods, digital mammography makes for a more accurate overall picture.

I didn't know what was coming when I plopped myself down in the waiting room of an Ear, Nose, and Throat clinic yesterday -- which is a good thing. Had I known what doctors would do to me, I may have run the other way. I may have learned to live with the pain I was experiencing each time I swallowed food. But I waited patiently, aware that doctors would "scope" my esophagus, mildly certain the procedure could be uncomfortable, completely unprepared for the full "scope" experience.

I swallowed a pill on Friday night -- not even a whole pill, just a half of one pill -- and it hurt when it went down my throat. I've had the feeling before, a sensation like the pill got stuck, but the discomfort has always gone away within a few hours. This time, it lasted. It hurt to swallow saliva. It hurt to swallow food. It just hurt. So after three days, I took myself to the clinic -- with the subtle worry that cancer was settling in my esophagus.

I know rationally that every ache and pain I experience is not cancer. But I've had cancer. And so I constantly battle a nagging fear lodged deep in my head that reminds me cancer is always a possibility, that cancer is often a shocking outcome of a routine little test for a simple little health concern.

I do not have cancer. I do not have cancer of the throat, voice box, esophagus, or stomach. That's the good news. The scope revealed -- via a tiny camera that traveled through my body -- nothing but healthy tissue. That makes me happy. The test did not make me happy.

I now know the scope is a long, thin tube that enters the body through one nostril. Ouch. It travels into the throat. Ouch. The patient swallows when it reaches the throat to assist in maneuvering it down further. Ouch. The scope then makes its way past the voice box, though the esophagus, and into the stomach. Ouch. Ouch. Ouch. The travels are all displayed on a monitor, and I actually got a glimpse of these body parts -- during the split second when I was able to control my gagging, loosen my grip on the arms of the exam chair, and open my clinched eyes. So I saw for myself that everything looks healthy -- just before the tube was pulled right back through all these parts, leaving me with a very sore throat.

Now that I am home and have talked with a few people, I hear that some patients are unconscious for this procedure. They are completely unaware of the horrors of the scope. I got a few sprays to numb my nose and throat and drank a thick cocktail of lidocaine -- but I did not get the luxury of unconsciousness. And in the end that is okay. I got to see what was happening. I got to hear the doctor's revelation that nothing major is wrong. I got to witness the wonder of medical technology. I got to prove to myself that I can handle a little discomfort in exchange for a clean bill of health. And I got to learn that I have a bit of acid reflux. And now I have to squash that nagging fear that reminds me of the literature out there suggesting a link between acid reflux and cancer.

Kim Taylor is a 45-year-old single mother who lives in Suwannee County, Florida and is proud to have successfully raised one daughter -- a graduate of the University of Florida. Kim enjoys outdoor activities like camping as well as sewing, crafting, and carpentry projects. She is most at peace spending time with her family, working as a youth volunteer -- and raising awareness for breast cancer. It's a interest she acquired just two years ago, compliments of a personal encounter with the disease that has taught her to let the little things go, to appreciate every sunrise, to make every moment matter.

Research presented at the meeting on Molecular Diagnostics in Cancer Therapeutic Development, organized by the American Association for Cancer Research, says that in the near future the United States will have a new way to detect distant metastasis sooner in breast cancer patients.

The company AdnaGen's diagnostic tool is being evaluated in clinical studies at The University of Texas M.D. Anderson Cancer Center in Houston. The tool can spot one malignant cell in a typical blood sample.

Using the new technology cancer cells can be captured and analyzed to identify several gene products, including potential molecular targets for a specific drug. Treatments for metastatic breast cancer usually will be given based on the features of the primary tumor. The cancer's primary tumor can be estrogen negative but the metastasis can be estrogen positive. Knowing this information can open up more treatment options for those diagnosed with metastatic breast cancer.

AdnaGen, which is marketing its breast cancer assay (as well as assays for colon and prostate cancer) in Europe, is awaiting the results of a clinical trial before applying for FDA approval to make the test available in the United States.

At this time, there are 200 companies engaged in 600 clinical trials that involve 340 immunotherapy drugs -- all under study in an attempt to assist in the treatment of 40 different cancers. The top five targeted cancers are melanoma, breast, lung, prostate, and colorectal.

While antibody studies are the top headline-makers right now, cancer vaccines are following behind. With the recent approval of Gardasil -- the cervical cancer vaccine -- the push for more vaccine options will become strong. Future industry challenges also include discovering strong antigens, effective immunomodulators, and suitable delivery technologies.

Powerful drugs like Avastin, Erbitux, and Rituxan are just the precursors to what might lie ahead for cancer patients as a result of this widespread effort to knock cancer out of the ballpark.

The governments of Canada and the US are both closely involved in the delivery of health care. The main difference between the two is health insurance. In Canada, the federal government is committed to providing funding support. In the US health insurance must be paid for privately or is provided by the person's employer.

There are many uninsured Americans. I was lucky that I had a good insurance plan with my job. After my cancer diagnoses I didn't have to wait very long for appointments and medical procedures.

An article I read states that "American doctors and hospitals are more likely than their Canadian counterparts to purchase new and expensive devices and technologies. An American patient is more likely to be rapidly treated by a specialist with the most up to date equipment. Canadians are more likely to be treated by their GP and cared for over a period of time in the hospital."

One of the most important factors in finding a cure for cancer is to figure out what causes our cells to change and become malignant. A study was done by Edinburgh scientists at the University of Edinburgh Cancer Research Centre.

There is an important protein residing in our cells that inhibits cancer. This protein is called p53. Another protein called MDM2 controls the activity of the p53 protein. The study showed that the ratio between the MDM2 and the p53 protein can become unbalanced. This can cause the P53 protein to not perform as it should.

If the cell protein MDM2 can be stopped from interfering with the protein p53 then that is another way that scientists can come up with new therapies to treat cancer. Let's hope for new non-toxic therapies while we are at it!

"A composer is a guy who goes around forcing his will on unsuspecting air molecules, often with the assistance of unsuspecting musicians." -- Frank Zappa

Frank Zappa -- intelligent and articulate; gifted and prolific as a rock musician and composer; guitarist, singer/songwriter, film director, and satirist -- lost his life to prostate cancer in 1993. During his musical career, he gained a cult-like following of fans by pushing the iconoclastic envelope and by mastering the technology needed to create his complex musical compositions.

One of Frank's sons, Dweezil Zappa, wants to set the record straight about his father. According to Dweezil, "There are so many things that are misunderstood or not recognized about my father's music because they've been filtered by people who work for magazines like Rolling Stone.

For example, Rolling Stone recently printed a poor, artist-rendering of Frank holding a joint.

Frank has always been well-known for being anti-drug yet they would rather continue to perpetuate a false image of him, even after death. It's irresponsible, it's obnoxious and offensive. I think it's time people know what Frank was really about, and they should discover it through his music."

To that end, Dweezil, with his brother Ahmet, are touring Zappa Plays Zappa and introducing a whole new generation to Frank Zappa's music. You can follow the tour at the Zappa Plays Zappa blog.
