Lung Cancer Scans Can be Unreliable

In his blog, Dr. Mercola wrote:

It’s important to understand that many medical procedures are not an exact science, and this includes CT scans used to measure cancer growth. In the case of CT scans for lung cancer, this new study showed that radiologists reviewing images of the same patient taken just minutes apart found substantial “changes” in the tumors, in some cases noting they had gotten up to 31 percent bigger or 23 percent smaller.

And in about 3 percent of the cases, the “growth” appeared significant enough that disease progression would be diagnosed, which would undoubtedly impact the person’s future course of treatment, not to mention their state of mind.

Variability of Lung Tumor Measurements on Repeat Computed Tomography Scans Taken Within 15 Minutes.

Patients with non-small-cell lung cancer and a target lung lesion ≥ 1 cm consented to undergo two CT scans within a period of minutes. Three experienced radiologists measured the diameter of the target lesion on the two scans in a side-by-side fashion, and differences were compared.

  • Apparent changes in tumor diameter exceeding 1 to 2 mm are common on immediate reimaging. Increases and decreases less than 10% can be a result of the inherent variability of reimaging.
  • Caution should be exercised in interpreting the significance of small changes in lesion size in the care of individual patients and in the interpretation of clinical trial results.

Here it goes again … How Effective Is Chemotherapy?

How Effective Is Chemotherapy?

Chemotherapy has a FAILURE RATE of ninety-seven percent (97%), or a cure rate of a mere three percent (3%). 

For many years, both Dr. Garcia, M.D. and I have been professing that chemotherapy doesn’t work. We have told our clients that the “success rate” was somewhere around 3%. Most people just find this hard to believe. “You mean oncologists almost always fail to heal their cancer patients?… Nawwww.” We’ve heard this skepticism over and over again. “I know several people who have recovered from their cancers using chemotherapy.” We have heard these comments repeatedly.

Well, finally, Dr. Garcia and his staff have isolated some statistics that back up our statements about the success rate of chemo. I want you to read three articles — or at least parts of them. This exercise, we hope, will finally give you the facts about this subject, not just opinions.

The first article is by Dr. Garcia. He wrote it for his cancer patients at his Utopia Wellness Clinic in Clearwater, Florida. The second article was published in Scientific American in 1985. It talks about the 3% success rate of chemotherapy.

The last article is the most interesting, at least to me. It summarizes the result of a study completed in 2004 by three Australian researchers. They looked at about 73,000 cancer cases in Australia and 155,000 cancer cases in the U.S. from 1990 to 2004. Their overall findings were that chemotherapy improved the 5-year cancer survival rate by an average of 2%. The exact average percentages were 2.1% in the U.S. cases and 2.3% in the Australian cases.

The actual percentages are much lower for common cancers. This is because a couple of rare cancers have a much higher rate. Hodgkin’s Disease has a 40.3% improvement rate; testicular cancer (that of the Lance Armstrong “poster boy” for chemo) has a 37.7% improvement rate. These two, even though rare, raise the average. For the most common cancers, the rates were: breast cancer 1.4%; prostate cancer 0.0%; lung cancer 2.0%; and colon cancer 1.0%.

The study was published in the Journal of Clinical Oncology in 2004 (16:549-560). It is available to all oncologists who want to do some serious study. If I had a 98% failure rate in my profession, I’d look for something else to do. They choose to ignore it and motor on with their warnings that “…if you don’t do this chemo, you’ll die.”

Please, for your own benefit and that of your loved ones, take a look at these articles. You’ll find them by this link:
