The Mammography Debate, Part I

This article was presented November 22, 2009, by Ralph W. Moss, Ph.D. in issue #418 of his free weekly newsletter. For further information, including subscription to his reports, see his website.

On Monday, November 16, the United States Preventive Services Task Force (USPSTF) revised its previous position and came out against annual screening mammograms. The new recommendations included the following points:

Women age 40-49 do not need to get routine mammograms.
Postmenopausal women need only get mammograms once every two years, instead of every year, as presently recommended.
Women over the age of 74 do not need mammograms at all.
Physicians should stop teaching women to perform breast self-examinations.

These recommendations pertain to the routine screening of the general population and do not apply to the small percentage of women who are known to be at heightened risk of breast cancer. 

When you consider how central mammography (and breast self-examination) have been to the "war on cancer" you realize how drastic a change this would be. The USPSTF is a very influential and prestigious group, made up of independent experts in prevention and primary care, appointed by the federal Department of Health and Human Services. Yet, immediately, the report became a political football. Some Republicans attacked this as the first sign of healthcare rationing while most Democrats have backed away from the findings as if it were overripe Limburger cheese.

HHS Secretary Kathleen Sebelius said that the report (which her office had commissioned) had caused "a great deal of confusion and worry" among American women. "My message to women is simple. Mammograms have always been an important life-saving tool in the fight against breast cancer and they still are today. Keep doing what you have been doing for years – talk to your doctor about your individual history, ask questions, and make the decision that is right for you." 

Another prominent Democratic politician, Debbie Wasserman Schultz (D-FL) went on the attack:

"I am very concerned that these guidelines conflict with many of the well-established recommendations from the American Medical Association, the National Comprehensive Cancer Network, the American Cancer Society, and Susan G. Komen for the Cure. This conflicting information will inevitably lead to confusion among providers and women, resulting in fewer women getting screened for breast cancer," she said in a statement.

So I doubt if these recommendations will be implemented anytime soon. Indeed, I think this controversy throws a light on the much-discussed topic of health-care reform. There appears to be no mass constituency in the US for cool-headed, rational science, when such findings conflict with the fundamental interests of a large portion of the medical establishment. Mammography is now as American as apple pie.

The co-chair of the USPSTF said that the recommendations were aimed at reducing the harm caused by over-screening. But the very notion of "over-screening" gets short shrift from the cancer establishment, especially from the American Cancer Society (ACS). They have built their reputation on finding all "cancers" as early as possible, especially through mammography and BSE. This would be too radical a shift for their members. 

But, as Robert Aronowitz, MD, of the University of Pennsylvania points out in an op-ed in the New York Times, such recommendations are nothing new. They are the same as most thoughtful experts have been making since the 1970s. "You need to screen 1,900 women in their 40s for 10 years in order to prevent one death from breast cancer," said Aronowitz, "and in the process you will have generated more than 1,000 false-positive screens and all the overtreatment they entail." 

The backlash against the report began immediately. According to a statement by Otis Brawley, MD, chief medical officer of the ACS:

"The American Cancer Society continues to recommend annual screening using mammography and clinical breast examination for all women beginning at age 40." He claimed that ACS has examined the same data as the USPSTF, and had also looked at additional data that the panel did not consider. Generously, he said that "sensible people" could differ over their interpretation of the data.

The National Cancer Institute (NCI) valiantly tried to defend the panel's decision. In its Cancer Bulletin, it soberly evaluated the new recommendations and commented:

"When compared with screening from ages 50 to 69, beginning screening every other year at age 40 produced a small additional reduction in mortality but increased the number of false-positive results by more than 50 percent" (Cancer Bulletin 2009).

Unless you have gone through one of these false positive scares you can hardly imagine what it entails. You are called by the doctor's office and told, usually in a very cryptic way, that there is something wrong with your mammogram and you urgently need to come back for further testing-a repeat mammogram, an MRI or a biopsy. This entails more visits to the doctor's office. Because you may need to arrange transportation and childcare, your friends and family members may get involved. The dreaded "C word" gets whispered abroad. Then comes a period of waiting for the results, which may seem endless. Figure on a few days of lost time and wages. The whole business, multiplied millions of times, puts an economic strain on the medical system.

If you are lucky, the needle biopsy proves negative and you are left to heal your emotional and physical wounds. But sometimes the biopsy detects an abnormality. In rare instances this will be breast cancer. Or it may be ductal carcinoma in situ (DCIS), an amorphous category that sounds like cancer but may not be. What is the medical significance of DCIS? Will it surprise you to learn that, after decades of detecting and treating this condition, nobody seems to know? As the new USPSTF report states:

"Studies on overdiagnosis might also include long-term follow-up of women with probable missed cases of DCIS on the basis of microcalcifications that were missed in an earlier mammogram. Such studies could provide the percentage of these women who develop invasive breast cancer over the next 10 or more years" (Nelson 2009).

In other words, nobody knows how many of these DCIS lesions actually progress to invasive cancer. Since nobody really knows what DCIS means, nobody knows how best to treat it. Again, quoting the USPSTF report says:

"Although the standard treatments women receive for ductal carcinoma in situ (DCIS) include surgical approaches as well as radiation and hormonal therapy, considerable debate exists about the optimal treatment strategy for this condition" (Nelson 2009).

According to breastcancer.org, DCIS is not cancer and isn't life-threatening. But DCIS is routinely treated as if it were full-blown cancer, possibly entailing a mastectomy (surgical removal of the breast). Meanwhile, thanks to mammography, DCIS's growth has been astonishing. In 1983, there were 4,900 US cases of DCIS. By 2008, that number had increased to 67,770 (Nelson 2009). The over-treatment of DCIS has also swollen the ranks of "breast cancer survivors" and mightily improved the cure rate from the disease-because doctors are now "curing" a non-cancerous condition that in all likelihood would not have progressed to cancer.

TO BE CONCLUDED, WITH REFERENCES, NEXT WEEK

The RELATIONSHIPS spoke of the Wheel of Wellness

Let's consider another spoke of the Wheel of Wellness – RELATIONSHIPS (forgiving, compassionate, loving my neighbor as myself, at peace with others)

One of the most often repeated expressions in Scripture is this: “Love your neighbor as yourself.” References include Leviticus 19:18, Matthew 19:19 and 22:39, Mark 12:31, Romans 13:0, Galatians 5:14, and James 2:8.

The foundational statement, Lev. 19:19, was included in God's instructions to the Children of Israel through Moses: “Then the LORD spoke to Moses, saying, … 'You shall not take vengeance, nor bear any grudge against the sons of your people, but you shall love your neighbor as yourself; I am the LORD.'” Also included in that teaching were the Ten Commandments, the “Kosher” laws, and other instructions for daily living. God's teachings were for the benefit and welfare (good health, or wellness) of the Chosen People.

When Jesus first quoted the Leviticus passage (Matthew 19:19), he was responding to a young man of property who had asked, “Teacher, what good thing shall I do that I may obtain eternal life?” Along with other instructions, (do not murder, do not commit adultery, do not steal, do not lie, and honor your father and mother), Jesus told him to love his neighbor as himself. It seems to me that if those instructions are beneficial for eternal life, they are also worthwhile for present life. As I see it, eternal life is not a separate life from the present, but rather a continuation – a new chapter following at the end of the one we are writing now.

In the other gospel passages (Matthew 22:39 and Mark 12:31), Jesus was responding to the question of which is the greatest commandment. Jesus' response gave the first as “Love the LORD your God with all your heart, and with all your soul, and with all your mind, (Mark only: and with all your strength).” Then he added as the second greatest, “You shall love your neighbor as yourself.” That fits with our discussion here: last time we called the first spoke of wellness one's relationship with God, and now the second spoke is our relationships with one another.

The simple fact that this expression came from God through Moses and was repeated by Jesus three times, by Paul twice, and by James gives great weight to the concept. The only new twist I'm adding is that physical wellness is not really separable from spiritual wholeness. Just as separation from God can hamper one's wellness, so also estrangement from family or others can have an adverse effect on wellness. Unforgiveness, holding grudges, lack of compassion all can harm wellness. Remember 2 Corinthians 13:11 Finally, brethren, rejoice, be made complete, be comforted, be like-minded, live in peace; and the God of love and peace will be with you.

This, then, is one more spoke in the Wheel of Wellness.

A Miracle of Modern Medicine

As you may have noticed, my primary focus is wellness by treating my body as it was designed to be treated. But occasionally, I learn of ways that physicians have assisted a patient to wellness using such techniques as surgery.

One current such example is found on a National Public Radio report of November 9, 2009. The report begins, "Trigeminal neuralgia is a rare condition that causes pain so intense it used to be known as the suicide disease." In at least one instance, the unbearable pain was relieved by surgically pulling out and away from the nerve a blood vessel that had become trapped in a loop behind the nerve.
