WHAT if there was growing evidence that an already-existing drug, taken daily, might dramatically reduce the risk of breast cancer?
Shouldn't that be more newsworthy than fund-raising walkathons done in the quixotic pursuit of a simple cure? More noteworthy than the latest lab test which classifies an environmental chemical as a rodent carcinogen?
U.S. scientists, led by Harvard's Dr. Peter Goss, this week began recruiting women at high risk of breast cancer to participate in a study of what may well be just such a drug.
That "chemical prevention" of cancer has come so far will be a shock to most Americans but it is no surprise to those of us following this fast-paced research involving the use of drugs to both reduce the chances of breast cancer in healthy women and the risk of recurrence in in those previously-treated.
For example, for a decade it has been apparent that Lilly's drug Evista, now approved only to prevent osteoporosis, has the side benefit of reducing breast cancer risk. Because that would be an "off-label use," Lilly isn't allowed to publicize the data on Evista's preventive properties but physicians are generally aware of this side benefit.
The more recent news which triggered the new U.S./Canada study revolves around a group of drugs known as aromatase inhibitors, which dramatically reduce the levels of estrogen in postmenopausal women.
This class of drugs which includes Astra Zeneca's Arimidex and Pfizer's Aromasin has already been shown, as Dr. Goss puts it, to "profoundly" reduce the risk of recurrence in women who have already been diagnosed and treated for breast cancer and to do so with fewer side effects than an earlier drug, Tamoxifen. Arimidex decreases the chance of cancer developing in the other breast by almost 80 percent.

I was making the point that this kind of emotion-based, scientifically ignorant misinformation is harmful, prejudicial and just flat wrong. When we look at the results of studies, we need to be very careful. You can say "current studies show that there may be a link between...and...", or "studies indicate a trend", but you can't say that something is the "number one preventable cause of breast cancer".
And, I am healthy now thanks to the miracles of modern medicine, thank you.
Well, gee, so much for possibly getting to the root of the problem of post-abortive womens' depression. *spit*

Thank you.
Ahhhh, thanks for the insight!

Always a Bitter Pill, Now the Risk of Breast Cancer Makes Oral Contraceptives Even Harder to Swallow
"It may not have rocked the ground like the 1945 detonation of the first atomic bomb . . . but Enovid did more than just provide a technological tour de force. It transformed the very fabric of modern society . . ."
So reported "The Pill At 40", an article in the July-August 2000 "FDA Consumer" magazine, singing the praises of the Pill and celebrating the 40th anniversary of its approval by the Food and Drug Administration. On June 23, 1960, Enovid became the first oral contraceptive approved for sale in the USA, following several years of development and trials on third world women.
The article failed to mention the bitter legacy of the Pill over that same 40 years. Minor side effects abound, such as nausea, irregular bleeding, depression, weight gain, breast tenderness, and diminished libido. Some, however, are life threatening. Blood clots, pulmonary embolism, heart attack, and stroke have claimed the lives of many women taking the Pill since its introduction in 1960. Decreasing the dosages of the hormones in the Pill have lessened but not eliminated these deadly risks.
"Postfertilization Effects of Oral Contraceptives and Their Relationship to Informed Consent" was the first medical journal article to explain the mechanism by which the Pill prevents implantation of a fertilized egg in the womb, its lining (or endometrium) improperly formed under the influence of the Pill's hormones. Published in the February 2000 Archives of Family Medicine, a journal of the American Medical Association, it proved for both the secular world and a divided pro-life movement that the Pill is not only a contraceptive but also a chemical abortifacient. The report concludes:
"The available evidence supports the hypothesis that when ovulation and fertilization occur in women taking OCs, postfertilization effects are operative on occasion to prevent clinically recognized pregnancy. Physicians should understand and respect the beliefs of patients who consider human life to be present and valuable from the moment of fertilization."
While litigation in the USA relative to the Pill has been limited to suits aimed at forcing insurance plans to cover the Pill, in Britain a class action lawsuit has begun addressing another aspect of informed consent. In January 2002, 122 women and/or their families will take three pharmaceutical companies before England's High Court, charging that the Pill has caused blood clots resulting in lifelong illnesses and even death, and that they were never informed of the severe risks. Ten percent of the 122 claims involve a fatality. Unfortunately, these side effects have been known for four decades, and the prospects of success for these victims are uncertain.
However, compelling data has emerged linking the Pill with the rapid increase of breast cancer in the US, with a potential of class action lawsuits that could eclipse even those of the tobacco industry. Evidence has been available for several decades linking oral contraceptives with breast cancer in certain lab animals. According to Chris Kahlenborn, MD, one of the nation's leading researchers on the breast cancer/ Pill connection, the evidence of a link in humans is incontrovertible. His book summarizing his research and findings, BREAST CANCER: Its Link to Abortion and the Birth Control Pill, was published recently by One More Soul (www.OMS.com.) Dr. Kahlenborn has testified before the FDA regarding the issues in his book, and the book's findings are now part of the federal record.
In the book he makes a compelling case for such a link. He began researching the issue after hearing a presentation in 1993 that described an increase in breast cancer risk due to abortion, apparently caused by hormonal changes in the woman's body. He began an exhaustive review of the research to ascertain whether contraceptive hormones in the Pill might have the same effect.
When asked, "What is the bottom-line, after 8 years of exhaustive research and study?" Dr. Kahlenborn replied, "There is a 45% increased risk of developing breast cancer if a woman takes an oral contraceptive prior to her first full term pregnancy. This number is statistically significant to the 99th percentile."
"Informed consent is MIA. Catholic OB/GYN's are doing a grave disservice in handing this out. Today's cigarette story [the tobacco class action lawsuits] could be tomorrow's Pill story. There is no informed consent. The breast cancer and the social effects cause such devastation to families!"
He compares the current state of denial among the American medical establishment to a similar episode that occurred several decades ago. "History is repeating itself. DES was taken in the 40's and 50's to prevent miscarriage. A 35% increased risk of breast cancer was found." At the time DES (diethylstilbestrol) was used, some were concerned of a potential risk of breast cancer, while the American medical establishment denied the possibility. Only after 25 years was it discovered that DES use carried a 35% increased breast cancer risk.
Currently, more than 192,000 U.S. women develop breast cancer and more than 40,000 die from it each year. One in eight women in the US will be diagnosed with breast cancer in their lifetime. Yet 50 years ago, breast cancer was less common. When asked what other factors might account for such a rapid increase in the rates of breast cancer, Dr. Kahlenborn was blunt. "I am not sure of all the factors but two other factors come into play: decreased family size and decreased breast-feeding. Pregnancy and breast-feeding have been known to protect against breast cancer for many years. But the Pill and abortion also are likely responsible for the rising rates of breast cancer in Western countries." Breast cancer is increasing more rapidly in western countries, countries with early Pill use, often in the teen years, usually before first full term pregnancy.
Medical research findings have been contradictory. In 1972 a series of animal research studies showed that an oral contraceptive appeared to cause metastatic breast cancer in rhesus monkeys, which rarely develop breast cancer. In 1989 Anderson et al published a paper that found that women who had never had children who took the Pill had a significantly higher rate of breast cell division than childless mothers who had never taken the Pill. In general, cells that divide more rapidly are more vulnerable to carcinogens and more likely to become cancerous. A study in 1981 found that women who took the Pill for 4 years prior to their first full-term pregnancy (FFTP) had a 125% increased risk of breast cancer before age 32. In 1993, the CASH study showed a 40% increased risk in women taking the Pill before FFTP. Later in England another large study revealed a 44% increased risk. The last large study in 1995 showed a 42% increased risk. A meta-analysis (a statistical analysis of many other research studies) in 1990 found that, overall, the studies up to that time confirmed an increased risk of breast cancer of 72% for women under age 45 who took oral contraceptive pills for 4 or more years before having a full-term pregnancy. Use of these contraceptives for longer periods appears to carry an even higher risk.
However, the Oxford study, the largest meta-analysis to date, concluded that:
"Women who are currently using [the Pill] or have used them in the past 10 years are at a slightly increased risk of having breast cancer diagnosed, although the additional cancers tend to be localized to the breast. There is no evidence of an increase in the risk of having breast cancer diagnosed 10 or more years after cessation of use..."
Dr. Kahlenborn sees severe weaknesses in the Oxford study. He states in his book:
"The main weakness was the failure to report any evidence of what the pooled risk of oral contraceptive use before a FFTP was in women under 45 years old . . . A woman's breast is especially sensitive to carcinogenic influence . . . before [FFTP] because the breast undergoes a maturing process throughout a woman's first pregnancy. By failing to measure the effect . . . before a . . . woman's [FFTP] the Oxford study failed to give data on the one group of women who are most likely to get breast cancer from oral contraceptives." Dr. Kahlenborn commented further, "In addition the Oxford meta-analysis used studies whose data came from as early as the 1960s. This is not precise enough since these studies would not have picked up the Pill's effects on the breast (ie, too short of a latent period).
Currently Dr. Kahlenborn is working on another meta-analysis that he hopes will be published within one year. This analysis attempts to analyze the data of all the studies available from the 1980's and 1990's, in an effort to obtain a more accurate statistical analysis specifically of women taking the Pill for several years prior to their first full-term pregnancy.
The Food and Drug Administration's FDA consumer magazine maintained that Enovid may not have rocked the ground like the 1945 detonation of the first atomic bomb. Dr. Kahlenborn would be inclined to disagree. "Hormonal chemical contraceptives are the equivalent to a nuclear bomb in their devastation to the family." Sickness, cancer and death lies in the wake of this bitter Pill. Can massive product liability suits be far behind?

Dr. Janet Daling is a cancer researcher at the Fred Hutchinson Cancer Research Center and the University of Washington. Dr. Daling is self-described as 'pro-choice'. On 2 November 1994 Dr. Daling and fellow researchers published an article in the Journal of the National Cancer Institute (pp. 1584-1592) concerning induced abortion and breast cancer risk for premenopausal women. Some key findings:
The Journal of the National Medical Association is a publication by black medical professionals concerned with black health problems. In the December 1993 issue JNMA published the results of a Howard University study. Key finding:
Black women of age 50 and above who had at least 1 induced abortion have an increased breast cancer risk of 370%.

Each study above is listed by first author's name, year of publication, and nationality of women studied. On the right-hand side of the figure, the horizontal line with a central circle, given for each study, represents (on a log scale) the 95% confidence interval (CI) for the effect of induced abortion on the entire population studied, with the central circle representing the "point estimate" of "relative risk" (RR). This RR value represents how many times more likely to develop breast cancer, in that particular study, is a woman who had at least one induced abortion, relative to a woman who has not had an induced abortion. For example, in the 1984 French study of Le et al shown above, the point estimate of RR is 1.5, with a 95% CI that spans from 1.0 to 2.2. In other words, the study found that women who had at least one abortion were, on average, 50% more likely to develop breast cancer, and that one can be 95% certain that the increased risk is between 0% and 120%.
Point estimates to the right of the vertical line of unity (RR=1) indicate increased risk; while those to the left indicate decreased risk. If the 95% CI does not cross the line of unity, the results are said to be statistically significant. Narrower 95% CI's denote greater certainty about the RR value, reflecting larger studies with greater statistical power. Thus, the figure illustrates the fact that of the 33 published worldwide studies, 27 show increased risk, 17 of which are statistically significant. The pooled average from all the studies combined, calculated by two different methods, is shown at the bottom. It clearly indicates a significant risk increase averaging 30 to 40%.
The 1981 study of Pike et al. is limited to women with any abortions before first full-term pregnancy, the 1988 study of Ewertz and Duffy and the 1996 study of Wu et al. are limited to women with no children, and the 1957 study of Segi et al. is limited to women with children.
