Guest guest Posted May 7, 2008 Report Share Posted May 7, 2008 Cancer Treatment Is An Abject Failure (Actually Worse Than The Disease) http://www.knowledgeofhealth.com/ If you were playing sleuth and tracking recent developments in the world of cancer care, you would get a certain picture in your mind that cancer treatment is a dismal failure and even hastens the demise of patients. Here are recent reports, posted by date at www.thecancerbook.com Friday, October 12, 2007 Chemotherapy of no benefit for younger estrogen-receptor positive breast cancer patients A young woman is told she has breast cancer. She undergoes lumpectomy and possibly radiation treatment, and then must endure chemotherapy. Her hair falls out. She must be given antibiotics to prevent infections caused by damage to the immune system. Then the worst of insults --- She reads the newspaper and finds out chemotherapy was of no benefit. According to a recent study, chemotherapy for breast cancer patients under age 40 is of no value and should be abandoned. About two- thirds of breast cancers are hormone receptor-positive. Tumor cells have receptors or docking ports for estrogen on their surface. Reference: Breast Cancer Research 9:R70, 2007. Wednesday, October 10, 2007 PSA velocity being questioned When the PSA (prostate specific antigen) test was dismissed from many scientific quarters, urologists began coaching their patients to examine the rate at which the PSA number accelerated. Patients bought into this idea and began to opt for treatment. Now researchers say the practice of monitoring the velocity of PSA increase is not necessarily valuable as a screening tool and that patients shouldn't elect to undergo biopsies based on this measure alone.As widespread as this practice is, No studies to date have addressed the costs and benefits of using PSA velocity for prostate cancer screening. An increase in PSA among men with very low PSA number to begin with may be meaningless. Source: Etzioni RD, et al. Is Prostate-Specific Antigen Velocity Useful in Early Detection of Prostate Cancer " A Critical Appraisal of the Evidence. Journal National Cancer Institute 2007; 99:1510-1515. Thursday, October 4, 2007 Pathology Lab Mistake Misleads Patient Who Underwent Double Breast Removal Darrie Eason, a 35-year-old single mother from Long Island, N.Y., underwent a double mastectomy after she was told she had breast cancer. But after the surgery, she learned the unthinkable -- she never had cancer at all. " I remember the words, 'You don't have breast cancer, you never did,' " Eason said today on ABC NEWS " Good Morning America. " Lesson: never rely on one biopsy report. Monday, October 1, 2007 Androgen deprivation therapy for prostate cancer encourages spread of tumor cells (metastasis) Researchers at Johns Hopkins University in Baltimore report that a commonly used treatment for advanced prostate cancer may actually encourage cancer cells to produce a protein that makes them more likely to spread throughout the body. Androgen deprivation. using drugs like Lupron, Zoladex or Casodex, reduces testosterone. Source: Cancer Research, October 1, 2007 Androgen deprivation therapy may also increase the risk of death from heart disease in patients over age 65. Monday, September 24, 2007 Cancer treatments actually increase the number of cancer cells After 30 years of failed cancer treatment, experts are finally conceding modern treatment of cancer has its downsides. Experiments conducted at the Uniformed Services University of Health Sciences in Maryland show that treatments like chemo and radiation do shrink the size of tumors, but they end up triggering a small population of cancer stem cells that drive the disease and promotes the spread (metastasis) of cancer. Source: Science Daily Sept. 22, 2007. Sunday, September 16, 2007 F DA approves drug that allegedly prevents breast cancer, but it promotes blood clots that cause cancer to spread A drug that raises the risk of blood clots that then facilitates the spread of cancer is the second drug approved by the Food & Drug Administration to prevent breast cancer. The drug, Evista (Raloxifene), also used to treat osteoporosis, was found to increase the relative risk of dying from a stroke by 49 percent in a study published last year. Nonetheless, the FDA approved Evista as an alternative to tamixofen. But many women refuse to take tamoxifen because of its side effects. The FDA press release says evidence from three studies show that Evista reduces the risk of invasive breast cancer by 44 to 71 percent, while a fourth larger study showed no advantage over tamoxifen. Why was the data from the largest study separated from the other three reports? (Obvious, all totaled it would have shown no advantage at all). Since 1998 it has been quoted that Raloxifene (Evista) reduces the incidence of breast cancer by a reported 76%. But that figure is specious. The Canada Drug Guide Project explains Raloxifene this way: It is claimed that Raloxifene (Evista) reduces incidence of breast cancer by 76% with only a 1% risk of side effects. What it didn't make clear is the fact that the patients who took the drug in the study went from having a 1% absolute risk of having breast cancer down to a 0.24% absolute risk of having breast cancer over three years (hence, the " 76% " reduction). If measured in relative terms, many of the side effects increased much more than 76%--in fact some risks, such as those for blood clots, increased, relatively speaking, by 300%. Tuesday, August 28, 2007 More frequent screening for prostate cancer finds more tumors, but fails to reduce incidence of aggressive life-threatening tumors Most men who live into their 70s and 80s and beyond will die with, but not of, prostate cancer. But some men do develop a fast-spreading type of prostate cancer that has a high mortality rate. The idea is for men to undergo bi-annual checkups to monitor for prostate cancer in hopes this will find the aggressive prostate cancer that is life- threatening. But a just-released study, published in the Journal of the National Cancer Institute, shows that men who underwent bi-annual PSA testing had about the same risk for aggressive tumors as men who were not screened as frequently. " Although many of us believe that early detection is saving lives, definitive evidence is lacking, " Dr. David Crawford of the University of Colorado Health Sciences Center wrote in an editorial accompanying the study. This makes much of what modern medicine does to monitor prostate cancer nothing more than a " Chinese fire drill. " Friday, August 24, 2007 New Zealanders Wake Up To Reality: There Is No Cure For Cancer In recent months two articles in the New York Times underscore the state of chaos in cancer treatment in America. Now New Zealand health officials concede their " cancer battle plan " is " uncoordinated and ad hoc. " An article in the August 24, 2007 Dominion Post asks: " What is the point of detecting cancer if we don't have equipment and medicines to treat it? " Despite a government action plan, " very little has, in reality, been achieved, " said a documentary report. The report cited patient frustration with a " a truncated, unproven course of Herceptin while the patient must desperately raise funds to personally fund the extended course. " Herceptin is an expensive anti-cancer drug that extends the life of breast cancer patient by a few months at best. Its widespread use would bankrupt most health plans. A Cancer Society official said it was " intolerable " that nine years after the need was identified, cancer patients in the Wellington region were still waiting for a third radiation machine. The $5 million linear accelerator, which fires a gamma radiation beam to destroy tumors, cannot be installed till the ministry decides who will pay an estimated shortfall of $500,000 in treatment funding. While linear accelerators treat cancer, there is little evidence even one cancer has been cured by such treatment. The New Zealand Cancer Society is demanding more treatment, even if it is ineffective. Thursday, August 23, 2007 Does Sun Phobia Promote Cancer? After a young woman developed melanoma skin cancer in Australia following frequent visits to a sun tanning parlor, health officials there have banned use of these UV-ray treatments for children under the age of 16. But will this practice really reduce the rate of skin cancer, and if it does, will it spawn other forms of cancer because of a lack of vitamin D? Simultaneously, researchers report that 10-15 minutes of sun exposure will prevent hundreds of thousands of cases of breast and colon cancer annually. Cedric F. Garland, cancer prevention specialist at the Moores Cancer Center at the University of California, San Diego estimates 250,000 cases of colorectal cancer and 350,000 cases of breast cancer could be prevented worldwide by increasing intake of vitamin D3, particularly in countries north of the equator. Vitamin D3 is available through diet, supplements and exposure of the skin to sunlight. [Nutrition Reviews August 2007] At the same time the U.S. Food & Drug Administration has issued a bulletin claiming labeling of topical sunscreens is incomplete because the labels don't indicate the amount of UV-A radiation they filter. Sunscreens are labeled for their ability to block UV-B radiation, the type of sun rays that produce vitamin D in the skin. The FDA acknowledges that there is no scientific evidence that using sunscreen prevents skin cancer. To learn why cancer rates soared, beginning with the widespread use of sunscreen lotions in 1971, read the book " You Don't Have To Be Afraid Of Cancer Anymore. " Tuesday, August 14, 2007 Recent ejaculation can elevate PSA and mislead doctors and patients regarding prostate cancer risk Doctors in Greece report the case of a 52-year-old Greek man who had no prostate symptoms and who in an annual routine blood test had an elevated serum total PSA of 6 ng/ml (normal range 0-4.0 ng/ml). His personal and family medical history was unremarkable. There was no history of using drugs, or having symptoms of benign prostate hypertrophy, prostate cancer or prostatitis, and he had no recent diagnostic clinical tests of the genitourinary tract. The patient refused digital rectal examination. An abdominal and prostate ultrasound scan showed no evidence of benign prostate hyperplasia or of prostate cancer. Serum total PSA after ten days was 5.2 ng/ml, but the percent free PSA was 27% (normal > 20%). After a month, serum total PSA value dropped to 1.2 ng/ml. In another blood test after 3 months, serum total PSA value rose to 7 ng/ml with a percent free PSA of 40%. The urologist recommended a prostate biopsy. The patient also refused biopsy. After discussing this situation with the patient, his doctors were informed that he had sexual activity and ejaculation in less than 24 hours before the first and before the last serum PSA measurements (being 6 and 7 ng/ml respectively). Ejaculation might have had an effect on serum PSA levels in our patient. All other values of serum total PSA measurements performed at least 4 days after sexual abstinence were Greek doctors suggest a 48-hour period of abstinence prior to total PSA measurement. –Hellenic Journal Nuclear Medicine 10: 119, August 2007. Friday, August 10, 2007 Chemotherapy, hormone therapy and tamoxifen induce bone loss Women receiving tamoxifen for prevention or treatment of breast cancer will experience accelerated bone loss. This is because the inhibition of estrogen entry into cells results in loss of calcium from bones. Stronger estrogen-blockers called aromatase inhibitors pose an even greater risk, increasing the risk of a bone fracture by another 35- 50% compared to tamoxifen. Males with prostate cancer face similar problems. Hormone treatment (androgen deprivation- Lupron) reduces bone mass by 4-5% per year. –Osteoporosis International August 10, 2007 online. Friday, July 6, 2007 Cancer treatment is potentially fatal Standard chemotherapy (combination of 5-FU and irinotecan drugs) can produce such a rapid killing of cancer cells that it may induce acidosis, a life-threatening condition. Called " tumor lysis syndrome, " this fatal complication is admission that first-line chemotherapy for cancers, like colon cancer, is potentially fatal within 72 hours of the first course of treatment. - [Tumori 90: 514-16, Sept-Oct. 2004] Monday, April 9, 2007 Anti-anemia drug decreases survival? Cancer patients frequently experience anemia as the body tightens its control of iron to prevent tumors from growing and spreading. This control is so tight that iron cannot sufficiently get loose to make new red blood cells in the bone marrow. To enhance the quality of life for cancer patients, a drug that boosts a hormone (erythropoietin) in the kidneys, a hormone that boosts red blood cell count, is often prescribed. But there are troubling studies that indicate this drug reduces survival of cancer patients. The patients feel better but die sooner. Survival was worse among patients with breast cancer and the drug actually seemed to encourage tumor growth in patients with head and neck cancer rather than help prevent it. The question is, are cancer patients told any of this? [Lancet Oncology 8: 285, April 2007] Thursday, April 5, 2007 Modern medicine is hidden factor in breast cancer. A sudden, large decline in the diagnosis of breast cancer has occurred due to the decline in use of hormone replacement therapy by women over age 50. As prescriptions for hormone replacement (estrogen) have declined in the US from 62 million to 18 million per year from 2000 to 2005, the rate of breast cancer has dropped from 135 to 126 per 1000,000 women. This means about 30,000 more American women are free of breast cancer in a short period of time, a period of just 2 years under recent analysis. About 200,000 American women are diagnosed with breast cancer each year. The decline was 11.8% for women age 50-69 years of age. [New England Journal Medicine 356:1670-1674, 2007] This information indicts modern medicine has been one of the leading risk factors for breast cancer as it intuitively prescribed estrogen pills rather than relying upon scientific evidence. Wednesday, April 4, 2007 Lung cancer screening may do more harm than good It's difficult to imagine how cancer screening could lead to harm, but efforts to screen for cancer often lead to unnecessary treatment. When fear dominates in the cancer patient's mind, cancer patients may impulsively opt for treatment that may be of little or no benefit. The recent fan-fare is for CT scans that can detect tumors in the lungs and other organs when tumors are smaller and before they cause symptoms. However, CT scans may not reduce mortality rates. CT scans detect more cancer at an early stage, but that doesn't mean treatment is any more effective and most patients will succumb to cancer on the same calendar day. The earlier detection of lung cancer just adds more days between the date of first diagnosis and the date when the patient passes away. Early detection of lung cancer unfortunately does not reduce the number of patients that go on to develop advanced cancer. Early detection with CT scans does increase the amount of treatment that is performed, by 10 times, and since surgery has its own risks (5% of patients die and another 20-40% experience serious complications), efforts to detect cancer at earlier stages may only provide an imaginary benefit. [Journal American Medical Association 297:953-61, 2007] Tuesday, April 3, 2007 Breast cancer guideline impractical The American Cancer Society has issued a new guideline for high-risk women which recommends annual MRI (magnetic resonance imaging) scans starting at age 30. The guideline only applies to 1.4 million women at high risk of developing breast cancer. MRI helps to detect breast tumors among younger women who have denser breast tissue which may obscure detection of a tumor by mammography. However, younger women are not generally considered at high risk for breast cancer, making this recommendation a contradiction in terms. Most women have no idea they are at high or low risk, which clouds the impact of the recommendation. MRI screening is more sensitive than mammograms, but they also are more likely to find benign lumps that generate more needless anxiety and treatment that is based upon fear and imagined disease rather than confirmed cancer. [CA Cancer Journal Clinicians 57:75-89, 2007; New York Times, April 3, 2007] There may be application for MRI scans among women diagnosed with breast cancer in one breast, since a second tumor in the other breast may sometimes be obscure with mammography. In one study, MRI detected hidden breast cancer in the companion breast in 30 of 969 women who were enrolled in the study (3.1%). [New England Journal Medicine 356:1295-303, 2007] Monday, April 2, 2007 Cervical cancer vaccine fizzles According to the Centers for Disease Control, almost 80% of US women have acquired one or more types of Human Papilloma virus by the age of 50. However, over time most genital infections produce no symptoms and resolve spontaneously, probably due to nutritional factors that influence the immune system. The virus can persist in some women and cancer can develop over the subsequent 20-30 years, again proving that age is a primary factor in cancer. Immunizing 11-12 years olds would cost approximately $30 billion in the first 20 years (4 million children per year times $360 X 20) before the vaccine would save a single life, and even then the vaccine's effects may wear off by then. That's a $30 billion price tag for a type of cancer that represents only 0.7% of the cancer diagnoses and death each year in the US. [Nature Biotechnology 25: 261, 2007] Sunday, April 1, 2007 Abandon chemoprevention for colon cancer The US preventive services task force has warned doctors not to prescribe aspirin or anti-inflammatory drugs to prevent colon cancer. Low-dose aspirin is ineffective and high-dose aspirin does reduce risk but also causes gastrointestinal bleeding and possibly hemorrhagic stroke.
