Women’s Health & Mammogram Controversy… Despite the urgings of national health organizations for women to have annual mammograms after age 40, or half a year of uncertainty and controversy about the process still exists. Based on the cumulative evidence, screening mammography has become the standard of care in many countries. However, the procedure has been challenged by two Danish researchers who monitor the clinical trials of screening mammography declared that five of the seven trials, deficiencies, and none showed. it saves lives
A report published in The Lancet in January 2000, was written by Peter Gotzsche and Ole Nielsen from zero Nordic Cochrane in Copenhagen found that most of the seven monitoring invalid in part. because they failed to assign women to screening and not screening. The two studies are not randomized women properly, researchers say suggests that up to mammography. Cancer specialists from around the world overwhelmingly condemns this report. Institute researchers have even distanced himself from reports that indicate that these findings have not been submitted to the Nordic Cochrane Centre usual rigorous review.
After a storm of criticism, the author of the original Danish review them and say it. “Have confirmed and strengthened” concluded their original states that. “Screening mammography isn’t fair, because there is no reliable evidence that it reduces mortality.”.
Many women are wondering whether they should continue to have mammograms yearly After all, for many years, women were told to do a self-exam of their breasts, but recent suggestions that were canceled after the study. large find it completely ineffective in reducing mortality from breast cancer.
However, other experts have challenged the discrepancy report and confirmed that mammography will save lives. American Cancer Society, found no reason to change the recommendation for screening mammographic year for women over 40 years of age, the National Cancer Institute found that screening has reduced markedly in the death rate. of breast cancer The study, published in the New England Journal of Medicine concluded that 28-65 percent of the sharp decline in deaths from breast cancer from 1990 to 2000 because of mammograms, the rest is a result of the drug. new effective in treating breast cancer.
Since the breast has become the most widely used tumor size at the time of detection has dropped with the death rate from breast cancer. In the early 1980s, when only 13 percent of women in the US get mammograms that tumor size at an average check is about three centimeters by the end of 1990, 60 percent of women having regular mammograms and size. average tumor had shrunk to two centimeters, according to the cancer Society and the National center for Health statistics.
This seemingly small difference in tumor size is extremely important in terms of prognosis. On average, the larger a tumor anymore. (Or faster) it has been growing with the relationship between tumor size and metastasis. More aggressive, debilitating treatment must be carried out with large tumors and, despite this, the survival chances of women with large tumors are worse than those of women with small tumors.
Actually , there are always exceptions and some smaller tumors are aggressive and spread early, while some larger tumors are slow growing and remains localized. Currently, it is impossible to distinguish between them by mammography. Even after a biopsy and microscopic examination, it is difficult to predict whether a tumor’s growth.
The claim is made that the decline of the past in the death of breast cancer by almost two per cent a year since 1990 as a result of drugs and better treatment. However, there is evidence that early detection has made a significant contribution to 29 years of follow-up, died of breast cancer in two counties, Sweden, published in 2001 showed a decrease of 63 percent in mortality from breast cancer in. women were offered mammography, and the reduction of mortality in women, although there is no screen. Better treatment is available to all alike.
Currently, all major US medical organizations recommend screening mammography for women older than 40 and that steps to reduce mortality from breast cancer by 20 to 35 percent in women aged 50-59. and at least 14 years of follow-up in women 40-49.
Mammography is a screening tool is not perfect. Sometimes cause false negative results in women under 50, breast cancer is likely to miss 20 to 25 percent of cancers are in women over 50 and, with about 8-10 percent. this is why when a woman or her doctor felt a lump in the breast that does not appear suspicious in screening should be checked by other means, such as a biopsy.
