  On the other hand, the average age of death from breast cancer occurring between age years would be age 55 or perhaps slightly older. Therefore, the average life saved through screening women aged will add around 25 years of life by: breast cancer screening was timely for several reasons. First, only a few monographs exist that focus exclusively on breast cancer screening, none of which represent a comprehensive treatment of the subject, and all were pub-lished before [1–4]. Second, the value of breast cancer screening recently had been challenged by a.

  Breast cancer is the single leading cause of death for women ages in the United States. A year-old individual has a 2% chance of being diagnosed with invasive breast cancer . Because breast density decreases with age and older women have a higher incidence of breast cancer, screening mammography has a higher invasive cancer detection rate in older women compared with younger women (age 80–89 years, / [95% CI. –] vs age 50–59 years, / [95% CI. –]) [16–18].Cited by: 3.

Introduction: For womenmammography screening saves lives, but the benefits are less than for older women. The U.S. Preventive Services Breast Cancer Screening for women aged 40-49 Force meta-analysis of Monograph #1 randomized controlled trials found mammography modestly reduced the risk of breast cancer mortality (death) in women [1].

Dickersin trivialises the importance of breast cancer among women aged 40–49 years. For example, she states “76% of new diagnoses of breast cancer are in women aged 50 and older” and so leads the reader to believe that we should concentrate on detecting cancer in these women and not be concerned with the 24% of new diagnoses that occur among women younger than 50 : Daniel B Kopans.

Breast cancer screening in women aged 40 to 49 continues to make headlines. The American Cancer Society estimates that 20 percent of cases of breast cancer occur in women of this age group, with approximat new cases of invasive breast cancer diagnosed in American women aged To review the evidence on the benefits, harms and costs of breast cancer screening for women aged 40 to 49 years in New Zealand.

A review of the two most recently published meta-analyses of breast. The incidence of breast cancer is lower in women aged 40 to 49 years than in women aged 50 to 69 years (about perversus perwomen, respectively), as is the sensitivity (about 75% versus 85% for women aged under and o respectively) and specificity of mammography (about 80% versus 90% for women aged under and over   Miller AB, To T, Baines CJ, Wall C.

Data from the Breast Cancer Surveillance Consortium (BCSC) for regularly screened women that were based on results from a single screening round indicated that false-positive mammography results were common in all age groups but were most common among women aged 40–49 years ( per women per screening round).Cited by: In case of 20% breast cancer prevalence among women referred after screening (as in the US), the risk of breast cancer despite benign large-core needle biopsy result is less than 1%.

Controversies in Breast Cancer Screening for Women Aged Years 31 December and deaths from breast cancer through 30 June.

Breast cancer is a major cause of cancer-related deaths among older women, aged 65 years or older. Screening mammography has been shown to be effective in reducing breast cancer mortality in women aged 50–74 years but not among those aged 75 years or by: In the summary of their report on the Edinburgh study of breast cancer screening, F E Alexander and colleagues (June 5, p ),1 conclude that “the results for younger women suggest benefit from introduction of screening before 50 years of age”.

However, earlier in the summary they note that “no breast-cancer mortality benefit was observed for women whose breast cancers were diagnosed Cited by: 2.

with age, and breast cancer becomes easier to detect on mammograms with age. For example, in the British Columbia screening programme, the cancer detection rate (per women) was estimated to be for women aged 40–49, for women aged 50–59, and for women aged 60– Benefit of Screening Mammography in Women Aged A New Meta-Analysis of Randomized Controlled Trials Article (PDF Available) in JNCI Monographs 22(22) February.

The dilemma for women in their 40s is that randomised trials of breast cancer screening have, on the one hand, found slower and smaller benefits and, on the other, found more frequent adverse effects than in older by: Until date, there is no consensus about the performance of mammography screening among women aged years.

7 In this age group, breast cancer incidence is lower than that of patients aged years, c but the occurrence of dense breasts and fast-growing tumors is higher. 12 Breast cancer in young women remains poorly by: 3.

While breast cancer does occur in very young women, there is general agreement that, because of its low incidence in this population, screening for all women in their 20's or 30's is not warranted. So we are left with the issue of women age 40 to As a woman enters her forties, she is beginning to move from a time when regular population.

My point was that the issue of screening women aged 40–49 is no longer just scientific, it is also political. Van Bekkum states that the best way to decrease the risks associated with a diagnosis of breast cancer is through early detection by : Kay Dickersin.

Clinical Benefit of Screening The results of the meta-analysis of clinical trials from the systematic evidence review commissioned by the USPSTF are summarized inTable a year period, screen women aged 60 to 69 years will result in 21 (95% CI, 11 to 32) fewer breast cancer.

There is evidence accumulating from these trials of a possible benefit of screening in women under the age of 50 years. A number of meta-analyses of these trials have been performed (Smart et al, ).The most recent of these, published inincluded an average follow-up time of years and estimated a significant 18% reduction in mortality from breast cancer among women aged Cited by:   Nationally, up-to-date mammography screening increased from % in to % in Conclusions and Comment.

After mammography was shown to be effective in lowering morbidity and mortality from breast cancer in the early s, it was adopted rapidly for the early detection of breast cancer (3).
