“…BSE was recommended for this high-risk group despite its failure to reduce breast cancer mortality in the context of a randomized controlled trial that evaluated teaching women at low risk to perform the technique, because of its association with a shorter lag time from the appearance of clinical symptoms to the diagnosis of breast cancer, earlier clinical stage, and smaller tumor size. 31,[38][39][40] The COG-LESG recommended yearly CBE beginning at puberty, with twice-yearly exams starting at age 25 years, annual mammography initiated 8 years after the completion of radiation therapy or age 25 years (whichever comes last), and monthly BSE. 41 The current study has several limitations that should be considered when interpreting the results.…”

BACKGROUNDThe current study characterized the self‐reported cancer screening practices of adult survivors of childhood cancer.METHODSA cohort of 9434 long‐term survivors of childhood cancer and a comparison group of 2667 siblings completed a 289‐item survey that included items regarding cancer‐screening practices.RESULTSOverall, 27.3% of female respondents reported performing breast self‐examination (BSE) regularly, 78.2% reported undergoing a Papanicolaou smear within the previous 3 years, 62.4% underwent a clinical breast examination (CBE) within the last year, and 20.9% had gotten a mammogram at least once in their lifetime. Approximately 17.4% of male respondents reported performing regular testicular self‐examination (TSE). Women age ≥ 30 years who had been exposed to chest or mantle radiation therapy were more likely to report undergoing CBE (odds ratio [OR], 1.59; 95% confidence interval [95% CI], 1.32–1.92) and mammography (OR, 1.92; 95% CI, 1.47–2.56). Compared with the sibling comparison group, survivors demonstrated an increased likelihood of performing TSE (OR, 1.52; 95% CI, 1.22–1.85) or BSE (OR, 1.30; 95% CI, 1.10–1.52), of having undergone a CBE within the last year (OR, 1.18; 95% CI, 1.02–1.35), and of ever having undergone a mammogram (OR, 1.82; 95% CI, 1.52–2.17).CONCLUSIONSThe results of the current study demonstrate that the cancer screening practices among survivors of childhood cancer are below optimal levels. Primary care physicians who include childhood cancer survivors among their patients could benefit these individuals by informing them about future cancer risks and recommending appropriate evidence‐based screening.

“…Studies on women newly diagnosed with breast cancer A total of 15 studies were based only on women newly diagnosed with breast cancer (Greenwald et al, 1978;Smith et al, 1980;Feldman et al, 1981;Tamburini et al, 1981;Foster and Costanza, 1984;Owen et al, 1985;Smith and Burns, 1985;Ogawa et al, 1987;Huguley et al, 1988;Kuroishi et al, 1992;Le Geyte et al, 1992;Kurebayashi et al, 1994;Auvinen et al, 1996;McPherson et al, 1997;Koibuchi et al, 1998) and they were divided into four groups based on two different measures of outcome and two different measures of exposure.…”

Breast self-examination and death from breast cancer: a meta-analysis

2003

View full text Add to dashboard Cite

Breast self-examination (BSE) is widely recommended for breast cancer prevention. Following recent controversy over the efficacy of mammography, it may be seen as an alternative. We present a meta-analysis of the effect of regular BSE on breast cancer mortality. From a search of the medical literature, 20 observational studies and three clinical trials were identified that reported on breast cancer death rates or rates of advanced breast cancer (a marker of death) according to BSE practice. A lower risk of mortality or advanced breast cancer was only found in studies of women with breast cancer who reported practising BSE before diagnosis (mortality: pooled relative risk 0.64, 95% CI 0.56 -0.73; advanced cancer, pooled relative risk 0.60, 95% CI 0.46 -0.80). The results are probably due to bias and confounding. There was no difference in death rate in studies on women who detected their cancer during an examination (pooled relative risk 0.90, 95% CI 0.72 -1.12). None of the trials of BSE training (in which most women reported practising it regularly) showed lower mortality in the BSE group (pooled relative risk 1.01, 95% CI 0.92 -1.12). They did show that BSE is associated with considerably more women seeking medical advice and having biopsies. Regular BSE is not an effective method of reducing breast cancer mortality. British Journal of Cancer (2003) For many years, women have been taught methods of breast selfexamination (BSE) and it is recommended that they practise this regularly (Boyle et al, 1995; Shapiro et al, 1998), usually every month. There is a belief that among women who practise BSE, those who develop breast cancer are more likely to find it at an earlier stage and this is expected to lead to earlier treatment and hence decrease their risk of dying from the disease. Breast selfexamination is appealing as a routine screening method because the examination has no financial cost (apart from the initial instruction sessions) and can be conducted in private. Most studies on the effectiveness of BSE have been observational. They suggest that women who practise BSE are more likely to find their breast tumour themselves, that the tumour tends to be smaller and that these women have an increased survival (Hackshaw, 1996; International Agency for Research on Cancer (IARC), 2002). However, survival time as an outcome measure can be misleading because of lead-time bias, in which BSE only identifies cancers at an earlier stage but has no effect on prognosis. Using mortality rates instead of survival time can overcome much of this bias.Recently, the International Agency for Research on Cancer (2002) published a review on breast-cancer screening that reported the individual results from observational studies of BSE in relation to survival and stage of cancer, and those from randomised trials and cohort studies in relation to mortality. We here, however, present a meta-analysis of BSE and breast-cancer mortality by reviewing the published evidence from both observational studies and randomised trials, including t...

“…Insufficient data exist on methods of breast cancer detection. 1,[5][6][7][8][9][10][11][12][13] Most publications describe local or state populations and may not be representative of the United States as a whole. One publication on a national U.S. database describes only mammographic detection, without information on patient-detected and clinically detected breast cancers.…”

Purpose: The method by which breast cancer is detected becomes a factor for long-term survival and should be considered in treatment plans. This report describes patient characteristics and time trends for various methods of breast cancer detection in the United States. Methods: The 2003 National Health Interview Survey (NHIS), a nationally representative self-report health survey, included 361 women survivors diagnosed with breast cancer between 1980 and 2003. Responses to the question, How was your breast cancer found? were categorized as accident, self-examination, physician during routine breast examination, mammogram, and other. We examined responses by income, race, age, and year of diagnosis. Results: Most women survivors (57%) reported a detection method other than mammographic examination. Women often detected breast cancers themselves, either by self-examination (25%) or by accident (18%). Conclusions: Despite increased use of screening mammography, a large percentage of breast cancers are detected by the patients themselves. Patient-noted breast abnormalities should be carefully evaluated.
