History of Breast cancer screening in Timeline

Breast cancer screening aims to detect breast cancer in healthy women before symptoms appear, assuming early detection leads to better outcomes. Various screening methods are used, such as clinical and self breast exams, mammography, genetic screening, ultrasound, and MRI.

1988: Launch of the NHS Breast Screening Programme in the UK

In 1988, the UK launched the world's first national breast cancer screening program, the NHS Breast Screening Programme, which achieved national coverage by the mid-1990s.

1998: Medicare Coverage for Mammography Screening

Starting in 1998, Medicare began covering annual screening mammography for women aged 40 and older.

2002: Launch of BreastScreen Singapore

In 2002, Singapore initiated its national breast screening program, BreastScreen Singapore, targeting women aged 50-64 for screening every two years. This program stands out as Asia's only publicly funded national breast cancer screening initiative.

2003: Breast Cancer Screening in Canada

In 2003, Canadian breast cancer screening programs varied in their offerings of clinical breast examinations and mammography screening for different age groups. Approximately 61% of women aged 50-69 reported having a mammogram within the past two years.

2003: Cochrane Review on Breast Self-Examination

In 2003, a Cochrane review found that breast self-examination was not associated with lower death rates and increased harms due to the identification of benign lesions and unnecessary biopsies.

2005: Breast Cancer Screening Coverage in the United States

In 2005, approximately 68% of U.S. women aged 40-64 had undergone a mammogram in the preceding two years, with varying coverage based on insurance status.

2006: Breast Cancer Screening Coverage in England

As of 2006, roughly 76% of women aged 53–64 in England had received at least one breast cancer screening in the previous three years.

2009: United States Preventive Services Task Force Recommendation

In 2009, the United States Preventive Services Task Force recommended that women over 50 should undergo mammography screening every two years.

2012: Nordic Cochrane Collection Review on Mammography Screening

In 2012, the Nordic Cochrane Collection suggested that advancements in diagnosis and treatment might reduce the effectiveness of mammography screening. They concluded that screening might no longer be effective in preventing deaths and raised concerns about misleading information online.

2013: Cochrane Review on Mammography Screening

A 2013 Cochrane review estimated that mammography screening for women aged 50-75 resulted in a relative decrease in breast cancer death risk of 15%. However, the analysis of least biased trials showed no significant difference in mortality between screened and unscreened groups.

2013: Cochrane Collaboration Statement on Mammography Screening

In 2013, the Cochrane Collaboration stated that the highest quality evidence did not show a decrease in cancer-specific or all-cause mortality due to mammography screening. They highlighted a 30% increase in overdiagnosis and overtreatment, raising questions about the balance of benefits and harms.

2016: Disparities in Breast Cancer Screening Uptake in the UK

A 2016 UK study revealed lower breast cancer screening uptake among women with severe mental illness and those from minority ethnic communities, particularly women of South Asian heritage.
