BREAST SCREENING PROGRAMME

Critical Assessment of NHS Breast Screening Programme



Critical Assessment of NHS Breast Screening Programme

Introduction

The NHS breast screening program (NHSBSP) was introduced in the United Kingdom in 1987 to provide three annual screening mammography for women aged 50-64 years. In a previous study of a screening service for West Midlands, only 50% of women with cancer detected on routine recall (incident) screen were re-screened within three years following the previous screen, you suggesting that the round lengths of more than three years may be common. Screening services is expected to operate a round of three years of selection. Radiologists recently published in the NHSBSP guidelines emphasize that women should be re-invited as close as possible to its three-year anniversary of detection, and set a standard of at least 90% of women to be re-invited within two months of the triennial. A method by which the data needed to assess whether this standard is being achieved was not yet identified. (Nandi 2006 980)

Benefits of Screening

Researchers have criticized various aspects of the report of the NHS and questioned their findings on the benefits of screening mammography. Below is a summary of some of his views.

Saving Lives

It is said that the report of the NHS BSP has not shown that breast cancer screening saves lives because you cannot do this. The report of the NHS is quoted as saying that the "Programme of NHS breast screening is now estimated to save 1,400 lives every year." This is the current revision to say that these figures come from a publication of the NHS BSP has not been reviewed. (Amos 2001 1793)

Mortality Reduction

It is said that the origin of some figures in the report of the NHS BSP is unclear, especially those who suggest that "a regular mammogram from 50 to 69 years reduces breast cancer mortality by 35%." This is the equivalent of around three prevention of 1. 000 women die from breast cancer over 10 years of screening. They say a comprehensive systematic review has suggested that breast cancer mortality was actually reduced by 15 to 16%, equivalent to preventing one in 2,000 women die from breast cancer over 10 years: six times less than estimating the NHS. (Amos 2001 1793)

Critical Analysis

Death Trends

It is said that national mortality statistics are not compatible with the impact of screening on breast cancer mortality is required in the report. They say that after 1989, mortality from breast cancer was reduced by 41% in women 40-49 years of age (who are not invited to the selection) with exactly the same reduction (41%) observed in women aged 50 -64 years old who were invited to the selection from 1988. There was a slightly smaller reduction (38%) observed in women aged 65-69 who were invited to the selection from 2001. They say that the reduction in mortality from breast cancer before the program began screening began, and this reduction was greater in the group too young to be examined. (Armstrong 2007 516)
