Benefits and Shortcomings of Mammography Screening
Mammography screening is a program that allows for early breast cancer detection to reduce mortality and improve therapeutic options through regular intervals at a cost but is also associated with some side effects. As of now, it is the only method that has been proved to meet the above needs. The paragraphs below explain 3 of the pros of mammography screening and 3 of its cons, starting with the advantages. about this website
Mortality reduction is the first advantage and the major goal of mammography screening but requires many years to be effective as death from all types of cancer occur during the advanced stages hence it is hard to assess it. Mortality reduction is currently estimated between 15% to 30% in a study where 70% of the women did not participate in the program and it is estimated to exceed 35% for those participating.
The second advantage brought by the early detection due to mammography screening is the increased probability of early treatment since early detection leads to reduced chemotherapy, low number of mastectomies, and improved results from breast conservation
The last advantage is that there is improved quality assurance of the diagnostic chain where promising infrastructure has been put in place so as to optimize the coordination and cooperation of different sections of diagnostic chain due to the cases of detection without subsequent assessments.
To begin on the shortcomings, the first is that mammography exposes the women to risks of radiation and other risks with the digital mammography techniques offering a dosage of 4mGy per breast, whose effect however decreases with the increase in age, as women beyond 40 years have less chances of dying due to breast cancer.
The second con of the mammography screening is that, like the other medical tests, there is a risk of it giving a false alarm, where the screening may detect abnormalities that require some more intense analysis but turn out to benign even for the second time, making the women who go and never come back for subsequent screens live with a false alarm that they have cancer in their minds. read more now
Lastly, there the risk of over diagnosis whereby some additional cancers detected may not have come to affect the person if the screening was not done and detecting them does not reduce death rates and this can be proved by the fact that a screened population of the same composition and age tend to have more breast cancers than the unscreened population with the same composition and age.
