Pros and Cons of Mammography Screening
Mammography screening is a program with regular intervals done for the purpose of detecting early breast cancer cases so as to reduce the mortality rate due to this cancer and also improve the therapeutic options available while noting that it is also accompanied with some side effects. Mammography is currently the only method proved to be capable of solving the above issues. The following paragraphs will discuss on three advantages of Mammography and four of its disadvantages, starting with the advantages.
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 other advantage of mammography screening is the improvement of the probability of early disease treatment through early detection which leads to reduced mastectomies number, reduced chemotherapy, and better results in the case of breast conservation.
Lastly, on advantages, mammography has enabled the installation of futuristic infrastructure that has been set up to improve coordination and cooperation between diagnosis disciplines which experienced a critical analysis where detection without subsequent assessments happened, something that has helped to improve the quality assurance of the diagnostic chain.
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 shortcoming of this program is that there is a risk of a false alarm, where, like all medical tests, mammography screening may sense abnormalities which ask for further assessment and still turn out to be benign, yet only few women are recalled to take the screen again meaning that they may take the false alarm with them as the results.
The last disadvantage is that of over diagnosis where the mammography scan discovers additional cancers that, in some cases, may not have become apparent if there was no screening done, a double tragedy since their discovery do not reduce mortality and this can be acknowledged by the fact that breast cancer is more in people who have gone through screening than those who did not go through it, provided that their age and composition is the same.
