Question

Two disadvantages of mammography screening include

1. the granularity of the breast can impact visualizations of cancers
2. mammography will not image all cancers
3. radiation dose from mammography is dangerous
A. 1 and 3
B. 1 and 2
C. 2 and 3

Answer 1

The disadvantages of mammography are that dense breast tissue can make cancer harder to detect and not all cancers may be captured; however, the radiation dose is controlled and not considered highly dangerous.

Step-by-step explanation:

The two major disadvantages of mammography screening that are noted in this question are the difficulty of visualization due to breast tissue granularity and the fact that not all cancers are imaged by mammography. The granularity or density of the breast can impact the contrast in mammograms, making it difficult to detect tumors, especially in younger women with denser breasts, which affects visualization. It is also true that mammography may miss some cancers, particularly in dense breast tissue. However, the radiation dose from a mammogram, while a consideration, is generally not categorized as dangerous and is controlled within safe limits. Instead, advancements like MRI are used to complement mammography and improve detection rates.
