How effective are ultrasounds at detecting breast cancer?
It is known that ultrasound is effective for the detection of small, invasive, node-negative cancers in dense breast tissue, where the sensitivity of mammography drops from 85% to 47.8% to 64.4%.
How often is breast cancer missed on ultrasound?
Conclusions. Although mammography is the standard of reference for the detection of early breast cancer, as many as 30% of breast cancers may be missed. To reduce the possibility of missing a cancer, the radiologist should take the following steps when interpreting mammographic findings: 1.

Does IBC show up on ultrasound?
If a physician suspects IBC, it can be detected with a few different imaging tools, such as ultrasounds or MRI mammograms. The problem with these tests is that they are not completely reliable in detecting IBC; a mammogram alone, for example, only has about a 68% detection rate of IBC.
Can a radiologist diagnose breast cancer from an ultrasound?
Breast ultrasound: Cancers often appear as dark (rather than white) spots on an ultrasound. This can make it easier for radiologists to find small cancers. This is especially true when detecting tumors within dense breast tissue.
Can an ultrasound miss a Mass?
An ultrasound can miss small tumours: “It takes millions of cells to make a tumor big enough to show up on an imaging test.”
