US Researchers have designed a new type of ultrasound which has been tested and found to be very effective in determining whether lumps in breasts are cancerous or not.//

The procedure is called elasticity imaging and measures the tissues’ elasticity and compression in response to pressure. Generally tumors are found to be harder and less elastic than benign lumps and thus the test can tell a dangerous growth from a harmless one.

“A tumorous lump should distort very little in response to movement,” said Richard Barr, “whereas a benign one is much more malleable.”

“The finding, if confirmed in a larger trial, could reduce the number of unnecessary breast biopsies and reassure women that their tumors are harmless,” he said . Richard Barr is a radiologist at Southwoods X-Ray and Open MRI in Youngstown, Ohio, who lead the study.

Radiologists found that breast lesions that appeared smaller using the elasticity ultrasound were harmless, while lesions that appeared larger using the elasticity ultrasound were characterized as malignant.

The finding was later checked with biopsy.The results showed a sensitivity of 100 percent and a specificity of 99 percent.

"If we can confirm that the lesion ... is benign, then we can eliminate a lot of biopsies," “MRI is a very sensitive technique. It finds everything. The problem is it is not very specific," Barr said.

"Elasticity imaging appears to have very high specificity," Barr said. "The combination of those two may be a very powerful tool in the detection of cancer." Barr proposes to continue this research at many centers involving more than 2,000 patients beginning in January, he added.

This scan does not appear to be different from a routine ultrasound, which is already used by doctors to try and spot lumps. The only alteration is the addition of a piece of software that can translate the data to determine how much the tissue is
