New breast screening uses 3-D technology

New 3-D screening 'more successful' at detecting breast cancer

A NEW TECHNIQUE for detecting breast cancer which uses 3-D technology is more successful at finding signs of the disease, scientists say.

Initial results from a trial in the US found that stereo mammography, which allows doctors to view breast tissue in three dimensions, found that it missed 40% fewer cases of the cancer than the standard approach.

It also resulted in half as many false positives – where doctors thought they had detected an early stage tumour where none existed.

Dr David Getty, a scientist from BBN Technologies, the American company that is developing the new technology, said two-dimensional images often failed to pick up signs of cancer – or misinterpreted healthy tissue as diseased.

‘Standard mammography is one of the most difficult radiographic exams to interpret,’ he said.

The technique is currently being tried in more than 1,000 women who have an increased risk of breast cancer in Atlanta. It has not yet been trialled in the UK.
