Detecting breast cancer: 3-D screening reduces recall rates

3D mammogram offers better breast cancer detection
The Netcare Femina Radiology hospital took the decision to start using Hologic's new Selenia Dimensions machine, which uses 3D technology known as tomosynthesis, as it increases the chance of detecting breast cancer by 30% and reduces the need for further investigation by 40%.
A recent trial in Oslo, Norway, proved conclusively that 3D mammography finds more cancers than conventional 2D because it gives radiologists the ability to view inside the breast layer by layer, helping to see the fine details more clearly by looking past overlapping tissue. The tomosynthesis is performed with a four-second sweep of the X-ray tube to give 1mm thin images of the breast. A further advantage is that it uses digital technology instead of analogue, which reduces the levels of radiation exposure to patients.
It is the first hospital in Pretoria and the Greater Tshwane to use Hologic's 3D technology to screen women for breast cancer.
"Breast cancer comprises 25% of cancers affecting women, with one in eight being affected by it at some point in their lives. If detected early, there is an excellent chance of recovery," says Dr Herman Fourie. "Realising the role 3D technology could play in early detection of breast cancer and in reducing the need for further investigation, the hospital decided to offer the 3D mammogram to our patients together with a 2D mammogram (a special X-ray to detect lumps in the breast), at no extra cost," he says. An added benefit of the new technology is that less compression is needed and therefore the test may be completed without being painful.
Dr Fourie advises all women to examine their breasts regularly and if they are over 40, to visit their gynaecologist annually who will then advise them whether they need a breast ultrasound, digital breast tomosynthesis and mammography. Symptoms of breast cancer may include swelling in the armpit, any change in the size, shape, texture or temperature of the breast, lumps in the breast or underarm, unusual swellings, discharge etc. Should you have any of these symptoms he recommends you visit your gynaecologist immediately.
"We take breast care seriously and pride ourselves on being at the forefront of new breast care technology," says Netcare Femina general hospital manager, Joey Breedt.
