Can technology help reconstruct breast tissue?

London: A technology
that helps design buildings, bridges and aircraft is being
enlisted to reconstruct breast tissue in cancer patients.
Researchers used computer-aided design (CAD) to create a precise
mould of a breast to help aid surgeons in tissue reconstruction
operations.
CAD was used to design and produce patient-specific physical
scaffolds that could be used with tissue engineering -- one of the
most promising areas of medicine, the journal Biofabrication
reports.
Theoretically, patients' own cells could be harnessed and grown
onto the highly specific scaffold and then transferred to the
affected area, according to a statement of the Institute of
Physics, Britain.
It would do away with the need to transfer tissue from other parts
of the body which can cause large scars, huge blood loss and
require five to 10 hours of anaesthesia.
Study co-author Dietmar Hutmacher from the Queensland University
of Technology, Australia, said: "We would take a laser scan of the
healthy breast and use the CAD modelling process to design a
patient-specific scaffold."
The Institute of Physics (IOP) under whose sponsorship the project
was undertaken, is a scientific charity devoted to increasing the
practice, understanding and application of physics.
