Every year 2800 Norwegian women are diagnosed with breast cancer. Some 800 of them die. The sooner the cancer is detected, the better the chances of survival.
A new method makes it possible to detect the most aggressive types far earlier than previously. At the same time, women with a ’mild’ type could be notified quickly that they are out of danger and not have to carry their fears for months without reason.
Ingrid Gribbestad’s research group at the MR Centre at The Norwegian University of Science and Technology (NTNU) in Trondheim has been a pioneer in the work of developing the method. The innovation involves looking at the biopsies (breast tissue samples) at molecular level.
”Today, we have to study the cancerous tumours in microscopes and observe the dangerous changes with our bare eyes. We operate on the lower level when it comes to size,” Gribbestad says.
The method involves taking a ’fingerprint’ of the molecules in the tissue sample. The principle is already used for liquids such as oil and wine: Fish oils can be traced back to where the salmon came from, while the content of a wine bottle can be traced to a specific vineyard. However, nobody else in the world has managed to transfer the method to a medical analysis of breast cancer before.
”There is no doubt that we are at the top internationally in this area,” says Gribbestad.Based on a normal fingerprint, detectives can say something about the owner’s looks and criminal record, if the person’s identity is known. In the same way, Gribbestad can say something about the behaviour of a particular cancerous tumour – if she knows the history and the molecules of the tumour in question.
That makes it possible, for instance, to establish whether the cancer in this tissue has spread to lymph nodes elsewhere in the body.
Disease profile adaptation
”Another positive aspect is that this ’fingerprint’ also indicates whether the patient will respond to the medical treatment we initiate,” Gribbestad explains.
That makes it possible to find the patients that should be given chemotherapy even before the operation. In addition, cases where it is safe to remove only the affected tissue instead of the entire breast will be easier to find. More breasts will be spared.
“With this we leave the group treatment for the benefit of individual treatment adapted to each patient’s disease profile,” concludes Ingrid Gribbestad.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
