3D Image to view affected Tissue

Microwaves give a new resolution for cancer.Chalmers University developed a new technique to detect  of cancer, through 3D images and destroy the affected tissue  with the help of microwaves by heat, which could play a pioneering role in the fight against this disease. The developers of these techniques, led by Professor of Bio-medical Electromagnetics, Andreas Fhager believe that could save many more lives than it currently does, as this technology is more effective, less invasive and simpler than all the alternatives currently available.

Heat to eliminate the tumor

Microwaves are used to destroy tumors through the heat in a process known as hypothermia. Clinical studies have shown that treatment with conventional radiotherapy and chemotherapy in combination with hypothermia long term can double the capacity to cure certain cancers such as cervical cancer and soft tissue sarcoma. "We are currently developing a hypothermia system that can reach new deep tumors in the head and neck with great precision," says Hana Dobsicek Trefna, Ph.D. in Biomedical Engineering and notes that ‘in this way, higher temperatures can reach the tumor without affecting surrounding tissues’.

Patients classifications by risk groups

The findings also helped the team to accurately classify patients into three risk groups: high, medium and normal. Professor Richard Grundy, Dr. John-Paul Kilday and colleagues found an association between a greater number of copies of a specific region of a chromosome 1q25 called and about 20% of tumors obtained from children who are diagnosed variant of the deadly brain cancer.

Increased probability of survival

At the same time, however, has also substantially increased the chance of surviving cancer thanks largely to advances in the diagnosis and treatment. In the five years after the disease, children survive by 75% in Western Europe and 64% for children in Eastern Europe, with the same increase in the case of adolescents. In the 70's, however, survived cancer 44% of children, and 50% of adolescents.

Childhood cancer has increased the last thirty years

Among adolescents aged 15 to 19 years the average has increased at a rate of 1.5% per year. However, advances in diagnosis and treatment have reduced infant mortality from the disease in the West. Are results from analysis of data provided by 19 European countries, By   Vanessa Marsh. The International Agency for Research on Cancer (IARC) reports, the incidence of childhood cancer and the survival of children with cancer in Europe has increased over the last thirty years, The results of a study conducted by Dr. Eva Steliarova-Foucher, project director at the IARC, and his colleagues have produced clear evidence of that increase. 

Tracking with Chandra

In this study, researchers focused Chandra to a given parcel of the cosmos, for more than six weeks, to the Chandra Deep Field South called (CDFS). This region, located in the so-called constellation Fornication, is the deepest X-ray exposure ever produced.These images showed that young black holes grew in the early stages of the universe, more aggressive than has hitherto been believed, and while growing up that staying galaxies (or their host galaxies). 

Symbiosis between black holes and galaxies

Two critical questions about how black holes are formed the first super massive black holes and how they grew. Although evidence was found that there was a parallel growth of black holes and galaxies at cosmological distances shorter, these new results from Chandra show that the connection between galaxies and black holes began earlier than previously thought, perhaps the origin of both.
