Detecting evidence of lung cancer in exhaled breath

Sensing technology could provide a breakthrough in non-invasive lung cancer screening

11-Nov-2024 - Exhaled breath contains chemical clues to what’s going on inside the body, including diseases like lung cancer. And devising ways to sense these compounds could help doctors provide early diagnoses — and improve patients’ prospects. In a study in ACS Sensors, researchers report developing ...

Artificial intelligence improves lung cancer diagnosis

New AI-based digital platform enables extremely fast and accurate analysis of tissue sections from lung cancer patients

27-Aug-2024 - A team of researchers from the University of Cologne’s Faculty of Medicine and University Hospital Cologne, led by Dr Yuri Tolkach and Professor Dr Reinhard Büttner, has created a digital pathology platform based on artificial intelligence. The platform uses new algorithms developed by the team ...

Multi-cancer blood test shows real promise in NHS trial

13-Jun-2023 - An NHS trial of a new blood test for more than 50 types of cancer correctly revealed two out of every three cancers in more than 5,000 people who had visited their GP with suspected symptoms, in England or Wales. The test also correctly identified the original site of cancer in 85% of those ...

Where do toxins from tobacco attack DNA?

In the future, this could make it easier than ever to determine the safety of many chemical substances

24-Feb-2023 - It is known that toxins in tobacco smoke can change our DNA – but where exactly in the genome they do this has been a mystery. A new approach developed by researchers at ETH Zurich now brings light into the darkness. In the future, this could make it easier than ever to determine the safety of ...

Discovering New Cancer Treatments in the “Dark Matter” of the Human Genome

New tool determines potential targets

10-Oct-2022 - Researchers of the University of Bern and the Insel Hospital, University Hospital Bern, have developed a screening method to discover new drug targets for cancer treatment in the so-called “Dark Matter” of the genome. They applied their method to non-small cell lung cancer (NSCLC), the greatest ...

Detection of cancer from exhaled breath

Breath gas analysis for medical diagnostics

03-Dec-2020 - The air we exhale contains information that can assist with the diagnosis of disease. Researchers at the Fraunhofer Project Hub for Microelectronic and Optical Systems for Biomedicine MEOS are now developing solutions designed to enable the analysis of breath gas for this purpose. Although their ...

Attacking tumours directly on identification

Therapy and diagnostics of tumours in only one step is possible with the aid of so-called theranostic agents

04-Sep-2020 - The combination of a biomolecule and a metal complex can target, bind, mark and damage cancer cells. A German-Spanish team has manufactured such a theranostic agent that visualises tumour cells by irradiation with visible light, and proved its effectiveness against lung cancer cells. Andres ...

Freeze-frames of enzymes in action have implications for a new cancer treatment concept

05-Jul-2017 - Over millions of years of evolution, cells have developed myriad ways of regulating the processes that enable them to thrive. Especially useful tools have been saved, or "conserved," over the eons, so that today we can find them in a broad spectrum of life forms, from the very primitive to the ...

Tiny nanoparticles offer significant potential in detecting and treating disease

New review of work on exosomes

26-Jun-2017 - Exosomes - tiny biological nanoparticles which transfer information between cells - offer significant potential in detecting and treating disease, the most comprehensive overview so far of research in the field has concluded. Areas which could benefit include cancer treatment and regenerative ...

A key to metastasis

Invasive lung cancer cells display symbiosis

17-May-2017 - When cancer cells split off from a tumor to seed deadly metastases, they are thought to travel as clusters or packs, a phenomenon known as collective invasion. The members of an invasive pack are not all alike, scientists at Winship Cancer Institute of Emory University have learned. Lung cancer ...
