Thanks to effective therapies, more and more people are now able to live with or after cancer in the long term. Consequently, the number of patients affected by the long-term effects of their treatment is also increasing. Secondary leukemias are particularly serious. These can develop when cellular stress caused by chemotherapy or radiotherapy triggers DNA breaks in specific regions of the genome. If these breaks are incorrectly repaired by the body's own repair mechanisms, detrimental rearrangements can occur that promote the development of leukemia. https://phys.org/news/2026-06-peptide-blocks-dna-treatment-leukemia.html Molecular & Computational biology Mon, 08 Jun 2026 19:10:01 EDT news700157281 Carboranes are molecules composed of carbon, boron and hydrogen atoms that are proving to have applications of great interest in chemistry, materials science and biomedicine. They are being used, for example, in the fight against cancer through boron neutron capture therapy (BNCT), an experimental form of radiotherapy against malignant tumors that is highly selective at the cellular level. These compounds, which are highly stable at high temperatures and under radiation, possess unique electronic properties and can interact with various biochemical molecules. However, chemically modifying them to expand their potential properties and applications remains a challenge. https://phys.org/news/2026-05-metal-free-method-carborane-cancer.html Biochemistry Tue, 26 May 2026 12:20:07 EDT news699012058 In a study published in Nature Nanotechnology, researchers discovered that cuproptosis may serve as a new target for radiosensitization in re-irradiation. https://phys.org/news/2024-09-copper-based-nanocapsules-shown-radiotherapy.html Bio & Medicine Fri, 20 Sep 2024 11:17:22 EDT news646049838 A team of scientists led by Dr. Kei-ichi Takata from the Center for Genomic Integrity (CGI) within the Institute for Basic Science (IBS), has discovered a new type of DNA repair mechanism that cancer cells use to recover from next-generation cancer radiation therapy. https://phys.org/news/2023-03-cancer-cells-dna-next-generation-radiotherapy.html Cell & Microbiology Thu, 16 Mar 2023 14:09:07 EDT news598194543 Decisions on cancer treatment could become better tailored to individual patients with the adoption of a new imaging method being developed by University of Michigan researchers that maps the chemical makeup of a patient's tumor. https://phys.org/news/2023-03-chemical-imaging-efficacy-therapy-individual.html Bio & Medicine Wed, 01 Mar 2023 11:04:03 EST news596891041 Researchers have shown that a protein called fascin acts in the control center of cancer cells and influences their ability to repair themselves, grow and move, according to a study published today in eLife. https://phys.org/news/2022-08-scientists-reveal-key-cancer-halt.html Cell & Microbiology Tue, 30 Aug 2022 10:19:53 EDT news581073588 Scientists have discovered how naturally occurring but unstable molecules, known as free radicals, can control the fundamental process of cell division, which, when it goes wrong, can lead to uncontrolled cell growth and cancer. https://phys.org/news/2022-07-reveals-free-radicals-cell-division.html Cell & Microbiology Wed, 27 Jul 2022 09:47:13 EDT news578134026 Researchers at Lawrence Livermore National Laboratory (LLNL) have shown for the first time the potential for linear induction accelerators (LIAs) to deliver effective, targeted doses of "FLASH" radiation to cancer patients. The new technique selectively kills cancer cells with minimal damage to healthy cells. The approach is outlined in a Scientific Reports paper. https://phys.org/news/2021-12-safely-cancer-patients.html General Physics Wed, 01 Dec 2021 15:56:40 EST news557596595 A radiotherapy technique which 'paints' tumors by targeting them precisely, and avoiding healthy tissue, has been devised in research led by the University of Strathclyde. https://phys.org/news/2021-02-high-energy-radiotherapy-tumours-healthy.html General Physics Tue, 23 Feb 2021 10:37:40 EST news533299020 Scientists have reported a new approach to treating lung cancer with inhaled nanoparticles developed at Wake Forest School of Medicine, part of Wake Forest Baptist Health. https://phys.org/news/2019-11-newly-nanoparticles-lung-cancer-animal.html Bio & Medicine Thu, 14 Nov 2019 12:25:34 EST news492956699 Starting with simple carbon nanotubes, a team of researchers from the United Kingdom and Spain has developed a sugar-coated nanocapsule that can deliver large doses of radioactivity to tumors. The researchers envision developing a series of nanoscale delivery devices that can target specific organs in the body for radiation therapy or imaging by tinkering with the sugar coating on the nanocapsule. https://phys.org/news/2010-07-sugar-coated-nanotubes-high-dose-radiotherapy.html Bio & Medicine Fri, 16 Jul 2010 14:35:41 EDT news198509729 An international team of physicists at Los Alamos National Laboratory has succeeded in using intense laser light to accelerate protons to energies never before achieved. Using this technique, scientists can now accelerate particles to extremely high velocities that would otherwise only be possible using large accelerator facilities. Physicists around the world are examining laser particle acceleration and laser produced radiation for potential future uses in cancer treatment. https://phys.org/news/2009-11-trident-laser-protons-energies.html General Physics Mon, 02 Nov 2009 09:09:30 EST news176375335 (PhysOrg.com) -- Current radiation therapy treatment damages a patient's healthy tissue as well as eradicating the tumour it is intended to destroy, making the treatment especially invasive and often causing nasty side effects. https://phys.org/news/2009-05-breakthrough-radiotherapy-cancer-treatment.html General Physics Tue, 19 May 2009 11:21:40 EDT news161950880 Radioactive elements, or radionuclides, are well-established anticancer agents whose main limitation is that they kill healthy cells almost as easily as they do tumors. But because nanoparticles can be targeted to tumors, researchers have seized on the idea of using nanoparticles to deliver radionuclides to tumors, thus sparing healthy tissues from radiation-induced damage. https://phys.org/news/2007-08-nanotubes-enable-approach-cancer-radiotherapy.html Bio & Medicine Wed, 22 Aug 2007 16:26:32 EDT news107018792
