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 A new study led by researchers at the Institute of Materials Science of Barcelona (ICMAB-CSIC) reveals why a particular boron-rich molecule, called o-FESAN, behaves in an unusually helpful way, remaining intercalated into DNA even though it was thought it should be repelled by it.

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 Chemotherapy is one of the most used treatments against cancer, along with surgery and radiotherapy. In a chemotherapy treatment, one or several drugs are administered to the patient to remove or damage cancer cells. Nevertheless, the treatment has several drawbacks that are hard to overcome, particularly the side effects. In this case, the inherent toxicity of the drugs employed causes a variety of symptoms including weakness, nausea and hair loss. As a result, chemotherapy is far from an ideal approach. https://phys.org/news/2019-09-nanotherapy-delivery-chemotherapeutics-cancer-stem.html Bio & Medicine Tue, 10 Sep 2019 07:01:39 EDT news487317688 Cancer treatment often involves a combination of chemotherapy and radiotherapy. Chemotherapy uses medication to stop cancer cells reproducing, but the medication affects the entire body. Radiotherapy uses radiation to kill the cancer cells, and it is targeted to the tumour site. In a recent study, published in the journal European Physical Journal D, researchers from the Leopold-Franzens-University Innsbruck, in Innsbruck, Austria, studied selected molecules of relevance in this context. They wanted to see how these molecules were individually affected by radiation similar to that used in radiotherapy. https://phys.org/news/2019-08-chemotherapy-drugs-react-differently.html Condensed Matter Wed, 07 Aug 2019 11:07:04 EDT news484394815 A Google project to develop nanoparticles that can detect cancer cells inside the body is a useful contribution but faces important hurdles, experts said on Wednesday. https://phys.org/news/2014-10-experts-cautious-google-nanoparticle.html Bio & Medicine Wed, 29 Oct 2014 14:40:01 EDT news333810752 Scientists from Queen's University Belfast have been involved in a groundbreaking discovery in the area of experimental physics that has implications for understanding how radiotherapy kills cancer cells, among other things. https://phys.org/news/2014-10-attosecond-science-breakthrough.html General Physics Tue, 21 Oct 2014 10:51:46 EDT news333107497 Doctors shrink tumors with radiation therapy, but a badly calibrated beam can cause serious complications. Scientists in NIST's Radiation Physics Division in the Physical Measurement Laboratory (PML) are developing a new set of techniques that could someday take the place of current standards. Their proof-of-concept work demonstrates a potentially better way to calibrate a radiotherapy beam by measuring subtle changes in the temperature of a phantom, or proxy for a person, using ultrasound or optical light. https://phys.org/news/2014-09-calibrating-cancer-radiotherapy.html General Physics Thu, 18 Sep 2014 09:10:01 EDT news330247946 Nearly every second dog develops cancer from the age of ten years onward.

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
