22/09/2016Deaths from ovarian cancer fell worldwide between 2002 and 2012 and are predicted to continue to decline in the USA, European Union (EU) and, though to a smaller degree, in Japan by 2020, according to new research published in the leading cancer journal Annals of Oncology.
19/09/2016Jumping genes, so-called transposons, reproduce as parasites in the genome. This selfish behavior can be an evolutionary advantage for the organism or harm it. There is still a debate about the factors controlling the activity of transposons.
16/09/2016Researchers at the National Cancer Institute in the USA and the Babraham Institute, UK, have discovered how a mineral ion leaked from tumour tissue as it dies acts to stop the work of anti-tumour immune cells. This discovery provides a new approach in the development of treatments to engage the immune system in the fight against cancer.
13/09/2016Specifically training oncologists and their patients to have high-quality discussions improves communication, but troubling gaps still exist between the two groups, according to a new study in "JAMA Oncology".
12/09/2016Individual cells within a tumor are not all the same. This may sound like a modern medical truism, but it wasn't very long ago that oncologists assumed that taking a single biopsy from a patient's tumor would be an accurate reflection of the physiological and genetic make-up of the entire mass.
09/09/2016Researchers at the University of Adelaide have shown how a complex mix of plant compounds derived from ancient clinical practice in China – a Traditional Chinese Medicine – works to kill cancer cells.
08/09/2016Researchers discover a signalling pathway that enables cells to reach their destinations through repulsion.
08/09/2016A receptor for the dopamine neurotransmitter promotes growth and spread of pancreatic cancer -- and schizophrenia drugs, which block the function of this receptor, slowed tumor growth and metastatic spread in mice, according to researchers at McGill University and the German Cancer Research Center.
07/09/2016Potential outbreaks of diseases such as Ebola and Lassa fever may be more accurately predicted thanks to a new mathematical model developed by researchers at the University of Cambridge. This could in turn help inform public health messages to prevent outbreaks spreading more widely.
30/08/2016Researchers at Houston Methodist have developed an artificial intelligence (AI) software that reliably interprets mammograms, assisting doctors with a quick and accurate prediction of breast cancer risk.
24/08/2016According to new research, green tea could prevent a deadly condition in the body's main artery. A Kyoto University team has found that abdominal aortic aneurysm - a condition in which the main artery becomes overstretched and bloated - developed less frequently in rats that drank green tea polyphenol, a major component of green tea.
24/08/2016A discovery in the field of biomaterials may open new frontiers in stem and cancer cell manipulation and associated advanced therapy development. Novel scaffolds are shown enabling cells to behave in a different but controlled way in vitro due to the presence of aligned, self-assembled ceramic nanofibers of an ultra-high anisotropy ratio augmented into graphene shells.
23/08/2016Combining ultrasound energy and microbubbles to poke holes in cells may prove to be a new tool in the fight against cardiovascular disease and cancer, according to researchers from the University of Pittsburgh and UPMC. A study on this gene therapy approach, called sonoporation, is published in the Proceedings of the National Academy of Sciences (PNAS).

14/07/2016Researchers at MIT's research center in Singapore have developed a new microfluidic device that tests the effects of electric fields on cancer cells. They observed that a range of low-intensity, middle-frequency electric fields effectively stopped breast and lung cancer cells from growing and spreading, while having no adverse effect on neighboring healthy cells.
07/07/2016In colorectal cancer, the presence of invasive tumor cells at the advancing edge of the tumor can provide valuable information on prognosis. Initiated by the Colorectal Cancer Research Group at the Institute of Pathology, University of Bern, a consensus conference was held to determine how this phenomenon should best be put into practice.
07/07/2016When a woman is diagnosed with the earliest stage of breast cancer, how aggressive should her treatment be? Will the non-invasive cancer become invasive? Or is it a slow-growing variety that will likely never be harmful?
05/07/2016In a meta-analysis of hundreds of clinical trials involving thousands of patients, researchers at University of California San Diego School of Medicine report that therapeutic approaches using precision medicine, which emphasizes the use of individual genetics to refine cancer treatment, showed improved response and longer periods of disease remission, even in phase I trials.
22/03/2016Medical apps like diabetes or high blood pressure diaries are becoming increasingly popular with smartphone users. There are many available choices out there but they are not always clear. Added to this is the question of how the data collected by the apps can be sensibly incorporated into treatment.
08/03/2016Pancreatic cancer is one of the deadliest forms of cancer because it is difficult to diagnose and only presents with symptoms in the later stages. In the future, a laboratory test developed at the Greifswald University Medicine could make an early detection of this type of cancer and consequently a faster and better treatment possible.
09/11/2015Interview with Professor Jürgen Weitz, Director of the Clinic and Polyclinic of Visceral, Thoracic, and Vascular Surgery, University Hospital Carl Gustav Carus at the Technical University Dresden
01/10/2015A proper diagnosis is a part of great therapy. However, it can also be beneficial to be able to quickly respond to changes during a treatment. One example of this is the treatment of uterine myomas. Female patients at the University Hospital Bonn are treated using so-called high-intensity focused ultrasound, HIFU in short. Prof. Holger Strunk explains this procedure.
01/10/2015Semiconductor nanoparticles for biomedical applications have been researched for some time now. Not only are they millionths of a millimeter in size, they also offer great potential for cancer diagnostics and therapy, so-called theranostics. They enter cells, are activated by ultrasonic radiation and destroy the cells using the generated vibration.
01/10/2015It is a portmanteau, a mixture of two words. This way it saves us time and trouble while speaking because the human speech apparatus is lazy. And it describes a mixture of procedures: the combination of two procedures that would normally be separate in medicine. We are talking about theranostics.
03/08/2015Endoradiotherapy can be very unpleasant for cancer patients, since it does not only harm tumor cells, but also healthy ones. Sometimes, patients even need to stop therapy because of the side effects. Physicians and researchers are thus continuously searching for ways to transport radiopharmaceuticals directly and exclusively to their target.
22/06/2015Bladder tumors have different growth characteristics. In most cases, they are limited to the inner wall of the bladder and thus well resectable. Unlike carcinoma in situ, which becomes muscle invasive after a certain amount of time. To be able to completely remove the tumor during resection, photodynamic diagnostics (PDD) can make sense.
01/06/2015A tumor is as unique as the person who is affected by it. For a long time, it was assumed this would make treatment more difficult since cancer drugs are not able to be one hundred percent effective in targeting the affected cells. In this interview with MEDICA.de, Professor Ugur Sahin explains why it is precisely these individual mutations that make him hopeful for a new type of therapy.
01/06/2015Can liquid biopsies become the new trend in cancer diagnostics? The medical world has asked this question for quite some time. The first globally approved liquid biopsy-based test for lung cancer shows that this can work. Yet further findings and research are still required to establish this less invasive method in diagnostics.
01/06/2015When cancer is diagnosed, the terms tumor markers or biomarkers keep popping up. They describe characteristics that are not found in healthy persons. The classic tumor markers can be easily detected in blood samples or other body fluids. Other analysis methods require more effort. Yet they all share one thing in common: biomarkers indicate a potential tumor.
04/05/2015There are many decisions to be made in an adult life; among them are cancer prevention screenings. They are voluntary and many people deliberate whether they should go or not and if they would actually want to know the results. Science, politics and health care professionals also ponder with each new preventive service whether it is beneficial and who should end up paying for it.
04/05/2015Whether it is a mammogram, colonoscopy or a skin cancer screening – after a certain age, we are subject to various early cancer detection screenings. Yet many of us don’t know that these screening tests are also associated with risks. This is something what Dr. Sylvia Sänger from the University Medical Center Hamburg-Eppendorf discovered in a study.
04/05/2015Since the end of April 2015, the long-awaited evaluation report on the skin cancer screening programs offered by German health insurance providers is now finally available. We spoke with Dr. Ralph von Kiedrowski, Board Member of the German Dermatologist Association (German: Berufsverband Deutscher Dermatologen) on what the screening can accomplish and his take on the G-BA report.
02/02/2015Only projects with a solid foundation are successful in the long run. This is also true for science. Biobanks are the most important component of this foundation when it comes to fundamental biomedical research: Only high quality tissue samples that are stored there make conclusive research possible - for example in search of the causes of tumorigenesis.
03/11/2014As an imaging procedure, magnetic resonance tomography has become essential in clinical practice, since it can easily make organs and tissue visible. However, until now abnormal cancer cells or small centers of inflammation remained almost invisible. Now cell biologists from Berlin, Germany, have succeeded in fixing this problem with xenon magnetic resonance imaging.
03/02/2014Shortening a time-consuming procedure from four hours to five minutes and automate it at the same time sounds like a dream come true for employees in all fields and industry sectors. This dream could soon become a reality for radiologists. Software could take away the tedious processing of CT images, which is required before cancer radiation therapy.
03/02/2014Radiologists usually do their work after oncologists when it comes to cancer treatment. Yet modern radiology also provides treatments at this point. MEDICA.de spoke with Professor Stefan Schönberg, Director of the Institute of Clinical Radiology and Nuclear Medicine at the University Medical Center Mannheim, Germany, about the use of a new computer tomograph and its benefits for patients.
03/02/2014Differentiating tumor tissue from healthy tissue isn’t always easy for surgeons. Scattered cancer cells and early cancer are often hard to detect with the naked eye. A special camera now makes even the tiniest remainder of a tumor visible during surgery.
05/01/2014Eventually, all adults need to see a physician for colon cancer prevention. While the exam goes by quickly thanks to sedation, it sometimes leads to a follow-up procedure if a growth in the colon could not be removed with the endoscope and requires open surgery.
