Starving cancer cells of nutrients halts tumour growth

There are more than 900 different types of cancer currently identified, and many of them require very specific treatments, and can become resistant to chemotherapy as time goes on. Now, researchers at the Australian National University (ANU) have made a potentially huge breakthrough, working out how to cut off the supply of vital nutrients to cancer cells. The work opens the door to future treatments that could be less prone to resistance than many current methods, and could work across with a wide range of cancers.Read More

Tool matches cancer genetics to approved treatments

When treating cancer, it's difficult to know whether a chosen treatment is proving effective. While new breakthroughs may give doctors faster indications of whether drugs are working, by the time a new treatment is attempted, it might be too late to achieve a positive outcome. A new tool, developed by researchers at the University of Colorado, could have a big impact on which treatment doctors decide to use, using data from whole exome sequencing to pick out drugs likely to prove effective at tackling tumors on a case-by-case basis.Read More

Nanoparticle "cluster bombs" could provide less toxic chemotherapy

Doctors have been using the chemotherapy drug cisplatin for decades, but significant toxic side effects – which can affect everything from the kidneys to the inner ear – limit its effectiveness as a treatment. A new method, which makes use of innovative nanoparticles, could change that, providing a "cluster bomb" approach to delivery that shows signs of being significantly less toxic to the patient.Read More

Nanoparticle shows if cancer treatment is working, ASAP

Knowing whether a therapy is working effectively is extremely important when treating cancer. That information can have a big impact, potentially prompting a change in treatment and improving its outcome. Right now, we don't have a method of detecting whether a tumor is reacting to medication until numerous cycles of therapy have been completed, but research by scientists at Brigham and Women's Hospital (BWH) could change that, with a new nanoparticle treatment providing the information in as little as eight hours.Read More

Microneedle patch drip feeds cancer drugs directly into melanomas

The emerging field of immunotherapy has uncovered some powerful new weapons in the fight against cancer, but tumor cells can be quite crafty in the way they go undetected by our immune system. In an advance that could play a part in neutralizing these stealthy attributes, researchers have developed a microneedle patch that can be worn on the skin to more effectively deliver immunotherapy drugs directly to the site of a melanoma.Read More

Protective bubble ferries prostate cancer drugs to their target

Research has uncovered a number of promising drug targets to halt the progression of prostate cancer, including proteins that inhibit the immune response to molecules that drive growth of a tumor's blood vessels. By taking aim at one protein in particular, scientists have been able slow the growth of prostate cancer in mice and also activate a kill switch in the tumor's cells.Read More

Silencing breast and lung cancer's ability to spread

As a tumor grows, cells can break off it and move around the body, potentially spreading the disease to other organs. Known as metastasis, this process significantly lowers the patient's likelihood of survival, but a new discovery could help doctors tackle it, with researchers form Imperial College London identifying a molecule that shows promise in switching off the process altogether.Read More

Fruit and veg intake shown to have long-lasting benefits in cutting breast cancer risk

The general health benefits of eating fruit and vegetables are well known, but researchers have provided young women with yet another reason to eat their greens. A large-scale study carried out by the Harvard T.H. Chan School of Public Health, which followed thousands of women for several years, has found a strong correlation between a high-fiber diet during adolescence and young adulthood and a reduced risk of developing breast cancer later in life.Read More

Light reflectance fine tunes prostate cancer surgery

When a patient is diagnosed with prostate cancer, doctors often decide to remove the gland and some of the surrounding tissue, but the procedure isn't always perfect, and in some cases either too little or too much tissue is removed. A new technique might significantly improve the accuracy of the procedure, using a reflected light technology to detect left-behind cancer cells during the surgery.Read More
