Many cases of early-stage kidney cancer can be treated with a relatively new, nonsurgical procedure used to destroy tumors, a study by a team led by Weill Cornell Medicine and NewYork-Presbyterian suggests. The procedure, called percutaneous ablation, involves the insertion of a needle through the skin into a kidney tumor, […]

A tumor’s goal is simple: to grow, grow, grow, by making more cancer cells. But that often means growing so fast that the oxygen supply gets scarce, at which point cells within the tumor start to suffocate. Without oxygen, these ever-dividing cells struggle to make enough aspartate, a crucial ingredient […]

Remove tumor cells from a living organism and place them in a dish, and they will multiply even faster than before. The mystery of why this is has long stumped cancer researchers, though many have simply focused on the mutations and chains of molecular reactions that could prompt such a […]

Men with non-metastatic castrate-resistant prostate cancer and a quickly rising PSA level present a medical dilemma. The rising PSA (prostate-specific antigen) means there is cancer activity, but no visible metastasis in a scan. These men are receiving hormone treatments to reduce the testosterone on which their cancer feeds, but their cancers […]

Need to kill tumors? Just add heat. That’s the promise of heated magnetic nanoparticles, a futuristic-sounding technology that could one day be used to fry and eradicate cancer cells without harming healthy tissue elsewhere in the body. New research led by the University at Buffalo advances this concept, with scientists […]

A new Tel Aviv University study explores a novel smart probe for image-guided surgery that may dramatically improve post-surgical outcomes for cancer patients. In many kinds of cancers, it is often not the primary malignant tumor, but rather metastasis — the spread of lingering cancer cells to other parts of the body […]

People with a slow developing type of blood cancer may be able to safely come off  ‘life-long’ daily treatment in the future and remain free from cancer, the latest results from a University of Liverpool clinical trial suggest.
