Source of cancer stem cells' resistance to radiation discovered

Much to the dismay of patients and physicians, cancer stem cells - tiny powerhouses that generate and maintain tumor growth in many types of cancers - are relatively resistant to the ionizing radiation often used as therapy for these conditions.

Radiofrequency treatment better than ethanol injection for small liver tumors

A new review of four randomized controlled trials that directly compared two different treatments for small inoperable liver tumors has found that radiofrequency ablation (RFA) significantly improves patient survival compared to the standard therapy of percutaneous ethanol injection (PEI).

MR spectroscopy may help avoid invasive procedures and treatments for recurrent brain lesions

A clinical decision model which uses MR spectroscopy to help physicians differentiate between recurrent tumors and changes in the brain tissue due to radiation treatments, may help patients avoid invasive procedures and treatments, according to a study performed at the University of Michigan Health System in Ann Arbor, MI.

Diet high in inorganic phosphates increases risk of lung cancer

New research in an animal model suggests that a diet high in inorganic phosphates, which are found in a variety of processed foods including meats, cheeses, beverages, and bakery products, might speed growth of lung cancer tumors and may even contribute to the development of those tumors in individuals predisposed to the disease.
