Cancer Research:Researchers disguise drugs as platelets to target cancer ♦ New dual strategy halts cell division ♦ Risk factors for prostate cancer

Researchers disguise drugs as platelets to target cancer Researchers have for the first time developed a technique that coats anticancer drugs in membranes made from a patient's own platelets, allowing the drugs to last longer in the body and attack both primary cancer tumors and the circulating tumor cells that can cause a cancer to metastasize.
Targeted cancer treatment: New dual strategy halts cell division A team of researchers has confirmed in a recent study its new concept for the targeted treatment of ovarian cancer. The concept is intended to better control the development of resistance and improve treatment outcomes. The strategy focuses on halting tumor growth by inhibiting two signal networks instead of just one.
Doctors often over treated with radiation in late-stage lung cancer Almost half of patients with advanced lung cancer receive more than the recommended number of radiation treatments to reduce their pain, according to a new study. Radiation therapy that is palliative, or not intended to cure, can reduce the pain from lung tumors and improve quality of life. But unnecessary treatments add to costs and require needless trips to the hospital -- and can lead to radiation toxicity and difficulty in swallowing.
Sniffing out cancer with improved 'electronic nose' sensors Scientists have been exploring new ways to 'smell' signs of cancer by analyzing what's in patients' breath. In a new study, one team now reports new progress toward this goal. The researchers have developed a small array of flexible sensors, which accurately detect compounds in breath samples that are specific to ovarian cancer
Risk factors for prostate cancer New research suggests that age, race and family history are the biggest risk factors for a man to develop prostate cancer, although high blood pressure, high cholesterol, vitamin D deficiency, inflammation of prostate, and vasectomy also add to the risk. In contrast, obesity, alcohol abuse, and smoking show a negative association with the disease.
