Tumors require a blood supply to grow, but how they acquire their network of blood vessels is poorly understood. A new study here shows that tumor blood vessels can develop from precancerous stem cells, a recently discovered type of cell that can either remain benign or become malignant.
Researchers here have shown that in cell cultures, the stress hormone norepinephrine appears to promote the biochemical signals that stimulate certain tumor cells to grow and spread.
Non-steroidal anti-inflammatory drugs (NSAIDs), especially aspirin, may decrease the risk of bladder cancer according to a new study led by Dr. Margaret Karagas of Dartmouth Medical School.
