When a malignant tumor sets up camp somewhere in the human body, it requires a generous supply of blood in order to survive and grow. Cancer cells secure this supply by somehow encouraging angiogenesis, the proliferation of networks of tiny capillaries, which connect the incipient tumor to nearby arteries and veins. But what are the signals that entice the blood vessels to leave their established pathways and converge on a tumor? Scientists have sought the answer to that question for years. If such signals could be blocked, they reasoned, the tumor would no longer grow...
Tamoxifen's effectiveness stems from the fact that the proliferation of breast-cancer cells in two-thirds of older women seems dependent on estrogen, the female sex hormone. The drug acts by blocking receptors for estrogen on the surfaces of cells that have migrated from the breast tumor, thus halting the division of the cells and preventing them from seeding tumors in other parts of the body. Unlike conventional chemotherapy, which usually causes loss of hair and severe nausea, tamoxifen produces only minor side effects, such as hot flashes and mild nausea, and only in about one-quarter of patients...
