...other drugs, plus cyclophosphamide. Tamoxifen is a drug that counters the effect of estrogen, a hormone linked to breast tumors. Disease-free survival after five years was 85 percent for the women receiving only tamoxifen, while the rate was...
...Cell, a research team led by Stanley Cohen reported that a gene called "TSG101" is abnormal in about half of the breast tumors tested. While much attention has focused lately on inherited genes that can contribute to breast cancer, "TSG101...
...Detmar, postdoctoral fellow Mihaela Skobe and colleagues were able to see networks of lymphatic vessels deep inside breast tumor masses grown in mice. Looking closer, they found the vessels appeared to be carrying tumor cells. The number of lymphatic...
