Second lumpectomy for breast cancer reduces survival rates

(SACRAMENTO, Calif.) A majority of women with breast cancer today are candidates for lumpectomy, allowing for conservation of most of their breast tissue. Results of a UC Davis study, however, show that a number of women whose cancer recurs in the same breast are treated with a second lumpectomy ...

Forest canopies help determine natural fertilization rates
