Seema Khan, MD, professor of surgery, found a new skin gel that reduced the growth of cancer cells minimizing dangerous side effects. A gel form of tamoxifen applied to the breasts of women with noninvasive breast cancer reduced the growth of cancer cells to the same degree as the drug taken in oral form but with fewer side effects that deter some women from taking it, according to new Northwestern Medicine research.
Tamoxifen is an oral drug that is used for breast cancer prevention and as therapy for non-invasive breast cancer and invasive cancer. Because the drug was absorbed through the skin directly into breast tissue, blood levels of the drug were much lower, thus, potentially minimizing dangerous side effects — blood clots and uterine cancer.
