Show your support for cancer research with our selection of cancer awareness watches. Aside from breast cancer with the pink ribbon, other symbols to show support of cancer research include a gray ribbon for brain cancer research; a blue ribbon for colon cancer awareness; a yellow ribbon for kidney cancer awareness; a red ribbon for support of leukemia; a white ribbon for lung cancer support; and a green ribbon in support of lymphoma research. All of these watches faces come as a sterling silver watch face with a square watch face frame. To attach to either a watchband or a bracelet, these cancer awareness watches have loop attachments. Aside from cancer awareness, watch faces in this category can come printed with a yellow ribbon, which can signify support for troops overseas or for suicide prevention.
