Cancer awareness colors for summer months include purple for cancer survivors in June, yellow for bone cancer in July and light blue for prostate cancer in September. There are no cancer awareness campaigns in August, notes Cancer.net, the American Society of Clinical Oncology's patient information website.
Most cancer organizations use colored ribbons or wristbands to raise awareness and funds. Lavender or light purple in June represents all cancer types and survivors, according to About.com. Yellow in July represents sarcoma. September has the most summer cancer awareness campaigns, with orange for leukemia, teal for ovarian cancer and light blue for prostate cancer. A light-pink-and-baby-blue ribbon represents men's breast cancer in June, adds Cancer.net.
