Tonight at 10PM, HBO is airing Killing Cancer, our special report on the cancer researchers working tirelessly to come up with a cure for the disease at the Mayo Clinic Cancer Center. In the report, we take a look inside the world's most cutting-edge cancer research labs and the doctors working with them. We also speak with cancer survivors who owe their recovery to the Mayo Clinic's revolutionary work in the cancer treatment field.VICE co-founder Shane Smith has dealt directly with the pain of watching a loved one struggle with cancer. In honor of his mother, who recently survived the disease, Shane has established a gift-matching campaign to help the Mayo Clinic continue forward with their groundbreaking cancer research.Every donation made from today until April 28 will be matched by Shane, up to a total of $500,000. What that means is that, if everyone donates now, the Mayo Clinic could recieve a million dollars by the end of April.Head over to the Mayo Clinic donation page, contribute, and then get an in-depth look at the research you're supporting in tonight's Killing Cancer report.The third season of our HBO show premieres March 6, but you can watch episodes from the second season right now, for free.
