This led to some interesting discoveries. On day 35, some rabbits began to show the initial signs of cancer, 12 days later some rabbits developed full-blown cancer, and by day 150, cancer was evident in all the rabbits. The cancer turned out to be squamous cell carcinoma, the same type that tends to appear in sun-exposed areas of the body.</p> Tue, 12 Apr 2022 16:37:13 +0000 Nancy Liu-Sullivan, PhD 9080 at /oss
