World's Oldest-Known Living Cancer Found in Dogs
The world's oldest-known living cancer was discovered in a dog, dating back 11,000 years despite numerous genetic changes. The cancer cells are transmitted between animals when they mate and revealed the genetics of an ancient husky-like dog where the disease originated. A team at Wellcome Trust Sanger Institute near Cambridge decoded the DNA of the cancer. The dog-transmission cancer is rare and causes genital tumors. Hopefully, the genome of the cancer will allow scientists to understand how cancers become transmissible.
