I can't name the research on this topic off of the top of my head, but yes to both questions. Cancer is a common occurence in all mammals and we have evolved many self defense mechanisms, including telomeres, to fight it as animals started living longer and longer. One of the most promising areas of oncology research is immunotherapy, for example, which guides your immune system to attack cancer cells that havent been recognized as targets.
