Warum Wale und Elefanten keinen Krebs bekommen

Every day, thousands of cancer cells are produced in our bodies, which are destroyed by our immune system.  But tumor cells have developed a sophisticated escape strategy to evade the immune system: these tumor cells undergo training in special "training camps." Cancer development is fueled by tumor stem cells, which are hidden throughout the body and constantly supply a steady stream of new cancer cells. These stem cells evade every form of cancer therapy. Genes are behind all these processes. Are we powerless against our genes, or can we influence them through our lifestyle? Why do some animals not get cancer, but humans do?  The final chapter is devoted to modern "targeted cancer therapies" and the question of whether cancer can be defeated.
