In the second programme of the series von Hagens and Lee take a look at cancer. They illuminate the difficulties of diagnosing and treating a disease that is a result of the body's own cells multiplying uncontrollably. Von Hagens dissects a woman who died of bowel cancer to reveal the site of the primary tumour and the other parts of her body that it affected. He also reveals the silent spread of tumours in the frozen body of a woman who died from breast cancer.
