Author Sheila Wyborny thoughtfully introduces readers to Hodgkin’s disease, which is one of the cancers of the immune system. In the United States, it is the most common cancer in teens from age 15 to 19 and occurs most often in people between the ages of 15 and 40 and after the age of 55. Readers will gain insight into what it is, what causes it, how people live with it and the latest information about treatment and prevention.
