DEAR DOCTOR K: I read about a study that said married cancer patients do better than those who aren't married. Why does marriage have such a positive effect?
DEAR READER: You're probably talking about a study that was published earlier this year in the Journal of Clinical Oncology. The study included about 735,000 people diagnosed with 10 different types of cancer. Married men were 23 percent less likely to die of cancer than those who were single, widowed or divorced.
