| \\ | At [[1a_questionnaire_1|1A]], [[1b|1B]], [[1c|1C]], [[2a_questionnaire_1|2A]], and [[3a_questionnaire_1|3A]] type of cancer (tumor) was reported by participants in an open text field. From 2A onwards a limited number of cancer types (i.e., colon cancer, lung cancer, skin cancer, brain tumor, bone cancer, breast cancer, and prostate cancer) are also directly assessed via yes/no questions. At [[3b|3B]] only these direct cancer type questions are used, there is no open text field. Researchers from the University Medical Center Groningen coded these [[cancer|self-reported cancer variables]] into 35 cancer type categories. The secondary cancer type variables will be added to the [[https://data-catalogue.lifelines.nl/|Lifelines catalogue]] very soon. |
