Participation in the study will include one study visit of approximately 2.5 hours. If possible, the study visit will be combined with a regular follow-up visit. Vena puncture is the only invasive procedure, with low risk of adverse effects. Blood will be drawn after an overnight fast. To minimize the duration of the visit, patients will be offered to fill out the questionnaires at home. Individual adverse test results will be reported to a participants' treating physician to enable treatment or follow-up as indicated. The results of the full study group will be used to guide future interventions and support for melanoma and NSCLC patients.
