'I don't know when it's my turn': reasons for low uptake of cancer-related healthcare services in Germany.

Germany also provides a variety of these services free-of-charge under its highly subsidized public healthcare system. This qualitative study aimed to determine the barriers perceived or experienced by service users in Germany against utilizing cancer screenings and treatment services.
