The video “Fluss aufwärts” [Going upstream] tells the story of a TB screening program in Mexico. To reach people in remote regions of the country, a ship equipped with a complete photofluorography unit traveled to distant villages.

If lung cancer is detected in the early stages (stage 1–2), it has a five-year survival rate of 70–90 percent. If it is diagnosed at a later stage, 85–90 percent of patients die within five years of diagnosis.

Evaluating small-format images captured during mass X-ray screening was a very laborious process, as physicians had to examine the images one by one in front of a light box using a magnifying glass. Nowadays, the evaluation of clinical images has become much easier thanks to digitalization and tools powered by AI.
