This invention discloses a method and system for constructing a gastric cancer risk prediction model using a joint segmentation and classification network. The method first preprocesses gastroscopy, CT, or pathological images. Then, a front-end routing network dynamically selects either a first prediction model based on UNet+morphological attention modules or a second prediction model based on Swing Transformer for analysis, based on image clarity, complexity, and lesion characteristics. When an input image is detected as a clinically high-risk case, both models are directly used for parallel discrimination. If the confidence level of a single model is higher than a preset threshold, its result is directly output; if the confidence level is insufficient, the other model is automatically invoked, and an arbitrator fuses the results of the two models to provide a final judgment. The arbitrator dynamically adjusts the fusion weights based on the confidence levels of the two models and the consistency of the segmentation mask, thereby generating a reliable final gastric cancer risk prediction result.
