What are the challenges in cancer detection and quantification?
Despite advancements, several challenges remain:
False positives and negatives: Imaging and blood tests can sometimes yield inaccurate results, leading to unnecessary anxiety or missed diagnoses. Heterogeneity: Tumors can vary greatly within the same type of cancer, complicating detection and treatment. Accessibility: Advanced diagnostic tools and genetic tests may not be available in all regions, limiting early detection efforts. Cost: High costs associated with advanced diagnostic techniques can be a barrier for many patients.
