Oftentimes patients see their doctors with concerns about new changes in the structure of their tissues—patients found a lump, or have a weird looking mole. Sometimes these lesions can become cancerous, but other times they just sit dormant for years or even decades without becoming cancerous. So the physician must make a decision: treat these early-stage abnormalities like full-blown cancer, complete with the invasive and side effects that are difficult to endure, or ignore the abnormality and wait to treat it when it becomes problematic and cancerous. Since the cancers are easier to treat in their early stages, many physicians have chosen the first, aggressive option. But as a result many patients have developed different cancers later on that are even more resistant to treatment. If researchers could make a 3D model of these early lesions, they might be able to better understand how the tumor responds to forces, and how the cells communicate with one another, to determine if they will later become cancerous. These models could also help oncologists treat tumors at their most important points, so that drugs can pack the most punch. But each type of tissue looks and acts a bit differently, so they would need many different models.
