The unpredictability of cancer possesses a threat to personalized cures. Although cancer is studied as a chaotic system, the shape of its unpredictability is unclear. This unpredictability develops from missing information gathered over many cell divisions. Here, using techniques from cubism and abstract expressionism, I represent the unpredictability of cancer. The trajectory that cancer cells follow in terms of their common biological attributes, twists and turns in a high dimensional space. This cognitive art-science model puts forward the idea that all the biological attributes of cancer should be studied in single-cell level.
