Abstract This article summarizes the overall issues surrounding cancer for the general audience. Individual differences between patients include genetic and non-genetic differences manifested in various cellular pathways, tumor heterogeneity and variability, differing contribution of tumor microenvironment and potential toward metastasis. Successful treatment of individuals depends on correctly interpreting all these factors and appropriately addressing the actual features by using customized therapy strategies, simultaneously or sequentially. Currently used chemotherapy agents are cytotoxic and typically target one of the major pathways; therefore they have to be applied in combination regimes. Nanomedicines however, have the potential advantage that more than one feature can be built into a complex nanodevice. This yet untapped potential is illustrated on the example of a gadolinium fullerenol cage molecule. Gd@C 82OH 22 has low toxicity, influences several biologic features simultaneously, displays tumoristatic properties, and is effective against triple-negative breast cancer cells. A deeper understanding of the exact relations between the physicochemical characteristics of this system and the biologic events may lead to a new class of efficient anticancer pharmaceutics. From the Clinical Editor The search for the magic bullet in the treatment of cancer has long been the dream of clinicians and researchers worldwide. Inherent cellular characteristics of cancer cells have made this task extremely hard to reach. In this article, the author provided a concise summary on the understanding and challenges in the current battle and also illustrated the potential usefulness of the recently developed gadolinium fullerenol cage molecule by describing experimental data from various research groups.
