Special Issue Information
Tumor development occurs as a multistep process driven by the selection of accumulating variations. In 1990, Fearon and Vogelstein formulated a stepwise unifying model to describe tumor initiation and evolution, in which tumorigenesis and acquisition of malignant properties occur as the result of a defined sequence of genetic and epigenetic alterations. Indeed, oncogenic mutations can alter the homeostatic equilibrium of the cells in a given tissue and set the stage for the accumulation of further alterations associated with the progression of the disease. During the last three decades, this model has been tremendously complexified by an impressive amount of findings. Cancer development is currently known to be associated with the rise and dynamic evolution of multiple subclones that can co-exist as parts of a complex ecosystem. Additionally, cancer progression is supported by noncancerous cells, such as tumor-associated fibroblasts, immune cells, and by the microbiome that populates the tumor microenvironment. This heterogeneity controls the many-sided capacity of cancer cells to grow, disseminate, resist different treatments, escape immune response, and relapse. Understanding the bases of tumor evolution and heterogeneity represents one the greatest challenges in modern medicine and biomedical research.
In this Special Issue, we invite researchers to bridge the gap and tackle tumor evolution from different complementary angles, across a broad range of tumor types. We welcome review, research, and method manuscripts covering the areas of genetics and epigenetics of oncogenesis, invasion, resistance to treatments, as well as the role of the tumor microenvironment in these aspects.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biology is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
