Dear Dr. Din, Thank you for reaching out. To participate we ask you to write either an original research paper or a review paper based on your latest research. Your paper would be published as an Open Access chapter in this book. Your submission can be a theoretical or an applied scientific paper or a review paper. Some potential research subjects and keywords are: Metastasis, Recurrence, Immune Evasion, Heterogeneity, Chemotherapy. Please note that the keywords are here to guide you, but you don't have to strictly adhere to them, you are welcome to write about any topic as long as it falls under the scope of the book. For the participation process, your first step should be to complete your registration and accept the Terms and Conditions, including the Chapter Processing Charge*. You will then be asked to submit a chapter proposal, which should consist of a title, 5-6 keywords, and a short summary (100-150 words) of your future full chapter. Feel free to write about any topic that interests you, as long as it fits the scope of the book. Only after the editor's approval of your proposal will you proceed to write a full chapter that should be 10-20 pages long. Upon registration, you will gain access to your Author Panel, where you can find all the important guidelines, documents, and more detailed instructions regarding the publishing process steps. As an author, you have two deadlines to follow. The first one is the chapter proposal deadline, due on April 17, 2024, and the second is the deadline for the full chapter, which is due on June 14, 2024.
