Dear Marmam community, On behalf of my co-authors, I are pleased to announce our recent publication in the Journal of Mammary Gland Biology and Neoplasia: Robles-Malagamba, M.J., Gerussi, T., Sánchez-Contreras, G.J. et al. Imaging and Diagnostic Tools for Cetacean Mammary Gland Assessment: Challenges and Future Directions for Marine Mammal Pathology, Medicine and Research. J Mammary Gland Biol Neoplasia 31, 3 (2026). This review paper describes current diagnostic tools applied in human and veterinary medicine to assess mammary glands and how marine mammal medicine could benefit from incorporating these tools into standard evaluation of the mammary glands in free-ranging and captive cetaceans. By evaluating the strengths and weaknesses of the current tools used to assess the mammary glands in humans and domestic animals —such as mammography, CT, MRI and ultrasonography— we frame a collection of diagnostic approaches that might be adapted to the particular challenges faced by marine mammal veterinarians, to enhance the evaluation of cetacean mammary gland morphology, physiology and development.
