"The Endocrine Society appreciates the opportunity to comment on the National Cancer Institute’s (NCI) support of early career, mentored cancer researchers and trainees. Founded in 1916, the Endocrine Society is the world’s oldest, largest, and most active organization dedicated to research on hormones and the clinical practice of endocrinology. Our membership consists of over 18,000 scientists, physicians, educators, nurses, and students in more than 100 countries. Society members represent all basic, applied and clinical interests in endocrinology. Many of our members are funded by NCI to study hormone-sensitive cancers, endocrine neoplasias, and other research interests central to NCI’s mission. Our members also serve as mentors and mentees on training grants, and we are enthusiastic about opportunities to improve the environment for researchers at the formative stages of their careers."
