You are cordially invited to participate in the second meeting on Cancer Biology & Therapeutics to be held at Cold Spring Harbor Laboratory, New York. The meeting will begin on Tuesday, April 23, 2013, and will conclude with lunch on Saturday, April 27. The specific goal of this conference is to bring together a diverse group of scientists studying various aspects of the biology of cancer. The meeting will alternate annually with the CSHL meeting on Mechanisms & Models of Cancer. The format of the meeting will include morning and evening sessions consisting of eight or nine 15-minute talks per session, selected from the abstracts, principally on unpublished work. In addition, there will be two poster sessions, held in the afternoons. The organizers will decide the suitability of each abstract for oral or poster presentation, but please specify if you prefer a poster.
