Tumor ancestral trees are physically embedded within their tumors

In cancer treatment, metastatic tumors receive equal treatment.  Patients are given the same aggressive therapies when abnormal clusters of cells are discovered early, even if they may be harmless.  In research studies co-led by Duke's Marc Ryser... read more »


New Approach to Bone Remodeling

Kevin Murgas (Biomedical Engineering, Class 2017), started working on this project during a Research Experience for Undergraduates (REU) program in mathematical biology in the summer of 2015. Together with his research mentor, Dr. Marc Ryser, they... read more »


Study: Vaccinating Boys Against HPV Could Prevent Cancer In Men and Women

A mathematical model from Duke University mathematicians suggests more can be done to protect people from the human papilloma virus.    HPV is associated with cervical cancer in women, but can also cause various cancers in men.   Duke mathematician... read more »


Mathematical model suggests select DCIS patients could delay treatment

Active surveillance could be a viable alternative to surgery and radiation for select patients with ductal carcinoma in situ, or DCIS, according to a mathematical model developed by researchers at Duke University.... read more »
