A mathematical model of tumor growth has been developed

Physicist Sihui Tsoi of Heidelberg University in Germany, together with colleagues, developed a mathematical model of how the tumor will develop. The scientists analyzed detailed images of tumors taken from cancer-infected mice and the blood vessels that feed them at different stages of development.
