Advances in Cancer Research provides invaluable information on the exciting and fast-moving field of cancer research. Here, once again, outstanding and original reviews are presented on a variety of topics, including platelet-derived growth factor in disease, genetic predisposition in tumor development, primary effusion lymphoma, and many more.Cancer is not one disease, but a group of diseases in which malignant cells grow out of control and spread to other parts of the body.
