CANCER LETTERS is a journal providing rapid publication of full-length articles in the broad area of cancer research. The journal places emphasis on the molecular and cell biology of cancer, oncogenes, carcinogenesis, radiation biology, molecular pathology, hormones and cancer, viral oncology, biology of cancer and metastasis, molecular cytogenetics, epidemiology; and experimental therapeutics. The primary criterion for publication is interest to a multidisciplinary audience. Papers should be technically sound and substantiated by sufficient experimental detail. Clinical papers will be accepted if they contribute to the understanding of the basic mechanisms underlying disease.
