Lewis lung carcinoma
Lewis lung carcinoma is a tumor discovered by Dr. Margaret R. Lewis of the Wistar Institute in 1951. This tumor originated spontaneously as a carcinoma of the lung of a C57BL mouse. The tumor does not appear to be grossly hemorrhagic and the majority of the tumor tissue is a semifirm homogeneous mass. It is also called 3LL and LLC and is used as a transplantable malignancy. It has been used in many studies.
