Fallopian tube cancer, which typically arises from the epithelial lining of the fallopian tube, has historically been considered to be a very rare malignancy. Recent evidence suggests it probably represents a significant portion of what has been classified as ovarian cancer in the past. While tubal cancers may be misdiagnosed as ovarian cancer, it is of little consequence as the treatment of both ovarian and fallopian tube cancer is similar.
