Hi,
In my Materia Medicas I have only found this remedies:
Cadmium Bromatum
Cadmium Flourata
Cadmium Iodatum
Cadmium Metallicum and
Cadmium Sulphuratum

Cadmium flourata is indicated in cases of cancer in prostata; Cadmium Iodatum ans Metallicum too, but without precission; Cadmium Sulphuratum in stomach cancer.
There is too some articles about rectal cancer treating with Cadmium (you can see at www.homeoint.org).

Best regards
Andrés
