A US group have published a paper on an evaluation of six different acupuncture treatment regimens for osteosarcoma tumor growth in an animal model. Results showed that certain points and regimens had positive effects on tumor growth and metastasis but that others had a negative effect. Electro acupuncture applied twice weekly to ST-36 gave the most positive results.
