Community Projects
Our comunity projects involve outreach to veterinary and clinical centers by providing equipment and training on Radio Frequency (RF) heating in the treatment of cancer. Hyperthermia is primarily used as an adjuvant therapy to boost the effects of conventional cancer treatment like radiation, chemotherapy and surgery.
- Veterinary outreach at the Mobile Vet Connection clinic in Orangevale

Patient undergoing RF hyperthermia for bone cancer
- Clinical outreach at the Sacramento Naturopathic Clinical Center

Patient undergoing RF hyperthermia for Head and Neck cancer
Recent Grants
