Cancer places extraordinary demands on the body. Beyond the disease itself, chemotherapy and radiation place stress on immune function, metabolism, mitochondrial energy production, inflammation, and the body’s ability to recover between treatments. How the body functions at the cellular and metabolic level during this time matters.
At Castro Integrative Medicine, we work with cancer patients who want integrative care that actively supports their body during cancer treatment and recovery - care that addresses oxygen use, oxidative stress, immune signaling, and cellular energy.
Many patients come to us for two integrative therapies that address the foundational drivers of cancer biology.
🔷 High-Dose Vitamin C IV Therapy
When vitamin C is given intravenously at very high doses, it behaves differently than oral vitamin C. At these levels, it creates an oxidative effect that targets known vulnerabilities in cancer cells, particularly their abnormal metabolism and limited ability to manage high oxidative pressure. This allows high-dose vitamin C IV to directly damage cancer cells and contribute to their breakdown. This same oxidative pathway is central to how chemotherapy and radiation work, which is why high-dose vitamin C IV is used in integrative oncology to complement conventional cancer treatment.
🔷Ozone IV Therapy
Ozone IV Therapy increases oxygen availability and delivers controlled oxidative stress at the cellular level. Cancer cells depend on low-oxygen, abnormal metabolic conditions to survive. By improving oxygen utilization and applying controlled oxidative stress, ozone therapy directly damages cancer cells and disrupts the conditions they need to survive, while supporting circulation, immune communication, and overall cellular function in healthy tissue.
Many patients use both IV therapies because they want to support treatment, recovery, and the body’s internal balance at the same time.
This approach is not about replacing oncology care.
It is about changing the internal terrain and supporting the body at the cellular level while conventional treatment is underway.
