How Sono-Photo Dynamic Therapy Works

Cancer is a little bit like a runaway train — the train must be stopped to get the cargo out. Similarly, the first and most difficult step in treating cancer is stopping the cancer from spreading. Sono-Photo Dynamic Therapy is a Signature Therapy here at Hope4Cancer, and it’s designed to halt, and then reverse, the growth of cancer.

Why Sono-Photo Dynamic Therapy?

Sono-Photo Dynamic Therapy (SPDT) is a very effective therapy. Here at Hope4Cancer, in conjunction with our other therapies, we usually see a 20 – 35% reduction in tumor size within the first eight to 10 days of treatment. And after 15 months of SPDT, we may see a 70 – 85% reduction in blood flow to tumor areas.

As one of three pioneers worldwide who have developed this method, I have personally seen SPDT destroy cancer cells in a way that is non-invasive, non-toxic and with virtually no side effects. SPDT makes use of three components: a photo and/or sono-sensitive activator, a source of light and/or sound at the correct wavelengths, and a source of oxygenation.  

How Sono-Photo Dynamic Therapy Works

Sono-Photo Dynamic Therapy works at the molecular level. The process starts by ingesting a sensitizer agent that responds to light and sound stimulation. One of our sensitizer agents, SP-Activate, is taken orally, and allowed to absorb into the blood stream sublingually (under the tongue). The sensitizer absorbs preferentially into cancer cells.

Once absorbed, the patient is exposed to light and sound at the specific frequency and intensity that activates the sensitizer. This activates the sensitizer within the cancer cells, initiating a cascade of molecular reactions. Once activated, the agent passes this light energy to oxygen molecules splitting them into high energy free radical oxygen, energetic enough to destroy the cell it occupies.

Under my direction, Hope4Cancer Treatment Centers offers a highly comprehensive inpatient and take-home Sono-Photo Dynamic Therapy protocol. This is complemented by careful work to address the cause of the cancer, plus other treatments, holistic nutrition and a detoxification program. Using SPDT, I have even seen patients with advanced stages of cancer recover without side effects.

Innovations in Sono-Photo Dynamic Therapy

SPDT has been around since the 1800s. While the concept was very exciting, but limited by the toxicity of the sensitizer agents used in those initial decades. Not very selective for cancer cells, these agents were very toxic — essentially, forms of chemotherapy. In addition to that, many of the early sensitizers caused high levels of photosensitivity in patients, making it impossible for them to step outside.  But in the late 1990s, significant progress was made in the development of non-toxic agents. This improved the opportunity for SPDT to become a viable non-invasive, non-toxic cancer treatment.

Here at Hope4Cancer, we’re proud of our contributions to this therapy. We have led the efforts in making SPDT reach new levels of maturity and wide global acceptance as an effective and safe therapy. Our latest innovations in the SPDT arena include the introduction of new light devices and sensitizers that are further improving our ability to treat a variety of cancer effectively.

When utilized alongside treatments to address the cause of the cancer and a complete detoxification program, even patients with advanced cancers can heal without side effects. At Hope4Cancer, our team is here for you or your loved one, using treatments like Sono-Photo Dynamic Therapy to help you on the journey to recovery.

  1. It sounds like you would have to live near the clinic in order to receive the number of SPDT treatments needed to heal the cancer. If I were to come to the clinic for 2-3 weeks to receive my initial treatments, what happens next? Please let me know if you can continue this treatment elsewhere. Thank you.

    1. During their stay at the clinic, our patients are educated on how to continue their treatments once they return home. Most patients come back for a free return consultation about 3 months after discharge, but that is not required. Our After Care team works with patients to address outstanding questions that may arise once you return home.

        1. Dear Carol,
          Every treatment plan is different, but if Sono-Photo Dynamic Therapy is in your prescribed protocol, you will be returning home either with an ultrasound device on LED light device depending on the nature of your cancer – that is included in your program costs.

    2. What is your experience with anal channel cancer? I had 30 radiation treatments that did nothing. I refused chemo. They would not operate. Had pet scan last week now they want to do a biopsy of liver and say there are suspicious markers there. I am 78 years old and enjoyed excellent health for 76 of them; no hospitalizations, no medications, felt great until I got constipated about 1 1/2 years ago. dr kept telling me month after month to eat more fiber, exercise, drink water, until I started bleeding then sent me to a surgeon for exam and 3 weeks later I got a colonoscopy and cancer confirmed.

    1. Hi Barbara,
      We get many patients with head and neck cancers that begin in glandular/lymphatic tissues. Treating these cancers with conventional methods is very challenging because they require systemic therapies that can prove highly toxic to the body. However, non-toxic therapeutic methods provide systemic benefit while not adding to the body’s toxic burden. I would strongly recommend that you speak with one of our patient counselors who can help you understand your options better.

      I have forwarded them your email address, so you may hear from them soon. However, for fastest service, please click here to self-schedule a call.

    1. Hi Ian,
      Yes. In fact, the overwhelming number of glioblastoma cases that we receive are post-chemo and post-radiation therapy. One of our recent cases, Aaron, has been 21 months free of any new cancer growth, raising clear hopes that the cancer may indeed have died from within. Our treatments are non-aggressive, non-toxic. We have several treatments that are known to cross the blood-brain barrier as well. I would strongly recommend that you contact one of our patient counselors for a free consultation (I will forward your email to them) so that they can evaluate your situation and make recommendations. If you would like to schedule a call, click here.

  2. Hi

    How about Acute Lymphobastic Leukemia in an adult prson. Can you treat that and is it a high success rate. The patient has under control now, but because of the toxic drug oills. But I want her to use natrual non toxic to treat and /or kill this leukemia.

    I am thinking of taking her to your clinic as I like the treatment options. Thank you.

  3. I was recently diagnosed with AITL and am investigating all my treatment options. I have not begun treatment of any type yet. What is your experience treating angioimmunoblastic T cell lymphoma successfully?

    1. Dear Stephanie,
      I am glad you are taking proactive action towards your healing. At Hope4Cancer, we treat all kinds of cancers including AITL. Most patients ask us if we have therapies that specifically target their type of cancer cells, but if that approach healed cancer, then chemotherapy and radiation would have been sufficient. The reality is that cancer is a systemic disease that must be healed system-wide through a true understanding of what influences cancer to form. We have worked hard to have available some of the best non-toxic cancer therapies in the world including Sono-Photo Dynamic Therapy, Sunivera Immunotherapy, Rigvir Virotherapy and others – many of which may be applicable in your case. These therapies would be integrated with our overall holistic program that roots out the deep causes that trigger cancer in the first place.

      Please discuss your specific case with one of our patient counselors. I have forwarded your email address to them, but in order to expedite, please request a free consultation by clicking the following link : schedule your free consultation. They will be happy to walk you through your options and recommend a treatment plan.

    1. Dear Helen,
      I would like you to first know that there is always hope. We have seen people rewind out from seemingly impossible situations. But most of those reversals that we have seen have been a result of an adherence to a strong, holistic protocol that includes non-toxic cancer therapies. I would strongly recommend that you reach out to one of our patient counselors by clicking here: schedule a free consultation.
