Subject: Re: [cancercure] Photodynamic Therapy and Colored light Therapy
Hi List,
I am glad to see FDA has approved a light therapy for Cancer. It may be the same as the simple colored light therapy used in the United States from the 1920′s to around the 1940′s. When the FDA confiscated the machines and jailed its foremost user Dinshah Ghadiali after a very curious trial in which much of the evidence disappeared in a mysterious fire to his office. The approval of this therapy involving red light, one of the colors he used may be the same as his therapy described below. It may be different from the Photodynamic therapy approved, but it gives new credence to some of the applications–including cancer that are covered in the educational materials mentioned below.
I often overlook one of the most esoteric alternative therapies that has more advantages and applications than any other therapy I have encountered. It sounds too simple and too good to be effective but I have had good results when I have been stumped. Granted I have not used it that much, but it is definitely worth a closer look. It is colored light therapy. which sounds strange, but please look a little closer.
It is cheap, easy to administer and has a very wide application to almost every condition-just what the quackbusters warn you about. But they are just trying to keep you from trying it.
I am a runner and I used it to cure a heel spur about 8 years ago which had me hobbling around for 4 or 5 months. That sounds like it is a lot simpler than your more serious life threatening conditions-BUT. I have anecdotally heard tremendous things about it and it’s worth a good try in any event. It is the simplest to use.
A number of people have expressed an interest in use of another alternative therapy. I have found a very interesting treatment which was at one time used in the 1920′s to 1930′s in some major hospitals in the United States.
It is an ideal treatment for patients. It is cheap, easy to get and can be self administered. It is the use of colored filtered light, topically applied. The therapy works on the principal that different colored lights have different frequencies that effect the bodies tissues and organs. This Therapy sounds too simple but there have been some very good anecdotal reports.
The therapy was developed by .Dinshah Ghadiali, a mathematician early in this century-before there was an FDA to “protect us”. Ghadiali came to healing medicine with a very strong background in mathematics and the physical sciences. He had been a Professor of Mathematics and Physics in India used this knowledge to develop this treatment when he came to the US..
An article on the subject was published in the Atlantic Medical Journal of April 1927 by Dr.Kate Baldwin,MD former senior surgeon at Philadelphia Women’s Hospital.
Although the FDA confiscated all the machines used to administer the treatment, it is simple to reconstruct and use. Dinshah Ghadiali’s children have kept his ideas alive through the establishment of an educational foundation to promote his ideas. Since we still have a right to freedom of expression.
For $20.00 they will send you a Book “Let There Be Light” which outlines the process and the theory. It also shows that the battle for using cheap and effective therapies that threatened the economics of the medical practitioner monopoly has a long history. They also send you a video explaining the book.
Briefly the only materials you will need are a simple light source such as a simple flashlight and colored filters(Roscolene filters) similar to those used in theatrical presentations. If you can’t find them locally send to Rosco Laboratories 36 Bush Avenue, Port Chester,NY 10573 tel. # 914-937-1300
The book tells you what specific filters to use, how to get them if you need to.
For Information send to: Dinshah Health Society,PO Box 707,Malaga,NJ 08328,USA
NOTE: they also have the book in German and videos for European VCR’s.
The Treatment includes Cancer in general and specific cancers, e.g. adrenal,liver, stomach and leukemia. Epilepsy, Arthritis,Cardiac Conditions almost everything you can think of.

______________________________________________________ ________________ Overview
PDT is approved by the United States Food & Drug Administration (FDA) for the treatment of both early and late-stage lung cancer. Other countries have approved PDT for treatment of various cancers as well. Unlike chemotherapy, radiation, and surgery, PDT is useful in treating all cell types, whether small cell or non-small cell carcinoma. For further discussion of types of lung cancer, read this page.
You should know that this page is intended to give patients and others an introduction to PDT, not to replace advice and information from your health care provider. People who have cancer are encouraged to discuss all their treatment options with their physician and loved ones.
What’s so great about PDT?
One of the main advantages of PDT in lung cancer is that it works quickly. For example, a person with a tumor blocking a major airway may get relief in a few days. Another plus is that PDT can work in places where surgery would not be feasible, such as the trachea, the major airway leading from the voice box to the lungs. Here’s a drawing of the lungs that shows how PDT reaches a tumor partially blocking a bronchus. pdtlung_th.gif Click on the picture to enlarge.
The structures of the lung shown in the picture are:
* the alveoli: tiny sacs that take in oxygen
* the trachea: the main airway that leads from the throat to the bronchi
* the bronchi: the two major airways that lead from the trachea to the right and left lungs
* the bronchioles: smaller airways that lead from the bronchi to the alveoli
The drawing shows how a bronchoscope, a flexible tube inserted through the patient’s mouth, is directed into a bronchus. An optical fiber is threaded through the bronchoscope. When the laser is turned on, light shines from the end of the optical fiber on the tumor.
Another advantage is that PDT can be repeated a number of times, unlike radiation and chemotherapy. This feature allows physicians to repeatedly treat tumors and control their growth in cases where cure is not possible.
PDT has few side effects. The most common side effect is photosensitivity, or sensitivity to bright light. The period of photosensitivity varies from drug to drug. With the only
FDA-approved drug in the United States, Photofrin®, photosensitivity lasts 4-6 weeks. Patients must protect their skin from bright light during this period.
What’s the downside?
As with all medical treatments, there are limitations to what PDT can do. The tumor has to be located in a place where it can be accessed with the bronchoscope, the flexible tube inserted through the mouth and into the lungs to see the tumor and shine light on it.
Devices for implanting optical fibers to deliver laser light to tumors lying deep within the body are in development. However, regular clinical use of these devices is a few years away.
Red light is used for PDT because it penetrates more deeply into tissue than other colors or wavelengths. Still, the red laser light used for PDT can only go so deep before it is absorbed by the tissue or scattered too much to be therapeutic. PDT penetrates into tissue to a depth of about one-half to one centimeter (about 1/4 inch). Two or three laser light treatments are often needed to shine light on the deeper parts of a thick tumor.
Research is being done to find ways to increase the depth of penetration with new photosensitizing drugs and different wavelengths of light.
What are the side effects?
The major side effect of PDT is photosensitivity, or sensitivity to light. Most people find this inconvenient, but not intolerable. The photosensitizing drug currently used for PDT stays in the skin for about 4-6 weeks. During this time period, the patient must be careful not to get too much exposure to bright light, such as sunlight, or the bright overhead light in a dentist’s office. A gradual increase in bright light exposure neutralizes or “bleaches” the drug slowly, and photosensitivity diminishes. As this occurs, many people develop temporary skin darkening, much like having a suntan. If you are a PDT patient, be sure to ask your health care provider about photosensitivity.
Pain is another side effect of PDT. As the diseased tissue breaks down, it causes inflammation which can cause pain. Fortunately, the pain of PDT is usually mild to moderate and is easily controlled with a prescription painkiller.
A third side effect of PDT for lung cancer is shortness of breath. This occurs from fluid buildup in the lungs after PDT. It is also caused by the inflammation that occurs as diseased tissue (tumor) is broken down and removed from the body. Mild shortness of breath is expected, but if you have any concerns about feeling short of breath, please phone your health care provider promptly.
The good news about the side effects of PDT is that they are usually easily managed and temporary. There is no cumulative damage to organs or healthy tissues, as occurs with radiotherapy (radiation) or chemotherapy.
The Future of PDT
Investigations are underway for treating many different types of diseases in various parts of the body. Only time will tell how many uses medical science finds for PDT. New types of light delivery devices and new photosensitizing drugs will expand the usefulness of PDT in the future. Investigations are underway into using PDT to treat skin disease, brain tumors, gynecological cancers, and other conditions. This page contains links to many of these sites.
If you are interested in finding out more about PDT, contact us. We also encourage you to investigate clinical trials at the National Cancer Institute.

Still don’t see if it is appropriate for small cell lung cancer. Any thoughts?

Good Post! I’m familiar with the use in lung cancer with PhotoFrin, but not breast. Here is the NCI fact sheets
PHOTODYNAMIC THERAPY
Photodynamic therapy (also called PDT, photoradiation therapy, phototherapy, or photochemotherapy) is a treatment for some types of cancer. It is based on the discovery that certain chemicals known as photosensitizing agents can kill one-celled organisms when the organisms are exposed to a particular type of light. PDT destroys cancer cells through the use of a fixed-frequency laser light in combination with a photosensitizing agent.
In PDT, the photosensitizing agent is injected into the bloodstream and absorbed by cells all over the body. The agent remains in cancer cells for a longer time than it does in normal cells. When the treated cancer cells are exposed to laser light, the photosensitizing agent absorbs the light and produces an active form of oxygen that destroys the treated cancer cells. Light exposure must be timed carefully so that it occurs when most of the photosensitizing agent has left healthy cells but is still present in the cancer cells.
The laser light used in PDT can be directed through a fiber-optic (a very thin glass strand). The fiber-optic is placed close to the cancer to deliver the proper amount of light. The fiber-optic can be directed through a bronchoscope into the lungs for the treatment of lung cancer or through an endoscope into the esophagus for the treatment of esophageal cancer.
An advantage of PDT is that it causes minimal damage to healthy tissue. However, because the laser light currently in use cannot pass through more than about 3 centimeters of tissue (a little more than one and an eighth inch), PDT is mainly used to treat tumors on or just under the skin or on the lining of internal organs.
Photodynamic therapy makes the skin and eyes sensitive to light for 6 weeks or more after treatment. Patients are advised to avoid direct sunlight and bright indoor light for at least 6 weeks. If patients must go outdoors, they need to wear protective clothing, including sunglasses. Patients should talk with their doctor about what to do if the skin becomes blistered, red, or swollen. Other temporary side effects of PDT are related to the treatment of specific areas and can include coughing, trouble swallowing, abdominal pain, and painful breathing or shortness of breath.
In December 1995, the U.S. Food and Drug Administration (FDA) approved a photosensitizing agent called porfimer sodium, or Photofrin®, to relieve symptoms of esophageal cancer that is causing an obstruction and for esophageal cancer that cannot be satisfactorily treated with lasers alone. In January 1998, the FDA approved porfimer sodium for the treatment of early nonsmall cell lung cancer in patients for whom the usual treatments for lung cancer are not appropriate. The National Cancer Institute and other institutions are supporting clinical trials (research studies) to evaluate the use of photodynamic therapy for several types of cancer, including cancers of the bladder, brain, larynx, and oral cavity. Researchers are also looking at different laser types, photosensitizers that can be applied to the skin to treat superficial skin cancers, and new photosensitizing agents that may increase the effectiveness of PDT against cancers that are located further below the skin or inside an organ.

Hi,
here is a folow up on Photodynamic therapy in cancer therapy.
“Photodynamic therapy ……… resulted in complete response in all patients.”
“Photodynamic technique offers a minimal-invasive, outpatient treatment modality for recurrent breast cancer on the chest wall with few side effects, high patient’s satisfaction and with possible repetitive application.”

Chest wall recurrences are a frequent problem in patients treated by mastectomy for breast cancer.Photodynamic therapy (PDT) provides an alternative treatment modality using a photosensitizer and laser light to induce selective tumor necrosis. PDT was performed as compassionate use in 7 patients aged 57.6 years (+/-12.6 SD). A total of 89 metastatic skin nodes were treated in 11 PDT sessions. As photosensitizer was applied intravenously. Patients (n = 3) photosensitized with a drug dose of 0.10 mg/kg bodyweight were irradiated 48hr after drug application at a lightdose of 5 J/cm(2). Patients (n = 4) were illuminated by an optical dose of 10 J/cm(2) 96 hr after photosensitization with 0.15 mg/kg. Laser light at a wavelength of 652 nm was generated by a diode laser and applied by a front lens light diffuser using a fluence rate of 20–25 mW/cm(2). PDT using m-THPC resulted in complete response in all patients. Response to treatment did not differ when using the 2 different drugdose protocols. Healing time depended mainly on the size of the illumination field but not on the lightdose. Pain score usually raised 1 day after PDT and lasted at higher levels for about 10 days. Healing time usually ranged between 8–10 weeks. Photodynamic technique offers a minimal-invasive, outpatient treatment modality for recurrent breast cancer on the chest wall with few side effects, high patient’s satisfaction and with possible repetitive application.
