Cancer Patients Can Be Endangered By `Alternative Cures` On The Web

21.08.2002

Internet websites promoting `alternative` cures for cancer can seriously harm patients who follow their advice . And some are downright dangerous – according to an editorial published today in the British Journal of Cancer.

A survey of 13 sites relating to alternative or complementary medicine and cancer found that patients were not only discouraged from using conventional cancer therapies but were not informed about alternative remedies that have been shown to be ineffective.

The warning is sounded by scientists at Exeter University`s Department of Complementary Medicine*.

Professor Edzard Ernst, who headed research into the subject, says most sites visited recommended a multitude of treatments with little consensus between them.

"Cancer patients get confused in the maze of claims and counter claims and often turn to the Internet for information which can give advice that has led to real harm and even death in some cases. "

The study defined five sites as potentially harmful to patients who followed their advice. And two sites, www.alternativemedicine.com and www.heall.com were described as "dangerous" to cancer patients.

Researcher Katja Schmidt says that www.alternativemedicine.com downgraded conventional cancer treatments by statements such as `women with breast cancer are likely to die faster with chemotherapy than without` and that `of approximately half a million people who die of cancer each year only about two to three per cent actually gain benefit from chemotherapy. `

She says: "The site lists treatments such as herbal remedies and shark cartilage as offering `promise as cancer treatment.` With a statement like that a patient might abandon orthodox cancer treatment on the basis of the arguments on this website. Also the site has no mention of a governing body nor a reference to frequency of updates. It offers products for sale and is supported by advertising."

The site www.heall.com provides no details of research efforts for the therapies it promotes nor does it request a patient should also seek conventional advice. "It claims that alternative therapies being used to treat and/or cure cancer are botanicals such as goldenseal, pokeroot, wild indigo, thuja, figwort, red clover, Essiac and astragalus. But there is no evidence that any of these herbal medicines cure cancer," says Schmidt.

When people are diagnosed with cancer they are in shock and feel a real sense of crisis. " They think:` What else can we do?` " says Prof Ernst. "They read pages of information on websites and read that shark cartilage promises a cure for cancer. Patients are overloaded with information and it is very difficult for them to assess the credibility of information they find on random websites.

" As long as statements on the web don`t promise a cure but simply offer a chance to improve the quality of a cancer patient`s life – that is quite a different matter. If a person feels better after massage or reflexology or aromatherapy that is a good thing – as long as the patient is aware that this is not a cure."

By contrast the researchers praised Cancer Research UK`s award-winning website designed specifically for patients by a team of medical experts. Called www.cancerhelp.org.uk this site "is a very useful source of information regarding conventional cancer treatments," says Schmidt. v "Complementary cancer treatments are also discussed. There are details of research given for various therapies and the site provides references to sources of information, links to other cancer websites and is frequently updated. It provides non-profit primary information."

Chief executive of Cancer Research UK Sir Paul Nurse says: " Cancer Research UK works with scientists involved in looking at complementary medicine which, as the name suggests, can complement orthodox treatment and bring benefits to the patient. There is a confusing amount of information about cancer treatment and so called `alternative` cancer cures available on the Internet. Many of these have no clinical or scientific basis and so it is vitally important that patients seek advice from their doctors before embarking on any alternative therapy. Our Cancer Help website only offers patients information that has been extensively checked by a wide variety of specialists with experience of treating the disease."

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
