My Malignant Melanoma

Another poster on What Now has passed on the irresponsible claims of a "Dr" Lodi about chemotherapy.

Legal threats on behalf of Lodi prevent me from commenting further than to say that Mr Lodi is presumably seeking only to promote the oxidative, chelation, homoeopathic, and other quack therapies he offers at his private clinic by his attacks on proven conventional treatments. His motivation is therefore financial.

His profoundly unhelpful and scientifically unjustified claims that doctors would not themselves have the treatments they give to patients were published in "Get Fresh" magazine.

This publication looks like a harmless health and beauty mag, but seems to actually be a slick propaganda sheet pushing the raw food quack diet, and seemingly all other forms of dietary alternative medicine.

This is not a reliable source of scientific or medical information. I wouldn't even trust its beauty tips.

They have been reported to their local trading standards department and the The Medicines and Healthcare products Regulatory Agency for what appears to be a clear breach of the Cancer Act, which prohibits anyone from making claims to be able to heal cancer of the sort they do on their website.

"Dr" Lodi is out of reach in the US, but these muppets are in the UK, and bound by our laws.

There is no alternative therapy which can strengthen the immune system. I'm sorry that anyone has been given false hope, or distressed by the false claims of a quack and a worthless magazine, but that's the truth.

Don't believe me? Ask Paul Merton's wife. Oh that's right, you can't, because she tried to beat cancer with the power of nutrition and positive thinking, and is consequently dead.

I think Gary38 is being a little too kind in describing this as "unproven" on the WN site, when "total and complete bollocks" might be more accurate, but sometimes it's hard to know which description is more convincing to the audience.

I see someone is promoting a dietary supplement called Biovitali Vitalcells on the What Now board with what looks to the unsophisticated eye like some reasonable scientific evidence. I guess the moderators will eventually get round to deleting this, but wouldn't it be better to have a look at how strong the evidence is?

So let's have a look at that evidence, which is:

1. The product has apparently been patented

2. It is supposedly endorsed by the MD Anderson Cancer Research Centre and the National Foundation for Cancer Research

3. Laboratory trials show it not just to stop cancer and cardiovascular illnesses in their tracks, but to prevent them occurring in the first place, and to extend life by 30%

Taking these claims one by one-

1. Patenting something does not mean that anyone has shown it to actually work. It is a commercial device to prevent anyone copying your work. Having a patent does not mean that something does what it claims. This is no evidence at all.

2. It seems not to be endorsed by either the MD Anderson Cancer Research Centre, or the National Foundation for Cancer Research as is claimed in the manufacturers literature. Both of the organisations in fact have advice against cancer patients and others taking non-prescribed food supplements on their websites, here and here. Neither of their websites make any mention of this product.

3. If the non-peer-reviewed in-house research on the manufacturer's website were true, and applicable to humans, cancer would be no more serious than the common cold. Every single one of the ingredients shows at least 80% tumour inhibition, and together they are even more powerful. But every one of these ingredients is a substance present in normal foodstuffs. How can this be?

Let's see what might be going on. Have a look at the table at the end on lifespan increase. 100% of these mice get cancer during their lives. That is because this strain of mouse has been specially bred to get skin cancer.

The experimenters made getting cancer a racing certainty in their antioxidant experiments by also injecting the mice with a powerful cancer-causing agent, and then constantly feeding them with something which helps cancer to grow.

They have not published their experimental protocol, but let us generously assume it was similar to that used in this real scientific research, despite us not being in a position to check whether they did things properly.

They fed the supplements along with the substance which helps cancer to grow, so that exposure to the promoter and the antioxidants was simultaneous.

Every single one of the ingredients showed incredible levels of tumour inhibition, far higher than that shown by the real treatment linked to previously. If I were a mouse genetically engineered to get a type of skin cancer who happened to have accidentally been injected with a potent carcinogen, and to be unfortunate enough to be on a drip of a drug which promoted the growth of cancer, it seems like this product would be well worth a look. Any other species, any other sort of cancer? Well, we'd have to look at the peer reviewed evidence.

Of course, this product is just a vitamin and antioxidant supplement, which contains the usual stuff, including a number of substances that in real people have been shown promote cancer when taken as a supplement, rather than inhibiting it, such as:

Beta Carotene
Vitamin A
Vitamin E
Vitamin C

Furthermore, the claims that taking combinations of these substances improved their effect is the opposite of what has been found in real studies. Combining beta carotene with vitamin A or vitamin E actually kills more people than either ingredient alone. Source.

There is therefore no chance whatever that the lab results shown in its website have any meaning for cancer patients.

Cancer Research UK advise as follows about all food supplements:

" We need a lot more research in this area before we will know for sure which vitamin and diet supplements may play a role in helping treat, prevent or control cancer. The best way to get the vitamins and minerals you need is through a balanced and varied diet, with plenty of fruit and vegetables. Vitamin supplements don’t have the same benefits as naturally occurring vitamins in fruit and vegetables."

And of course we now know that for those receiving active treatment, antioxidants and vitamin C can block the effects of chemotherapy and radiotherapy. Source.

Someone has suggested on the What Now site that explaining all of the above is unnecessary, and that the last thing the site needs are know-alls telling you all what to think. But here is that same person thanking me for educating them on this very subject after they gave bad advice to someone.

Maybe the site doesn't need know-alls, but know-somethings are useful in situations like this, aren't they? Failing that, the know-nothings could at least not give advice to desperate people in areas they know nothing about.

I see someone has started a new "natural treatment" thread on WN. I'll be interested to see if Gary's polite and sound advice is well-taken. History suggests no, but the site is under moderator lockdown whilst my complaint is being investigated, so who knows?

I have recently had a book called "Anticancer-a new way of life" by a French psychiatrist brought to my attention.

Whilst the author makes many helpful (if obvious) suggestions in line with scientific knowledge, he mixes in with them liberal quantities of reasonable-sounding nonsense.

Of course as a head-shrinker he is no more qualified than a member of the public to write a book on cancer prevention or cure. He makes this obvious in being taken in by alternative medicine propaganda which a "real" doctor would presumably have spotted.

Particularly insidious is the idea that things which might be associated with reducing the risk of occurence of cancer might also affect the course of disease once you have it. This does not follow.

So let's have a look at a few of the claims he makes:

1. Sugar feeds cancer preferentially

Whilst this may sound plausible, it is unsupported by any scrap of scientific evidence. Source

2. Stress feeds cancer

Whilst plausible for many years, recent detailed research shows this to be false. Source

3. "Environmental toxins" feed cancer

In the sense used in the book, this is without scientific basis, and is actually informed by alternative medicine propaganda- here is a helpful article about this area of misinformation.

4. Genetics do not have an effect on cancer

This is possibly the most ridiculous assertion in the book. Some cancers are solely genetic in origin, most occur as an interplay of genetic and environmental factors. Source

5. Psychological wounds/Hopelessness/Mental attitude feeds cancer

There is no scientific evidence to support this assertion, though it is sometimes held by medical professionals on the basis of their own partial recollection of cases.

The latest study showed no association between mental attitude and progression of cancer.

6. There are anticancer foods:

There are associations between eating certain foods and increased/decreased risk of getting certain cancers (not all cancers, note). Source

There are however no known associations between eating certain foods and survival once you already have cancer.

He recommends a number of specific foods:

a. Turmeric

Turmeric does indeed show some interesting effects. Unfortunately the dose required to obtain them in a human being is 110g per day of turmeric powder! Source

b. GreenTea

A recent study of 26,000 Japanese has shown there to be no beneficial effect on stomach cancer from green tea. Another recent Japanese study of 41,400 people showed no protection against lung cancer.

Note that this means that the previous lab scale work which showed promise for green tea is meaningless.

c. Berries

Bilberries have shown some promise in the lab against cancer cells. Source

However, any suggestion that they have an effect on existing cancer in the human body is highly premature.

d. Cabbage family vegetables

There is limited evidence for this, but strangely, the research only provides evidence for a possible protective effect in men. Source

e. Onion family vegetables

It has not been demonstrated to usual scientific standards that these vegetables reduce the risk of cancer.

There is no evidence to support the idea that they affect the progress of existing cancer.

There is however some evidence to support the assertion that consumption of these vegetables is associated with lower levels of cancer, at least in Europe. Source

The evidence for any role for garlic in cancer prevention is weak. Source

8. You can deliberately and helpfully stimulate your own immune system to prevent and eliminate cancer

There is no evidence for this whatever, and it is a cornerstone of a number of brands of quackery. Source

9. Organic food is better for you

There is no evidence for this whatever. Source

10. Meat causes cancer

There is sufficient evidence to associate red meat with bowel cancer. There is no evidence to suggest that any other link exists between meat and cancer. Source

Of course, it is not for me or anyone else anyone else to prove the author wrong. In science, it is his job to prove his ideas right. He has failed to do so.

He has not really even tried, but has just cherry-picked some attractive ideas with little supporting evidence, and lashed them together into a crock of poor quality pop medicine. A crock of something, certainly.
