Too Much Health

There is a fascinating and timely report about Hormone Replacement Therapy in the Guardian today.

Survey after survey has linked hormone replacement therapy to cancer, strokes, blood clots and heart disease. Why, then, are so many women so relaxed about using it? And why do some doctors insist that the dangers are exaggerated? Sarah Boseley investigates

What it reveals is the continued attraction of HRT, more than a million women continue to take it in the UK, although for some of those women its pretty clear that taking HRT is not the optimum intervention.

What I find interesting about this is how compelling medical solutions can appear and how enduring they can be once the public first accepts them to be true. Once an idea like HRT has been promoted in the public realm, and once there is promotion of various sorts floating around, then its very difficult to get the idea our of the public imagination. None of us seem very attracted to the idea that actually medical intervention is bad for you.

I think many of us are afflicted by it. We go to doctors because we think they can help us. And they sometimes fob us off with placebos or what they think is more or less harmless sorts of drugs and interventions, such as HRT.

Its linked to my favourite piece of commentary of the year. Published on January 2nd, some of the best analysts in the business simply state,

For most Americans, the biggest health threat is not avian flu, West Nile or mad cow disease. It’s our health-care system. You might think this is because doctors make mistakes (we do make mistakes). But you can’t be a victim of medical error if you are not in the system. The larger threat posed by American medicine is that more and more of us are being drawn into the system not because of an epidemic of disease, but because of an epidemic of diagnoses.

Although this is a particularly American problem, UK patients are also afflicted. We demand and demand and demand in some situations where doing nothing might be the right thing to do.

CANCER DEATHS DECLINING

The number of cancer deaths in the United States has dropped for the second year in a row, the American Cancer Society reported yesterday. The finding suggests that the small drop reported last year — the first in more than 70 years — was real, possibly the start of a continuing decrease and not merely a statistical fluke, researchers said.

The American Cancer Society's annual study of cancer mortality came out yesterday. And for the second year its great news.

The New York Times, though, has a tinge of pessimism in its second paragraph.
"Although the drop is notable, it still pales in comparison with the number of cancer deaths, 553,888 in 2004.....But it has taken enormous efforts and ingenuity to produce relatively small gains." And there is a graph attached to the piece which makes out that cancer mortality has rising from about 400,000 deaths in the US to about 550,000 since 1980.

Well. Although its right to be cautious, these figures should be cause for enormous cheer particularly because cancer mortality is not an isolated statistic. Since the 1980s, the rates of heart disease have declined by about 25 per cent since the mid 1980s. As the leading cause of death in the US is clattering down, people are dying of other things. And although cancer has been slow to catch up with cardiovascular treatments, it is catching up.

And more than anything this kind of statistic rebutts the widely held belief that cancer rates are increasing.

ONE IN FOUR PEOPLE SAY CANCER IS DOWN TO FATE

Cancer Research UK did this amazing piece of research, and they discovered that one in four people think that cancer has nothing to do with risk factors and is only down to fate.

It is amazing, after half a century of campaigning about smoking, and twenty five years about the sun, and a least a few decades about five fruit and veg a dag, how little the message gets through. In poorer areas, that number reaches almost half of the population believes its fate.

I think one of the reasons is the complete mumbo jumbo that is so often spoken about the disease. Yesterday a faith healer (admittedly quite a comic one) was on BBC2 explaining that cancer is all about emotions, and Sense About Science recently wrote about the rubbish that celebrities speak about science.

And this really affects people's lives.

It really is time to change how we think about cancer.

BREAST CANCER INCIDENCE DROP

The sharp drop in breast cancer rates in the United States reported last week is astonishingly good news. It is the first major reduction in the incidence of a malignancy that strikes more than 200,000 American women every year — and kills some 40,000 annually.

This is extraordinary news. For the first time incidence in breast cancer is declining massively, by 7 per cent. It seems likely that is linked to the declining use of hormone replacement therapy. Which all goes to show that if we can understand the causes, then we can begin to tackle this disease.

Red Meat and Breast Cancer

More bad news for red meat eaters. Not only is it bad for cancers of the gut, but it also seems to increase breast cancer risk.

Women who eat red meat every day are almost twice as likely to develop certain types of breast cancer, a long-term study published today has found.

Scientists who monitored 90,000 women for more than a decade found that those who ate a high meat diet were much more prone to developing the hormonally reactive breast cancers, which account for more than half of all breast cancers.

The scientists suggest that synthetic hormones used in meat production could be behind the trend.

The message is getting clearer and clearer.

PSA test - PROSTATE SPECIFIC ANTIGEN

My Dad always had a low PSA score. It meant doctors never thought he had a life threatening illness. At last there seems to be some hope that the PSA test is being refined.

A Lung Cancer Breakthrough? - annual CT scanning

My contention is that it is rare to see in the newspapers a proper cautious approach to the dilemmas of prevention. Truth is, that the balancing of risks and benefits doesn't make that great storytelling, its too equivocal, and its too cautious for great journalism. But these careful judgements are the truth. I talk about one such story in a latter chapter in my book.

But here is a rare example. The good old New York Times in an editorial about a new lung cancer study.

Some cancer experts and advocates for lung cancer patients are hailing the dawn of a new era in which lung cancer will move from a disease that is usually fatal to one that is usually curable. So why do many experts have misgivings about recommending widespread CT scan screening?

For once it seems that the newspaper is offering the proper analyis, whilst the New England Journal of Medicine is offering a much less rigorous view.

Conclusions Annual spiral CT screening can detect lung cancer that is curable.

BREAST CANCER SCREENING

Today there is much hoopla about a new report from the nordic cochrane collaboration. The Press Association tells us that "thousands of women in England could be undergoing unnecessary and potentially devastating treatment for suspected breast cancer".

A vaccine, at last

Late in September 1970, many in the US cancer establishment were promising that a vaccine for cancer was imminent. They thought they had found virus particles in a whole variety of cancers. They thought that cancer would succumb to human endeavour just as Polio had a decade or so before.

In the end, cancer turned out to be a more intractable problem. Yet there was one cancer were a virus was pretty clearly the cause. That was cervival cancer.

In the 36 years since the virus cancer fad of the early 1970s, much has been done. And finally last week, the US FDA announced that it had licensed a vaccine for cervical cancer. What a result?

Our strange ideas about drugs

So at last the National Centre for Clinical Excellence has recommended that a new class of breast cancer drugs be allowed on the NHS. This news has taken a long time in coming. There has been some clinical trials that have shown the benefits of these newer and more expensive drugs for years.

What I find interesting is how aromatase inhibitors have been treated differently to Herceptin. The latter was hailed as a wonder drug. Tens of patients have been campaigning for their 'life-saving' drug. There has been a massive media campaign.

Yet arguably, aromotase inhibitors will save many more lives. The Daily Mail said they'd save 1000 lives a year in the UK. Of course, unlike Herceptin they are not based on the wonders of genetic manipulation. And they are only an improvement of an existing sort of drug - Tamoxifen has been working in a roughly similar way for twenty years. And as a consequence, they have sort of given a lower priority.

Its little wonder that patients find it so difficult to navigate the treatment choices - when the coverage in the newspapers is so lopsided.
