Cancer Deaths – Declining Trend?

3,000 fewer cancer deaths:

Cancer deaths in the United States dropped for the second year in a row, health officials reported yesterday, confirming that the trend is real and becoming more pronounced, too.

The news was cause for celebration among doctors and politicians. “When we saw the first decline, the number wasn’t that enormous,” Dr. Felice Schnoll-Sussman, a cancer physician at New York-Presbyterian Hospital/Weill Cornell Medical Center said. “But once you start to see a trend like this, it obviously makes you feel like ‘We must be doing something right! ‘”

Is this really a trend? I have not examined the data at all but I seriously doubt it. People (the media even more so) constantly overreact to variation in data. Maybe I am wrong, certainly I should look at the data and see what it says – and I will if I get some time and remember. But I am more confident in my belief this is more overreaction to random variation than in the headlines. Why? Because so often when I do look more closely at the numbers my general observation of overreaction to random variation is confirmed while news reports talk of “trends.” Hopefully I am wrong this time.

Ok, I couldn’t resist and I did a little looking for some data. This is how crazy it is. The press release from the American Cancer Society states:

‘Virtually untreatable’ TB found

‘Virtually untreatable’ TB found:

TB presently causes about 1.7 million deaths a year worldwide, but researchers are worried about the emergence of strains that are resistant to drugs.

Drug resistance is caused by poor TB control, through taking the wrong types of drugs for the incorrect duration.

Multi-drug resistant TB (MDR TB), which describes strains of TB that are resistant to at least two of the main first-line TB drugs, is already a growing concern.

Globally, the WHO estimates there are about 425,000 cases of MDR TB a year, mostly occurring in the former Soviet Union, China and India.

Soil Could Shed Light on Antibiotic Resistance

Soil Could Shed Light on Antibiotic Resistance, Science Friday podcast (7 minutes) from NPR. The podcast is an interview with Gerry Wright, McMaster University, Canada.

“New research points to drug resistance in soil-dwelling bacteria. Scientists say studying bacteria in the soil can help in understanding how the bacteria in humans develop resistance.”
