cancer of the prostate
"Numerous media reports followed a federal task force's announcement this month that there is insufficient medical evidence to assess the risks and benefits of prostate cancer screening in men younger than 75 and that doctors should stop testing men over age 75.
It's important to note that consideration was not given to the overwhelming body of emerging evidence that screening with PSA tests and digital rectal exams saves lives. Rates of death from prostate cancer and rates of diagnosis at advanced stages have decreased markedly since testing became widespread.
As a physician and a researcher specializing in prostate cancer, I worry that this recommendation will result in delays in potentially lifesaving treatment and possibly the unnecessary loss of life.
The U.S. Preventive Services Task Force did not even recommend screening for men at higher risk because of race or family history. The task force reasoned that screening might harm more men than it helps and that in men over 75 there was moderate certainty that the harm outweighs the benefits.
Physicians and patients who are concerned about preventing prostate cancer deaths choose to screen with prostate-specific antigen (PSA) tests because an inconclusive but increasingly compelling body of evidence shows that the screening reduces suffering and death from prostate cancer — the second-leading cause of cancer death among men in the United States."

In an Aug. 26 story about a new TV ad linking hot dogs with cancer, The Associated Press, relying on figures provided by a nutrition adviser to the American Institute for Cancer Research, erroneously reported average risks for colon cancer and how eating hot dogs affects those risks. Karen Collins said she misstated the average adult's lifetime risk for getting colorectal cancer, which is about 5 percent, not 5.8 percent.
She said she also miscalculated population-level risks of eating one hot dog a day for several years. That would increase the number of Americans who get colorectal cancer each year from 50 per 100,000 to 60 per 100,000 people — not from 58 per 100,000 to 70 per 100,000, as she had stated.
She said the level of risk is smaller for eating a hot dog once or twice a month but that it can't be precisely quantified. It would not mean up to a 1.4 percent increase in colon cancer risk, as she had indicated.

What makes pancreatic cancer so deadly?: Scientific American
"Gene Upshaw, the executive director of the National Football League Player's Association—the union for NFL players—died late Wednesday evening of pancreatic cancer while vacationing in California's Lake Tahoe. Doctors diagnosed the 63-year-old Hall of Fame offensive lineman with the disease just four days earlier.
Upshaw was a guard for the Oakland Raiders from 1967 to 1981. He played in seven Pro Bowls and three Super Bowls. He served as head of the NFL player's union for 25 years.
According to Bloomberg News, Upshaw's wife, Terri, took him to a hospital on Sunday, August 17th, because he was having trouble breathing. A biopsy revealed, much to everyone's surprise, that he had advanced pancreatic cancer.
In March, actor Patrick Swayze—star of the hit 1980s film Dirty Dancing—revealed he had been diagnosed with the illness in January. Doctors' reports indicated they had caught his cancer relatively early.
The pancreas secretes hormones and enzymes to digest our fats. One of those hormones is insulin, which prompts the body to use sugar in the blood rather than fat as energy. Its levels are low in diabetic patients, who suffer from abnormally high blood sugar."

Happiness may protect against cancer
"YOUNG women exposed to tragic events may be at a higher risk of breast cancer and being optimistic can help protect against the disease, a study has found.
A team of researchers say they may have found a link between a women’s outlook on life and the risk of breast cancer.
After questioning more than 600 women – include 255 breast cancer patients – about life experiences, happiness and depression, researchers found optimists were 25 per cent less likely to develop the disease.
Women who suffered two or more traumatic events in their life, such as losing a loved one, had a 62 per cent greater risk of being diagnosed with breast cancer, the research said.
“Young women who were exposed to a number of life events, should be considered as a risk group for breast cancer and treated accordingly,” the researchers said.
“We can carefully say that experiencing more than one meaningful life event is a risk factor for breast cancer among young women. "

starbucks a savior
"When Howard D. Schultz in 1985 founded the company that would become the wildly successful Starbucks chain, no financial adviser had to tell him that coffee was America’s leading beverage and caffeine its most widely used drug. The millions of customers who flock to Starbucks to order a double espresso, latte or coffee grande attest daily to his assessment of American passions."

Prostate cancer screening not recommended for men over 75_English_Xinhua
Prostate cancer screening not recommended for men over 75_English_Xinhua: "The U.S. Preventive Services Task Force has recommended that men over 75 should stop the routine prostate cancer screening since the risks involved pose more immediate danger than the cancer itself, according to media reports Wednesday.
The task force said that screening can detect some cases of prostate cancer, but the benefits of treatment in men over 75 'are small to none, because the treatment often causes 'moderate-to-substantial harms,' without evidence it saves the lives of these elderly men.
The panel did not recommend for or against prostate screening of men under 75 but suggested that doctors discuss the potential benefits and harms of the test with their patients.
'We carefully reviewed the available evidence to measure the benefits and harms of screening for prostate cancer and could not find adequate proof that early detection leads to fewer men dying of the disease,' said task force chairman Ned Calonge."
