Cancer-killing X-rays,nuclear threat detection and a new typ

Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors — or doesn’t it?
　　While such vigilant(警觉的)tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it’s important to weigh the health benefits of screening against the risks and costs of routine testing.
　　In many cases, screening can lead to additional biopsies and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups.
　　It’s hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy(预期寿命).
　　A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening- especially considering the explosion of the elderly that will soon swell our population.
　　It’s not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing of health care.”
　　That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.

Our risk of cancer rises rapidly as we age. So it makes sense that the elderly should be routinely screened for new tumors (肿瘤) or doesn’t it?
While such tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it s important to weigh the health benefits of screening against the risks and costs of routine testing.
In many cases, screening can lead to additional examinations and operations to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not cause serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained (根深蒂固的) that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a noisy reaction among doctors, patients and social groups.

When I was struggling with cancer a few years ago, my wife and I formed our own “couple caution circle”. Anytime a doctor came with news of my progress, my wife would give me a big hug. The reports were seldom good during the early stages of my illness, and one day a doctor brought particularly frightening news. Staring at my reports, he said in a low voice, “It doesn’t look like you’re going to make it.”
Before I could ask him a question, my wife stood up, handed me my clothes, adjusted the tubes fastened to my body and said, “Let’s get out of here. This man is a risk to your health. ” As she helped me struggle to the door, the doctor came near us. “Stay back,” demanded my wife. “Stay away from us.”
As we walked together down the hall, the doctor attempted to catch up with us “Keep going,” said my wife, pushing the intravenous（静脉注射的）stand. “We’re going to talk to someone who really knows what is going on.” Then she held up her hand to the doctor. “Don’t come any closer to us.”
The two of us moved as one. We escaped to the safety and hoped of a doctor who did not confuse diagnosis with conclusion. I could never have made that walk toward wellness alone.
