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.
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 previous personal experience with the disease, should continue to get screened regularly. But for the rest, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy.
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.
It’s not an easy calculation to make, but one that makes sense for patients. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves from medical disputes. We need to think about the wise use of health care, which 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.”

Based on new analysis, we are rapidly approaching major climate change and the effects on society and the environment could be quite severe. Geographers predict that within the next eighty years, current world climate zones could shift and some could completely disappear. Polar regions will get colder while tropical regions will get even hotter, forcing animals to migrate (迁徙) north.
Climate changes like these could lead to the spread of diseases. Tropical storms and hurricanes will not only increase but may also become more intense. If the changes come too quickly, animal and plant species may not be able to adapt fast enough and could disappear.
According to Science Daily, a new study predicts that by the year 2100, many of today’s familiar climates will be replaced by climates unknown in today’s world. It is urgent that we reduce the risks of these far-reaching consequences for the whole world. The planet itself has been showing signs of change. In 2004, a serious tsunami created by a major earthquake killed thousands in Sumatra and in 2008, thousands died in China because of another severe earthquake. Egypt was hit in 2009 with a major earthquake and Haiti was devastated in 2010 by yet another massive earthquake.
Within just the last few months, new reports from around the world have been coming in and most agree that our climate situation is much worse than previously thought. At this point, it doesn’t matter what is causing it, but rather, what can be done about it. What’s more, our world is getting more and more unstable every year. There is war and threat of war everywhere. Natural disasters are becoming more frequent and serious.
However, other planets are experiencing global warming as well as our own and some scientists believe there may be some connection between this. No one knows anything for sure at this point because there is simply not enough data.
