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.

Now in a world piled high with smartphones,tablets and e-readers,technology has entered the classroom in ways unimaginable. Taking classes can be fun too. A11 you have to do is swipe your fingers on your phone screen and download same Apps, which can make your study more fun and efficient. Balancing study and play in a college setting has never been easy----and with the following few apps, it'll be tough to tell the two apart.
Evernote
Use: note-taking
Can be used on:Phone/iPad/iPod touch,Android,BlackBerry,PalmOS and Windows Phone 7
Price:free
It's hard to imagine that with all the magical gadgets (新发明), the eager, studious types would still take out a notepad,pencil,and highlighter-and take notes in class. While it's not an actual planner or calendar App,if you take notes to stay organized,then Evermote is for you. The main thing about Evernate is that all of your notes are automatically sent into the cloud(云储存平台上)---and then you can access them from any web-connected computer via the Evermote App or a web browser. Evermote also support audio and photo notes-rather handy if you want to record your lecture or take photos of any projected notes. But,of course, ask for permission first.
Wikipanion
Use:research database
Can be used on:iPhone/Pad/iPod touch
Price:free(Wikipanion Plus for$4, 99,or 31.87 yuan)
Now,you don't necessarily have to go to a library or anywhere with computer services to do research work for your paper anymore. You can get access to the research databases just on your smartphone or tablet. Wikipanion gives you a simplified version of Wikipedia without leaving out any of the site's extra features. The normal links that you'd see to each section of an article no longer on the main screen. Instead,there's a small icon(图示影像) located at the bottom of the app,which can be used to access all the sections of an article. You can also open the links in Safari(苹果)Safari(浏览器).According to the developers' site, loading Wikipedia pages with Wikipanion is a lot faster than accessing the Wikipedia site from the iPhone's browses(浏览器). To be honest,we agree.
