The Dilemma of Breast Cancer Screening

By : Kevin Pho
The American College of Obstetricians and Gynecologists (ACOG) recently released their recommendations for breast cancer screening.
Previously, they had recommended a mammogram every 1 to 2 years for women between the ages of 40 to 49.
Now, they recommend more intensive screening:
Due to the high incidence of breast cancer in the US and the potential to reduce deaths from it when caught early, The American College of Obstetricians and Gynecologists (The College) today issued new breast cancer screening guidelines that recommend mammography screening be offered annually to women beginning at age 40. Previous College guidelines recommended mammograms every one to two years starting at age 40 and annually beginning at age 50.
This contradicts the 2009 recommendation from the USPSTF, which recommended an individualized approach and against routine screening for women aged 40-49.
No wonder patients are confused.
In our society, which values tests and generally believes that earlier cancer detection is better care, the ACOG recommendations were met with media acclaim.
Gary Schwitzer, for instance, points out the bias in CNN’s reporting the guidelines, and specifically takes senior medical correspondent Elizabeth Cohen’s Tweet on the issue to task:
On many occasions that we’ve written about on this blog in recent years, CNN has demonstrated a bias in favor of screening – touting benefits, minimizing harms. Sanjay Gupta’s badgering of US Preventive Services Task Force member Lucy Marion will always stand out in my mind – and in the minds of many of who saw it – as opinionated “attack” journalism that reflects the polarization we often see in politics now creeping (leaping?) into health care and into health care journalism.
As to which guideline to believe, physicians will be divided. I suspect that physicians who practice more strict evidence-based medicine will go with the USPSTF recommendations, while gynecologists will follow their college’s more aggressive recommendations.
Although I’m a proponent of clinical guidelines, obtaining the needed consensus will be difficult. There are too many proverbial cooks in the pot, with every medical society releasing potentially conflicting recommendations and confusing both doctors and patients.

How Facebook Eclipsed Google In 2010

Facebook beat out Google as the No. 1 most-visited site in the United States in 2010, according to Internet analytics firm Hitwise.

How was Facebook able to outplay the former Web champion? And can Google make a comeback in 2011 and beyond?
Let's begin by admitting that the Hitwise data doesn't represent the whole truth. For starters, Hitwise only measures unique visitors in the United States. What's more, Hitwise measures sites on a per domain basis: If the analytics firm were to include Google-owned YouTube in its calculations, Google's network of websites would outrank Facebook properties.
Nonetheless, there's a tectonic shift at work here: Facebook, once easily dismissed as the next social networking fad, has seemingly discovered Google's weak spots.
What are they, and can Google regain ground here?


Identity Wars
The first area in which Facebook has bested Google is online identity. Remember the days when trying out a new website required entering your name, username, password and other details into a form? Now sites can opt to use your Facebook account for one-click signup, making life easier for both websites and their users.
Facebook was able to make this move because the service was founded around the principle of real names. While this may have slowed Facebook's growth in its early days, the company now owns a massive database of more than 500 million identities, most of them real.
As a result, Facebook is becoming the de facto identity system for the Web. The social optimization service Gigya claims that Facebook accounts for 46% of website logins versus Google's 17%.


Social struggles
Where else is Google behind? How about "social," one of the biggest Web trends of the past five years? Understanding the connections between people is Facebook's core competency, but Google has struggled to compete in the social networking arena.
Google Buzz, widely considered a flop after a highly anticipated launch this year, unsuccessfully tried to turn Gmail contacts into social networking friends. Gmail users, it turned out, didn't need yet another social network, and didn't see their email contacts as synonymous with their real-life friends. That's a major hurdle for all of Google's social efforts: The company doesn't possess a "social graph" of our real-world connections.
More troubling is that social gaming, with such Facebook hits as FarmVille, has become a megatrend over the past few years. Google has few inroads here.
Google is expected to roll out a "social layer" uniting its Web properties in 2011, but the company has played down claims that it will launch a full social network, and expectations are low for Google's next social foray. Google could change its social fortunes through an acquisition, however: The purchase of social messaging service Twitter is the obvious move.


Search Rivalry?
Google is synonymous with search and continued to reign supreme in 2010. Surely this is the one area in which the company can maintain its lead in the coming years.
Google would indeed prove difficult to unseat in search, and yet Facebook may eventually gain a little ground here, too. Not only does Facebook possess a large database of every users' personal preferences, but its increasingly popular "Like" buttons allow members to express interest in particular Web pages.
If the company felt so inclined, Facebook might be able to provide a search engine that delivers highly personalized results. Better still: Facebook may stockpile enough personal information to recommend relevant content without the need for a search box.
Such a move is unlikely to unseat Google overnight, but this means of social discovery could lessen our dependence on search engines in the long haul.


Google's big gains: Mobile, video
Facebook is only "beating" Google if we limit the playing field to the Web. But in the rapidly growing mobile sector, Facebook is a minor player.
While the leading social network is attempting to bring social features to phones, Google owns an entire operating system: Android. What's more, Android is spreading like wildfire and proving to be a real challenger to Apple's iOS. Facebook, meanwhile, doesn't even have an iPad app.
What about watching online video, one of the Web's most popular activities? Yes, Google wins there, too: As the owner of YouTube, the company serves up the vast majority of online video views. In neither mobile nor video does Facebook look to be a threat to Google's position.
Google will always retain the lead, meanwhile, in professional life: From collaborative document creation to enterprise email, it's hard to see Facebook challenging Google's role in the workplace.


An uncertain victory
In 2010, Facebook challenged Google where it is weakest: Online identity and the social Web. Given that "social" is the Web's fastest-growing trend, it's hardly surprising that Facebook has benefited from the rising tide.
And yet Facebook only outranks Google on that very narrow metric: U.S. Web traffic. As mobile operating systems and app stores grow in popularity, is Web traffic really an accurate measurement of an Internet company's success?
and let's not forget that Google still crushes Facebook on the number that really counts: Revenue.

A Happy New Year From Rubben Navarrette Jr.

Rubben Navarrette is the regular contributor to CNN and an NPR commentator,i found the following article so insightful. 

The kickoff of a new year -- and, for that matter, a new decade -- is a good time to look down the road and make a pact with ourselves about the kind of people we want to be and what we're willing to do to get there. These aren't just goals, but resolutions.

I'll start.

With the intention of becoming a better person, more responsible parent, stronger writer, and more productive citizen, I resolve to do the following:

-- Confront constantly my fears, inhibitions, and insecurities instead of being controlled by them

-- Focus on being the best father I can, not be my children's best friend

-- Not be so eager to avoid conflict that I let the whims of a 2-year-old, 4-year-old, and 6-year-old run my life

-- Remember that, while there is never enough time to do everything, the best place to spend it is with family and friends

-- Decide how I feel about issues based on what's best for my country, and not just my city, neighborhood, or group

-- Give people I criticize the benefit of the doubt, and not make assumptions about what motivates them

-- Look for common ground and middle-of-the-road solutions to difficult problems

-- Think through issues from a more complete, 360-degree perspective, examining them from all sides before making up my mind

-- Challenge those on the far right and the far left to approach issues with honesty, nuance, and common sense

-- Continue to try to give a voice to the silent and defend the little guy against the excesses of the loud and powerful

As for Americans in general, we should dedicate ourselves to doing the following:

-- Complain less, vote more

-- Remember that elected officials who serve in Congress, state houses, and City Hall work for us, and not the other way around

-- Think harder, judge less, read more, think again, and keep an open mind, especially when it comes to those things about which we're most unsure

-- Worry less about how others should behave, and concentrate on what we have power over: our own behavior

-- Steer clear of the extremes on the far right and the far left, and learn to see the value in more moderate views that come from the middle

-- Take responsibility for our actions, failings, decisions, and mistakes and don't look for others to blame

-- Resist the temptation to play the victim and give others more power than they deserve

-- Take politics seriously, but parenting more seriously, since the former allows for the repealing of legislation and regular elections to set things right, but there are no "do-overs" if you mess up the latter

-- Travel more and, when we get where we're going, don't forget to talk to strangers

-- Don't be so eager to be heard that we forget to listen to others

We probably can't do all those things. We're going to fall short. But we can try to do many of them. And in the process, even when we fail, we can live better lives and help make this a better country.

And what better way is there to start the new year?
