Sharon Osbourne had a double mastectomy
Virginia Sherwood / NBC
By Alexis L. Loinaz, E! Online
Sharon Osbourne has taken firm, decisive steps to safeguard her health. The "America's Got Talent" judge revealed that she underwent a double mastectomy after doctors discovered she carried a gene that made her susceptible to breast cancer.
The news, which she shared in the latest issue of Hello! magazine, comes 10 years after Osbourne survived a battle with colon cancer.
TODAY Health: More women getting double mastectomies
"I've had cancer before, and I didn't want to live under that cloud," Osbourne, 60, tells the mag, as excerpted by the Daily Mail. "I decided to just take everything off, and had a double mastectomy."
The course of action she needed to take, she added, was a clear and swift one.
"For me, it wasn't a big decision, it was a no-brainer," she explained. "I didn't want to live the rest of my life with that shadow hanging over me."
Sharon Osbourne addresses America's Got Talent departure rumors
A big factor in her decision? Her new granddaughter, Pearl, whom son Jack Osbourne and his now-wife, Lisa Stelly, welcomed in April.
"I want to be around for a long time and be a grandmother to Pearl," she said. "I didn't even think of my breasts in a nostalgic way. I just wanted to be able to live my life without that fear all the time."
She also noted, "It's not 'pity me.' It's a decision I made that's got rid of this weight that I was carrying around."
Jack Osbourne diagnosed with multiple sclerosis
The intimate revelation arrives four months after Jack was diagnosed with multiple sclerosis.
Shortly afterward, she openly wept on "The Talk" about the impact the news had on her, while thanking everyone for their well wishes.
"He's doing really, really good, and I want to thank everyone for all their texts and goodwill and love they've sent to us." she said. "I really believe that vibes and prayer help."

Electron microscopes with a twist: Vortex beams, rotating like a tornado, offer new possibilities for electron microscopy
ScienceDaily (Nov. 5, 2012) ? Vortex beams, rotating like a tornado, offer completely new possibilities for electron microscopy. A method of producing extremely intense vortex beams has been discovered at the Vienna University of Technology (TU Vienna).
Nowadays, electron microscopes are an essential tool, especially in the field of materials science. At TU Vienna, electron beams are being created that possess an inner rotation, similarly to a tornado. These "vortex beams" cannot only be used to display objects, but to investigate material-specific properties -- with precision on a nanometer scale. A new breakthrough in research now allows scientists to produce much more intense vortex beams than ever before.
Quantum Tornado: the Electron as a Wave
In a tornado, the individual air particles do not necessarily rotate on their own axis, but the air suction overall creates a powerful rotation. The rotating electron beams that have been generated at TU Vienna behave in a very similar manner. In order to understand them, we should not think of electrons simply as minuscule points or pellets, as in that case they could at most rotate on their own axis. Vortex beams, on the other hand, can only be explained in terms of quantum physics: the electrons behave like a wave, and this quantum wave can rotate like a tornado or a water current behind a ship's propeller.
"After the vortex beam gains angular momentum, it can also transfer this angular momentum to the object that it encounters," explained Prof. Peter Schattschneider from the Institute of Solid State Physics at TU Vienna. The angular momentum of the electrons in a solid object is closely linked to its magnetic properties. For materials science it is therefore a huge advantage to be able to make statements regarding angular momentum conditions based on these new electron beams.
Beams Rotate -- With Masks and Screens
Peter Schattschneider and Michael St?ger-Pollach (USTEM, TU Vienna) have been working together with a research group from Antwerp on creating the most intense, clean and controllable vortex beams possible in a transmission electron microscope. The first successes were achieved two years ago: at the time, the electron beam was shot through a minuscule grid mask, whereby it split into three partial beams: one turning right, one turning left and one beam that did not rotate.
Now, a new, much more powerful method has been developed: researchers use a screen, half of which is covered by a layer of silicon nitride. This layer is so thin that the electrons can penetrate it with hardly any absorption, however they can be suitably phase-shifted. "After focusing using a specially adapted astigmatic lens, an individual vortex beam is obtained," explained Michael St?ger-Pollach.
This beam is more intense by one order of magnitude than the vortex beams that we have been able to create to date. "Firstly, we do not split the beam into three parts, as is the case with a grid mask, but rather, the entire electron stream is set into rotation. Secondly, the grid mask had the disadvantage of blocking half of the electrons -- the new special screen does not do this," said St?ger-Pollach.
Thanks to the new technology, right and left-rotating beams can now be distinguished in a reliable manner -- previously this was only possible with difficulty. If we now add a predetermined angular momentum to each right and left-rotating beam, the rotation of one beam is increased, while the rotation of the other beam decreases.
Electron microscopes with a twist
This new technology was briefly presented by the research team in the "Physical Review Letters" journal. In future, the aim is to apply the method in materials science. Magnetic properties are often the focus of attention, particularly in the case of newly developed designer materials. "A transmission electron microscope with vortex beams would allow us to investigate these properties with nanometric precision," explained Peter Schattschneider.
More exotic applications of vortex beams are also conceivable: in principle, it is possible to set all kinds of objects in rotation -- even individual molecules -- using these beams, which possess angular momentum. Vortex beams could therefore also open new doors in nanotechnology.

Humana posts lower 3rd-Qtr net income
LOUISVILLE, Ky. (AP) ? Health insurer Humana Inc. said Monday that its third-quarter net income fell 4 percent as more premium dollars from its members went to pay for medical claims, offsetting continued growth in its lucrative Medicare Advantage business.
But its earnings still beat analysts' expectations and the company raised its earnings forecast for the full year.
Humana also announced a deal aimed at solidifying its Medicare Advantage business, especially in Florida.
And the company said that a top executive being groomed as its next CEO will take over those daily management duties soon. Bruce D. Broussard, the company's president since last December, will double as chief executive officer effective this coming Jan. 1.
Michael B. McCallister, who guided the company's growth as CEO for 12 years, will become non-executive board chairman. McCallister's plans to retire as CEO were disclosed a year ago. He said the transition plan has progressed in line with expectations.
"Bruce has confirmed our board of directors' initial confidence in his ability to lead Humana successfully for many years to come," McCallister said in a conference call with industry analysts.
Louisville-based Humana said it has agreed to acquire Metropolitan Health Networks Inc. in a deal aimed at strengthening its Medicare Advantage business, a government-subsidized comprehensive health insurance for seniors.
Metropolitan Health coordinates medical care for Medicare Advantage and Medicaid recipients, primarily in the crucial Florida market. Under the agreement, Humana will pay $11.25 per share in cash to acquire Metropolitan Health's outstanding shares. That part of the deal is worth about $500 million. Humana said it will also assume Metropolitan Health's debt. Humana said that and transaction costs will boost the total value of the deal to about $850 million.
The transaction, subject to Metropolitan Health shareholder approval, is expected to close early next year.
In another deal, Humana said it has acquired Certify Data Systems, which specializes in health information exchange technology. Certify Data specializes in connecting health care providers so they can share patient health information in real time. Terms of that transaction were not disclosed.
In the conference call with industry analysts, Broussard said Humana plans to build about 15 primary and chronic care centers as part of its expansion efforts.
In its earnings report, Humana reported net income of $426 million, or $2.62 per share, in the third quarter. That's down from $445 million, or $2.67 per share, a year ago. Analysts polled by FactSet expected earnings of $2.05 per share.
Revenue rose to $9.65 billion from $9.3 billion a year ago. Analysts expected $9.88 billion.
Humana said it now expects to earn $7.25 to $7.35 per share in 2012, up from its previous estimate of $6.90 to $7.10 per share. Analysts had expected earnings of $7.12 per share for the year.
The company cited improvement in its medical claim reserves and higher enrollment in its stand-alone Medicare prescription drug plans for raising its full-year earnings estimate.
Looking ahead to 2013, Humana forecast earnings of $7.60 to $7.80 per share next year. But analysts had expected more ? an average of $7.82 per share.
Its shares fell $1.22, or 1.6 percent, to $73.99 in morning trading Monday. Humana shares are still up almost 24 percent from a 52-week low of $59.92 in late July. They traded as high as $96.46 in mid-January.
The company was coming off disappointing second-quarter results caused by higher Medicare Advantage costs and increased health care use by its plan members. Broussard said the latest results show those issues have stabilized.
"We believe our improving operations and continued Medicare membership growth, together with our integrated care delivery system investments, position Humana well for a dynamic future," Broussard said.
Humana's third-quarter earnings, however, were dragged by the trend in which a higher percentage of premium dollars from its members are going to pay for medical claims in its retail and employer group segments.
Humana reported pretax income of $424 million in its key retail segment, down by $117 million from the year-ago period.
Its individual Medicare Advantage membership surpassed 1.9 million as of Sept. 30, up 18 percent from a year ago. Those plans offer privately run, government-subsidized comprehensive health insurance for seniors with extras likes vision or dental coverage in addition to basic Medicare coverage. Humana said its group Medicare Advantage membership reached 395,700, up 25 percent from a year ago.
Membership in its individual stand-alone Medicare prescription drug plans rose 19 percent to nearly 2.95 million as of Sept. 30. Humana's position in that market has benefited from teaming with Wal-Mart Stores Inc.
Pretax income in its health and well-being services segment totaled $148 million, compared to $83 million a year ago. The increase mainly reflected growth in Humana's pharmacy business.

Only 20 per cent of Android owners use security apps: Trend Micro
One in five Android device owners use a security app, despite increasing number of malware targeting them.
That is what Trend Micro has found in its Security Roundup Report for Q3 2012, with malware targeting Andoird increasing six times during the three months ending September.
Android malware increased from approximately 30,000 in June to almost 175,000 in September, with ?aggressive adware? being the key culprit in Android privacy attacks.
Trend Micro CTO, Raimund Genes, says these aggressive adware apps are capable of collecting more personal information than the user has permitted.
?App developers may even be aware of the problem, thanks to the existence of rogue ad networks,? he said.
As for the huge increase in mobile malware, Genes says it does not come as a surprise, especially considering that Android is the dominant smartphone platform.
?The digital underground reads the statistics and analysts reports as well, and they figured out way to make money with mobile malware,? he said.
?And unlike your computer, getting information from your phone also reveals your location, the phone numbers you have called, and more, all which could be sold.?
However, despite the growing threat of malware, Genes says that only 20 percent of Android owners use a security app on their device.
?Users need to understand what permissions apps seek, before approving them and unintentionally sharing sensitive information,? he said.
