good evening. we have a giant headline to tell you about tonight about health. the topic? breast cancer and alcohol, including wine. the results are in from the biggest study of its kind in history, by the american medical association. 100,000 women followed over 28 years. and the conclusion? less than a drink a day, even a glass of wine with dinner, could change the risk of breast cancer. in whom and why? so, we asked abc's andrea canning to break it all down for us tonight. >> reporter: the new study out today found compelling evidence that having even a single glass of wine each day raises your risk of breast cancer. >> in the past, we've known women who consume a lot of alcohol increase their risk of breast cancer. we actually thought that a small amount of alcohol was relatively safe for breast cancer. >> reporter: the study of more then 100,000 women over a

28-year period shows just 3 to 6 glasses of alcohol a week can increase a woman's chances of breast cancer by 15%. less than a glass of wine per day. and if you bump that number up to two a day, the risk goes to 51%. does it make you think twice about having that extra drink? >> it might. but honestly, probably not. >> if wine is going to give a person breast cancer, i would definitely change my habits. >> reporter: doctors believe as many as 11% of breast cancers are linked to alcohol consumption. the increased risk is caused by the way the body reacts to alcohol. drinking increases levels of estrogen in the body, fueling tumor creation and growth. so what do you do? especially given the fact that we've heard in the past that moderate alcohol use has been found to help prevent heart attack and stroke. >> the increased risk of breast cancer is really dwarfed by the evidence of decreased risk of cardiovascular disease. >> reporter: still, today's study is the most significant bit of evidence that every time

you raise your glass, you might be raising your breast cancer risk. andrea canning, abc news, new york. >> which brings us to abc's chief health and medical editor, dr. richard besser. so, rich, are you confident of this? is this going to be another study we see reversed in another couple of months? >> reporter: this is the best study yet on this question. it's not the first study, but it's the best study. if you have family members, women in your family, who died from breast cancer, there's not a lot you can do. but this says there's something you can do that can possibly reduce your risk. and that's stop drinking. >> so you have looked at all the evidence, you think they are onto something here with all this says? >> reporter: i think they are. >> okay, let me ask you about the other thing we keep hearing, which is a little bit of alcohol, moderate alcohol, prevents heart disease and stroke. so, how do you choose between the two? >> reporter: well, that's the catch. if you don't have that breast cancer risk, you have to remember that a small amount of alcohol, one drink a day or less, has been shown in lots of studies to reduce your risk of heart disease.

and you have to remember, 1 in 3 women are going to die from heart disease. only 1 in 36 are going to die from breast cancer. so, it may be worth continuing to have that drink, if you don't have the increased cancer risk. >> so start by taking a look at your risk factors and then decide which course you're going to take. >> reporter: and if you don't drink now, no one is saying to start drinking. there are too many things that can go wrong with starting drinking. but look at your our risk factors and that should help you decide. >> okay, thanks, rich. as we said this is a really big new study and big conclusions. and now, we turn to that david versus goliath story, the victory of people power against a huge bank. bank of america announced today it is reversing itself on those new $5 customer fees. and we have been covering this since the beginning. you'll remember the young woman who started the petition against the bank, raising fees after the taxpayer bailout. customers moved in, it spread like wildfire. we tracked down the head of the company to try to get answers and abc's matt gutman, who did

that, has been on the story from the beginning, and takes us inside the grass roots revolution and what happened tonight. >> reporter: it took 33 days. 300,000 petitioners. and one molly katchpole. >> i won! i know! so exciting. >> reporter: when katchpole, just 22, was first features on abc news last month, she had just launched an online petition demanding bank of america repeal its, quote, outrageous $5 debit fee. >> it's crazy. it's at 125,000. >> reporter: today, 306,000 signatures. >> i just happened to be the person that started the petition. but if it wasn't for the 306,000 people who signed it, it wouldn't be anywhere. >> reporter: her public outcry over the debit fee echoed from the senate floor -- >> bank of america customers, vote with your feet. >> reporter: all the way to the white house. >> you're going to see a bunch of the banks who say to themselves, you know what, this is actually not good business practice. >> reporter: at first, the bank wasn't listening. several other big banks saying

they, too, were thinking about adding the fees. wonder if you could answer a couple of questions for us, sir. so, we tracked down bank's ceo in washington, looking for answers. does bank of america need that money in order to stay alive? >> well -- the fee is meant so we can provide the great services we provide for our clients. >> reporter: so, the outrage and the public outcry continued, spurring other big banks like chase and wells fargo to kill plans to roll out their own debit fees, forcing bank of america to buckle. "our customers' voices are most important to us. as a result, we are not currently charging the fee and will not be moving forward with any additional plans to do so." and all of it started with that quietest, quaintest of protests. a petition. >> i really hope that this inspires other people to try to change things when they're unhappy with them, you know? even if it is something like starting a petition. >> reporter: and analysts say it wasn't just those voices that forced that change but a silent army of people, diane, marching their money away from the big banks. traffic on the national federal credit union website is up a

whopping 700%. diane? >> and so many people thought they would never react, never respond and they did today. thank you, matt. and for all of your reporting on this issue. 24 hours ago, by the way, the stock market was surging, you may remember, and optimistic. but if you were watching your stocks today, you saw a nose dive. the dow down nearly 300 points, so, what changed? well, blame it on the country of greece, long criticized for being undisciplined and now threatening american retirement. here's abc's dan harris. >> reporter: to understand how the problems in tiny greece, 6,000 miles away, directly impact our savings right here in america, meet emma mcfarland and yannis latinakis. yannis is from athens, a former bank teller, who retired two years ago at the age of 52. emma, who's 60 and lives in nokomis, florida, is still having to work around the clock and doesn't have enough savings

to retire. >> it's just not going to happen. >> reporter: and check this out. while our maximum social security payment is around $28,000 a year, over in greece, where yannis lives, it's 20 grand more, $48,000 a year. >> i kind of wish i lived in greece right now. >> reporter: don't we all. this is a country of generous benefits, of pools and porsches and massive tax evasion. and so here is how emma is now paying for yannis. in order to pay for all the retirement packages for people like yannis, the greek government borrowed big time from banks all over europe. now, greece says it can't pay. so, those banks are facing huge losses and that could push europe into a depression. since america does so much business with europe, we would be pulled down, too, and that, of course, would hurt emma's savings. the rest of europe has offered to bail greece out, if greece imposes some fiscal discipline.

but today markets all over the world were rocked by greece saying they want to think about it. >> really don't appreciate it, you know? especially since it is impacting me. >> reporter: yannis told us today he feels guilty about his fat pension plan. but many other greeks are unapologetic. even rioting over budget cuts. leaving emma shaking her head tonight. dan harris, abc news. and we want to bring you up to date now. because for the first time in their young lives, the 2-year-old conjoined twins are living apart. doctors in northern california separated angelica and angelina, who were joined at the chest and abdomen. and after the initial operation, the twins were taken to separate operating rooms for reconstructive surgery. and surgeons gave an update a short time ago. >> we're very pleased to let you know that the surge rip was

successfully completed. we have a long recovery to entertain yet but we're very pleased. things basically could not have gone better. the republican presidential hopeful herman cain was in washington today, but he couldn't escape questions about those sexual harassment allegations. "the washington post" reports that a lawyer for one of cain's accusers wants the national restaurant association to lift a confidentiality agreement that bars her from talking about the case. the woman and cain worked for the trade group in the 1990s. cain has denied those allegations. and word today that secretary of state hillary rodham clinton's mother has died at the age of 92. mrs. clinton has said she was a kind of north star for her famous daughter, who has talked about the strength her mother passed on. dorothy emma howell, born in 1919 and abandoned as a child. >> i've thought of what my own mother went through in her life

as a child, born to teenage parents who couldn't take care of her. at 14, she went to work, caring for a family's children. >> reporter: later, she would marry a traveling salesman, hugh rodham, becoming a full-time homemaker, raising three children in park ridge, illinois. one of them, a little girl who was being bullied and had to learn about true grit. this is a rare interview with oprah in 2004. >> we moved into this new house, new neighborhood, and she would come in crying and screaming about the fact that she had been sat upon by a group of children and she came in one day and i said, "this is just about enough, hillary." >> look at that face. so cute. >> anyway, i said, "just go out there and show them they're not afraid. and if she does hit you again," which she kept doing, "hit her back." >> reporter: dorothy rodham was always there, though mostly in the background.

always watching. and in the 2008 presidential campaign, she taped a campaign ad for her hillary. >> what i would like people to know about hillary is what a good person she is. >> reporter: for the last five years, she lived in her daughter's home in washington. a mother who had no real nurturing herself, cheering her daughter's victories, consoling her defeat. in her book, hillary clinton wrote that her mother's life made her appreciate her own life so much more, adding, it was her mother who said she should never be a quitter. and still ahead right here on "world news," an entrepreneur, blocked by the u.s. government from creating american jobs? what's going on? a made in america investigation. and a woman designated the happiest woman in america. what are the secrets of her life for everyone else? i've got nothing against these do-it-yourself steam cleaners.

and now, a made in america investigation. last night, we told you about road blocks keeping hundreds of thousands of tourists from coming to america, who are ready to spend $600 billion on u.s. goods. well, tonight, abc's david muir looks more closely at a road block aimed at entrepreneurs, eager to set up shop on u.s. soil, hire right here in the u.s. but instead, why are they being turned away? >> reporter: take a walk through so many american high tech companies and you'll find the same thing at the top. ceos, foreign entrepreneurs, who chose america to start their businesses. and employed millions of americans in doing so. among the companies, google, yahoo! pfizer, even ebay. selling just about everything and sold on doing it in america. in fact, in just ten years time, foreign entrepreneurs who fought to get visas to america and got them created 450,000 american j jobs. and that's just the high tech sector. so why is it so difficult for

foreign entrepreneurs today to get a visa to stay here, even when they're sitting on next big thing, and want to employ americans to get it done? take amit aharoni. a stanford business school grad from israel who invented cruisewise.com, an online booking engine, just like orbitz or expedia, only for cruises. he's already hired nine american employees and his company rated one of the hot 20 silicon valley start ups to watch. investors so confident, they poured in more than a million dollars already. after all, he'd come to america for an education. stanford was so impressed when he applied, a hand-written note from the dean "congratulations," he wrote. "your commitment to innovation, to proving that anything is possible will ensure that you succeed." but the question now, where? because amit just learned from the u.s. government his visa has been denied. now he's running his company from a friend's living room in canada. >> how is everyone doing? >> reporter: they give him a

thumbs up. skyping form 900 miles away. how frustrated are you? >> i'm extremely frustrated. this entire situation, i find it outrageous. >> reporter: on hold, his long-term hopes to eventually hire hundreds of americans. does this mean you might take those jobs you created here in america elsewhere? >> i would hate to have that happen but i might be forced to, yeah. >> reporter: economists, even new york city's mayor, say time is money. money that would be spent here and jobs that would be created here. so, you have other countries looking at people who have been educated in america and they say, come start your business here. >> absolutely. and we say go. we don't even give them the option of staying here. >> reporter: and bloomberg says if america doesn't roll out the red carpet, other countries will. china, he says, already offering not only visas, but startup cash. and chile? ♪ beyond the chilean music and the animated handshake, the offer of cold hard cash, incentives. the kind of help amit didn't even ask for here in the u.s. for a company industry leaders
