Older women with excess body fat, even if they have what's considered a normal body-mass index, could be at greater risk for breast cancer, according to a study published Thursday in the medical journal JAMA Oncology."We do find that excess body fat in those who are post-menopausal with a normal body mass index is associated with about a doubling in the risk of estrogen-dependent breast cancer," said Dr. Andrew Dannenberg, one of the study's authors and director of cancer prevention at the Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine.The American Cancer Society says estrogen-dependent cancers, called ER-positive breast cancer in the study, occur when the receptor proteins in or on cells attach to the hormone estrogen and rely on it to grow.The researchers studied 3,460 American women between the ages of 50 and 79 who had gone through menopause. The women were part of the Women's Health Initiative and had their body composition measured at the beginning of that program, Dannenberg said. Of those women, 146 developed ER-positive breast cancer, and the researchers looked for a relationship between excess body fat and the development of this cancer. 1190

One of the most entertaining World Series of all time is going the distance.The Los Angeles Dodgers have forced a decisive Game 7, winning Game 6 at home 3-1 against the Houston Astros on Tuesday night."I think it seems fitting," Dodgers manager Dave Roberts said about this series needing all seven games. "You've got the two best teams in baseball going head to head. Like we've talked about from the beginning, these two teams mirror one another. And the compete and fight in both teams is the most important thing I see as similarities. But, again, we worked all year long to have home-field advantage, and here we are. It's only fitting for this series, yeah."Justin Verlander, acquired by Houston for a deep postseason run, was dominant through the first five innings. He had a 1-0 lead thanks to a solo home run by Astros leadoff hitter George Springer in the top of the third off Dodgers starter Rich Hill. It was Springer's fourth home run in this World Series, making him the only other leadoff hitter aside from Lenny Dykstra (1993) to accomplish that feat.But the Dodgers got to Verlander, the former Detroit Tigers ace, in the bottom of the sixth with an RBI double by Chris Taylor and an RBI sacrifice fly by Corey Seager.Joc Pederson added a solo home run off Astros reliever Joe Musgrove in the bottom of the seventh. It's Pederson's third home run of the World Series.Verlander went six innings, allowing two runs on three hits, striking out nine.Hill lasted 4 2/3 innings, giving up the one run, one intentional walk and four hits on 58 pitches. He struck out five.The Astros have never won a World Series in their completed 55 seasons. Only the Cleveland Indians (69 years) and Texas Rangers (57 years) have had longer current championship droughts than Houston. The Dodgers last won the Fall Classic in 1988.This marks the 39th time in a best-of-seven World Series that the Fall Classic has extended to a final game (including 1912, when eight games were played following a Game 2 tie). The Dodgers will attempt to become the 21st team to come back from down 3-2 in the Fall Classic under the current seven-game format.Of the 40 times that a team leading 3-2 has dropped Game 6, it has gone on to win the series 18 times, which is 45%. Ten of the last 12 teams to lose Game 6 with a 3-2 lead went on to lose the series. The last three teams with a 3-2 lead to lose Game 6 and win the series were the 2014 Giants, the 1997 Marlins and the 1975 Reds.This year's Fall Classic has been full of power -- these teams set the record for most home runs in a single World Series with 24 so far -- and dramatic comebacks. Game 5 was the craziest of all, ending with a 13-12 Astros walk-off win in the 10th inning."This series has been back and forth," Astros manager A.J. Hinch said Tuesday after Game 6. "And two incredible teams, trying to get to the finish line. And so now, now obviously it's good for our sport. Necessarily bad for us, because we wanted to win tonight. We'll get back to the hotel, where we'll collect ourselves. Both teams will be ready to play with about as much energy as you could possibly imagine in Game 7."First pitch for Game 7 is scheduled for Wednesday at 8:20 p.m. ET. Yu Darvish will start for Los Angeles. In Game 3, he lasted just 1 and 2/3 innings, the shortest outing of his major league career. Lance McCullers Jr. will start for Houston. 3395

OKLAHOMA CITY (AP) — Two former Oklahoma jail employees and their supervisor face misdemeanor charges after investigators found they played the children's song "Baby Shark" on repeat to punish inmates. Authorities say at least four inmates were forced to stand for hours with their hands cuffed behind them while the song played on a loop at a loud volume. Oklahoma County District Attorney David Prater says he would have filed a felony if that had been an option. Sheriff P.D. Taylor tells The Oklahoman that the two employees resigned during an internal investigation and the supervisor retired. 606

One suburban Georgia county has become a flashpoint for concerns over voter suppression for rejecting hundreds of mail-in absentee ballots weeks before Election Day.Gwinnett County, located northeast of Atlanta, now faces two federal lawsuits and accusations from voting rights activists who say the rejections disproportionately affect minority voters, particularly Asian Americans and African Americans.The county has rejected 595 absentee ballots, which account for more than a third of the total absentee-ballot rejections in the state, even though Gwinnett County accounts for only about 6% of absentee ballots submitted in Georgia, according to state data analyzed by CNN Friday.Officials tossed out the ballots due to missing birthdates, address discrepancies, signatures that do not match those on registration records and other issues, according to the data.A lawsuit brought by the Coalition for Good Governance on behalf of a group of Georgia voters demands that a judge order the county to notify voters within one day of the rejections and provide adequate time to address the discrepancies. 1112
