(CNN) — La inteligencia artificial encontró más cánceres de mama que los médicos con años de capacitación y experiencia y redujo la carga de trabajo de lectura de mamografías de los médicos casi a la mitad, encontró un nuevo estudio en etapa inicial.Esto no significa que su hospital permitirá que una computadora determine si tiene cáncer en el corto plazo. Todavía queda mucha más investigación por hacer, pero el estudio, publicado este martes en la revista The Lancet Oncology, muestra que la IA es segura para usar en la detección del cáncer de mama y podría hacer que los médicos sean aún más efectivos para encontrar el cáncer de lo que son ahora.Otros estudios han demostrado que la inteligencia artificial puede ser útil para predecir el riesgo de cáncer de mama, pero utilizan modelos o se han centrado en datos retrospectivos. Se cree que la nueva investigación es el primer ensayo de control aleatorio que compara la detección del cáncer de mama asistida por inteligencia artific...

Published Sat, 22 Feb 2025 08:46:48 GMT

SYDNEY (AP) — Colombia coach Nelson Abadia said 18-year-old star Linda Caicedo is fit and able to play the final Women’s World Cup group game against Morocco. Caicedo has been one of the stars of the tournament so far with goals in Colombia’s opening two games. Her play has put Colombia atop Group H and on the brink of advancing to the knockout stage. But there have been concerns about her health, which has been described as battles with exhaustion and fatigue. Caicedo struggled first in training and then during a 2-1 upset win over Germany, the second-ranked team in the world. She was seen holding her chest and then dropping to the ground during a practice session ahead of the Germany game. Then, late in the match against Germany, she dropped to her knees behind the play before lying face down on the grass as Colombia’s medical staff went to her aid. Abadia said Caicedo has been cleared to play Morocco on Thursday in Perth following medical tests. “She was going through a che...

TOKYO (AP) — Global shares dipped Wednesday after Wall Street took a step back from its big rally as markets tried to digest a slew of earnings.France’s CAC 40 fell 1.3% to 7,311.42 in early trading, while Germany’s DAX dipped 1.4% to 16,007.22. Britain’s FTSE 100 dropped 1.8% to 7,531.78. U.S. shares were set to drift lower with Dow futures down 0.7% at 35,507.00. S&P 500 futures lost 0.9% to 4,558.25.

Treasury Secretary Janet Yellen said the move by Fitch was based on outdated data, noting the U.S. economy has rapidly recovered from the pandemic recession.“Some negativity was permeating across Asian equity markets mid-week than...
