En contraste con lo que muchos piensan, las mujeres no fumadores tienen menos probabilidades de morir por cáncer de pulmón que los varones no fumadores, según publica el "Journal of the National Cancer Institute".
Investigadores de la Sociedad Americana de Cáncer explican que son pocas personas no fumadoras las que desarrollan tumores pulmonares, pero que existen otros factores, aparte del tabaco activo, asociados a la enfermedad, como la exposición al humo del tabaco, al amianto o al radón.
Desde hace tiempo, muchos médicos han pensado que las mujeres no fumadores presentaban más riesgo que los varones, pero no es así. Su investigación sobre una muestra de más de 940.000 adultos no fumadores confirmó que mueren más varones que mujeres de la misma edad.
La única diferencia se encuentra en el caso de las mujeres de raza negra no fumadoras, que presentan mayor riesgo de muerte por cáncer de pulmón que los varones.
