Pop singer Maki Oguro will temporarily suspend her singing career at the end of October to undergo treatment for uterine ailments, her management company said Wednesday.

The timing of the 40-year-old singer's comeback depends on the progress of the treatment, which includes the removal of fibroids in the uterus.

But Oguro's management company, Sunny Side Up Inc., said it hopes she will be able to resume singing in 2012, the 20th anniversary of the start of her career.

Oguro said on her Web site the same day that she has undergone several in vitro fertilization treatments because pregnancy can prevent fibroids from worsening, but her demanding job caused miscarriages.

"By sharing my status, I wanted to cheer up women who suffer alone from similar illnesses," she said.
