STOCKHOLM, Sweden (AP) _ Olympic hurdles champion Ludmila Engquist of Sweden will return to competition this week despite continuing to undergo chemotherapy for breast cancer.

The Russian-born Engquist said she will run in Friday's DN Galan Grand Prix meet at Stockholm's Olympic Stadium, the Swedish news agency TT reported.

``I am someone who wants to try to do impossible things. I want to show that it is possible,'' said Engquist, who also holds the world indoor record for the 100-meter hurdles.

Engquist announced in April that she had breast cancer and did not plan to return to competition until 2000.

``But Ludmila has reacted (to chemotherapy) less than expected. Her unbelievable physique has helped her,'' said Arne Ljungqvist, her doctor and chairman of the Swedish Track and Field Association.

``I've trained almost as usual every day,'' Engquist said. ``The training has gone so well that I thought 'why not compete also?' _ it's so boring just to train.''
