QUEBEC - Quebec superstar Celine Dion is suspending all of her show business activities to focus on her family and the health of her husband Rene Angelil.

Angelil had surgery last December to have a cancerous tumour removed.

Dion released a statement this morning saying it has been a "difficult and stressful time" trying to fight the disease while raising three young children and balancing her singing career.

She has also been grappling with inflammation in her throat muscles, the statement said, and hasn't been able to perform her scheduled Las Vegas shows since July 29.

All of her performances at the Colosseum at Caesars Palace have been cancelled until further notice.

She will also scrap her tour of Asia, scheduled for the fall.
