The '2 Hearts' singer - who was forced to postpone her 'Showgirl' tour when she was diagnosed with breast cancer in May 2005 - has been warned by specialists such a grueling schedule could have detrimental effects on her health.
A source said: "Kylie is determined to do this tour. She was upset that she had to pull out of the last one - the 'Showgirl' tour - when she received her cancer diagnosis.
"If it was up to her, she'd do an endless string of dates but doctors say she needs to make herself priority and takes more time to relax."
Kylie - who was given the all-clear from breast cancer in early 2006 after having a partial mastectomy and a course of chemotherapy - is finding it difficult to accept she can no longer put her body under such duress.
