As we reported ... Pink previously postponed two shows in Washington state earlier this week, explaining "family medical issues require our immediate attention."
Now, Pink's postponed four shows altogether this week ... and she's not indicating when she may be back onstage. After Vancouver, her next scheduled gig is Wednesday in Denver, followed by a pair of shows in Kansas City.
Pink's also got a ton of tour dates in November ... and then she's got a scheduled break for the holidays before picking up the overseas portion of her tour in February when she goes to Australia.
In the meantime, Pink says ... "I wish everyone good health and am sending lots of love."
