Lady Gaga Has Cancer Scare! "I don't want anyone to worry."

Ever since she nearly collapsed on stage in March (click here for that story, even Janet Jackson was reaching out to her!) and had to cancel several shows earlier this year citing exhaustion, Lady Gaga has had us worrying if she's on the verge of tipping.

And now Gaga's latest health scare probably isn't helping to alleviate those fears.

"I'm very connected to my aunt, Joanne, who died of lupus,"

she says,

"It's a very personal thing."

When asked if she's been tested, Gaga, 24, says "yes," without elaborating on the results, adding that she doesn't "want anyone to be worried" even though the disease, in which the immune system attacks the body, can be genetic.

"I have heart palpitations and things. But it's okay. It's just from
fatigue and other things,"

Her most recent health emergency: "The other day," Gaga says about her time in Tokyo where she was "having trouble breathing."

After receiving "a little oxygen," Gaga went back on stage.

"I was okay,"

she says, again adding,

"I don't want anyone to worry."

As for buzz about her thin body, Gaga wants to reassure fans that she doesn't "have an eating problem," but rather points to her busy schedule that doesn't allow her "very much time to eat."

"I really don't do drugs. I don't touch cocaine any more. I don't smoke,"

she says.

"I take care of myself."

But don't expect her to slow down anytime soon.

"People say I should take a break,"

says the singer. "But I'm like, 'Why should I take a break? What do you want me to do? Go on vacation?"

YES!! I believe she may just need as little as 3 days away from the madness. And you may be saying to yourself, why? ...she just got hot and she needs to keep it up before the big fame wears off....I say no way to that, health is more important and everyone knows once you take a break you are rejuvenated and refreshed to start working again.

Good luck Gaga!
