Beth Chapman Rushed to Hospital with Breathing Issues in Wake of Cancer Battle

Beth Chapman was rushed to a hospital after experiencing serious breathing difficulties, this in the middle of her cancer battle ... but whatever triggered the difficulties resolved itself for her to return home.

TMZ has confirmed, Beth was in Hawaii Saturday when it became apparent she needed medical help.

We broke the story ... Beth underwent emergency surgery last November to remove a life-threatening blockage in her throat. Doctors discovered her throat cancer had returned. At the time she was having difficulty breathing, which is what triggered her trip to the hospital.

Beth is undergoing chemo, which she started in January.

Beth vowed after her diagnosis, "I've never been a victim and I won't let cancer beat me."

When she had her surgery, her lawyer, Andrew Brettler, told us Beth's condition was serious.
