Repealing healthcare law would allow insurers to return to practices that rescind coverage to victims of breast cancer, Speaker Nancy Pelosi (D-Calif.) said Thursday.

Pelosi went on the attack against Republican promises to repeal the healthcare bill she shepherded through the House, pointing to newly-banned insurance industry practices like those at WellPoint, which has reportedly singled out women suffering from breast cancer to drop their coverage.

"WellPoint’s practice of dropping anyone’s coverage when they get sick – whether a woman with breast cancer or any other patient – is exactly the kind of insurance company abuse our new health care law prohibits," Pelosi said late this afternoon in a statement.

But the speaker took it a step further, suggesting that practices like the ones at WellPoint could be revived if the GOP succeeds in repealing the bill.

“And when Republican leaders call for repeal of the health reform law, they are endorsing a return to these abusive policies that have no place in our medical system," she said.

Pelosi's statement marks one of the first steps in what aides have called an "aggressive" offensive by House Democrats to highlight benefits of the health bill that would be threatened by a repeal of the legislation.

House Minority Leader John Boehner (R-Ohio) has called repealing healthcare law his "number one priority," though Republicans differ on whether to pursue a full or partial repeal, if it's even politically feasible.
