Yet another sad story of how the Social Security disability backlog impacts lives.

47-year-old Heather Russell was diagnosed a year ago with Stage IV cancer and applied for Social Security disability benefits. She was initially denied benefits, and so kept working at her job at Home Depot despite the toll the end-stage cancer was taking on her.

Russell died before receiving Social Security Disability benefits. And it wasn't until a few weeks before her death that her family learned that her claim likely could have been expedited because of her terminal condition.

It wasn't until recently, with the help of staff from Congresswoman Carol Shea-Porter's Dover office, that the Russells learned Social Security provides "compassionate allowances," according to the agency, in order to "quickly target the most obviously disabled individuals for allowances based on objective medical information that we can obtain quickly."

But Heather Russell received no compassionate allowance. And she died while her Social Security Disability claim was mired in red tape.

Russell's family says that her final months could have been so much easier had her disability benefits been approved. She wouldn't have had to continue to work and to worry about how to pay her rent and other bills.

Heather Russell's story is a sad reminder of why the Social Security Disability system is sorely in need of reform.
