Linda's Medical Fund

About 2 1/2 years ago, my mother started having pain in the middle of her back.  She thought it was just a reoccurring problem from a previous injury, but it kept getting worse despite going through the usual therapies.  So after a couple of months, she had a MRI done.  The results were serious.  She had at least one cancerous lesion on her back near her spine.  Since that MRI, she has had more scans, radiation, chemo treatment and numerous hospitalizations.  She has had some success in fighting this cancer, but the costs have accumulated to this point to about $50,000 in bills and debt, with continued ongoing costs with her treatment.
My Mother has worked very hard through her life, without breaks or vacations.  We were hoping she could have a little fun and enjoyment after all the hard work, then this happened.  She can't work at this point  and certainly cannot enjoy her life until she gets this cancer under control.  She has no income to pay these bills.  My dad is a disabled Viet Nam War veteran, so they have very limited financial means. Please help.
