Cancer Expenses

My Brother, Tom, was diagnosed with cancer in November 2018 (his wife, Cheryl, was diagnosed in late 2017). As you know, the cost of Chemo treatment is enormous. With a limited income, Tom could use a "little help from his Friends" to  help ease this financial burden so he can concentrate on getting well and living longer. Who knew that the Cancer would come back twice as bad as before only after 3 months. The prognosis wasn't good but new meds will hopefully get the job done or at least prolong the inevitable. 
Any help will be greatly appreciated. Much love...
