Michael Stewart endured three months of night sweats, vertigo and weight loss before he finally went to a free health clinic in San Francisco. Blood and urine tests showed nothing, so the clinic staff sent him to San Francisco General Hospital. That?s when the bills began accumulating ? blood test, X-ray, endoscopy, two colonoscopies, two MRIs, two CAT scans and 10 days in intensive care. And the 48-year-old Stewart didn?t have health insurance. The full-time actor was thousands of dollars in debt before he even received his diagnosis: stage three colon cancer.
