He's testing an inhaled version of chemotherapy. She sat in this tent and breathed in the medicine.Dr. Gregory Otterson: The strategy is to deliver chemotherapy agents directly into the lungs. We want to maximize the delivery to the lungs and minimize systemic toxicity.Lisa Fogle: When you think of chemotherapy, you think of hair loss, sickness, fatigue, there was none of that.Jennifer Matthews: It's too early to know if it will work, but earlier animal studies showed a twenty-five percent response rate.Lisa knows the odds are against her. So, she's spending each moment making memories with 6-year-old Joshua.Lisa Fogle: The hardest part for him to deal with is Mommy could die. He'll ask me, 'Mommy, will it be on a Thursday? Will it be on a Friday?' It's like, well, Josh, only God knows that, but hopefully, it won't be for a long time. This is Jennifer Matthews reporting.
