(Al Jazeera) – Asmaa al-Bahnasawi is a 45-year-old cancer patient who has been unable to receive chemotherapy sessions in the besieged Gaza Strip. She was diagnosed with breast cancer months ago, and like more than 8,200 cancer patients, has been denied treatment until further notice because of a scarcity of chemotherapy drugs. “How could this happen?” Bahnasawi told Al Jazeera from the Gaza Strip’s sole hospital that treats cancer patients.
