With the development of the Greater Bay Area, many people have moved to the GBA for work or residential reasons. Moreover, with the long waiting time for public hospitals in Hong Kong and the high cost of private hospitals, more and more Hong Kong cancer patients, especially the elderly, are seeking treatment in the GBA. Cancerinformation.com.hk Charity Foundation has received many inquiries from patients and therefore set up the GBA Medical Information Hotline to answer cancer patients' inquiries about drugs and the hospitals in the GBA.
