Credits to oncology department and Dr Ng Yi Siang. PET scan was conducted smoothly without unnecessary 1-night admissions. Appointments and chemo treatments were also done fast and efficiently. Entire hospital stuff, including the personnel and nurses at chemo day care, are very caring and make us feel really comfortable.
