At 3:44 am on 5/12/24, dad had difficulty breathing, so we called 911 and he was rushed to the emergency department at San Leandro Kaiser Medical Center. He was in the ICU for 6 days for further evaluation. His lymph nodes were also seen to be swollen, that led to diagnosis of stage 4 cancer of unknown primary origin. He was later transferred to a regular room while on non-invasive ventilation (BiPAP) to compensate for his low oxygen level. Due to his weak lungs, chemotherapy was not recommended until he regains his strength. His breathing condition continuously worsened, coupled with respiratory complications. Dad eventually passed away from cardiopulmonary arrest at 5:15 am on 5/23/24. He died peacefully in his sleep, while holding mom's hand by his bedside.
