[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. Cancer is systemic disease. In letter stage of disease, it can affect almost all organs of the body. So sudden death in cancer patient can be due to any of the following. 1. Sudden Cardio respiratory arrest. 2. Brain death due to brain metastasis. 3. Pulmonary embolism due to involvement of Pulmonary vessels. 4. Severe deny Chat Doctor.  You need to get done postmortem to rule out exact cause for death.
