Bladder cancer with no metastasis - what is the cause of death?

Hi. I'm sorry to hear what happened. It will be indeed very hard to ascertain the cause of death from this venue but here are some points. Those who die of cancer usually have wide spread disease, or have tumors in vital organs such as the lungs, brain, or liver that compromises their function. Though he did not have this, a localized tumor to the bladder could still have caused damage by compressing other nearby structures such as major blood vessels. This can result to bleeding or thrombosis that can be fatal. The pain may also cause excessive sympathetic activity resulting in increased heart rate, increased blood pressure and overall, can cause the cardiac function and activity to deteriorate. This can be possible especially in the elderly, whose cardiac functions can be compromised in the first place. Some side effects of chemotherapy like neutropenia can cause a patient to be susceptible to overwhelming infections which can be hard to treat. Cancer patients are also susceptible to thrombotic events (formation of clots in the blood vessels) which can lead to a condition called "pulmonary embolism" (clots clogging the blood vessels in the lungs), which is usually sudden and may appear unexplained. Here are just some pointers and I believe it is better to discuss this more with the doctors who attended to him. My condolences to you and your family. Regards and God bless.
