I'm so sorry your loved ones are hurt.

Regarding what can be done to eliminate the spike proteins, your post on eggs is my best guess. Chickens exposed to spike proteins will produce eggs with antibodies to them, and eating those eggs sound like it will also deliver myriad other benefits, including supporting the immune system in handling it's business in every way, such as against cancer.

We all defeat cancer daily, as our immune systems eat cells that have gone awry. If his immune system can recognize the cancer as invasive, it will get eaten and the problem will be solved.

Also, you don't have a cancer diagnosis to fear. I'd be hunting down doctors that can get on the issue right away, not waiting months because some say I have to wait. I'd be looking at ways to diagnosing myself too. Doctors aren't prophets with divine authority. They use tests to give them data they interpret according to rules that give answers. You are certainly competent to find out what those rules are, to do the tests yourself, and decide how to proceed from there. If you can't get service you need in the state, or states, there's other places to seek it, such as Mexico, where I have in the past purchased medications for 1/10 the price of the copay in the USA.

To the degree you are concerned act to resolve the problem in every way available to you. Everyone I know of that died of cancer didn't do that. I cannot say that is why they died, but doing nothing but accepting fate and the decree of gods in white coats cannot help. Never regret not doing what you could is my best advice.

I hope you can learn that there's a way to resolve all his health issues and make it happen.
