Woops! Study Accidentally Finds Chemotherapy Makes Cancer Far Worse

[Tenet Nosce]

whether metaphysical or physical i would think that strengthening the immune system would be beneficial to the healing.

The immune system is where the physical meets the metaphysical. It is the place where "identity" is determined on the physical level. You are right, it can be very important. But it's not about strengthening only. Often times, other branches of the immune system are overactive and need to be calmed down. It is often a question of resources, and in a resource-depleted environment, the immune system is forced to choose between addressing the "immediate threat" or looking to the long-term.

That's one reason why nutrition is so important. Balanced nutrition provides enough resources to the immune system so that it can attend to both short-term and long-term considerations of the body.

There is also the angle of carcinogenic toxins coming into the body. And yes it is important to consider these and try to minimize them. But at the end of the day simply being physical is going to cause us to be in contact with carcinogenic substances in our environment.
