One thing that should be understood, is that it is radioactive therapy,
somewhat enhanced, but of radioactive activity, non-the-less,
carries certain ramifications that are unavoidable with that modality.

When you aim a beam of radioactivity at "target A", that beam
has to pass through everything between the "gun" and "target A".

There is absolutely no way to avoid damage to cells between
the gun and "target A".

A cancer cell is nothing more than a normal cell that has been
damaged in such a way, that it can no longer recieve instructions
from the brain/body. If the immune system doesn't remove that
damaged cell, the cell may attempt to continue living by using
a very basic method called "the fermentation process".
(that, is a cancer cell!)

The fermentation process is how one cell organisms remain alive!

It's a simple system, taking in large quantities of glucose (by stealing
it from good cells), and dumping lactic acid into the system. The liver
will turn the lactic acid back into glucose, but it does so under much
duress. The body needs glucose for energy, and denying the body of
glucose will result in a loss of energy, weight, and eventually.... death.

So.... radiation damages cells in order to kill the cell. It might kill a
cancer tumor, but during it's process, it can also damage good cells,
resulting in what is known as "second cancers".

There are good points and bad points to every remedy. It's a terrible
thing to have to decide between the lesser of two evils, but it has to be
decided one way or the other.

There are always options and alternative routes to take, but you have to
consider if there is an emergency situation involved, or not.

If the tumor is about to kill you, you would want to get it out ASAP.
If the tumor is growing, and you have time, then a safer approach to
killing the tumor might be a better choice.

Weigh your options, and do so without the fear of "not doing"; don't
be pushed into a hazardous situation if you can possibly avoid it.

Listen to your basic instincts for survival; your basic intuition....
You were provided that at birth, and for good reason!

"Trust thyself"

Best hopes your way!
