Well found.

Very interesting that the tumours may not be the direct result of migration from original tumour.

It begs the question why.

It also offers hope that reducing levels of in appropriate oxidation, changing nutrition etc after initial diagnosis might help reduce the chances of subsequent brain involvement.

I await more info

Thanks
