(This post is not professional advice. It is the ramblings of an older adult, stomach cancer survivor who reads a lot and has a blog.)
In this study from Osaka University it is alleged that brain cancer (cancer in the brain) can hinder immunotherapy by keeping T cells, the body’s “police” and waste management service, from leaving the bone marrow where they are created. While cancer is a “foot in the door” disease, slamming the door on the intruding foot is just the start of a battle between the normal, law abiding cells and the slower moving intruding cells that write their own script as to where they will migrate next.
Cancer has been with us and other biological entities from the beginning. And our immune system deals with a crafty foe that can can hide out from the immune system, hijack normal cells, and change itself so that it becomes resistant to whatever its host is doing to eliminate its existence. It is also a “dirty disease” where the tumor sheds individual, invisible to the naked eye, cells that can travel anywhere in the body via lymph or blood system. By the time you seek medical attention for its symptoms, it may already be to late to get rid of it.
