I have learned a bit more about Jackie Collins and keeping her breast cancer quiet. It turns out she could feel a lump two years before she went to a doctor. She told People magazine shortly before she died that she was scared to tell her doctor because of her family medical history.
I think this is the old face of cancer. Cancer is not what will necessarily kill us these days. Cancer is becoming a chronic instead of a terminal disease. And many cases when diagnosed early cancer is not terminal.
The worst thing we can do is not tell our doctors about our health issues. If we hide from them, ignore them, or pretend they aren't there (guilty of all of these) for too long, the results will not be the most optimal.
And if we do try to pretend they aren't there, of course they will get worse and not better, unless its all in your head anyway. (Yes I am guilty of that as well.)
