Coosjoaquin, I genuinelly hope your mother experiences a true recovery!
As for cancer, faith, etc., June can only say this:
I somehow can't help but feel that depending on the event and the individual, significant life traumas can cause us to go in either direction. I have heard of believers who in experiencing a tremendous loss reaffirmed their belief, while for some, the opposite was true. The same goes for the atheist: In the midst of an overwhelming trauma or loss, they seek out and find the presence of God.
There is this one individual who became extremely depressed in the aftermath of her husband's death. She had apparently prayed and prayed and prayed for God to intervene and not let her dear husband die. --But he did. What came to pass was the fact that her depression was not just an emotional or psychological state of affairs. Rather, for her, it was a spiritual one. She was angry at God, and felt that her prayers had not been acknowledged and answered. Her depression was more rooted in more of an existential, spiritual angst, and her sense of betrayal and anger by God was absolutely real.
It was only in coming to terms with her own faith, her acceptance of how God had worked in her life that she
truly addressed the source of her depression. It wasn't a matter of needing "analysis," it wasn't a matter of needing medications, but rather, it truly came down to her overcoming a crisis of faith. --But when she did, she was able to go on, accepting both the loss of her husband and her renewed faith in God.
And that is part of the reason why June acknowledges that yes, there does exist a spiritual aspect to human beings...
Cancer, loss, death, and significant traumas all have the capacity to challenge who we are and what we really believe about about ourselves and our existence. I think it's very individual; personal.
There is no right or wrong. It is in our capacity to endure, resolve, and accept our life situations that speaks the loudest to the spirit which all of us seem to possess, regardless of what one calls it.
--So long as we can eventually find peace in ourselves, with ourselves, and acknowledge that.
I believe it's called "hope."
Take gentle care.
