Cancer patients typically suffer from lack of self-respect or worthiness, and often have what I call an "unfinished business" in their life. Cancer can actually be a way of revealing the source of such inner conflict. Furthermore, cancer can help them come to terms with such a conflict, and even heal it altogether. The way to take out weeds is to pull them out along with their roots. This is how we must treat cancer; otherwise, it may recur eventually.
That paragraph made me think of Dr. Christopher in one of his NHS videos where he told the story about him getting sick as an adult and when he really got right down to it, he thought it was because of some unresolved anger from when he was a small child. Aren't we wonderfully made? Yes we are! We just have to know how to treat our bodies.
