It sounds like you have a good handle on how you're feeling about your strong connection to your therapist, and I have a feeling that connection will last a long time into the future. If your therapist is off for a period of time while she's getting treatment, I hope you don't dismiss the value in going and talking to a person she might recommend just to work through the stress and anxiety regarding her illness. I'm sure she'd recommend someone good! It doesn't mean that person becomes your new therapist, just someone to talk to for a short time while your therapist is healing.

I did want to say that my mother was diagnosed with cervical cancer when she was in her mid-fifties. She's 85 now! She was hospitalized for a short time following the removal of her cervix and her uterus was also removed as a precaution. She didn't have to have chemo or radiation and she made a full recovery very quickly. Yes, it was scary as she worried about it reoccurring but she's alive and kickin' to this day.
