Need advice regarding a friend with cancer

I worked with a young woman some years ago and we became good friends. Although she is very attractive, she’s the same age as my daughter and I was her trainer, so there was no romantic interest, etc., just a good friendship.

She moved away to another district office many states away about 5 years ago, and I left the agency, but we have kept in tough sporadically through text messaging, although the contact has become more limited as time passed.

So I just found out from another friend that she has breast cancer and it’s serious. She’ll be going through chemo and surgery; the whole 9 yards.

I’m looking for advice on how best to contact her and provide whatever emotional support I can. I’m unsure because I know there is so much emotional baggage when a young woman gets breast cancer. She’s in her early 30’s and never married. She has no kids, of that I’m sure, but I don’t know what her dating situation is, currently. I wouldn’t want to trigger her current boyfriend, if she has one.

Also, it’s not like she reached out to me to tell this news on her own. I found out through another person. Maybe she wants to keep it private.

So, should I send a text with some words of support and prayer? Maybe send a card in the mail? What about flowers? Is that too much?

My heart really hurts for this nice young lady. Such a sweet person!
