Looking for cancer support groups

Hi! So, this past December my mom was diagnosed with breast cancer. All things considered, she was lucky with one of the best possible diagnosis. (Like I said, all things considered). But I think it’s hitting her harder than she’s letting on. My family has been there for her through this whole process as much as we possibly can, but we can only do so much. I really think she needs to talk to people who are going through the same thing and can relate more to her in this situation. I have no clue how to start the conversation or where to look for a good group though. There’s more personal factors in play but everyone’s relationships are at a strain now. I don’t want anything to get beyond the point of repair. So if you have any advice or anything please let me know!
