School gate friend of many years standing, late 40s, diagnosed with BC this summer after finding a small lump in her breast. It was removed and she is recovering well, but she's been told she has to go back and have another op, as presumably they've found more. What does this mean? Is it more serious if you have more than one lump? A different stage? I don't know if the new lump is in breast tissue or lymph nodes or what and I'll find out when I see her, but I didn't want to question her via text. It would be good to not be too ignorant when I see her though and I don't want to downplay it if this actually makes it more serious. TIA
