I Hate Cancer

My mother has had a cyst growing somewhere around/on her ovaries for years. Her doctor told her it was very small at the time and was benign and didn't need it removed or treated. Fast forward to today, my mom has done nothing but vomit and lay in bed with severe pain in her lower abdomen. She has been very gassy and using the be bathroom a lot. When it got to the point where she nearly passed out, she went to the ER. The doctors found that the cyst had fluid in it and had grown to 4 inches wide, bigger than any of them had seen before. She will need surgery and will need to get checked for cancer. My question is, do you think she has cancer? I'm very worried about my mother.
