Symptoms - any suggestions

My mother had a hysterectomy years ago. She is now having bleeding when she goes to the bathroom. She started out with a UTI and they treated her for that. She is still in severe pain. She hurts when she walks or even sitting up. She does not get much relief when lying down either. They have checked her for blood in the urine and there is none. However when she goes to the bathroom there is blood on the paper. She is having spotting off and on and then sometimes it is more like she is on a period. She has burning with urination and severe pain with bowel movements. She is also experiencing constipation quite frequently. She said when she wipes that she can feel something bulging that is very painful. I looked at her tonight to see how serious this really is. From the outside you can not see anything. Even when you pull the lips apart you can not see anything. However when you open up the vaginal opening, there is a very small pin hole there nothing like the size that could hold a tampon or penis. This is a very, very small opening. This is also something else that is bulging and closing that area off. She said it feels like her insides are coming out. I have looked up information about prolapsed vagina and some cancers. I am just scared at to what this could be. Her mother died at 52 from cancer (breast and others) and my mom is 51 now.

Sorry to have been graphic. I am overwhelmed as she was just diagnosed with Basal Cell Carcinoma (skin cancer) this week and my husband was diagnosed with Stage 4 colon cancer on 8/10/09. I am only 31 myself and this is a lot to handle all at once.
