I'm glad I was able to give you some helpful information. Thank you for your concern. I was surprised when I was told the mucinous cancer was rare. I thought oh great! I had been trying to find out more about this cancer, online & through books at the libarary. I have found some info online, but even if you type in the full name, etc., other names of cancer show up. It can be frustrating. I have found it has helped me talking about my cancer with other paitents & family. I have gotten insight & encouragement when discussing this with other paitents & it is kinda like therapy, I don't have to keep it all in. I hope your mom is doing well. It all depends on what type of chemo she will get. She may be able to handle the chemo, it all depends on her chemistry & makeup. Hang in there! Take care.
