Leslie, I just read your message and I am feeling your pain. My husband was diagnosed with the same thing October 2006. He had hernia repair in Sept. 2006 and just couldn't get his strength back and was very tired all the time. He began having pain in his stomach. He had no appetite and started losing weight fast. He went to a Gastroenterologist and he scheduled him for a Colonoscopy & Endoscopy. That didn't show anything but the doctor did discover that his pancreas appeared to be swollen so scheduled a CAT scan the next day. The call came a few days later that he had a large tumor in his stomach and referred him to a surgeon. After examining my husband and the scan he determined that he had Retroperitoneal Liposarcoma. He didn't schedule his surgery until November 28, 2006. During that time his pain got worse, he kept losing weight, had no appetite and his stomach was swelling daily. The surgery only took about 4 and half hours. He removed a 20 lb tumor, left kidney, spleen, left adrenal gland and half of his pancreas. He was in really bad shape. He has had 2 scans since then and is scheduled for his 3rd on October 22, 2007. He went back to work on March 1st but he has no energy and worries all the time. He is scared all the time. He still has a lot of pain in his stomach but he has put all of his weight back on. He was 57 when he was diagnosed. I don't know what the future holds but there isn't a day goes by that I don't think about him dying. This has changed our lives so much. I wish your mother all the best and I can totally relate to what you are going through. I try to read all I can. I want to know as much as I can. I want to be prepared for what may come. Bobbie (WV)
