my 31 year old husband was told he had stage 3 rectal cancer in april 2009. He went through cemo radio and many surgery over a year and a half. march of 2010 was his last surgery and the cancer was gone he was free and clear. He has had ct scans every 3-6 months and everything had looked good till today. He got his ct scan and they said his heart looked enlarged. he goes for ultra sound on monday. But we are just scared and wanting to know what happened to bring this on. Should we be worried. Our family has been through allot and we are just very scared at this point. The doctor told him not to worry lets just get the test done and go from there.
