hmmmm. people here seem to be so quick to jump the gun and go directly from making an assessment of a patients current health problem and go directly to suggesting interventions. From a medical standpoint treatment depends on the type, location, stage/ of growth if in fact it is a tumor, or could be something unrelated, these all depend on different types of scans, CT, abdominal ultrasound, biopsy etc. I am guessing he went directly tothe ER, they then did a scan or sent him to a room on a medical/surgical floor of a hospital, where over a day or two saw a few consulting physicians and various tests. ON the medical surgical floor he probably had urine specimen analysis, bloodwork w/ emphasis on BUN ,creatinine, glomerular filtration uric acid, general CBC metabolic panel, Chems on several occations. His urine was monitored by nursing, pain level, was put on strict I&O monitoring. Believe me there is more than saying to "no sugar, pop, salt, tumors thrive on sugar, drink lots of water" I understand the interventions they did state are valid in certain situations, but the best thing you can do is talk to the registered nurses and the physician when they do the rounds and are in your fathers hospital rooms. dont be afraid to ask the registered nurse who is taking care of your father on his/her shift on the rationale for why certain measures are being taken. ie...why is his uring output being monitored, when is he going for his next scan, why type of IV is running, why is a certain medication ordered. why is he being woke up every 4 hours for vital signs. I understand hospitalization of a family member can be very stressfull for your father, as well for yourself when you do not have a definitive diagnosis and expectations.
