Cancer of the kidney was a dreadful disease in the past because usually patients use to present in late stages with advanced disease. In the present time most of kidney cancer are incidentally detected during ultrasound or other imaging studies done for unrelated problems. The other presenting symptoms of kidney cancer are pain in the flanks, blood in urine, a palpable mass. A contrast CT scan is required for confirming doubts about the presence of tumor. Surgery is the only realistic treatment of this disease. With the advancement of technology, these tumors can be dealt with minimally-invasive surgeries or in-common parlance key hole surgeries. The hospital stay can be as short as one day only and people can resume their normal work in three to five days time.
If the tumor is very small then sometimes it is possible to remove only the tumor and the kidney can be saved. The results of this surgery are comparable to removing the entire kidney. In this surgery also hospital stay is short and recovery is fast.
