What are the preferred examination items for kidney cancer

What tests should be done if you have kidney cancer? Many patients with kidney cancer are diagnosed with kidney disease through some clinical manifestations. In fact, some instrumental examinations can also be used to diagnose whether you have kidney cancer. After confirming that you have kidney cancer, you should go to a regular kidney hospital for kidney treatment as soon as possible. So, what tests should be done if you have kidney cancer?

The method of diagnosing kidney cancer is to first determine whether the patient has kidney disease through some clinical manifestations. Kidney cancer can be divided into two types: familial and sporadic. The former has an early onset, multiple occurrences, and a bilateral tendency. About 2% to 4% of kidney cancer patients may suffer from bilateral kidney cancer at the same time or successively. The diagnostic criteria for kidney cancer are determined by clinical manifestations. Because the kidneys are located behind the peritoneum, there are no typical clinical manifestations in the early stages. The clinical manifestations are closely related to the size, growth location, and biological behavior of kidney cancer. The typical triad of the past (hematuria, pain, and lumps) is no longer an early clinical manifestation. If a kidney patient exhibits the triad, it indicates that the tumor has entered the late stage and is often likely to metastasize.

Some clinical manifestations of kidney cancer cannot completely determine whether a person has kidney cancer. Therefore, B-ultrasound or CT can be used to finally determine whether a person has kidney cancer. B-ultrasound: Generally used as the preferred diagnostic method, it has the advantages of being non-invasive, fast, simple, and cheap. The accuracy rate for diagnosing kidney cancer larger than 1 cm is more than 90%. It generally manifests as medium to low echoes, and sometimes there are strong echo calcifications at the edge or in the area of ​​the tumor. B-ultrasound is important for distinguishing solid and cystic masses from the kidneys, but complex cystic kidney cancer is sometimes difficult to distinguish from complex renal cysts.

In addition to using B-ultrasound for examination, CT can also be used to determine whether a person has kidney cancer. This method plays an important role and is currently a must-do examination in the diagnosis process. It can clearly show the size and range of the tumor, whether it has invaded adjacent tissues and organs, the renal vein, whether there are cancer thrombi in the vena cava, and whether there is lymph node metastasis. It is more accurate in the preoperative staging of kidney cancer. Enhanced CT can more clearly show tumor lesions than plain scans, and the degree of tumor enhancement is generally not as obvious as that of normal renal parenchyma. In short, typical clinical manifestations and imaging examinations are key methods for early detection of the disease.
