The prognosis of renal cancer is closely related to its clinical staging. If it is in the early stages, surgery is the preferred treatment and the prognosis is very good. Timely surgery followed by subsequent treatments such as immunotherapy, targeted therapy, etc., is recommended. For early-stage renal cancer, the five-year survival rate after surgical removal can exceed 90%, and some patients may live without issues for over 20 years. How long someone lives specifically also depends on the individual's constitution and physical condition.

The difference between benign and malignant kidney cancer.

The incidence of kidney cancer is also considered relatively high, with over 95% of kidney tumors being malignant, and benign tumors being less common. The distinction between benign and malignant tumors is determined by their symptomatic expression and growth patterns, and they have different impacts on the body. Generally, benign tumors grow expansively or exophytically, have a slower growth rate, and have clearer boundaries with often a capsule surrounding them. The texture and color of the tumor are close to that of normal tissues. Malignant tumors, on the other hand, exhibit the opposite characteristics.

Can kidney cancer be diagnosed with a CT scan?

If you have kidney cancer, preoperative examinations, including ultrasound, CT, and even MRI, cannot definitively diagnose the cancer. These preoperative tests primarily provide diagnostic references. To confirm a diagnosis of kidney cancer, a biopsy via renal tumor puncture must be performed, or after surgery, the specimen should be sent for pathological examination to be definitively diagnosed based on the pathology results. This is because the pathology results clarify the type of tumor cells and their grading, making the pathological examination the final and most accurate diagnostic result.

Does kidney cancer affect the renal calyx?

Kidney cancer lesions can sometimes affect the renal calyces. This is because kidney cancer is a malignant disease characterized by invasion and metastasis. When the lesions from kidney cancer invade the surrounding renal tissues, this can impact the function of the renal calyces. Some patients may experience toxic side effects from chemotherapy, targeted therapy, and other related antitumor treatments for kidney cancer, which can also affect the renal calyces. In summary, the lesions from kidney cancer and related antitumor treatments can potentially affect and even lead to clinical manifestations of kidney damage, including complications such as hydronephrosis. Once the kidney cancer lesions affect the renal calyces, this can result in sequelae such as renal failure.

Can kidney cancer patients be contagious?

Kidney cancer is not an infectious disease, so it is not contagious. Kidney cancer actually occurs when carcinogenic changes happen in the epithelial cells of the renal tubules, leading to the formation of masses and blood in the urine within the kidneys, and can even cause kidney failure. Moreover, kidney cancer carries a certain risk of metastasis, potentially causing damage to other organs. This disease is not contagious. The so-called infectiousness of a disease is due to the presence of pathogens that can cause infection. For example, hepatitis B can be transmitted because carriers have the hepatitis B virus in their bodies. Kidney cancer, however, does not involve viruses, bacteria, or fungi, so it is not infectious.

Dietary precautions for renal cancer

Kidney cancer patients should be cautious with their diet and there are three types of food they should absolutely avoid: First, foods high in salt. Kidney cancer patients often suffer from severe kidney dysfunction, leading to edema. Consuming salty foods can increase the body's sodium content, causing sodium retention which is not metabolized in time, exacerbating the swelling. Second, high-fat foods. Excessive fat can also lead to weight gain, and high body fat can burden the kidneys. Third, foods high in potassium. With kidney cancer, patients often have inadequate kidney function and produce less urine, leading to high levels of potassium in the body. Consuming foods high in potassium can further increase blood potassium levels. Therefore, it's advisable for kidney cancer patients to avoid fruits and vegetables high in potassium.
