A common symptom of kidney cancer is painless visible blood in urine, which is also the primary initial symptom. It is intermittent and sometimes accompanied by blood clots. However, after exhibiting this symptom, how long a patient can live depends on individual constitution and the severity of the condition. Once discovered, early surgical treatment is recommended, followed by immunotherapy, such as using interferons and interleukins.

Is kidney cancer prone to metastasis?

Kidney cancer in its early stages generally does not metastasize. If it does metastasize, it usually follows several paths: one is hematogenous or lymphatic spread, followed by local diffusion, and then the tumor invades surrounding fat or blood vessels, which is local diffusion. It is also important to note that there is a pseudo-capsule around the kidney cancer that prevents the spread of cancer cells. Metastasis is not likely when the tumor is small, but as the tumor size increases or in some special types of tumor cells, metastasis may occur.

Is stage II kidney cancer considered early stage?

The staging of kidney cancer is primarily based on the size of the tumor, whether there is lymph node metastasis, involvement of adjacent organs or lymphatic vessels, and metastasis to distant organs. The TNM staging system is commonly used in clinical settings to stage kidney cancer, where "T" represents the depth of tumor invasion, "N" represents the status of lymph node metastasis, and "M" represents distant metastasis. Stage II refers to a tumor with a maximum diameter greater than seven centimeters but confined to the kidney. Stage II is further divided into stage IIA and stage IIB. Stage IIA refers to a tumor with a maximum diameter greater than seven centimeters but less than ten centimeters, confined to the kidney. Stage IIB refers to a tumor with a maximum diameter greater than ten centimeters, but still confined to the kidney. In the case of stage II kidney cancer, although it is an early stage, curative treatment can be achieved through surgery. Therefore, if diagnosed with stage II kidney cancer, it is vital to pursue aggressive treatment.

Is late-stage kidney cancer contagious?

Advanced kidney cancer is not contagious from person to person. Kidney cancer is when the tissues of the kidney undergo abnormal proliferation and the condition has advanced to a late stage. Generally, it is recommended that patients with kidney cancer follow a high-protein, low-salt, low-sugar diet, avoid foods that increase the metabolic burden on the kidneys, and focus on fine, refined, and soft foods to improve the efficiency of nutrient absorption. Patients can eat more fruits and vegetables to increase their intake of vitamins and fibers. It is also generally advised for patients to eat more garlic, avoid eating leftovers, overnight foods, pickled items, abstain from alcohol, especially strong spirits, and avoid smoking.

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.

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.
