Kidney cancer
Can a color ultrasound detect renal cancer?
Color ultrasound is a diagnostic imaging method, and renal cancer is a malignant kidney tumor, which also has several stages with varying degrees of severity. For early-stage renal cancer, the cancerous characteristics are not pronounced, and at this time, performing a color ultrasound only serves as an indication and cannot confirm a diagnosis. In late-stage renal cancer, a color ultrasound might show more obvious signs or evidence indicative of a tumor, but it still cannot provide a definitive diagnosis. To confirm a diagnosis of renal cancer, a kidney biopsy or surgery is generally required. During surgery, a rapid frozen section biopsy can confirm the diagnosis. Preoperatively, to more accurately determine if the condition is renal cancer, an MRI or an enhanced CT scan might also be performed, as these tests provide more precise information than a color ultrasound.
Is kidney cancer prone to spreading?
The spread of cancer is caused by genes, and in the early stages of kidney cancer, it does not spread. If there is spreading, it indicates that the cancer has reached an advanced stage, and treatment becomes difficult at this time. If spreading occurs, the main goal is to control the disease and extend survival time, therefore, it is recommended that patients undergo biological treatment. Biological therapy can alleviate the clinical symptoms of late-stage tumor patients who have lost the opportunity for surgery, or where cancer cells have recurred or metastasized, and gradually helps to restore balance to the immune system. Normally, attention should be paid to a low-salt diet, eating light and vitamin-rich foods, and patients with severe edema and high blood pressure should avoid salt intake.
Postoperative care for radical nephrectomy
Postoperative care after radical nephrectomy for kidney cancer is crucial. While the patient is still unconscious from general anesthesia, comprehensive monitoring is essential, with close observation of vital signs including blood pressure, pulse, and respiration. Patients recovering from kidney cancer surgery are extremely vulnerable; thus, it is essential to scientifically and reasonably plan their diet based on their actual condition and physical constitution. A reasonable diet should be formulated, with no food allowed for 48 hours post-surgery. During the period when a gastric tube is in place, intravenous nutrition should be provided. Every activity post-surgery significantly impacts the recovery of the patient's condition, especially the first urination after surgery. Observing the timing and volume of urination is a crucial factor in determining the patient's condition.
What fruits can people with kidney cancer eat?
The diet of kidney cancer patients should ensure nutritional balance and should avoid spicy and stimulating foods, as well as foods that increase the metabolic burden on the kidneys. Currently, there are no reports indicating that eating fruit has a clear impact on tumor progression. This is because fruits primarily contain large amounts of water, sugar, vitamins, and trace elements, which are essential substances for normal human body functions. Vitamin C has a positive effect on body immunity, so consuming more fruits can be beneficial for health. Kidney cancer patients should increase their protein intake to compensate for the depletion caused by cancer. Here, I recommend a concept of prolonging life with illness, and everyone can search for more information on it.
Is kidney cancer contagious?
Kidney cancer is not contagious; most kidney cancers originate from malignant tumors caused by renal tubular epithelial cells. The clinical symptoms of this type of kidney cancer mainly include hematuria and abdominal masses, which may also affect kidney function. Kidney cancer is mostly not associated with any pathogens, such as bacteria or viruses, hence there are no infectious causes for kidney cancer. Currently, the medical community does not have a clear understanding of the causes, which may be related to unhealthy lifestyle habits such as smoking, as well as genetic factors, obesity, hypertension, heavy metal poisoning, and other reasons. Since there are no pathogens involved, there is no contagion.
Can color Doppler ultrasound detect renal cancer?
As an imaging examination method, color Doppler ultrasound can examine the kidneys and detect signs of kidney diseases, including kidney cancer, but it cannot serve as a definitive basis for diagnosing kidney cancer. Color Doppler ultrasound observes the size, shape, structure, and other medical information of the examined organ. From this information, some clues indicating kidney cancer can be found. However, to confirm kidney cancer, a pathological diagnosis is often required. Pathological diagnosis involves performing a kidney biopsy or surgically removing a part of the kidney tissue for pathological examination to definitively determine the presence of kidney cancer. Thus, color Doppler ultrasound can only serve as a clue in the investigation of kidney cancer.
What is good to eat for kidney cancer?
What is good to eat for kidney cancer, the diet of kidney cancer patients should pay attention to ensuring balanced nutrition intake, you can eat more fruits and vegetables, such as spinach, rape, apples, pears, persimmons, cherries and other common fruits, as well as oranges and tangerines are all fine. It is important to avoid eating fried foods, barbecues, quit smoking, stop drinking, do not eat seafood, do not eat overnight meals, avoid smoky environments, and the cooking of food should focus on being finely made and soft. You can try to minimize cooking steps such as frying and grilling, and primarily use slow stewing and steaming.
Complications after interventional treatment for renal cancer
Post-intervention complications of renal cancer can include hematuria, lower back pain, and tumor recurrence. Hematuria is indirect and painless, visible to the naked eye. Renal cancer often accompanies renal colic, which is due to the formation of ureteral blood clots. Blood clots from renal cell carcinoma can form a ribbon-like shape through the ureter, and the degree of hematuria is not related to the size of the renal cell carcinoma. Renal cell carcinoma sometimes presents persistent microscopic hematuria. Lower back pain is a common symptom, often an intermittent dull pain, usually due to the enlargement of the kidney tumor. When the tumor invades surrounding organs and the psoas major muscle, the pain is heavy and persistent.
Are renal cell carcinoma and kidney cancer the same thing?
Kidney cancer is one of the types included in the simplified classification of renal tumors. Generally, kidney cancer includes renal cell carcinoma, renal adenoma, adrenal adenoma, and papillary cystadenocarcinoma, which are commonly encompassed within the scope of kidney cancer. Simply put, kidney cancer is a category in clinical diagnostic examinations. Renal cell carcinoma belongs to the pathological classification of renal tumors, and typically includes conventional types of renal cell carcinoma, such as the commonly mentioned clear cell carcinoma, which is the most common type. Additionally, chromophobe renal cell carcinoma and collecting duct carcinoma are also types of renal cell carcinoma.
Is kidney cancer the same as uremia?
Kidney cancer cannot be equated with uremia. Kidney cancer is a malignant tumor of the kidney. Its treatment can be through surgery, radiotherapy, chemotherapy, and so on. Uremia, on the other hand, is the end-stage development of various kidney diseases. It is a clinical syndrome characterized by the loss of most or all kidney function, leading to sodium and water retention, various electrolyte disorders, and the accumulation of toxins such as urea nitrogen and creatinine. The treatment of uremia relies on hemodialysis, peritoneal dialysis, or kidney transplantation. Although kidney cancer is not uremia, severe kidney cancer can also develop into uremia. At that time, blood replacement therapy is also needed.
