What are the different types of kidney tumor?
Renal tumor is a swelling or lesion in the kidneys that occur due to abnormal cell growth. The kidney is a paired organ in the back or rear of the abdomen, which is responsible for urine production, blood filtration and reabsorption of the necessary water, salt and sugars back to the bloodstream, among other things. There are several types of kidney tumors that can be benign or malignant. If the tumor is benign, it is not cancer and does not metastasize or extends to other tissues and does not grow in an uncontrolled way. If the tumor is malignant, it deteriorates gradually by abnormal growth and spreading to other tissues with blood, lymph or direct invasion. Although kidney adenomas are small and benign, they are very similar to malignant cells of renal cell cancer (RCC) and are widely considered precancerous. As renal adenomas, renal oncocytomyjsou also considered precancerous, reminiscent of RCC cells under the microscope and usually do not contain any symptoms. Unlike kidney adenomas, renal oncocytoms for kidneyy unique and often become great. To avoid the development of cancer, doctors usually recommend surgical removal of kidney adenomas and renal oncocytomas if the patient's general health allows.
Angiomyolipoma, also called Renal Hamartoma, is a benign tumor resulting from a rare genetic mutation, which usually occurs in middle -aged women. Although it is not precancerous, large angiomyolipoma is potentially fatal if it bursts. If this renal tumor is large, it begins to grow or represents symptoms, doctors are likely to recommend surgical removal or procedure of arterial embolization.
Fibroma is another rare benign renal tumor, more common in women. This tumor is often asymptomatic, occurs to the edge and resembles malignant tumors. Because it is difficult to diagnose whether the tumor is malignant or benign, doctors often recommend surgical removal. Lipomas jsou also rare and more common in middle -aged women. This renal tumor affects the fat cells in the kidneys, it may represent symptoms of regional pain and blood in the urine and can be precancerous.
Malignant tumors most often result from cancer called renal cell cancer (RCC), which comes from the epithelium of the proximal tubule in the kidney nephron. Malignant types of renal tumors are classified based on the appearance of cancer cells under the microscope. Four specific types are carcinoma of renal cells of pure cells, papillary kidney cancer, renal cell carcinoma chromophobia, collection pipes. RCC, which do not correspond to the characteristics of these four types, are called non -classified kidney cancer. Surgical removal of the procedure known as a nephrectomy is recommended for all RCC types when tumoromed to the kidney.
Clear Cell RCC is by far the most predominant. The cells of these tumors appear pale or clean under the microscope. Papillary RCC shows projection similar to your finger fromCancer cells A are divided into two groups, type I and type II. Type II is more likely to metastasis. Chromophobe RCC cells resemble RCC with pure cells, but usually metastasize less than pure cell RCC. Pipe collection cancer is very rare, very aggressive and resembles papillary RCC.
Other types of malignant tumors include Wilms tumor, transient cell carcinoma and kidney sarcoma. Wilm's tumor, also known as nephroblastoma, is a relatively rare kidney tumor that affects small children. This renal tumor can spread to other tissues, but is highly treatable by methods such as surgery, chemotherapy and radiation.
transient cell carcinoma is kidney cancer, which comes from a renal pelvis, where the kidney articulates with urea. This kidney tumor is likely to be caused by cigarette smoking and is treated with nephrectomy, chemotherapy and radiation. Nephrectomy is the first line of treatment and usually includes surgical removal of the affected kidney, ureaand parts or whole bladder.
Renal sarcoma is a rare cancer that affects the connective tissue of the kidney. This kidney tumor may represent the symptoms of blood in the urine, tangible piece in the abdomen and lower back pain. If the kidney tumor is located and the patient can withstand surgery, doctors are likely to recommend nephrectomy. Chemotherapy and radiation can also be used.
