How serious is a tumor on the kidney?

It varies. Benign kidney tumors are those that are not malignant. These tumors don’t spread to other areas of your body and are often smaller than malignant ones. The most popular method of treating kidney tumors that are not malignant is surgery.

In order to prevent problems, you should begin treatment as soon as possible, regardless of the type of kidney tumor you have.

How can renal carcinoma be identified?

Your healthcare practitioner will do a thorough medical history and physical examination if you are experiencing signs of kidney cancer. Additionally, they could request specific tests that aid in the detection and evaluation of malignancy. These examinations might consist of:

Urinalysis: A sample of your pee, or urine, is examined to check for the presence of blood. Urine sample testing can identify minuscule amounts of blood, undetectable to the human eye.

Blood tests: These measure the quantity of each kind of blood cell and examine the various electrolytes in your body. A blood test can determine if you have anemia, or too few red blood cells, or whether you have compromised kidney function, as indicated by elevated creatinine levels.

A CT scan is a type of X-ray in which a sequence of pictures, or slices, of your inside anatomy are produced by a computer. Intravenous dye (contrast) is frequently used for this examination. Dye-impaired individuals might not be able to absorb the dye.

A big magnet, radio waves, and a computer are used in magnetic resonance imaging (MRI) to create images of the inside of your body.

Ultrasound: This examination creates pictures on a monitor by passing high-frequency sound waves through bodily tissues. Tumors differ in density from normal tissues, which makes this test useful for identifying them.

Renal mass biopsy: A little sample of your tissue is taken (biopsy) and a thin needle is put into the tumor during this operation. Under a microscope, a pathologist will examine the tissue to check for cancerous cells. Your healthcare practitioner may or may not suggest this test based on the unreliability of biopsies for kidney cancer.

What stages exist for kidney cancer?

The majority of malignancies are categorized according to their stage, which helps with treatment planning. A cancer’s stage is determined by:

the tumor’s size and placement.

The degree of infection in your lymph nodes.

how far the cancer expanded to other tissues and organs, if it did so at all.

To ascertain the cancer’s stage, your healthcare professional analyzes data from a variety of procedures, such as CT, MRI, and biopsy.

Stage I: The tumor is limited to your kidney and is no more than seven centimeters (cm) in diameter. Neither lymph nodes nor other tissue have been affected. Lymph nodes are tiny “filters” that hold on to cells that fight infections while capturing pathogens and cancerous cells.

Stage II: The tumor is still only in your kidney, but it is more than 7 cm broad. Neither lymph nodes nor other tissue have been affected.

Stage III: The tumor has progressed to the surrounding tissue of your kidney, adjacent lymph nodes, and your major blood arteries, the renal vein and inferior vena cava.

Stage IV: The tumor has progressed to distant lymph nodes or other organs, as well as the adrenal gland, the little gland that lies atop your kidney.

Additionally, tumors can be graded according to the appearance of aberrant cells in the tumor. Your healthcare professional can also learn the tumor’s expected growth rate from the tumor grade. High-grade tumors are defined as tumors whose cells proliferate quickly and don’t resemble normal cells. Compared to low-grade tumors, high-grade tumors often develop and spread more quickly.

How does renal cancer get treated?

The course of treatment for kidney cancer is determined by the tumor’s grade and stage, your age, and your general health. Options include targeted medication therapy, radiation therapy, immunotherapy, surgery, ablation, and occasionally chemotherapy.


The most common course of treatment for kidney cancer is surgery. There are other surgical alternatives to think about, such as:

Partial nephrectomy: The tumor-containing portion of your kidney is removed by your surgeon.

A radical nephrectomy involves the removal of your kidney along with some surrounding tissue by your surgeon. Additionally, they could remove a few local lymph nodes.

The kidney that is left generally has enough function to carry out the functions of both kidneys after one is removed.


Heat and cold can occasionally kill cancer cells. Cryoablation or radiofrequency ablation may be beneficial for those who are not candidates for surgery.

Cryoablation: A needle is inserted through your skin and into the kidney tumor during this treatment. After that, cold gas is used to freeze the cancer cells.

Radiofrequency ablation: A needle is inserted under your skin and into the kidney tumor by your healthcare practitioner. The cancer cells are then destroyed by passing an electrical current across them.
