Kidney Cancer

Kidney cancer: what is it?

The aberrant proliferation of cells in your kidney tissue is known as kidney cancer. These cells eventually combine to create a mass known as a tumor. Cancer starts when an alteration in the cells causesdc them to divide uncontrollably.

It is possible for a malignant or cancerous tumor to spread to other tissues and important organs. This is dknown as metastasis when it occurs.

Who is affected by kidney cancer?

The most prevalent age group for kidney cancer is 65–74 years old. 

What kinds of kidney cancer are there?

Kidney cancer comes in several forms, such as:dxx

Renal cell carcinoma (RCC): RCC makes about 85% of all kidney malignancies and is the most prevalent kind in adults. Although it may affect both kidneys, renal cell carcinoma often appears as a single tumor in one kidney. The cells lining your kidney’s tubules—tiny tubes that return fluid and nutrients to your blood—are where the cancer starts. Clear cell renal cell carcinoma (ccRCC) is the most prevalent kind of RCC.

Transitional cell cancer (TCC) : Between 6 and 7 percent of kidney tumors are transitional cell carcinomas. The location where your ureter joins the main portion of your kidney is often where this cancer starts. Your renal pelvis is the name given to this region. Additionally, your bladder or ureters may develop transitional cell cancer.

Renal Sarcoma : Just 1% of kidney cancer cases are renal sarcoma, making it the least frequent kind of the disease. Your kidneys’ connective tissues are where it starts, and if left untreated, it may spread to other organs and bones.

Wilms Tumor : The most prevalent kind of kidney cancer in children is called a Wilms tumor. About 5% of kidney malignancies are caused by it.

Causes and Symptoms

What symptoms indicate kidney cancer?

In its early stages, kidney cancer may not show any signs at all. However, symptoms could start to show up as the tumor becomes bigger. Because of this, kidney cancer often goes undetected until it has started to spread.

Symptoms of kidney cancer might include: 

• Hematuria, or blood in the urine.
• a tumor or lump around your kidneys.
• Pain in the flank.
• fatigue.
• an overall sensation of being unwell.
• appetite loss.
• reduction of weight.

low-grade fever.

• bone ache.
• elevated blood pressure.
• anemia.
• elevated calcium levels.

What is kidney cancer’s main cause?

Although the precise etiology of kidney cancer is unknown, there are certain risk factors that might make the condition more likely to strike you. These consist of:

• Smoking: Individuals who smoke are more likely to get kidney cancer. Additionally, the risk increases with the length of time a person smokes.
• Obesity: Kidney cancer risk factors include obesity. Generally speaking, the risk increases with an individual’s level of weight.
• Hypertension, another name for high blood pressure, has been linked to a higher risk of kidney cancer.
• Family history: Individuals who have kidney cancer in their family may be at higher risk of getting the disease themselves.
• Radiation therapy: Women who have had radiation treatment for reproductive organ cancer may be somewhat more susceptible to kidney cancer.
• Mutations in genes: Instructions for a cell’s operation are encoded in genes. Kidney cancer risk may rise as a result of genetic alterations.
• Dialysis for a long time: The procedure of cleansing your blood by running it through a specialized machine is called dialysis. When a person’s kidneys aren’t working correctly, dialysis is utilized.
• Complex of tuberous sclerosis: In addition to causing tumors in several organs, tuberous sclerosis also causes convulsions and intellectual deficits.
• VHL, or von Hippel-Lindau disease: Kidney cancer is more likely to strike those who have this hereditary condition. This condition results in blood vessel tumors that are not malignant, usually seen in the brain and eyes.

What is the severity of a kidney tumor?

• It varies. Certain kidney tumors are benign, meaning they are not malignant. These tumors often don’t spread to other regions of your body and are smaller than malignant ones. The most popular therapy for kidney tumors that are not malignant is surgical excision.

To prevent problems, you should begin treatment as soon as possible, regardless of whether your kidney tumor is malignant or not.

Testing and Diagnosis

How can kidney cancer be identified?

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

• Urinalysis: A urine sample is examined to see if blood is present. Urine sample testing may identify even minute amounts of blood that are undetectable to the human eye.
• Blood testing: These tests measure the quantity of each kind of blood cell and examine the various electrolytes in your body. Anemia, or low red blood cell count, and renal impairment, as shown by creatinine, may both be detected by a blood test.
• A CT scan is a kind of X-ray that creates a number of pictures, or slices, of the interior of your body using a computer. Intravenous contrast (dye) is often used for this examination. The dye may not be able to be administered to those with compromised renal function.

• MRI – A big magnet, radio waves, and a computer are used in magnetic resonance imaging (MRI), a procedure that creates pictures of the interior of your body.
• Ultrasound: This test produces pictures that are seen on a monitor by using high-frequency sound waves that travel through bodily tissues. Because tumors vary in density from healthy tissues, this test is useful in identifying them.
• Renal mass biopsy: In this process, a little sample of your tissue is taken (biopsy) by inserting a thin needle into the tumor. To check for cancer cells, a pathologist will examine the tissue under a microscope. Because kidney cancer biopsies aren’t always 100% accurate, your doctor may or might not suggest this test.

Staging of kidney cancer?

The majority of malignancies are categorized by stage, which helps with treatment planning. The location and size of the tumor determine the cancer’s stage.

the degree of damage to your lymph nodes.

the extent to which other tissue and organs were affected by the malignancy, if at all.

To ascertain the stage of cancer, your healthcare professional examines data from a number of tests, such as CT, MRI, and biopsy.

Stage I: The tumor is limited to your kidney and is 7 cm wide or less. No lymph nodes or other tissue have been affected. (Lymph nodes are tiny “filters” that hold infection-fighting cells and capture bacteria and cancer cells.

Stage II: The tumor still solely exists in your kidney, but it is more than 7 cm broad. No lymph nodes or other tissue have been affected.

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

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

Additionally, tumors are graded, which assigns a number to a tumor according to the appearance of its aberrant cells. Your healthcare professional may also learn how quickly the tumor is expected to develop by using tumor grading. High-grade cancers are those whose cells proliferate quickly and don’t resemble normal cells. Compared to low-grade tumors, high-grade tumors often develop and spread more rapidly.

Handling and Therapy

What is the treatment for kidney cancer?

Treatment for kidney cancer is determined by the tumor’s grade and stage, your age, and your general health. Surgery, ablation, radiation treatment, immunotherapy, targeted medication therapy, and sometimes chemotherapy are among the available options.

• Operation

For the majority of kidney cancer stages, surgery is the preferred course of therapy. A number of surgical alternatives might be taken into account, such as:

With a partial nephrectomy, the tumor-containing portion of your kidney is removed by the surgeon.

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

The remaining kidney may often carry out the functions of both kidneys after one is removed.

• Ablation

Cancer cells may sometimes be destroyed by heat and cold. Radiofrequency ablation or cryoablation may be beneficial for patients who are not candidates for surgery.

A needle is inserted through your skin and into the kidney tumor by your healthcare professional during the cryoablation treatment. After that, cold gas is used to freeze the cancer cells.

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

• Radiation treatment

If you just have one kidney or are not a candidate for surgery, your doctor could suggest radiation treatment. The most common application of radiation treatment is to reduce pain and other symptoms of kidney cancer.

• Targeted therapy

Targeted medication treatment inhibits certain traits that support the growth of cancer cells. These medications, for instance, may prevent the development of new blood vessels or proteins that support cancer.

When surgery is not a possibility, targeted medication treatment is often used. To lower the chance of cancer returning, these drugs may sometimes be administered after surgery.

• Immunotherapy

Immunotherapy strengthens your own immune system by using certain drugs. As a result, your body is better able to identify and eliminate cancer cells. Immunotherapy may be administered alone or in conjunction with surgery.

• Chemotherapy

Kidney cancer is not often treated with chemotherapy. However, it may be useful in some situations, generally only after immunotherapy and targeted medication treatment have been tried. Chemotherapy drugs are usually well tolerated and may be administered orally or intravenously.
