When the cells in your kidneys grow and alter uncontrollably, kidney cancer can result. Symptoms of kidney cancer include blood in the urine, elevated blood pressure, and flank discomfort. Radiation therapy, chemotherapy, and surgery are among the therapies for kidney cancer. Like with all malignancies, effective treatment depends on early discovery.

What is cancer of the kidneys?

The abnormal proliferation of cells in your kidney tissue is known as kidney cancer. A tumor is a mass that develops from these cells over time. When a change in the cells occurs and they start to divide uncontrollably, cancer starts.

A malignant tumor has the potential to spread to other tissues and important organs. This process is known as metastasis.

Who is affected by kidney cancer?

The age range of 65 to 74 is when kidney cancer most frequently affects individuals. The condition is twice as likely to affect males as women. It is also more prevalent in Black and Native American communities.

In youngsters, kidney cancer is far less prevalent. Nonetheless, every year in the US, between 500 and 600 children receive a diagnosis of a Wilms tumor, a kind of kidney cancer.

What kinds of kidney cancer exist?

Kidney cancer comes in a variety of forms, including:

Renal cell carcinoma (RCC): Making over 85% of all kidney cancer cases, RCC is the most prevalent kind in adults. Though it can affect both kidneys, renal cell carcinoma often begins as a solitary tumor in one of them. The kidney’s tubules, which are microscopic tubes that replenish your blood with nutrients and hydration, are where the cancer starts. Clear cell renal cell carcinoma is the most prevalent kind of RCC (ccRCC).

Transitional cell carcinoma: Between 6% and 7% of kidney malignancies are transitional cell carcinomas. Usually, this cancer starts where your ureter joins the major portion of your kidney. Your renal pelvis is the term for this region. Urine or bladder cancer is another possible site for transitional cell carcinoma.

Renal sarcoma: Making up only 1% of cases, renal sarcoma is the least frequent kind of kidney cancer. If left untreated, it can spread to surrounding organs and bones from its starting point in the connective tissues of your kidneys.

The most prevalent kind of kidney cancer in children is wilms tumor. Roughly 5 percent of kidney malignancies are caused by it.

How often does kidney cancer occur?

In the US, kidney cancer accounts for around 3.7% of all cancer cases. Kidney cancer is detected in around 62,000 Americans each year. As people age, their chance of kidney cancer rises.

What symptoms indicate kidney cancer?

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

Symptoms of kidney carcinoma might include:

Urine with blood in it (hematuria).

a tumor or lump around your kidneys.

Pain on the flank.


an overall feeling of being unwell.

appetite decline.

Reduced weight.

Fever of low grade.

bone aches.

elevated blood pressure.


elevated calcium.

What is kidney cancer’s main cause?

Although the precise etiology of kidney cancer is unknown, there are several risk factors that may make the condition more likely to develop. Among them are:

Smoking: The risk of kidney cancer is higher among smokers. Furthermore, the danger increases with the length of time a smoker smokes.

Obesity: Kidney cancer is associated with obesity. Generally speaking, the risk increases with an individual’s level of overweight.

High blood pressure, often known as hypertension, has been connected to a higher risk of kidney cancer.

Family history: Those who have kidney cancer in their family may be more likely to have the disease themselves.

Radiation therapy: There may be a small increased risk of kidney cancer in women who have had radiation treatment for cancer of the reproductive organs.

Mutations in genes: Instructions for a cell’s operation are encoded in genes. Kidney cancer risk may rise due to changes in certain genes.

Dialysis is a long-term therapy that involves purifying your blood with a specialized machine. When a person’s kidneys aren’t working well, dialysis is employed.

Complex tuberculosis: Tuberculosis is a disease that results in tumor growth in several organs, convulsions, and intellectual impairments.

Kidney cancer is more common in people with von Hippel-Lindau disease (VHL), a genetic illness. Non-cancerous tumors in blood arteries, usually in the brain and eyes, are caused by this condition.
