Symptoms of Kidney Cancer: A Guide to Early Detection

Kidney cancer is a global health concern across the world. Kidney cancer, popularly known as renal cancer or renal cell carcinoma. However, early detection is crucial for controlling and further managing the cancer growth in the kidney to get successful treatment and better outcomes in patients. If you are concerned about this type of cancer or experiencing any symptoms of kidney cancer, then read further!
In this article, we’ll discover more about the causes of cancer and how early detection can cure this type of cancer.
What is kidney cancer?
Kidney cancer is a type of cancer where there is an abnormal growth of cells in the kidney tissue. In time, these cancer cells form a mass called a tumor in the kidney. The cancer often begins when something triggers a change in the cells, which makes them multiply and divide out of control.
The two primary types are
Renal cell carcinoma:
This is the most common type of cancer, accounting for 80% of all cancer cases in the kidney.
Urothelial carcinoma:
This type of cancer originates in the urothelial cells, which line the urinary tract, including the urinary bladder, ureters, and urethra.
When a cancerous or malignant tumor starts to spread to other parts of the body, tissues, and organs, it's called metastatic kidney cancer. This is an advanced stage of cancer.
Symptoms of Kidney cancer
Kidney cancer might not show any noticeable symptoms in its early stages. Because of this reason, this cancer is often difficult to detect in its initial stages.
Here are some of the common symptoms of this cancer:
These may include:
- Blood in your urine (Hematuria)
- A lump or mass in the kidney area
- Fatigue or weakness
- Experiencing weight loss
- Bone pain
- High blood pressure
- Anemia
- Loss of appetite
- Flank pain
How can kidney cancer be detected early?
In the majority of cases, cancer formed in the kidney is not diagnosed until it reaches its advanced stage. This usually happens when cancer starts to grow without causing any serious or noticeable symptoms. It’s often difficult to detect the initial stages or small kidney tumors during the physical examination.
However, a urine analysis can most of the time detect traces of blood's presence in the urine, which is often considered the major symptom of cancer in the kidney. If you are someone who is at high risk of developing this cancer, regularly performing a urine analysis is crucial.
Primary causes of kidney cancer
The exact cause of developing this type of cancer in the kidney is not clear yet. However, there are some risk factors that might increase the risk of developing this cancer in people.
These may include:
- Smoking: People who have smoking habits are at greater risk of developing this cancer.
- Obesity: This is another risk factor for developing this cancer. In general, the more overweight the person. They are more likely to get this cancer.
- Family history of cancer: People who have a family history of cancer in the kidney might have an increased chance of developing this cancer.
- High blood pressure: People with high blood pressure rates are at a risk of developing this cancer.
- Gene changes or mutations: A gene contains certain instructions on how to function as a cell. Any changes in certain genes might increase the risk of developing this cancer.
- Long term dialysis treatment: Kidney dialysis is the process of cleaning your blood by passing it through a special machine.
- Tuberous sclerosis complex: Tuberous sclerosis is a disease that often causes seizures and some intellectual disabilities in people.
- Von Hippel- Lindau complex: People with this type of inherited disorder are at great risk of developing cancer in the kidney.
There are some other risk factors that also cause this type of cancer in people.
These may include:
- Cowden syndrome
- Birt-Hogg-Dube syndrome (BHD)
- Exposure to chemicals
- Advanced kidney diseases
Treatments
The treatment of this cancer majorly depends on the stage and growth of the tumor, along with individual medical conditions, age, and gender. The treatment approaches include surgery, ablation, radiation therapy, targeted therapy, immunotherapy, and, in some cases, chemotherapy.
Surgery:
Cancer surgery is a treatment approach used for most cases of cancer in the kidney. There are several surgical options used to treat this kind of cancer. These may include:
- Partial nephrectomy: In this surgical procedure, the surgeon might remove the part of your kidney that contains the tumor.
- Radical nephrectomy: In this procedure, your surgeon might remove the entire kidney and some sort of tissue around it. They might also remove some lymph nodes in that area.
If any patient’s one kidney gets removed, then the remaining kidney is usually able to perform the function of both kidneys.
Ablation:
This is an alternative surgery used for the treatment of this cancer. During this therapy, the doctor might insert a needle-shaped device through your skin to the kidney. This device would send hot or cold waves to destroy the cancer cells. This therapy destroys the abnormal cells (ablates). This therapy often leads to the cancer cells' death. However, it won’t harm any healthy cells.
Radiation therapy:
Radiation therapy is often recommended for patients when they have only one kidney that is functional or surgery can’t be performed on those patients. Radiation therapy is most commonly used to reduce the pain or discomfort in patients.
Targeted Drug therapy:
The targeted drug therapy usually blocks the certain features that help cancer cells grow. For example, these drugs mostly stop the growth of new blood vessels or proteins that feed cancer.
Immunotherapy:
Immunotherapy is another treatment approach used to boost the patient’s immune system. In turn, this treatment often helps your body to recognize and destroy cancer cells more effectively than ever. Immunotherapy can sometimes be given as a standalone treatment or performed along with the surgery.
Chemotherapy:
Chemotherapy is mostly used to treat cancer in the kidneys. However, this is not the standard treatment approach used for the cure of this type of cancer. Chemotherapy is often performed after immunotherapy and targeted drug therapy. These medications are taken through the mouth or vein (intravenously) and are mostly well tolerated by the patients.
How can you prevent kidney cancer?
However, kidney cancer is not always preventable; meanwhile, adopting certain healthy lifestyle choices significantly reduces the risk of the cancer’s growth in people. For example, quitting smoking and stopping excessive alcohol consumption are considered effective ways to reduce the chance of this cancer formation in the kidneys.
Managing a healthy weight with regular physical exercise and a balanced diet helps with preventing obesity, which is also associated with this cancer. For people with hypertension and high blood pressure, a balanced diet, medication, a healthy diet, and regular physical activity might be crucial.
Additionally, if you have a family history of cancer, then getting regular tests and limiting the exposure to chemicals can also reduce the risk.

Frequently Asked Questions
The exact cause of kidney cancer is not clear yet. There isn’t any way to prevent kidney cancer completely. However, you can control or reduce the risk of this cancer by not smoking and managing certain lifestyle habits, such as avoiding excessive alcohol consumption and managing health issues like high blood pressure, diabetes, and obesity.
Here are some of the symptoms of kidney cancer, these may include:
- Experiencing blood in your urine (Hematuria)
- A lump or mass in your kidney area
- Loss of appetite
- Experiencing weight loss
- Bone pain
- High blood pressure
- Anemia
- High calcium
- Experiencing fatigue or tiredness, weakness
There are some tests that show any early symptoms of kidney cancer. For example, a regular urine test might find any traces of blood that can’t be seen by the naked eye. There are some kidney cancers detected through CT scan. MRI scans produce the image details of kidneys as well. Additionally, ultrasound is also used to identify the early signs of cancer in the kidneys.
Kidney treatment options mainly depend on the stage and growth of the tumor. Treatment options include surgery, ablation, radiation therapy, targeted therapy, immunotherapy, and in some cases, chemotherapy might also be used.
