Kidney cancer, also known as renal cell carcinoma, is a serious medical condition that affects thousands of individuals worldwide. It is essential to understand this disease, as early detection and appropriate treatment are critical for achieving positive outcomes.
In this article we will help you to know about the diagnosis and treatment in detail. Without further ado, lets get started!
What is Kidney Cancer?
Kidney cancer, medically known as renal cell carcinoma is a type of cancer that originates in the kidneys. The kidneys are vital organs responsible for filtering blood, removing waste products, and producing urine. When cells in the kidneys undergo uncontrollable and abnormal growth, they form a mass or tumor, which can be benign (non-cancerous) or malignant (cancerous).
Malignant kidney tumors have the potential to spread to other parts of the body through the bloodstream or lymphatic system, leading to secondary tumors in distant organs. Kidney cancer can be categorized into several subtypes, with renal cell carcinoma being the most common type, accounting for approximately 90% of all kidney cancer cases.
Causes of kidney cancer:
The exact cause of kidney cancer is often unknown, but certain risk factors can increase the likelihood of its development. Some of these risk factors include:
Age:
Kidney cancer is more prevalent in people over the age of 40, and the risk increases with age.
Smoking:
Cigarette smoking is a significant risk factor for kidney cancer.
Obesity:
Being overweight or obese increases the risk of developing kidney cancer.
Hypertension (high blood pressure):
Chronic high blood pressure is associated with an increased risk of kidney cancer.
Family history:
If a person has a family history of kidney cancer, they may have a higher risk of developing the disease themselves.
Certain genetic conditions:
Inherited genetic disorders such as von Hippel-Lindau (VHL) syndrome, hereditary papillary renal cell carcinoma (HPRCC), and others can predispose individuals to kidney cancer.
What are the signs of kidney cancer in adults?
Symptoms of kidney cancer:
Symptoms of kidney cancer may not be evident in the early stages, but as the tumor grows, common signs and symptoms can include:
- Blood in the urine (hematuria)
- Persistent pain in the side or lower back
- A palpable mass or lump in the abdomen or side
- Unexplained weight loss
- Fatigue
- Fever
- Anemia
Diagnosis for kidney cancer:
Diagnosing kidney cancer involves a series of tests and procedures to identify the presence of a tumor and determine its characteristics. Here are five common methods used for the diagnosis of kidney cancer:
Imaging Tests:
Imaging plays a crucial role in detecting kidney tumors and evaluating their size, location, and extent. Common imaging tests include:
Computed Tomography (CT) Scan:
A CT scan combines X-rays and computer technology to create detailed cross-sectional images of the kidneys, allowing doctors to visualize any abnormalities.
Magnetic Resonance Imaging (MRI):
An MRI uses powerful magnets and radio waves to produce detailed images of the kidneys, providing a more comprehensive view of the tumor and nearby structures.
Ultrasound:
A non-invasive procedure that uses sound waves to create images of the kidneys and detect the presence of a tumor.
Biopsy:
A biopsy involves the removal of a small tissue sample from the kidney tumor to be examined under a microscope. This procedure helps confirm the presence of cancerous cells and determine the specific type and grade of kidney cancer.
Blood Tests:
Certain blood tests can be helpful in the diagnosis of kidney cancer. For instance:
Complete Blood Count (CBC):
A CBC can detect anemia or abnormalities in blood cell counts, which may indicate the presence of kidney cancer.
Renal Function Tests:
These tests assess the kidney’s ability to filter waste and may help identify kidney dysfunction related to cancer.
Intravenous Pyelogram (IVP):
An IVP is a contrast dye-based X-ray procedure used to visualize the urinary tract, including the kidneys and ureters. It can reveal any blockages or abnormalities caused by kidney tumors.
Molecular and Genetic Testing:
In some cases, molecular or genetic testing may be performed on the tumor tissue to identify specific genetic mutations or biomarkers that can guide treatment decisions, especially for targeted therapies or immunotherapies.

Treatment for kidney cancer:
The treatment of kidney cancer depends on various factors, including the stage of the cancer, the size and location of the tumor, the overall health of the patient, and the presence of any other medical conditions. Here are six common treatment approaches for kidney cancer:
Surgery:
Surgery is often the primary treatment for kidney cancer, especially if the tumor is localized and has not spread to other organs. There are different surgical options depending on the tumor size and location:
Radical Nephrectomy:
This involves the removal of the entire affected kidney, surrounding tissues, and nearby lymph nodes.
Partial Nephrectomy:
In cases where the tumor is small and confined to a specific part of the kidney, only the tumor and a small margin of healthy tissue are removed, preserving the rest of the kidney.
Targeted Therapy:
Targeted therapies are drugs that specifically target certain molecules or pathways involved in the growth and spread of cancer cells. They can help slow down or inhibit tumor growth and are often used for advanced or metastatic kidney cancer.
Immunotherapy:
Immunotherapy is a type of treatment that stimulates the body’s immune system to recognize and attack cancer cells. Immune checkpoint inhibitors are commonly used in advanced kidney cancer to enhance the immune response against the tumor.
Radiation Therapy:
Radiation therapy uses high-energy beams to target and destroy cancer cells. It may be used in combination with surgery or as palliative treatment to alleviate symptoms and pain in advanced cases of kidney cancer.
Ablation Therapy:
Ablation techniques, such as radiofrequency ablation (RFA) or cryoablation, use heat or cold to destroy small kidney tumors. This approach is suitable for patients who may not be eligible for surgery due to medical reasons.
Surveillance (Active Monitoring):
For small, slow-growing tumors or cases where surgery is not immediately necessary, doctors may choose to closely monitor the tumor’s progression through regular imaging tests. Treatment is deferred until there are signs of tumor growth or spread.
In many cases, a combination of treatments may be used to provide the best possible outcome for the patient. The choice of treatment is determined by the oncology team after careful consideration of the individual’s health status and the specific characteristics of the kidney cancer.
