Abnormal growth of cells in one or both kidneys can cause kidney cancer. The kidneys are vital organs responsible for filtering waste products out of your blood such as urine, secreting hormones for regulating blood pressure, and keeping bones healthy. Getting treated for cancer at the earliest can improve the patient’s survivability and preserve renal function.
Causes
The cause of developing kidney cancer remains elusive, but risk factors are smoking, occupational exposure to carcinogens, obesity, family history, obesity, high blood pressure, having advanced kidney disease, and male gender.
Treatment
The main treatment options for kidney cancer are Surgery, Chemotherapy, and Radiotherapy. Some patients are also treated with Immunotherapy, Targeted Therapy, and Radiofrequency Ablation based on the requirement.

Kidney cancer occurs when cells in the kidney grow out of control. Treatment includes surgery, chemotherapy, and radiation therapy
Renal cell carcinoma is the most common type accounting for most cases of kidney cancer. It most often grows as a single tumour in a kidney but can grow as multiple tumours in one or both kidneys at the same time.
The subtypes of renal cell carcinoma include:
Clear cell renal cell carcinoma is the most common type.
Non-clear cell renal cell carcinoma includes papillary renal cell carcinoma and chromophobe renal cell carcinoma.
Other rare types include collecting duct carcinoma, renal medullary carcinoma, mucinous tubular and spindle cell carcinoma, and neuroblastoma-associated renal cell carcinoma.
Unclassified renal cell carcinoma: Histologically atypical types of cancer cells are categorised as unclassified types.
Other types of kidney cancer include:
Transitional cell carcinoma: Cancer begins in the lining of the renal pelvis.
Wilms tumour: This is a common type of kidney cancer in children.
Renal sarcomas: This is a rare form of kidney cancer beginning in the blood vessels or connective tissue of the kidney.
The symptoms of kidney cancer include:
Blood in urine
Persistent fever
Loss of appetite
Lower back pain
Pain on one side
Swelling or a lump can be felt near the kidney area or abdomen during clinical evaluation
Unexplained tiredness
Unexplained weight loss
Doctors will take the detailed medical history of the patient and perform a physical exam. If they suspect kidney cancer, the doctors will advise the following tests:
Urinalysis: Laboratory tests are performed to check for blood and cancer cells
Complete blood count: Patients with kidney cancer often present low red blood cell count
Ultrasound: The imaging study helps guide the biopsy needle into the tumour
Biopsy: A sample of kidney tissue is taken to confirm the cancer diagnosis
Chest X-ray: To check if the cancer has spread to the lungs
CT and MRI scans: To determine the extent of cancer spread
Treatment depends on the patient’s condition and the extent of cancer progression. However, most patients with kidney cancer are treated with Surgery, as living a normal life is possible with a single kidney. During the surgical procedure, the doctor may opt to remove the entire or partial kidney. Other treatment options include Radiation Therapy, Chemotherapy, Targeted Therapy, and Radiofrequency Ablation.
Doctors recommend surgical removal of the affected areas of the kidneys as the first line of treatment. The common procedures performed depending on the extent of kidney damage are:
Partial Nephrectomy: The procedure involves removing a part of the affected kidney while leaving behind healthy tissues.
Radical Nephrectomy: The whole kidney and the surrounding fatty tissue, the adrenal gland, and nearby lymph nodes affected by the tumours are removed.
Keyhole or Laparoscopic Procedure: Partial or complete removal of the affected kidney is possible with laparoscopic procedures. The surgery is preferred for patients in whom open surgery is not recommended, such as patients with high blood pressure.
Cryotherapy: The cancer cells are destroyed by subjecting them to extreme cold.
Radiation Ablation: The procedure uses heat from high-energy radio waves to destroy tumour.
Cancer originating in the upper urinary tract is referred to as transitional cell carcinoma. It is also referred to as urothelial carcinoma. The treatment for this type of cancer is similar to that of bladder cancer.
Wilms tumour is the most common kidney cancer in children. The tumour is successfully treated with a combination of Surgery, Chemotherapy, and Radiation Therapy compared to other kidney cancers.
The most common places where kidney cancer spreads are the lungs, lymph nodes, and bone.
Kidney cancer is not exclusively genetic, but a family history of renal cancer can certainly increase your risk.
Kidney cancer spreads quickly even during its early stages. The speed of cancer cell spread also depends on the age, health, and genetic history of the patient.
Recent advancements in technology have facilitated the diagnosis of cancer cases early when they are curable. When treated at early stages, kidney cancer patients have improved survivability. At advanced stages, kidney cancer is harder to treat.
