Kidney Cancer

Kidney Cancer

Kidney cancer is a cancer that begins in the kidneys. It occurs when healthy cells in one or both kidneys proliferate uncontrollably and form a lump (known as a Tumor).

Signs and Symptoms

Most people have no signs or symptoms in the early stages. Kidney cancer is typically discovered by chance during an abdominal (belly) imaging test for another reason. As the tumors grows, you may experience:

  • Urine with blood
  • Backache in the lower back
  • A lump in the lower back or along the side of the waist
  • Weight loss that is not explained, night sweats, fever, or fatigue

Types of Kidney cancer

Renal cell carcinoma

Renal cell carcinoma (RCC) is the most common type of adult kidney cancer. RCC typically begins in the lining of tiny tubes in the kidney known as renal tubules. RCC typically remains in the kidney, but it can spread to other parts of the body, most commonly the bones, lungs, or brain.

Clear cell renal cell carcinoma

The most common type of kidney cancer is clear cell renal cell carcinoma, also known as ccRCC or conventional renal cell carcinoma. The tumors is called clear cell renal cell carcinoma because of how it appears under a microscope. The tumor cells appear clear, like bubbles.

In adults, ccRCC accounts for roughly 80% of all cases of renal cell carcinoma. Adults are more likely than children to develop ccRCC. Renal cell carcinoma accounts for 2% to 6% of all cases of kidney cancer in children and young adults."

Kidney cancers that are uncommon

  • Rare kidney cancers most commonly affect children, teenagers, and young adults
  • PRCC stands for papillary renal cell carcinoma.
  • 15% of all cases of renal cell carcinoma
  • A tumor (or tumors) in the kidney tubes
  • Type 1 PRCC is more common and grows at a slower rate.
  • Type 2 PRCC is more aggressive and grows faster.
  • TRCC (translocation renal cell carcinoma)
  • It is responsible for 1% to 5% of all renal cell carcinomas and 20% of childhood cancers.
  • Tumor(s) found in the kidney
  • TRCC usually grows slowly and without symptoms in children.
  • TRCC is aggressive and rapidly growing in adults.

Benign (non-cancerous) kidney tumors

Noncancerous kidney tumors grow in size but do not spread to other parts of the body and are usually not fatal. The most common treatment is surgical removal, and most tumors return.

A papillary renal adenoma is a type of renal adenoma.

The most prevalent benign kidney tumor

Tumors are small, slow-growing masses that frequently go undetected.

Typically, an incidental finding on an imaging test performed for another reason.


Tumors begin in the cells of the kidney collecting ducts and can grow in either kidney. Tumors can grow to be quite large around the These tumors can grow to be quite large, ranging from just over an inch (walnut) to 4 inches (grapefruit).


Overgrowth of blood vessel and smooth muscle tissue cells can also cause benign fatty tumors.

Tumors are not cancerous, but they can grow to be quite large and destroy nearby tissue.

Tumors larger than an inch and a half in diameter can cause internal bleeding.

Non-Surgical Treatment of Kidney Cancer Cyberknife S7 Robotic Radiotherapy System

The most common treatment for kidney cancer is surgery to remove all or part of the kidney. However, your treatment will be determined by the stage of your disease, your general health, your age, and other factors.
