Kidney cancerhappens when cells in one or both kidneys grow out of control. Cancer cells form tumors that make it difficult for normal cells to function.

According to the Centers for Disease Control and Prevention (CDC), kidney cancer is theeighth most common cancerin the United States. Every year, more than 65,000 people get kidney cancer, and about 14,000 die from the disease.

  • Urinalysis: Lab workers will check your urine to see if it contains blood or cancer cells.
  • Blood chemistry tests: These tests show how well the kidneys are working.
  • Complete blood count (CBC): People with kidney cancer often have low red blood cell counts.
  • Ultrasound:Uses sound waves to take pictures of your kidneys. Can also help guide a biopsy needle into a tumor.

Is Kidney Cancer Curable?

When it’s detected early, doctors have a very good chance of curing kidney cancer. Even advanced cases benefit from thekidney cancer treatmentsavailable from UPMC.

Here are the most common ways doctors treat kidney cancer:

  • Surgery: This is the most common way to treat kidney cancer. Doctors remove the tumor and sometimes part or all of the affected kidney. New laparoscopic techniques mean shorter hospital stays and faster recovery times.
  • Tumor ablation: This is an option for people who are too sick to have surgery. This method employs extreme heat or cold to destroy the cancer cells.
  • Radiation therapy: This is another option for people who can’t have surgery.
  • Immunotherapy: This treatment boosts your immune system to attack kidney cancer cells.
  • Targeted therapy: This treatment uses drugs that target cancer cells and are taken as a pill or given through a vein. Unlike chemotherapy, these drugs target cancer cells and don’t affect normal cells. They have different side effects than chemotherapy.
  • Chemotherapy: Cancer-fighting drugs are given through a vein or taken as pills. Chemotherapy usually doesn’t work well for kidney cancer, but doctors may try it if other treatments fail.

The treatment for kidney cancer — and its outcome — depends on many factors. They include your age, the stage of the disease, and how fast it’s spreading. Doctors sometimes use multiple treatments together to fight the disease.
