Kidney cancer is a type of cancer that starts in the kidneys. The kidneys are two bean-shaped organs located in the abdomen, which removes extra water and waste from the blood, producing urine.

In this article, we’ll discuss the symptoms of kidney cancer and the diagnostic methods for detecting it.

Symptoms of Kidney Cancer

Most of the time, kidney cancer is asymptomatic in its early stages. However, as the tumor grows larger or metastasizes (spreads) to other parts of the body, it causes a variety of symptoms, including:.

1. Blood in the urine

Blood in urine or hematuria is the most common symptom of kidney cancer. It may look pink, red, or brown, and can be accompanied by blood clots. The presence of blood in the urine should not be ignored, even if it is painless.

2. Pain in the side or lower back

Pain in the side or lower back is another common symptom of kidney cancer. It usually starts as a dull ache or pain in the flank, which is felt just below the ribcage on the backside of the body. The pain may become severe as the tumor grows larger.

3. Unexplained weight loss

Weight loss is often a sign of advanced kidney cancer. It may happen even when the person is consuming enough food. Unexplained weight loss should prompt medical attention, especially when accompanied by other symptoms.

4. Fatigue

Fatigue is a feeling of tiredness, weakness, or lack of energy. A person with kidney cancer may experience fatigue due to the body’s increased demand for energy to fight the cancerous cells.

5. Fever

Fever is a common symptom of many types of cancer, including kidney cancer. It may be intermittent or continuous and may last for several days. The fever usually does not respond to antibiotics or other medications.

Diagnostic Methods for Kidney Cancer

If you are experiencing any of the above symptoms, it is important to see a doctor. The doctor may recommend the following tests to diagnose kidney cancer:.

1. Physical exam

In a physical exam, the doctor will examine the abdomen, back, and sides for any lumps or abnormalities. He may also ask about your medical history and any ongoing symptoms.

2. Blood and urine tests

Blood and urine tests help doctors determine how well your kidneys are functioning. They may also detect other abnormalities in the blood or urine that are associated with kidney cancer.

3. Imaging tests

Imaging tests are the most common methods to diagnose kidney cancer. Imaging tests include:.

a. Ultrasound

Ultrasound uses high-frequency sound waves to create images of the kidneys and other organs in the abdomen. It is painless, non-invasive, and does not expose the patient to radiation.

b. CT (Computed Tomography)

CT scan takes detailed images of the abdomen from different angles. It uses a combination of X-rays and computer technology to create images. CT scan is relatively quick and non-invasive but involves exposure to radiation.

c. MRI (Magnetic Resonance Imaging)

MRI uses a magnetic field and radio waves to create high-resolution images of the kidneys. It is safe and does not involve the use of radiation, but it requires the patient to lie still in a narrow tube for about 30-60 minutes.

4. Biopsy

A biopsy is a procedure in which the doctor removes a small piece of tissue from the kidney for analysis in a laboratory. Biopsy is usually done using a needle and is guided by ultrasound or CT scan.

Biopsy is the definitive method for diagnosing kidney cancer.

Conclusion

Kidney cancer is a serious condition but early detection and treatment can improve the prognosis. If you are experiencing any symptoms or have risk factors for kidney cancer, it is essential to see a doctor for evaluation.

Don’t ignore any symptoms, especially blood in the urine. They could be indicative of kidney cancer.
