Kidney cancer is among the top ten most common cancers in the world, affecting both men and women equally.

The kidneys are vital organs responsible for filtering your blood, and when cancer develops in them, it can spread quickly to other parts of the body. Although the symptoms of kidney cancer are often hard to detect at early stages, it’s essential to be aware of them to ensure early diagnosis and treatment. This article will discuss eight symptoms of kidney cancer that you must know.

1. Blood in urine

Blood in the urine, also known as hematuria, can indicate kidney cancer. It’s essential to note that not all cases of hematuria are due to cancer, but it’s better to have it checked by a healthcare professional.

Blood in the urine can occur in different amounts, ranging from microscopic amounts to visible blood clots.

2. Unexplained weight loss

If you are losing weight without any changes in your diet or exercise routine, it’s time to see your doctor. Unexplained weight loss can be a sign of kidney cancer or another underlying condition that needs treatment.

In some cases, cancer cells can disrupt the normal functioning of the body’s metabolism, leading to weight loss.

3. Constant fatigue

If you feel tired all the time, despite getting enough rest, it may be a sign of kidney cancer. Cancer cells can release substances that interfere with the body’s normal functioning, leading to fatigue.

Additionally, anemia, a condition often associated with cancer, can also lead to constant tiredness.

4. Swelling in the lower extremities

Kidney cancer can lead to swelling in the legs, ankles, or feet. This symptom occurs due to the accumulation of fluids in the body when the kidneys can’t flush them out.

Although swelling can be caused by other conditions, such as heart and liver disease, it’s essential to seek medical attention to determine the cause.

5. Back pain

Back pain is a common symptom of kidney cancer, particularly on the side where the tumor is located. The pain can be sharp or dull and can occur at any time, regardless of activity level.

If you have persistent back pain that doesn’t improve with rest or pain medication, it’s time to see your doctor.

6. Low-grade fever

A low-grade fever, usually below 100.4°F (38°C), can occur in some people with kidney cancer. Fever often signals an infection in the body, but in some cases, it can indicate cancer.

If you have a fever that lasts more than a day or two, see your healthcare professional for an evaluation.

7. Change in urinary patterns

Kidney cancer can lead to changes in urination patterns. You may experience frequent urination, painful urination, or urge incontinence, which is the sudden need to urinate.

These symptoms can also indicate other conditions, such as urinary tract infections or prostate problems. It’s important to see your doctor to determine the cause and receive proper treatment.

8. Loss of appetite

Loss of appetite can also indicate kidney cancer, but it’s a nonspecific symptom that can occur in many other conditions. Cancer cells can affect the body’s hormones and metabolism, leading to decreased appetite.

Additionally, some cancer treatments can cause nausea and vomiting, affecting your appetite.

Conclusion

Kidney cancer can be challenging to detect at early stages, making it essential to be aware of the symptoms that may indicate its presence. If you experience any of the above symptoms, seek medical attention to determine the underlying cause.

Early detection and treatment can improve your chances of a better outcome.
