Kidney cancer, also known as renal cancer, is a type of cancer that originates in the kidneys. It occurs when the cells in the kidney grow uncontrollably, forming a mass or a tumor.

Kidney cancer is among the 10 most common cancers in both men and women, with the highest incidence in people aged 55 to 75. It is important to know the symptoms of kidney cancer and be prepared, as early detection can significantly improve treatment outcomes.

Types of Kidney Cancer

There are several types of kidney cancer. The most common type is renal cell carcinoma (RCC), which accounts for approximately 90% of kidney cancer cases. RCC develops in the small tubes within the kidney, called renal tubules.

Other rare types of kidney cancer include transitional cell carcinoma, Wilms tumor (a childhood kidney cancer), and renal sarcoma.

Common Symptoms of Kidney Cancer

Early-stage kidney cancer often does not cause any noticeable symptoms. However, as the tumor grows larger or spreads to other parts of the body, symptoms may start to appear.

It is important to be aware of these symptoms, as they may indicate the presence of kidney cancer:.

1. Blood in the Urine

Hematuria, or blood in the urine, is one of the most common symptoms of kidney cancer. It may cause the urine to appear pink, red, or brown. Sometimes, blood in the urine is not visible to the naked eye and can only be detected through a urine test.

If you notice blood in your urine, it is essential to consult a healthcare professional for further evaluation.

2. Lower Back Pain

Kidney cancer can cause persistent lower back pain. The pain may be dull or sharp and can affect one side of the back or both.

It is important to note that lower back pain can be attributed to various other conditions, so it is necessary to consult a healthcare professional for an accurate diagnosis.

3. Unexplained Weight Loss

Sudden and unexplained weight loss can be a symptom of kidney cancer. The weight loss may be significant and occur even without changes in diet or physical activity.

If you experience unexplained weight loss, it is important to consult a healthcare professional to determine the underlying cause.

4. Fatigue and Weakness

Chronic fatigue and weakness are common symptoms of kidney cancer. The cancer cells consume a significant amount of energy, leading to fatigue and a general feeling of weakness.

If you feel abnormally tired and weak without any apparent reason, it is advisable to seek medical attention.

5. Loss of Appetite

Kidney cancer can cause a loss of appetite, leading to unintentional weight loss. The tumor may disrupt the normal functioning of the kidney, affecting the body’s metabolism and appetite.

If you experience a loss of appetite accompanied by other symptoms, it is important to consult a healthcare professional.

6. Swelling in the Legs and Ankles

If kidney cancer spreads to the lymph nodes or other organs, it may cause fluid retention, leading to swelling in the legs and ankles. This swelling, known as edema, occurs due to impaired kidney function.

If you notice persistent or worsening swelling in your legs and ankles, it is essential to seek medical evaluation.

7. Persistent Fever

A persistent fever can sometimes indicate the presence of kidney cancer. The fever may occur sporadically or last for an extended period.

If you have an unexplained fever that does not resolve, it is important to consult a healthcare professional for a proper diagnosis.

8. Anemia

Some individuals with kidney cancer may develop anemia, a condition characterized by a low red blood cell count. Anemia can cause symptoms such as fatigue, weakness, and shortness of breath.

If you experience these symptoms along with other signs of kidney cancer, it is crucial to seek medical attention.

9. High Blood Pressure

Kidney cancer can occasionally lead to high blood pressure. The tumor can affect the kidney’s regulation of blood pressure, resulting in hypertension.

If you have uncontrolled high blood pressure alongside other kidney cancer symptoms, it is advisable to consult a healthcare professional for evaluation.

10. Persistent Cough

In rare cases, kidney cancer can metastasize to the lungs, leading to a persistent cough. If you have a cough that does not go away or worsens over time, it is important to have it assessed by a healthcare professional.

Conclusion

Being aware of the symptoms of kidney cancer is crucial for early detection and improved treatment outcomes. If you experience any of the mentioned symptoms, it is advisable to consult a healthcare professional for further evaluation.

Remember, early detection and timely intervention play a significant role in the successful management of kidney cancer.
