Kidney cancer occurs when abnormal cells in the kidney grow uncontrollably, forming a tumor. The most common type of kidney cancer is called renal cell carcinoma (RCC), which starts in the kidney's small filtering units, known as nephrons. Detecting kidney cancer early is crucial because it improves the chances of successful treatment. Signs of kidney cancer may include blood in the urine, lower back pain, weight loss, or a lump in the side or abdomen. However, many people may not notice symptoms in the early stages, which is why regular check-ups are important for early diagnosis. Treatment for kidney cancer usually involves surgery to remove the tumor or, in some cases, the entire kidney. Doctors may also use targeted therapies, radiation, or immunotherapy to prevent the cancer from spreading. Kidney cancer can spread to other parts of the body if not treated promptly, so seeking medical help at the first sign of symptoms is essential. Maintaining a healthy lifestyle, such as not smoking and eating a proper diet, can also help reduce the risk of developing kidney cancer.
Kidney cancer may not cause symptoms in the early stages, but as it progresses, symptoms can include:
Blood in the urine (may look pink, red, or brown)
Lower back pain (usually on one side, not due to injury)
A lump or mass in the lower back or side
Unexplained weight loss
Fever (that comes and goes)
Fatigue (feeling unusually tired or weak)
Loss of appetite
Other conditions can also cause these symptoms, so it's essential to consult a doctor.
The exact cause of kidney cancer is not known, but certain factors can increase your risk. Kidney cancer develops when genetic mutations occur in kidney cells, causing them to grow uncontrollably and form a tumor. Over time, these cancer cells can spread to other parts of the body (metastasis).
If you notice any of the following symptoms, it's essential to see a doctor:
Blood in your urine
Persistent lower back pain or a lump in the side
Unexplained weight loss, fever, or extreme fatigue
Even if the symptoms seem mild, getting checked is better, as early detection of kidney cancer can improve the chances of successful treatment.
To diagnose kidney cancer, your doctor may recommend the following tests:
Imaging tests:
Ultrasound: Helps visualize the kidney and detect tumors.
CT scan or MRI: Gives detailed images of the kidney and nearby organs.
X-rays: Used to check if cancer has spread to the lungs.
Urine tests: To check for blood in the urine or other abnormalities.
Blood tests: To assess kidney function and check for any abnormal substances in the blood.
Biopsy: A small sample of kidney tissue is taken and examined under a microscope to confirm cancer.
Do's:
Stay hydrated: Drink enough water to keep your kidneys healthy.
Follow your treatment plan: Attend all scheduled medical appointments and follow the instructions provided by your healthcare team.
Eat a balanced diet: A healthy diet supports overall well-being and helps maintain strength during treatment.
Exercise regularly: Engaging in light exercise can help keep you active and boost your energy levels.
Monitor your symptoms: Report any changes in symptoms to your doctor immediately.
Don'ts:
Avoid smoking: Smoking is a significant risk factor for kidney cancer. Quitting can lower your risk and help with recovery.
Limit alcohol consumption: Alcohol can strain your kidneys, so it's best to limit or avoid it.
Don't ignore symptoms: If you notice new or worsening symptoms, seek medical attention immediately.
Avoid processed and high-fat foods: These foods can increase cancer risk and negatively impact your recovery.
