Kidney Cancer
Kidney cancer occurs when the cells in the kidney begin to grow abnormally and uncontrollably. It can affect people of all ages, but is more common in people over the age of 40. The exact causes of kidney cancer are unknown, but risk factors include smoking, obesity, high blood pressure, and a family history of the disease. Symptoms may include blood in urine, pain in the side or lower back, weight loss, and fever. Treatment options include surgery, radiation therapy, and chemotherapy. Early detection is key, and regular check-ups are recommended, especially for those with risk factors. Patients with kidney cancer have a higher chance of survival if it is caught early and treated promptly.
Symptoms of Kidney Cancer
What are the common causes of kidney cancer?
Kidney cancer is caused by mutations or changes in the genetic makeup of the cells in the kidneys. Some common risk factors that increase the likelihood of developing kidney cancer include smoking, being obese, having high blood pressure, family history of the disease, and certain genetic conditions such as von Hippel-Lindau disease.

Can obesity increase the risk of kidney cancer?
Blood in urine, also known as hematuria, can be a symptom of kidney cancer, but it is not always present. In fact, only about a third of people with kidney cancer have blood in their urine. Other symptoms of kidney cancer include pain or discomfort in the side or back, a lump or mass in the lower back, fatigue, weight loss, and fever.

What are the early warning signs of kidney cancer?
Yes, obesity is a risk factor for kidney cancer. Studies have shown that people who are obese are at greater risk for developing kidney cancer than those who are a healthy weight. This may be because obesity can cause hormonal changes and inflammation in the body that can contribute to the development of cancer.
Diagnosis of Kidney Cancer
What imaging techniques are commonly used to diagnose kidney cancer?
Imaging techniques that are commonly used to diagnose kidney cancer include computed tomography (CT) scan, magnetic resonance imaging (MRI), ultrasound, and positron emission tomography (PET) scan. A CT scan is typically the first imaging test done for kidney cancer as it provides detailed images of the kidneys and surrounding organs. MRI is also useful in determining the size and location of a kidney tumor, especially for patients whose kidneys cannot tolerate radiation exposure. Ultrasound is often used to evaluate the size and location of tumors and any spread of cancer to nearby organs. PET scan is used to determine the extent of cancer in the body and to evaluate the effectiveness of treatment.
What blood tests are performed to detect kidney cancer?
Blood tests that are performed to detect kidney cancer include complete blood count (CBC), liver function tests, and renal function tests. CBC measures the number of red and white blood cells and platelets in the blood. Liver function tests evaluate the function of the liver and renal function tests measure the kidney`s ability to filter waste products from the blood. Elevated levels of certain substances such as lactate dehydrogenase (LDH) and alkaline phosphatase may indicate the presence of kidney cancer.
How is a biopsy used in the diagnosis of kidney cancer?
A biopsy is used in the diagnosis of kidney cancer by taking a small tissue sample from the tumor and examining it under a microscope to determine if cancer cells are present. A biopsy is usually done when imaging tests cannot confirm the presence of cancer or provide enough information for proper diagnosis. Biopsy can be done as a needle biopsy, laparoscopic biopsy, or open biopsy, depending on the size and location of the tumor.
Can kidney cancer be detected through urine tests?
Urine tests are not commonly used to detect kidney cancer but can be used to rule out other conditions that may cause similar symptoms. Urine tests may show blood in the urine or proteinuria, which can be an early sign of kidney disease or another medical condition. In some cases, a urinalysis may be used to monitor kidney function and detect any abnormalities.
What physical exams are conducted to identify symptoms of kidney cancer?
Physical exams that are conducted to identify symptoms of kidney cancer include abdominal examination to feel for lumps or tumors, blood pressure measurement to rule out high blood pressure caused by kidney disease, and neurological examination to detect any signs of nerve damage. A physical exam may also include a review of medical history, risk factors, and any symptoms the patient may be experiencing. Imaging tests and other diagnostic procedures may be ordered based on the results of the physical exam. Source: Mayo Clinic.
Treatments of Kidney Cancer
What are the standard surgical treatments for kidney cancer?
Standard surgical treatments for kidney cancer include partial or radical nephrectomy, which involves removing a part or the entire kidney respectively. Cryotherapy, radiofrequency ablation, and arterial embolization are other minimally invasive procedures that can be used for small tumors.
How effective are radiation and chemotherapy in treating advanced kidney cancer?
Radiation therapy and chemotherapy are not typically effective in treating advanced kidney cancer. Chemotherapy has shown limited benefit, and radiation therapy is primarily used to relieve symptoms such as pain or to treat metastatic lesions in the bone or brain. Immunotherapy and targeted therapy are typically used instead for advanced kidney cancer.
Can targeted therapy be used as a single treatment for advanced kidney cancer?
No, targeted therapy is typically used in combination with other treatments such as immunotherapy or surgery for the treatment of advanced kidney cancer. Targeted therapy involves drugs that specifically target cancer cells, such as tyrosine kinase inhibitors and mTOR inhibitors.
What are the side effects of immunotherapy for kidney cancer?
Immunotherapy for kidney cancer can cause side effects such as fatigue, rash, diarrhea, nausea, and loss of appetite. Less common but more serious side effects can include severe or life-threatening reactions affecting the lungs, kidneys, or other organs. It is important to discuss the risks and benefits of immunotherapy with a healthcare provider before starting treatment.
How important is regular follow-up care after kidney cancer treatment?
Regular follow-up care after kidney cancer treatment is essential for monitoring the cancer’s progression and detecting any recurrences early. Follow-up care can involve physical exams, blood tests, imaging studies, and other diagnostic tests. The frequency and type of follow-up care will vary depending on the stage of the cancer, the treatments used, and other factors. It is important to discuss a follow-up care plan with a healthcare provider.
Prognosis of Kidney Cancer
What is the expected survival rate for a person with advanced kidney cancer?
The expected survival rate for a person with advanced kidney cancer varies depending on many factors such as the stage of the cancer, the type of treatment received, and the overall health of the patient. According to the American Cancer Society, the five-year survival rate for stage IV kidney cancer is about 12 percent, meaning that 12 percent of people with stage IV kidney cancer survive for at least five years after their diagnosis.
Does the prognosis for kidney cancer worsen with age?
Age can be a significant factor in the prognosis for kidney cancer. According to a study published in the Journal of Urology, older age is associated with worse survival outcomes among patients with kidney cancer. However, the study also noted that the impact of age on survival may be influenced by other factors such as the stage of the cancer and the type of treatment received.
How does the stage of kidney cancer impact the prognosis?
The stage of kidney cancer can have a significant impact on the prognosis. Generally, the earlier the stage of the cancer, the better the prognosis. According to the National Cancer Institute, the 5-year survival rate for people with stage I kidney cancer is around 81 percent, while the 5-year survival rate for people with stage IV kidney cancer is only about 12 percent.
Can early detection improve the prognosis for kidney cancer?
Early detection of kidney cancer can improve the prognosis. According to the National Cancer Institute, the 5-year survival rate for people with kidney cancer that is diagnosed at an early stage is much higher than for those diagnosed at a later stage. This is because early-stage kidney cancer is more likely to be treatable and curable.
What are the most significant factors affecting kidney cancer prognosis?
The most significant factors affecting kidney cancer prognosis include the stage of the cancer, the type of treatment received, the overall health of the patient, and the presence of any other medical conditions. Other factors that can impact the prognosis include the size and location of the tumor, the grade of the cancer (how abnormal the cells look under a microscope), and whether the cancer has spread to other parts of the body. It is essential to discuss your specific prognosis with your doctor, as each case is unique and can be impacted by different factors.
Prevention of Kidney Cancer
What are the most effective ways to prevent the development of kidney cancer?
Prevention of kidney cancer involves avoiding certain risk factors such as smoking, obesity, high blood pressure, and occupational exposure to chemicals or toxins. According to the American Cancer Society, the most effective way to prevent kidney cancer is to quit smoking, maintain a healthy weight, and control blood pressure. Additionally, screening for certain genetic conditions that increase the risk of kidney cancer can also help prevent the disease.
