Kidney Cancer – Signs, Stages, and Management Options

According to the American Cancer Society, kidney cancer is a rare but severe disease that people have a 2 percent chance of developing. And the risk is more prevalent in those who follow an unhealthy lifestyle, have bad food habits, or are exposed to asbestos and benzene chemicals. Nonetheless, the disease is easier to treat if diagnosed before stage 4. The survival chance increases if one recognizes its early signs and receives proper medical treatment.
Early warning signs of kidney cancer
The tumor results from an abnormal mutation in a single cell that begins to multiply and develop exponentially over time. Early signs of kidney cancer are often unrecognizable. Kidney cancer can be fully curable if the disease is diagnosed early on. But since the organ is deep into one’s body, the symptoms don’t usually show until the tumor has grown or spread already. Here are some prevalent early signs that could indicate a kidney tumor. If one experiences these signs, it’s advisable to seek medical help immediately.
Blood in urine
Finding blood in one’s urine doesn’t immediately mean one has kidney cancer. Urinary tract infection (UTI), bladder or kidney stones may also cause bloody urine, also known as hematuria. But this is also the main sign of cancer developing in one’s kidney, so it’s best to get a CT scan, ultrasound, or biopsy done to find the origin of the symptom.
Back pain and lumps
Feeling pain in the side or lower back or feeling an abnormal mass on one’s abdomen, lower back, or side or ankle swelling can be a kidney cancer sign. A lump anywhere on one’s body must be medically examined immediately.
Fever and night sweats
Night sweats or a sudden fever with no particular cause that doesn’t go away easily can be an alarming sign of worry.
Loss of appetite
Another common sign of kidney cancer is if one suddenly loses appetite or doesn’t feel as hungry as before.
Weight loss
One may also lose muscle and body mass, have a compromised immune system, and feel weak.
Fatigue
Cancerous cells consume the most energy, leading one to experience chronic fatigue or tiredness. While usual tiredness arising from lack of sleep or working overtime is common, sudden unexplained tiredness without any lifestyle changes can cause concern. This tiredness also doesn’t go away even after extended resting periods. Combined with any other symptoms, experiencing fatigue should ideally prompt one to consult a doctor for any underlying health issue, including kidney cancer.
How is kidney cancer detected?
Detection of kidney cancer is of utmost importance before it progresses to advanced stages. For example, a physician may recommend a kidney specialist who will run a test to detect the tumor. The tests may include one or more of the following:
CT scan or MRI
CT scan is an X-ray scan that allows a doctor to locate tumors, stones, and other issues in one’s bladder, kidneys, and ureters.
Renal ultrasound
This machine helps the doctor to create and record images of one’s kidney onto a computer using sound waves.
Biopsy
A biopsy procedure studies a small portion of kidney tissue under a microscope for any indication of abnormal cell development.
Learning about the tumor’s location, family history, lifestyle, and habits enables one’s doctor to formulate the best possible treatment plan. Since cancer screenings are not available to those who aren’t at risk, it’s advisable to run routine scans and take urine tests at regular intervals. This will help in detecting and preventing cancer at an early stage.
Four stages of kidney cancer
Kidney cancer is classified into four stages. Stage 1 kidney cancer is easily curable amongst all since the tumor size is tiny. A partial nephrectomy is a joint surgery that effectively removes the tumor at this stage. Stage 2 tumors usually grow more significant than seven centimeters in diameter and mostly require the surgeon to remove the kidney infected with the tumor. Since humans have two kidneys, a patient can live relatively well with one kidney without any severe health complications.
Stage 3 tumor spreads outside one’s kidney to the adjacent adrenal glands or other organs. According to sources, the 5-year survival rate for stage 3 kidney cancer patients is as low as 53 percent after diagnosis. Here, radical nephrectomy removes both the kidney and the nearby adrenal gland.
According to the American Cancer Society, the 5-year survival rate for stage 4 kidney cancer drops to eight percent. Here, the tumor is wholly metastasized, and treatments like chemotherapy or surgery are not usually effective. In addition, doctors may recommend palliative care for patients at this stage.
Treatment options
Doctors recommend treatments for patients depending on their age, cancer stage, and overall health condition to support recovery. A medical expert may opt for watchful waiting for an aged patient with a tumor size of fewer than 1.5 inches. The waiting entails regular check-ups and imaging tests to keep an eye on the growth of the tumor. Once it grows larger than 1.5 inches, a doctor may quickly perform surgery. The surgery involves cutting off the tumor as much as possible without losing the kidney. Also, surgeries can be of different kinds. Some of them are:
Partial nephrectomy
This removes the tumor from one’s kidney. The tumor can be as big as 2.75 inches and is commonly used during early-stage kidney cancer. This surgery is usually ineffective if cancer spreads to nearby body parts.
Radical nephrectomy
This removes the affected kidney, and some surrounding tissue, adrenal gland, and lymph nodes are affected. If both kidneys are removed, one may need a dialysis machine to clean one’s blood.
Other options
Some non-surgical treatments include targeted therapy, an immunotherapy that uses one’s immune system to fight cancer, radiation therapy that uses energy beams to kill cancerous cells, and clinical trials. Based on one’s condition, a medical professional may recommend one or a combination of therapies to fight kidney cancer.
