Kidney and Bladder Cancer
Overview of Kidney and Bladder Cancer
Kidney and Bladder Cancer Meaning in Urdu
گردے اور مثانے کا کینسر دو اندرونی اعضا گردوں اور مثانے کو متاثر کرتا ہے۔ کینسر کی یہ قسم انتہائی خطرناک ہوتی ہے کیوں کہ گردے انسانی زندگی کی بقا میں اہم کردار ادا کرتے ہیں، جب کہ پیشاب کو خارج کرنے میں مثانے کا کردار نہایت اہم ہوتا ہے۔ تمباکو نوشی، موٹاپے، اور ہائی بلڈ پریشر جیسی بیماریوں کی وجہ سے گردے اور مثانے کے کینسر کے خطرات میں اضافہ ہو جاتا ہے۔ اس بیماری کی وجہ سے پیشاب میں خون، کمر درد، پیٹ کے ایک حصے میں گلٹی، تھکاوٹ، وزن میں کمی، بخار، اور بھوک کی کمی کا سامنا کرنا پڑ سکتا ہے۔
Definition
Kidney cancer, also known as renal cell carcinoma, is a type of cancer that develops in the cells of the kidneys. The kidneys are two bean-shaped organs located on either side of the spine, and they are responsible for filtering blood and removing waste products from the body.
Bladder cancer develops in the bladder, a hollow organ in the lower part of the abdomen that stores urine until it is out of the body. Most bladder cancers start in the inner lining of the bladder and can sometimes spread to other body parts.
Both kidney and bladder cancers are genitourinary cancers that impact the urinary and reproductive systems. Some common symptoms of these cancers may include blood in the urine, frequent urination, pain or discomfort during urination, and back pain.
Prevalence of Kidney and Bladder Cancer
Globally, bladder cancer is the 10th most common cancer, affecting every 6 out of 100,000 people. Men are three times more likely to develop bladder cancer compared to women. On the other hand, Kidney Cancer is the 14th most common cancer worldwide, affecting every 4 out of 100,000. Both kidney and bladder cancer are prevalent in the elderly.
Signs and Symptoms of Kidney and Bladder Cancer
Kidney and bladder cancer can have a variety of symptoms. Some of the common symptoms include:
Symptoms of Kidney Cancer
- Blood in the urine (haematuria)
- Pain in the side or back that doesn't go away
- A lump or mass in the side of the abdomen
- Fatigue
- Unexplained Weight loss
- Fever
- Loss of appetite
Symptoms of Bladder Cancer
- Blood in the urine (haematuria)
- Pain or burning during urination
- Frequent urination
- Feeling the need to urinate but being unable to do so
- Lower back pain or pain in the abdomen
- Fatigue
- Loss of appetite
- Unexplained weight loss
These symptoms can occur due to other conditions as well, so it's important to see a doctor for an accurate diagnosis.
Types of Kidney and Bladder Cancer
There are several types of kidney cancer and bladder cancer, which are listed below:
Types of Kidney Cancer
- Renal Cell Carcinoma: This is the most common type of kidney cancer, accounting for about 85% of all cases. It starts in the lining of small tubes in the kidney and can spread to other parts of the body.
- Transitional Cell (Urothelial) Carcinoma: This type of kidney cancer accounts for 5-10% of cases and starts in the lining of the renal pelvis, the area of the kidney where urine collects before it passes to the bladder. This type of cancer can also affect the ureter, a tube that connects the kidney to the bladder.
- Wilms Tumor: A rare type of kidney cancer, typically affecting children under the age of 5. Wilms tumors make up about 1% of kidney cancers.
- Sarcoma: Sarcoma is a rare condition. This particular malignancy forms in the soft tissue of the kidney, the kidney's thin capsule-like layer of connective tissue, or the surrounding fat. Surgery can treat renal sarcoma. Sarcoma, however, frequently returns to the kidney region or spreads to other parts of the body.
Types of Bladder Cancer
- Transitional Cell (Urothelial) Carcinoma: This is the most common type of bladder cancer, accounting for about 90% of all cases. It starts in the lining of the bladder and can spread to other parts of the body.
- Squamous Cell Carcinoma: This type of bladder cancer starts in the thin, flat cells that line the bladder. It is more common in certain parts of the world where bladder infections are common.
- Adenocarcinoma: This type of bladder cancer starts in the cells that produce mucus in the bladder lining. It is rare and accounts for only about 1% of all bladder cancers.
Causes of Kidney and Bladder Cancer
Kidney and bladder cancer have almost similar causes, including:
Causes of Kidney Cancer
- Smoking: Smoking increases the risk of kidney cancer by damaging the DNA in cells and causing mutations that can lead to cancer.
- Obesity: People who are overweight or obese have a higher risk of kidney cancer, likely due to hormonal changes and other factors related to obesity.
- High blood pressure: Chronic high blood pressure may damage the kidneys and increase the risk of kidney cancer.
- Family history: A family history of kidney cancer increases the risk of developing the disease.
- Workplace exposure: Exposure to chemicals such as cadmium, asbestos, benzene, and organic solvents can increase the risk of kidney cancer.
Causes of Bladder Cancer
- Smoking: Smoking is the most significant risk factor for bladder cancer, as it exposes the bladder to harmful chemicals in cigarette smoke.
- Exposure to certain chemicals: Exposure to certain chemicals such as those used in the manufacturing of rubber, textiles, and paint products, as well as in hairdressing and dry cleaning, can increase the risk of bladder cancer.
- Chronic bladder inflammation: Chronic inflammation of the bladder due to recurrent urinary tract infections, bladder stones, or other conditions can increase the risk of bladder cancer.
- Family history: A family history of bladder cancer increases the risk of developing the disease.
Risk Factors of Kidney and Bladder Cancer
There are several risk factors associated with kidney and bladder cancer. Some of the common risk factors for kidney cancer are:
- Smoking: Smoking is one of the most significant risk factors for kidney cancer. It increases the risk by two to three times.

- High Blood Pressure: Chronic high blood pressure is a risk factor for kidney cancer.
- Family history: If you have a family history of kidney cancer, you may be at a higher risk of developing it.
- Age: The risk of kidney cancer increases with age. Most cases are diagnosed in people over the age of 50.
- Gender: Men are more likely to develop kidney cancer than women.
The common risk factors for bladder cancer are:
- Smoking: Smoking is the most significant risk factor for bladder cancer. It increases the risk by four times.
- Exposure to Chemicals: People who are exposed to certain chemicals, such as those used in dyeing, printing, and rubber manufacturing, may be at a higher risk of developing bladder cancer.
- Chronic Bladder Infections: Chronic bladder infections or irritation may increase the risk of bladder cancer.
- Age: The risk of bladder cancer increases with age. Most cases are diagnosed in people over the age of 55.
- Gender: Men are three times more likely to develop bladder cancer than women.
- Race: White people are more likely to develop bladder cancer than other races
Complications of Kidney and Bladder Cancer
Complications can vary depending on the stage of cancer and the individual's overall health. Some possible complications include:
Complications of Kidney Cancer
- Spread of cancer to other parts of the body, such as the lungs, liver, or bones
- Blockage of the ureter, which can lead to kidney damage and potentially life-threatening complications like kidney failure
- High blood pressure
- Paraneoplastic syndromes are a group of rare disorders that can develop in people with cancer due to the immune system's response to cancer cells
Complications of Bladder Cancer
- Recurrence of cancer after treatment
- Spread of cancer to nearby organs and tissues, such as the prostate or uterus
- Blockage of the urethra, which can cause difficulty urinating
- Urinary incontinence or leakage
- Urinary tract infections
- Anemia due to blood loss in urine
People with kidney or bladder cancer need regular medical care and follow-up to manage and monitor potential complications.

Prevention
While there is no guaranteed way to prevent kidney or bladder cancer, there are some steps you can take to reduce your risk of developing these types of cancer. These steps include:
- Quit smoking or never start: Smoking is a significant risk factor for kidney and bladder cancer. If you smoke, quitting can reduce your risk.
- Stay hydrated: Drinking plenty of fluids can help prevent bladder cancer by diluting any potentially harmful substances in your urine.
- Maintain a healthy weight: Obesity increases the risk of kidney and bladder cancer, so maintaining a healthy weight through a balanced diet and regular exercise can help reduce your risk.
- Practice safe Intercourse: Certain sexually transmitted infections like HPV have been linked to bladder cancer, so using protection during sexual activity can reduce your risk.
- Protect yourself from harmful chemicals: Exposure to certain chemicals like arsenic and benzene can increase the risk of kidney and bladder cancer.
- Avoid exposure to harmful chemicals whenever possible, and wear protective gear if you work in an industry that involves exposure to potentially harmful chemicals.
- Get regular medical check-ups: Regular medical check-ups can help detect any signs of kidney or bladder cancer early when treatment is most effective.
It's important to remember that while these steps can help reduce your risk of kidney and bladder cancer, there are no guarantees, and some people may still develop cancer even if they take these precautions. Regular medical check-ups and screenings are still essential to catch potential cancer early.
Diagnosis
Cancer diagnosis usually involves a combination of medical history, physical examination, imaging tests, and laboratory tests. Here are some of the methods used to diagnose kidney and bladder cancer:
- Medical history and physical examination: The doctor will ask about your symptoms and medical history and perform a physical exam to check for any lumps or swelling.
- Urine tests: Urine tests can detect the presence of blood or abnormal cells, which can be signs of kidney or bladder cancer.
- Imaging tests: Imaging tests such as CT scans, MRIs, and ultrasounds can provide detailed pictures of the kidneys and bladder, allowing doctors to identify any abnormalities.
- Biopsy: A biopsy involves taking a small tissue sample from the kidney or bladder and examining it under a microscope to look for cancer cells.
- Cystoscopy: Cystoscopy involves inserting a thin, flexible tube with a camera into the bladder to examine it for any abnormalities.
If cancer is detected, further tests such as bone scans or chest X-rays may determine if cancer has spread to other body parts. It's important to talk to a Urologist and Oncologist if you experience any symptoms of kidney or bladder cancer, such as blood in your urine, pain in your back or side, or frequent urination.
Treatment of Kidney and Bladder Cancer | When to Consult a Doctor
The treatment for kidney and bladder cancer depends on the cancer stage, location, and the patient’s general health. Here are some treatment options for kidney and bladder cancer:
- Surgery: Surgery is often the first line of treatment for kidney and bladder cancer. In kidney cancer, the entire kidney or just the tumor may be removed. In bladder cancer, surgery may involve removing a portion of the bladder or the entire bladder.
- Radiation therapy: Radiation therapy uses high-energy radiation to kill cancer cells. It may be used alone or in combination with surgery or chemotherapy.
- Chemotherapy: Chemotherapy uses drugs to kill cancer cells. It may be given orally or intravenously and used alone or in combination with surgery or radiation therapy.
- Immunotherapy: Immunotherapy uses drugs that help the body's immune system to recognize and attack cancer cells.
- Targeted therapy: Targeted therapy uses drugs targeting the cancer cells' unique features, such as specific proteins.
It is essential to consult with a medical professional team consisting of Urologists and Oncologists to determine the best course of treatment for each case.
