Understanding Kidney Cancer: Causes, Symptoms
What Is Kidney Cancer?
Understanding Kidney Cancer: Causes, Symptoms Kidney cancer is when cells in the kidneys grow too much and form tumors. The kidneys filter waste from the blood and make urine. When cells change and grow too fast, they can turn into cancer.
Definition and Overview
What is kidney cancer is about. It starts in the small tubes of the kidneys that filter blood. Kidney cancer has different types, with Renal Cell Carcinoma (RCC) being the most common. Acibadem Healthcare Group says catching kidney cancer early is key to stopping it from spreading.

ACIBADEM Health Point: The Future of Healthcare
We believe that everyone deserves access to quality healthcare, which is why we have established multiple branches in strategic locations. Whether you're in need of routine check-ups, specialized treatments, or emergency care, ACIBADEM Health Point is here for you.How Kidney Cancer Develops
Healthy kidney cells turn into cancer through a complex process. Genetic changes, often from smoking or being overweight, start it. These changes make cells divide too fast, forming a tumor. Acibadem Healthcare Group says knowing about what is kidney cancer means understanding that some tumors are harmless, but others are cancerous and dangerous.
Types of Kidney Cancer
It’s important to know about the different kinds of kidney cancer. There are three main types: renal cell carcinoma, urothelial carcinoma, and some rare ones. Each type has its own features and challenges.
Renal Cell Carcinoma
Renal cell carcinoma is the most common kidney cancer, making up about 85% of cases. It starts in the tiny filtering units of the kidneys called nephrons. It comes in types like clear cell, papillary, and chromophobe. Finding it early is key because it can spread to other parts of the body quickly.

Urothelial carcinoma, also called transitional cell carcinoma, affects the lining of the renal pelvis and ureter. It’s linked more to bladder cancer than to other kidney cancers. Spotting this type is important because the treatment is different. Smoking and being around certain toxins can increase the risk.
Rare Types of Kidney Cancer
Some kidney cancers are rare, like Wilms’ tumor in kids and renal sarcoma in the kidney’s tissues. Collecting duct carcinoma is another rare type that’s often more severe. Knowing about these rare cancers helps doctors make better treatment plans for patients.
Common Symptoms of Kidney Cancer
Knowing the signs of kidney cancer early can help a lot. The symptoms change from early to late stages. It’s key to know these to catch it early and get help fast.
Early Symptoms
Kidney cancer in its early stages might not show signs. But, some early signs can appear:
- Blood in the urine: Seeing blood in your pee is a key sign.
- Lower back pain: Pain on one side, below the ribs, is a warning.
- Unexplained weight loss: Losing weight for no reason could mean something’s wrong.
- Fatigue: Feeling always tired and weak is also a sign.
Advanced Symptoms
When kidney cancer gets worse, symptoms get more serious. Look out for these signs:
- Swelling of ankles or legs: Swelling can happen if your kidneys aren’t working right.
- Dramatic weight loss: Losing a lot of weight without a reason is a bad sign.
- Fever: A high fever that keeps coming back may mean kidney cancer has spread.
- Muscle wasting: Losing muscle and getting weaker is a big sign.
- Bone pain: If cancer spreads, you might feel pain in your bones or get fractures.
| Symptom | Early Stage | Advanced Stage |
|---|---|---|
| Blood in urine | Often present | More severe and frequent |
| Lower back pain | Persistent | Significant and widespread |
| Weight loss | Unexplained | Dramatic weight loss |
| Fatigue | Feeling of tiredness | Extreme fatigue |
| Swelling | Rarely present | Common, especially in legs |
| Fever | Occasional | Persistent or recurrent |
| Muscle wasting | Not typical | Common in advanced stages |
| Bone pain | Rarely present | Occurs if cancer has spread to bones |
Causes of Kidney Cancer
Kidney cancer has many causes. It comes from both genes and lifestyle choices. Knowing what causes it helps us find it early and prevent it.
Genetic Factors
Genes play a big part in getting kidney cancer. Some people have genes that make them more likely to get it. For example, certain diseases like von Hippel-Lindau disease and hereditary papillary renal cell carcinoma are linked to these genes.
These genes can make people more likely to get kidney cancer.
Lifestyle Influences
Lifestyle also affects kidney cancer risk. Smoking, eating too much fat, and being around toxins like pesticides can increase risk. But, staying active and keeping a healthy weight can lower these risks.
Studies show that these lifestyle choices are linked to getting kidney cancer. This shows how important it is to live healthily to prevent it.
Risk Factors for Kidney Cancer
Kidney cancer can be caused by many things. Knowing these risks helps us lower our chances of getting sick. We’ll talk about big risks like smoking, being overweight, and high blood pressure.
Smoking and Tobacco Use
Smoking and using tobacco are big risks for kidney cancer. People who smoke are more likely to get kidney cancer than those who don’t. The bad stuff in tobacco can change kidney cells and increase cancer risk.
Obesity and Diet
Being overweight and eating poorly are also risks. Being too heavy can change hormones in the body, raising cancer risk. Eating too much fat and processed foods makes it worse. Eating right and staying active can help prevent this.
High Blood Pressure
High blood pressure is another risk for kidney cancer. It can hurt the kidneys over time, making cancer more likely. Taking care of your blood pressure with medicine, changing your life, and checking it often is a good idea.
| Risk Factor | Impact on Kidney Cancer | Preventive Measures |
|---|---|---|
| Smoking and Tobacco Use | Increases risk by 2-fold | Quit smoking, avoid tobacco products |
| Obesity and Diet | Elevates hormone-related cancer risk | Maintain healthy weight, adopt balanced diet |
| High Blood Pressure | Damages kidneys, facilitates cancer development | Monitor and manage blood pressure |
How Kidney Cancer Is Diagnosed
Diagnosing kidney cancer is a detailed process. It starts with a doctor’s visit and ends with advanced tests. Each step is important for making a good treatment plan.
Medical History and Physical Exam
Doctors first look at your medical history to spot kidney cancer signs. They ask about symptoms, family health, and other health issues. Then, they check your body for any unusual lumps or changes in the abdomen.
Imaging Tests
Imaging tests are key in finding kidney cancer. Doctors use ultrasound, CT scans, and MRIs to see the kidneys clearly. These tests show the size, shape, and where tumors are. This helps doctors start treating kidney cancer right away.
| Test Type | Purpose | Advantages |
|---|---|---|
| Ultrasound | Initial detection and assessment | Non-invasive, readily available |
| CT Scan | Detailed cross-sectional imaging | High accuracy |
| MRI | Detailed imaging without radiation | Effective for soft tissue evaluation |
Biopsy Procedures
A biopsy is done for a sure diagnosis. It takes a small piece of kidney tissue for a closer look. Thanks to new needle biopsy methods, it’s less painful.
Cytologists check the tissue for cancer cells. This is key to picking the best treatment for kidney cancer.
Treatment Options for Kidney Cancer
Kidney cancer treatment depends on the disease stage, the patient’s health, and other factors. It’s important to know about each option to make good choices.
Surgical Treatments
Surgery is often the first step for kidney cancer, especially for early-stage tumors. There are two main types of surgery:
- Partial nephrectomy (nephron-sparing surgery): This removes the tumor and a bit of healthy tissue, keeping most of the kidney.
- Radical nephrectomy: This surgery takes out the whole kidney, some tissues, and maybe lymph nodes. It’s used for big tumors or those that spread nearby.
Radiation Therapy
Radiation therapy is sometimes used, especially when surgery isn’t possible or as a second treatment. It uses beams of energy to kill cancer cells and shrink tumors.
Targeted Therapy
Targeted therapy is a newer way to treat kidney cancer. It targets specific molecules that help cancer grow. This can slow cancer growth with fewer side effects than traditional chemotherapy. Some drugs used in targeted therapy are:
- Sunitinib (Sutent)
- Bevacizumab (Avastin)
- Cabozantinib (Cabometyx)
Each treatment has its own benefits and risks. A team of doctors will help pick the best treatment for you.
| Treatment Option | Indication | Benefits | Risks |
|---|---|---|---|
| Partial Nephrectomy | Localized Tumors | Preserves Kidney Function | Surgical Risks, Complications |
| Radical Nephrectomy | Larger Tumors | Complete Removal of Cancer | Loss of Kidney |
| Radiation Therapy | Non-surgical Candidates | Non-invasive | Potential Damage to Surrounding Tissues |
| Targeted Therapy | Advanced Cancer | Focus on Cancer Cells | Side Effects, Resistance |
Kidney Cancer Prognosis
The kidney cancer prognosis depends on many things. This includes the cancer’s stage and type, the patient’s health, and how well treatment works. Finding cancer early and treating it well can really help.
Survival rates are better for early-stage kidney cancer. The American Cancer Society says the 5-year survival rate is about 93% for localized kidney cancer. But, survival rates go down as the cancer gets worse. It’s important to get regular check-ups and follow kidney cancer prevention tips to find problems early. Understanding Kidney
Some patients can go into remission and stay that way. But, some may have the cancer come back. It’s important to keep an eye on your health and follow up with your doctor to lower the risk of recurrence. Understanding Kidney
