Can You Spot The Symptoms Of Renal Cell Carcinoma
The kidneys are some of the most hardworking organs in the body. Kidneys are responsible for a variety of different jobs including filtering a huge amount of toxic substances out of the body through urine. Kidneys keep the bloodstream healthy and balanced. However, like most aspects of the body, the kidney are a potential growth location for cancer.
Renal cell carcinoma is the most common form of kidney cancer. Nine out of every ten reports cases of kidney cancer turn out to be renal cell carcinoma. While documented cases of kidney cancer seem to be increasing, its potentially simply due to CT scans being used for more issues and allowing kidney cancer to be spotted accidentally. The earlier kidney cancer is discovered, the more viable treatment options become.
How Common Is Renal Cell Carcinoma
Renal cell carcinoma accounts for almost all kidney cancers.
- Renal cell carcinoma accounts for about 8% of all malignant tumors of the kidney. It most commonly occurs in teens and young adults. In adults, there are about 64,000 new cases each year.
- Renal cell carcinoma is rare in children younger than 15. In teens ages 15 to 19, renal cell carcinomas represent two-thirds of all kidney cancers.
Metastatic Renal Cell Carcinoma Diagnosis
This type of cancer can produce a variety of symptoms including pain fatigue and blood in the urine. On imaging they have a variety of radiographic appearances from solid.

The Following Stages Are Used For Renal Cell Cancer:
In stage III, one of the following is found:
- the cancer in the kidney is any size and cancer has spread to nearby lymph nodes or
- cancer has spread to blood vessels in or near the kidney , to the fat around the structures in the kidney that collect urine, or to the layer of fatty tissue around the kidney. Cancer may have spread to nearby lymph nodes.
In stage IV, one of the following is found:
- cancer has spread beyond the layer of fatty tissue around the kidney and may have spread into the adrenal gland above the kidney with cancer or to nearby lymph nodes or
- cancer has spread to other parts of the body, such as the bones, liver, lungs, brain, adrenal glands, or distant lymph nodes.
What Are Causes And Risk Factors Of Renal Cell Carcinoma
The exact cause of renal cell cancer has not been determined. A number of different factors seem to contribute to renal cell cancer. These risk factors include the following:
- Cigarettesmoking doubles the risk of renal cell cancer and contributes to as many as one third of all cases. The more someone smokes, the greater the risk is of that person developing renal cell cancer.
- Obesity is a risk factor. As body weight increases, so does the risk of developing renal cell cancer. This is especially true in women.
- Occupational exposure to petroleum products, heavy metals, solvents, coke-oven emissions, or asbestos
- Cystic kidney disease associated with chronic renal insufficiency
- Cystic changes in the kidney and renal dialysis
- Tuberous sclerosis
In its early stages, renal cell cancer usually causes no noticeable symptoms. Symptoms may occur only when the cancer grows and begins to press on surrounding tissues or spread to other parts of the body. The symptoms vary considerably from person to person. Some people never develop any symptoms before the disease is discovered the cancer is found when they undergo imaging tests, such as a CT scan, for another reason. In a study in the Journal of Urology, approximately 53% of people with localized renal cell carcinoma had no symptoms.
Signs and symptoms of renal cell cancer may include the following:
- Weight loss
- Night sweats

Clear Cell Renal Cell Carcinoma
Clear cell renal cell carcinoma, also known as ccRCC or conventional renal cell carcinoma, is a the most common form of kidney cancer. Clear cell renal cell carcinoma is named after how the tumor looks under the microscope. The cells in the tumor look clear, like bubbles.
In adults, ccRCC makes up about 80% of all renal cell carcinoma cases. ccRCC is more common in adults than children. Renal cell carcinoma makes up 2% to 6% of childhood and young adult kidney cancer cases.”
Symptoms Of Renal Cell Carcinoma
cases of kidney cancer. RCC usually manifests as one tumor, but it may include two tumors. If there are two, they can both be in the same kidney or there can be one tumor in each.
Risk factors for this type of cancer include:
- a family history of RCC
- some hereditary kidney diseases, such as polycystic kidney disease
Surgical treatment for RCC is often recommended, depending on what stage the cancer is at. The survival rate is fairly high if the cancer is caught early, with a five-year survival rate of

Renal Cell Carcinoma Symptoms
Early renal cell carcinoma do not usually cause any signs or symptoms, but larger ones might. Some possible signs and symptoms of kidney cancer include:
- Blood in the urine
- Low back pain on one side
- A mass on the side or lower back
- Weight loss not caused by dieting
- Fever that is not caused by an infection and that doesnt go away
These signs and symptoms can be caused by renal cell carcinoma , but more often they are caused by other, benign, diseases. For example, blood in the urine is most often caused by a bladder or urinary tract infection or a kidney stone. Still, if you have any of these symptoms, see a doctor so that the cause can be found and treated, if needed.
What Are The Types Of Kidney Cancer
The information in this document refers to renal cell carcinoma the most common form of kidney cancer. However, there are different types of kidney cancer, including:
- Renal cell carcinoma : This is the most common form of kidney cancer in adults and accounts for 85% of all kidney cancers. Renal cell carcinoma usually develops as a single tumor in one kidney, but it can affect both kidneys. Renal cell carcinoma begins in the cells that line the small tubes that are part of the nephrons within the kidneys. .
- Transitional cell carcinoma: Transitional cell carcinoma accounts for 6% to 7% of all kidney cancers. This cancer usually begins in the area where the ureter connects to the main part of the kidney. This area is called the renal pelvis. Transitional cell carcinoma also can occur in the ureters or bladder.
- Renal sarcoma: This is the least common form of kidney cancer, accounting for only 1% of kidney cancer cases. It begins in the connective tissues of the kidneys and, if not treated, can spread to nearby organs and bones.
- Wilms’ tumor: This is the most common type of kidney cancer in children. It accounts for about 5% of kidney cancers.

How Renal Cell Carcinoma Spreads
Renal cell carcinoma can spread from the kidney to other areas of the body. It can enlarge within the kidney and grow into the adrenal glands, which are adjacent to the kidneys. Adrenal glands are small organs that make and release hormones. Each kidney has one adrenal gland located right above it.
Cancer cells can also enter into the bloodstream or the lymphatic vessels, spreading to other areas of the body. The cancer can then grow in other organs, such as the lungs, bones, or brain, causing serious harm to these areas.
Targeted Therapies For Renal Cell Carcinoma
As researchers have learned more about the molecular and genetic changes in cells that cause cancer, they have developed newer drugs that target some of these changes. These targeted drugs are different from standard chemotherapy drugs. They sometimes work when standard chemo drugs dont, and they often have different side effects.
Targeted drugs are proving to be especially important in renal cell carcinoma, where chemotherapy has not been shown to be very effective.
When might targeted drugs be used?
Treating advanced renal cell carcinoma
All of the targeted drugs below can be used as to treat advanced renal cell carcinomas. They can often shrink or slow the growth of the cancer for a time, but it doesnt seem that any of these drugs can actually cure renal cell carcinoma.
Targeted drugs are most often used one at a time. If one doesnt work, another can be tried. Its not yet known if any one of these drugs is clearly better than the others, if combining them might be more helpful than giving them one at a time, or if one sequence is better than another. Studies are being done to help answer these questions.
Adjuvant therapy after surgery
Sunitinib can also be used after surgery is done to remove the cancer, to help lower the risk that the cancer will come back. This is known as adjuvant therapy.

Mind & Body Therapies
These combine mental focus, breathing, and body movements to help relax the body and mind. Some examples are:
- Meditation: Focused breathing or repetition of words or phrases to quiet the mind
- Biofeedback: Using simple machines, the patient learns how to affect certain body functions that are normally out of one’s awareness
- Hypnosis: A state of relaxed and focused attention in which a person concentrates on a certain feeling, idea, or suggestion to aid in healing
- Yoga: Systems of stretches and poses, with special attention given to breathing
- Tai Chi: Involves slow, gentle movements with a focus on the breath and concentration
- Imagery: Imagining scenes, pictures, or experiences to help the body heal
- Creative outlets: Interests such as art, music, or dance
Stages Of Kidney Cancer
- Stage I: The tumor is 7 cm across or smaller and is only in the kidney. It has not spread to lymph nodes or other tissue. .
- Stage II: The tumor is larger than 7 cm across but is still only in the kidney. It has not spread to lymph nodes or other tissue.
- Stage III: The tumor has spread to the major blood vessels the renal vein and inferior vena cava or into the tissue surrounding the kidney, or to nearby lymph nodes.
- Stage IV: The tumor has spread outside of the kidney to the adrenal gland , or to distant lymph nodes, or to other organs.
Tumors are also graded, which is a way of rating a tumor based on how abnormal its cells look. Tumor grading can also tell the doctor how fast the tumor is likely to grow. Tumors whose cells do not look like normal cells and divide rapidly are called high-grade tumors. High-grade tumors tend to grow and spread more quickly than low-grade tumors.

What Usually Causes Kidney Cancer
It’s not known exactly, but like other cancers, kidney cancer is caused by gene mutations that are either inherited or acquired during life. Some risk factors that have been identified include smoking, obesity, high blood pressure, and workplace exposure to certain chemicals. Family history also plays a role, and certain genetic conditions are associated with a high risk of kidney cancer.
Renal Cell Carcinoma Tumor Stages
- Stage 1: The tumor is only in the kidney and it is smaller than 7 centimeters in size.
- Stage 2: The tumor is only in the kidney and it is larger than 7 cm in size.
- Stage 3: The tumor has spread beyond the kidney to adjacent areas, such as the adrenal gland.
- Stage 4: the tumor has spread beyond the kidney and adjacent structures to at least one other area of the body.

Causes And Risk Factors Of Renal Cell Carcinoma
Unfortunately, like many forms of cancer, theres no clear cause of why some people get renal cell carcinoma and others dont. There do seem to be some risk factors however. People who have one or more of these risk factors may be more likely to end up having kidney cancer. Risk Factors include:
- Age – People are at a higher risk as they get older
- Obesity – Obesity is a consistent risk factor compared to average weight or fit individuals.
- Smoking – Smoking increases the risks of many forms of cancer including kidney cancer.
- Hypertension – This form of extremely high blood pressure is a known risk factor.
- Family History – People who have a strong connection to renal cell carcinoma through family members are at a higher risk.
- Kidney Failure – The treatment for kidney failure is long-term dialysis. People undergoing this treatment can find themselves at risk.
- Specific Disorders – There are a variety of disorders and syndromes which can increase the risk of renal cell carcinoma.
- Workplace Exposure – There are several different substances like certain herbicides or cadmium which can potentially increase risk.
Ablation And Other Local Therapy For Renal Cell Carcinoma
For people who are too sick to have surgery, other approaches can sometimes be used to destroy renal cell carcinoma. They might be helpful for some people, but there is much less data on how well they work over time than there is for surgery, so they are not yet considered a standard treatment.
This approach uses extreme cold to destroy the tumor. A hollow probe is inserted into the tumor either through the skin or during laparoscopy. Very cold gases are passed through the probe, creating an ice ball at its tip that destroys the tumor. To be sure the tumor is destroyed without too much damage to nearby tissues, the doctor carefully watches images of the tumor during the procedure or measures tissue temperature.
The type of anesthesia used for cryotherapy depends on how the procedure is being done. Possible side effects include bleeding and damage to the kidneys or other nearby organs.
This technique uses high-energy radio waves to heat the tumor. A thin, needle-like probe is placed through the skin and advanced until the end is in the tumor. Placement of the probe is guided by ultrasound or CT scans. Once it is in place, an electric current is passed through the tip of the probe, which heats the tumor and destroys the cancer cells.
Radiofrequency ablation is usually done as an outpatient procedure, using local anesthesia where the probe is inserted. You may be given medicine to help you relax as well.

Symptoms Of Metastatic Renal Cell Carcinoma
Your renal cell cancer might not produce symptoms until it spreads outside your kidney. Your first symptoms may be caused by the effects of metastatic cancer in a different part of your body besides your kidney:
- Back pain can occur due to renal cell carcinoma metastasis to the spine
- Breathing problems or feeling faint can occur due to the spread of renal cell carcinoma to the lungs or heart
- Headaches or weakness on one side of the body
- Behavioral changes, confusion, or seizures can occur if renal cell carcinoma spreads to the brain
