What Is Kidney Cancer and How Does It Affect You?
Oxford University Press says cancer spreads in your kidneys when there is an abnormal growth of cells, which in no time multiply and form a tumor. A cancerous or malignant tumor quickly spread to other tissues and vital organs.
Different types of kidney cancer include:
- Renal cell carcinoma
- Transitional cell cancer
- Kidney sarcoma
- Wilms tumor
How fast does kidney cancer spread?
Research shows that kidney tumors grow an average of 0.3 cm per year. However, the doctors say that growth rates are highly variable and can generally be faster in people who are younger and physically fit.
Different stages of kidney cancer
The different stages of kidney cancer include:
This is the earliest stage of kidney cancer, where the tumor is less than 7 cm in diameter. At this stage, it is usually confined to the kidneys and does not spread to nearby lymph nodes.
Doctors usually say that stage one cancer can be addressed with chemotherapy, radiotherapy, or removing the kidney through a procedure known as nephrectomy.
Stage 2 is more serious than stage 1, where the tumor is larger than 7 centimeters but has not spread to lymph nodes or other organs. Treatment involves removing the cancerous kidney, but follow-up therapy may not be necessary.
The five-year survival rate for stage 2 kidney cancer is 75 percent.
Doctors say that in stage 3, the cancer spreads beyond the kidney and invades nearby lymph nodes, such as the adrenal glands or vena cava, the vein that goes to the heart. Treatment for stage 3 kidney cancer includes surgery, radiation, chemotherapy, and a combination.
According to doctors, the survival rate for stage 3 kidney cancer is about 53 percent.
At stage 4, kidney cancer can be classified into two –
- Tumor grows larger than the kidney and aggressively spreads to other organs and lymph nodes
- Tumor that grows to any size may be in lymph nodes and has spread to other organs or further lymph nodes
According to health experts, the five-year survival rate plummets at this stage to just 8 percent after diagnosis.
Signs and Symptoms
In the early stages, the kidney produces no noticeable symptoms, but as it grows, the signs begin to become more apparent. Some of these are:
- Blood in the urine or hematuria
- A lump or mass around the kidneys
- Fatigue and constant tiredness
- Loss of appetite
- Weight loss
- Mild fever
- Bone pain
- High bloodpressure
- Increase in calcium
