Kidney cancer can rarely causes signs or symptoms in its early stages. In the later stages, kidney cancer signs and symptoms may include:
• Pain in your back or side that doesn’t go away
• Blood in your urine, which may appear pink, red or cola colored
• Unexplained weight loss

This condition begins in the kidneys. Your kidneys are two bean-shaped organs. Each is about the size of your fist. They’re located behind your abdominal organs with one kidney on each side of your spine. In adults, renal cell carcinoma is the most common type of kidney cancer. Other less common types of kidney cancer can occur. Young children are more likely to develop a kind of kidney cancer called Wilms’ tumor.

Factors that can increase the risk of kidney cancer include:
• Obesity – People who are obese have a higher risk of kidney cancer than people who are considered average weight.
• Older age – your risk of kidney cancer increases as you age.
• High blood pressure – this increases your risk of kidney cancer.
• Smoking – smokers have a greater risk of kidney cancer than nonsmokers do. The risk decreases after you quit.
• Treatment for kidney failure – People who receive long-term dialysis to treat chronic kidney failure have a greater risk of developing kidney cancer.
• Family history of kidney cancer – even in the absence of an inherited syndrome, people who have a strong family history of renal cell cancer have a greater risk of kidney cancer.
• Certain inherited syndromes – people who are born with certain inherited syndromes may have an increased risk of kidney cancer.
• Exposure to certain substances in the workplace -This might include exposure to cadmium or specific herbicides.

How does Pazopanib work?
The way that cells in the body work and grow is regulated by various enzymes called protein kinases. These enzymes can be found in certain receptors on the surface of cells that are involved in the growth and spread of cancer cells.

Pazopanib is a type of medicine known as a protein kinase inhibitor. It works by interfering with the pathways that signal certain cancer cells to grow. In cancerous cells, the kinases make the cells multiply abnormally. They also stimulate nearby blood vessels to grow into the tumor.
The new blood vessels allow the cancer cells to multiply by supplying them with oxygen and nutrients. They also allow the cancerous cells to spread into other areas of the body through the blood circulation. Pazopanib attaches to a certain receptors on cancer cells and cells in blood vessel walls. It blocks the action of the protein kinases. This stops the signals that tell the cancer cells to grow and multiply. It also stops blood vessels growing into the tumor. These effects stop the tumor from growing.
