Kidney cancer originates in the kidneys. It usually happens when the healthy cells in either or both your kidneys become cancerous and form a tumor or lump. As it usually does not show any signs or symptoms, it may go undetected until it has advanced. However, there are a few preventive measures for kidney cancer, which can reduce your risk of developing it. 

• Quit smoking
  Smoking is the number one risk factor for kidney cancer. Thus, if you are someone who smokes, you need to stop immediately. If you are unable to quit, you can seek help and opt for nicotine replacement alternatives. Also, it will help if you speak to your doctor about ways to stop. You can take prescription medication to curtail your cravings or enroll yourself in a cessation program. When you quit smoking, your kidney function improves. The primary role of the kidney is to filter out the toxins and the waste from your bloodstream. Cigarettes have several toxins in them. So, the more you smoke, the difficult it gets for your kidneys. 

• Maintain an optimum body weight
  If you are overweight, you need to take immediate steps to maintain your body weight. It could mean reducing your overall calorie intake or engaging in physical activities. You can even consult your doctor about a few helpful strategies to shed some weight. Staying physically active will also boost your energy levels and improve your overall stamina and strength. Moreover, exercising strengthens your body immunity and makes it easier for you to fight several infections, even cancer. Physical activity also helps uplift your mood and promote positivity. You can opt for any exercise you will feel motivated to do every day, such as pilates, yoga, aerobics, biking, walking, or swimming. If you are new to exercising, it is best to start slow and then increase your intensity. 

• Try to maintain your blood pressure
  Whenever you visit your doctor, you should get your blood pressure checked. If you have a high BP, you must discuss all the options to keep your blood pressure in check. For maintaining the required pressure, you can engage in a healthy diet, weight loss, and physical activities. Your doctor will be able to help you better with this. It is an essential preventive measure of kidney cancer.
• Curtail your exposure to chemicals
  It is known that chemicals such as cadmium and asbestos and a few industry minerals heighten your risk of kidney cancer. Thus, it is vital to reduce your exposure to these chemicals. Further, if these chemicals are found in your workplace, you must wear a mask while you are working. 

Though these are preventive measures of kidney cancer for people with a high risk of kidney cancer,   they will also help if you already have been diagnosed with kidney cancer.
