Kidney cancer
Kidney cancer is a type of cancer that originates in the kidneys, two bean-shaped organs located behind the abdominal organs. Renal cell carcinoma is the most common form of kidney cancer in adults, while Wilms tumor is more prevalent in children. The increasing number of kidney cancer diagnoses can be attributed, in part, to the wider use of imaging techniques like CT scans, which may lead to the incidental discovery of small, localized tumors.
Symptoms
Signs and Symptoms
- Blood in the urine: This can appear pink, red, or cola-colored.
- Loss of appetite: Decreased interest in food or difficulty eating.
- Pain in the side or back: A persistent pain in the flank area, often on one side of the body.
- Fatigue: Feeling unusually tired or weak.
- Unexplained weight loss: Losing weight without making any changes to your diet or exercise routine.
Causes
- Smoking: Smoking is a significant risk factor for kidney cancer, nearly doubling your risk compared to non-smokers.
- Exposure to chemicals: Workplace exposure to certain chemicals, such as arsenic, metal degreasers, cadmium, and those used in mining, welding, farming, and painting, can increase the risk of kidney cancer.
- Family history: Having a family member with kidney cancer can elevate your risk.
- Obesity: Being overweight or obese is associated with an increased risk of kidney cancer.
- High blood pressure: Chronic high blood pressure can contribute to the development of kidney cancer.
Risk Factors
- Age: The risk of kidney cancer increases with age.
- Smoking: Smoking is a significant risk factor for kidney cancer, nearly doubling your risk compared to non-smokers.
- Obesity: Being overweight or obese is associated with an increased risk of kidney cancer.
- High blood pressure: Chronic high blood pressure can contribute to the development of kidney cancer.
- Inherited conditions: Certain inherited conditions, such as von Hippel-Lindau disease, Birt-Hogg-Dube syndrome, tuberous sclerosis complex, hereditary papillary renal cell carcinoma, and familial renal cancer, can increase the risk of kidney cancer.
- Family history: Having a family member with kidney cancer can elevate your risk.
Complications
- Spread of the cancer (metastasis): Kidney cancer can spread to other organs, such as the lungs, liver, or bones. This can cause pain, difficulty breathing, and other serious health problems.
- High blood pressure (hypertension): Kidney cancer can affect kidney function, leading to high blood pressure.
- Hypercalcemia: In some cases, kidney cancer can cause elevated calcium levels in the blood, leading to symptoms like fatigue, weakness, and confusion.
- Polycythemia: Kidney cancer can sometimes cause the body to produce too many red blood cells, leading to complications such as blood clots and stroke.
Prevention
- Quit smoking: Smoking is a major risk factor for kidney cancer. Quitting smoking can significantly reduce your risk.
- Maintain a healthy weight: Obesity is associated with an increased risk of kidney cancer. Aim for a healthy weight through a balanced diet and regular exercise.
- Control high blood pressure: High blood pressure can contribute to kidney cancer risk. Work with your healthcare provider to manage your blood pressure.
- Limit exposure to chemicals: If your job involves exposure to harmful chemicals, take precautions to minimize your exposure.

Prostate Cancer Screening Guidelines
The decision to undergo prostate cancer screening is a personal one that should be discussed with your healthcare provider. Here are general guidelines based on risk factors:
- Average Risk: For men with an average risk of prostate cancer and a life expectancy of at least 10 years, screening can begin at age 50.
- High Risk: Men at high risk, including African Americans and those with a family history of prostate cancer in a first-degree relative diagnosed before age 65, may consider starting screening at age 45.
It’s important to note that these are general recommendations, and your individual risk factors may influence the timing of screening.
Factors to Consider When Making Screening Decisions:
- Personal preferences: Discuss your concerns and preferences with your healthcare provider.
- Life expectancy: If you have a life expectancy of less than 10 years, the benefits of screening may outweigh the risks.
- Risk factors: Consider your individual risk factors, such as family history and race.
