kidney cancer or kidney cancer usually occurs in older people and makes about 2-3% of cancers in adults and affects about twice as many men as women. In adults, the most common type of kidney cancer renal cell carcinoma, which begins in the cells that line the small tubes in the kidneys. Kidney cancer rarely affects children and young adults, with the exceptions of a pediatric kidney cancer called Wilms’ tumor syndrome and some forms of hereditary kidney cancer, as von Hippel-Lindau

.
Causes of kidney cancer
The causes are unknown, but external factors such as smoking and obesity with an increased incidence of kidney cancer and changes in environmental factors and aging population has increased in the submission of this form of cancer.

Signs and symptoms
Kidney cancer symptoms are often overlooked because the tumors usually grow slowly and never suspected until the patient begins to symptoms such as blood in the urine, pain, fatigue and weight palpable experience. Because back pain common in people over 40 years, the pain is often ignored and the presence of kidney cancer can go undetected. Kidney cancer may also cause hypertension.

Risk Factors
The risk of kidney cancer is four times higher if a relative has had kidney cancer. Being on dialysis for many years is a risk factor for kidney cancer.

People who had bladder cancer, kidney cancer, rather, to develop and vice versa. About three percent of patients with kidney cancer have a defective gene, it is likely that cancer is found in her second kidney is inherited.

prevention
No smoking is the most effective way to prevent kidney cancer and it is estimated that the elimination of smoking would be the rate of renal pelvis cancer by half and the rate of renal cell carcinoma reduce third.

Other factors include the risk of developing kidney cancer, decrease the maintenance of normal body weight, a diet rich in fruits and vegetables, especially bananas and root vegetables such as carrots, maintain normal blood pressure and limited exposure to environmental toxins.

Diagnosis of kidney cancer
Kidney cancer is usually detected with either computed tomography (CT), ultrasound or magnetic resonance imaging (MRI). cystoscopy can rule out, by bladder cancer. Kidney cancer cells may also, from the original tumor and spread (or metastasize) to other parts of the body like lymph nodes, bones or lungs, with about a third of the cases in which metastasis at diagnosis.

Types of kidney cancer
Almost 85% of these tumors are renal cell carcinomas. A rare type of kidney papillary carcinoma. Other rare kidney cancer are: Renal sarcoma, collecting ductal carcinoma, medullary carcinoma and chromophobe

.

treatment
can radical nephrectomy with or without removal of lymph nodes offers the only cure, but the treatment of kidney cancer surgery, arterial embolization, radiation therapy, chemotherapy or biological therapy include depends on the stage of the disease and the patient’s overall health.

Nephrectomy or removal of the entire institution, including the adrenal gland, adjacent lymph nodes and the surrounding normal tissue has the standard, but newer research shows that removal of only the tumor, survival rates produced similar offers less chance of kidney failure in later some cases.

Scientists have also isolated the gene responsible for VHL, and this discovery offers exciting possibilities for the future to improve the diagnosis and treatment of certain cancers of the kidney. Different combinations of interleukin-2, interferon and other biological agents and even vaccines developed from cells of kidney cancer also examined.

Survival
With prompt and appropriate treatment, the mortality rate of kidney cancer is relatively low, the kidney cancer is an unfortunate tendency to early dissemination, particularly in the lungs, sometimes until symptoms develop. The survival rate after five years, about 90-95% for tumors smaller than 4 cm. For larger tumors confined to the kidney without venous invasion, survival is still relatively good at 80-85%. If it has metastasized to the lymph nodes, the 5-year survival rate of about 5% to 15%. If it has spread to metastases in other organs, the survival rate after 5 years, less than 5%.

An important factor for those who have this form of cancer and also with all types of cancer is that patients who are working actively to increase firepower to defeat cancer often survival, live longer and enjoy life.
