The tumor may become quite large, but usually remains self-enclosed. Spread of the tumor to the lungs, liver, bone, or brain is the most worrisome complication. High blood pressure and kidney damage may occur as the result of the tumor or its trea...

Hypertension is the term doctors use for high blood pressure. Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as 2 numbers. For example, 140 over 90 (written as 140/90. The top number is your systolic pressure, the pressure created when your heart beats. It is considered high if it is consistently over 140; The bottom number is your diastolic pressure, the pressure inside blood vessels when the heart is at rest. It is considered high if it is consistently over 90. Either or both of these numbers may be too high. Pre-hypertension is when your systolic blood pressure is between 120 and 139 or your diastolic blood pressure is between 80 and 89 on multiple readings. If you have pre-hypertension, you are more likely to develop high blood pressure at some point. See also: Blood pressure

In populations, blood pressures fit a normal distribution, but the attendant risks of heart disease and stroke increase curvilinearly with increasing levels of blood pressure, without any obvious breakpoint ( Fig. 63-1 ). Thus, the separation of normal from high blood pressure is arbitrary, and the definition of hypertension has been a moving target.

Blood pressure is the force with which blood pushes against the artery walls as it travels through the body. Like air in a balloon, blood fills arteries to a certain capacity- and just as too much air pressure can cause damage to a balloon, too much blood pressure can harm healthy arteries.

Also known as high blood pressure, a condition in which too much force is exerted by the blood as it travels through the body ' s arteries. There are two types of hypertension: primary and secondary.

Hypertension is an independent risk factor for coronary artery disease (CAD) and stroke, leading causes of morbidity and mortality in North America. Concern has been raised that there is inadequate outpatient detection, evaluation, and treatment of hypertension, and that this is resulting in increased hospital admissions with complications of untreated hypertension: heart failure, and end-stage renal disease .

Hypertension is the medical term for high blood pressure. Blood pressure is the force of blood pushing against the walls of arteries as it flows through them.

The National High Blood Pressure Education Program (NHBPEP) was established in 1972 by the National Institute of Health to translate research results on the health hazards of high blood pressure into clinical and public health practice. Before 1900, high blood pressure, or hypertension, was not generally recognized as a health problem.

Acute (sudden) kidney failure is the sudden loss of the ability of the kidneys to remove waste and concentrate urine without losing electrolytes.
|
|
Chronic kidney failure occurs when disease or dis- order damages the kidneys so that they can no longer adequately remove fluids and wastes from the body or maintain proper levels of kidney-regulated chemicals in the bloodstream. Chronic kidney failure, also known as chronic renal failure, affects over 250,000 Americans annually.

Metastasis is the movement or spreading of cancer cells from one organ or tissue to another. Cancer cells usually spread through the bloodstream or the lymph system.
|
|
|
The ability to invade and metastasize are the defining characteristics of a cancer. Invasion refers to the ability of cancer cells to penetrate through the membranes that separate them from healthy tissues and blood vessels.
