What is a biopsy?

In a broader sense, a biopsy understand the process of study biopsy – tissue sections obtained in vivo. Biopsy is mandatory method of confirming the diagnosis in suspected the presence of cancer. A biopsy is the most reliable method of investigation in the case of the need to establish the cellular composition of tissue. Capture of tissues and their subsequent study under a microscope to determine the exact cellular composition of the investigated material. A biopsy is the study within the diagnostic minimum for suspected cancer, and is complemented by other research methods, such as radiological, endoscopic, immunologic.

Hyperkalemia or high potassium level occurs when the level of potassium in your body and blood is higher than normal.
Potassium is a nutrient that is critical to the normal function of nerve, heart and muscles cells. It plays an important role in controlling activity of smooth muscle and skeletal muscle, as well as the muscles of the heart. It is also important for normal transmission of electrical signals throughout the nervous system within the body.
Normal blood potassium level is 3.6 to 4.8 milliequivalents per liter (mEq/L). Having a blood potassium level higher than 6.0 mEq/L can be dangerous and requires immediate treatment. Extremely high levels of potassium in the blood (severe hyperkalemia) can lead to cardiac arrest and death.
