What is heart disease

Heart Disease Cardiovascular disease can be referred to several conditions: Heart disease also known as heart and blood vessel disease contains several issues, many of which is connected to a process called atherosclerosis. Atherosclerosis is a condition that develops when a substance called plaque builds up in the wall of the arteries. This buildup causes the passageway of the arteries to become smaller, as a result, blood cells find it more difficult squeeze pass. This can result in a heart attack or stroke. Heart attack happens when the blood flow to a part of the heart is blocked, usually by blockage caused by buildup of blood clot. If the blockage become large enough to completely cuts off the supplies of the blood, the muscle of the heart connected to that artery starts to die. Although many people survive their first heart attack and recovered enough to enjoy their normal lives, experiencing a heart attack does mean that you need to make some life adjustment. The medications and lifestyle adjustment that your doctor recommends may vary depending on how badly damaged your heart was and the degree of impact heart disease caused the heart attack. Stroke is similar to heart attack in term of the process which the artery is blocked by the buildup of blood clot but is directed to the brain instead of the heart. When the brain cell that is starved of oxygen dies, this can leave a

Cancer Detection

Cancer Detection The process of detecting cancer takes many steps. It may be discovered when the patient goes to a doctor because of other reason, by chance or from screening. However, the final test to determine if a patient has cancer is mainly based on a pathologist’s verification. The most common methods for detecting cancer is through the process of radiological imaging. This process is also use for monitoring the spread of cancer and progress of treatment. Different imaging techniques are used to test for the most optimal treatment, as every patient are unique. The lists below are the imaging methods used to detect cancer in no particular order. Magnetic Resonance Imaging (MRI) is a process of using powerful magnetic fields to detect cancer or sarcoma around the head and neck region. Computed Tomography (CT) is the most common method of detecting cancer. CT scans are made using X-rays. Ultra sound examination is the method of choice when examining lower parts of the body such as liver, kidney and the cervix. Endoscopic examinations are often use for examining the gastrointestinal tract, prostrate, bladder or head and neck areas. Positron Emission Tomography (PET) In this method, the patients are given a radioactive tracker that is detectable by scintigraphy. It is based on the quicker metabolic rate of cancer cells in comparison to normal cells. This method can also be used in combination with CT. Mammography uses X-ray image in breast cancer
