Who Needs an Upper Endoscopy?
Who Needs an Upper Endoscopy? samer kareem 4,104 Views • 2 years ago

When is endoscopy used? Endoscopes were first developed to look at parts of the body that couldn’t be seen any other way. This is still a common reason to use them, but endoscopy now has many other uses too. It’s often used in the prevention, early detection, diagnosis, staging, and treatment of cancer. To prevent and screen for cancer Some types of endoscopes are used to look for cancer in people who have no symptoms. For example, colonoscopy (KO-lun-AH-skuh-pee) and sigmoidoscopy (SIG-moid-AH-skuh-pee) are used to screen for colon and rectal cancer. These procedures can also help prevent cancer because they let doctors find and remove polyps (growths) that might become cancer if left alone. To find cancer early Endoscopy can sometimes be used to find cancer early, before it has had a chance to grow or spread. Looking for causes of symptoms When people go to the doctor with certain symptoms, endoscopy can sometimes be used to help find a cause. For instance: Laryngoscopy to look at the vocal cords in people with long-term hoarseness Upper endoscopy in people having trouble swallowing Colonoscopy in people with anemia (low red blood cell counts) with an unknown cause Colonoscopy in people with blood in their stool Looking at problems found on imaging tests Imaging tests such as x-rays and CT scans can sometimes show physical changes within the body. But these tests may only give information about the size, shape, and location of the problem. Doctors use endoscopes to see more details, like color and surface texture, when trying to find out what’s going on. Newer methods of endoscopy that include high magnification are being tested to find out whether they are more useful in detecting cancer and other abnormal cells on the inner surfaces of the body. To diagnose and find out the stage (extent) of cancer To get a tissue sample Going one step further, most types of endoscopes have tools on the end that the doctor can use to take out small tissue samples. This procedure is called a biopsy (BY-op-see). Samples can be taken from suspicious areas and then looked at under a microscope or tested in other ways to see if cancer is there. A biopsy is usually the best way to find out if a growth or change is cancer or something else. Getting a closer look In some cases endoscopes are used to help find out how far a cancer has spread. Thoracoscopy (THOR-uh-KAHS -kuh-pee) and laparoscopy (LAP-uh-RAHS-kuh-pee) can be very useful in finding out if cancer has spread into the thorax (chest) or abdomen (belly). The surgeon can look into these places making only a small incision (cut) in the skin.

HIV / AIDS
HIV / AIDS samer kareem 2,677 Views • 2 years ago

HIV stands for human immunodeficiency virus. If left untreated, HIV can lead to the disease AIDS (acquired immunodeficiency syndrome). Unlike some other viruses, the human body can’t get rid of HIV completely. So once you have HIV, you have it for life. HIV attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections. If left untreated, HIV reduces the number of CD4 cells (T cells) in the body, making the person more likely to get infections or infection-related cancers. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS, the last state of HIV infection. No effective cure for HIV currently exists, but with proper treatment and medical care, HIV can be controlled. The medicine used to treat HIV is called antiretroviral therapy or ART. If taken the right way, every day, this medicine can dramatically prolong the lives of many people with HIV, keep them healthy, and greatly lower their chance of transmitting the virus to others. Today, a person who is diagnosed with HIV, treated before the disease is far advanced, and stays on treatment can live a nearly as long as someone who does not have HIV.
