Cervical cancer occurs when abnormal cells on the cervix camera.gif grow out of control. The cervix is the lower part of the uterus that opens into the vagina. Cervical cancer can often be successfully treated when it's found early. It is usually found at a very early stage through a Pap test.
The superior vena cava is a major vein in a person's body. It carries blood from the head, neck, upper chest, and arms to the heart. Superior vena cava syndrome (SVCS) occurs when a person's superior vena cava is partially blocked or compressed. Cancer is usually the main cause of SVCS.
Lack of sunshine causes skin cancer, according to Andreas Moritz. In this video from 2009, he explains why being in the sun is actually good for you and your skin. Find out why your sunscreen is doing more harm than good. Also, you need vitamin D to prevent cancer, and sunscreen may interfere with your exposure to vitamin D from the sun.
A man set to become the world’s first head transplant patient has scheduled the procedure for December 2017. Valery Spiridonov, 30, was diagnosed with a genetic muscle-wasting condition called Werdnig-Hoffmann disease, and volunteered for the procedure despite the risks involved, Central European News (CEN) reported. “When I realized that I could participate in something really big and important, I had no doubt left in my mind and started to work in this direction,” Spiridonov, a Russian computer scientist, told CEN. “The only thing I feel is the sense of pleasant impatience, like I have been preparing for something important all my life and it is starting to happen.”
Although individual surgeons and centers employ different methods to insert a left ventricular assist device (LVAD), the fundamental concepts remain true for all. That is, most devices use the apex of the left ventricle (LV) as the inflow site to the pump, which subsequently gives off an outflow graft to the aorta, thus bypassing the ailing LV. Currently available devices do not differ significantly with regard to general implantation technique. The sequence of implantation can vary also from patient to patient, depending on the particular situation. In some cases, concomitant procedures may be performed in conjunction with LVAD implantation without adversely affecting outcome.
The cause for TS is unknown. Early research suggested that TS is an inherited condition (often, the person's near or distant relatives have had some form of transient or chronic tic disorder or associated symptoms). Recent studies point to a combination of environmental and genetic factors as a cause of the disorder. The specific genes involved in the development of TS are still being investigated. Studies suggest that TS has a neurological basis and results from an abnormality which affects the brain's metabolism of certain neurotransmitters (chemicals in the brain that regulate behavior.) Current research being funded by the Tourette Syndrome Association (TSA) will help provide more information about the causes and genetic factors of TS.
Pancreatic cysts are saclike pockets of fluid on or in your pancreas, a large organ behind the stomach that produces hormones and enzymes that help digest food. Most pancreatic cysts aren't cancerous, and many don't cause symptoms. They're typically found during imaging testing for another problem. Some are actually noncancerous (benign) pockets of fluids lined with scar or inflammatory tissue, not the type of cells found in true cysts (pseudocysts). But some pancreatic cysts can be or can become cancerous. Your doctor might take a sample of the pancreatic cyst fluid to determine if cancer cells are present. Or your doctor might recommend monitoring a cyst over time for changes that indicate cancer.
