What Is Cancer?
Cancer is really a group of many associated illness that all involve cells. Cells are the really small units that comprise all living things, consisting of the human body. There are billions of cells in everyone's body.
Cancer takes place when cells that are not regular grow and spread extremely quickly. Regular body cells grow and divide and know to stop growing. Gradually, they likewise die. Unlike these normal cells, cancer cells simply continue to grow and divide out of control and do not die when they're supposed to.
Cancer cells normally group or clump together to form growths (state: TOO-mers). A growing tumor becomes a swelling of cancer cells that can damage the normal cells around the tumor and damage the body's healthy tissues. This can make somebody really sick.
Sometimes cancer cells break away from the initial growth and travel to other locations of the body, where they keep growing and can go on to form new tumors. This is how cancer spreads. The spread of a growth to a brand-new location in the body is called metastasis (say: meh-TASS-tuh-sis).
Causes of Cancer
You most likely understand a kid who had chickenpox-- perhaps even you. But you probably do not understand any kids who have actually had cancer. If you packed a large football arena with kids, most likely just one child in that stadium would have cancer.
Medical professionals aren't sure why some individuals get cancer and others don't. They do know that cancer is not contagious. You can't capture it from somebody else who has it-- cancer isn't brought on by germs, like colds or the flu are. So do not be scared of other kids-- or anybody else-- with cancer. You can talk to, play with, and hug someone with cancer.
Kids can't get cancer from anything they do either. Some kids believe that a bump on the head triggers brain cancer or that bad individuals get cancer. This isn't true! Kids don't do anything wrong to get cancer. However some unhealthy routines, specifically cigarette smoking cigarettes or drinking excessive alcohol every day, can make you a lot most likely to get cancer when you become an adult.
Discovering Out About Cancer
It can take a while for a medical professional to find out a kid has cancer. That's because the symptoms cancer can cause-- weight reduction, fevers, inflamed glands, or feeling extremely tired or sick for a while-- typically are not brought on by cancer. When a kid has these issues, it's typically triggered by something less severe, like an infection. With medical testing, the doctor can determine what's causing the difficulty.
If the medical professional believes cancer, he or she can do tests to figure out if that's the problem. A physician might purchase X-rays and blood tests and advise the individual visit an oncologist (say: on-KAH-luh-jist). An oncologist is a medical professional who takes care of and treats cancer patients. The oncologist will likely run other tests to learn if someone truly has cancer. If so, tests can identify what sort of cancer it is and if it has actually infected other parts of the body. Based on the results, the doctor will decide the best way to treat it.
One test that an oncologist (or a surgeon) might carry out is a biopsy (say: BY-op-see). Throughout a biopsy, a piece of tissue is gotten rid of from a growth or a location in the body where cancer is suspected, like the bone marrow. Don't worry-- someone getting this test will get special medicine to keep him or her comfortable during the biopsy. The sample that's collected will be analyzed under a microscopic lense for cancer cells.
The faster cancer is discovered and treatment starts, the much better somebody's opportunities are for a complete healing and cure.
Treating Cancer Carefully
Cancer is treated with surgery, chemotherapy, or radiation-- or sometimes a combination of these treatments. The choice of treatment depends on:
Surgery is the oldest type of treatment for cancer-- 3 out of every 5 people with cancer will have an operation to remove it. During surgery, the physician tries to get as many cancer cells as possible. Some healthy cells or tissue may also be removed to make sure that all the cancer is gone.
Chemotherapy (say: kee-mo-THER-uh-pee) is making use of anti-cancer medicines (drugs) to treat cancer. These medicines are sometimes taken as a pill, but typically Get more information are provided through a special intravenous (say: in-truh-VEE-nus) line, also called an IV. An IV is a tiny plastic catheter (straw-like tube) that is put into a vein through someone's skin, usually on the arm. The catheter is attached to a bag that holds the medicine. The medicine flows from the bag into a vein, which puts the medicine into the blood, where it can travel throughout the body and attack cancer cells.
