What Is Cancer?
Cancer is actually a group of many related illness that all have to do with cells. Cells are the extremely small units that comprise all living things, consisting of the human body. There are billions of cells in everyone's body.
Cancer happens when cells that are not regular grow and spread very fast. Typical body cells grow and divide and understand to stop growing. With time, they also die. Unlike these regular cells, cancer cells simply continue to grow and divide out of control and don't die when they're expected to.
Cancer cells generally group or clump together to form tumors (say: TOO-mers). A growing growth becomes a lump of cancer cells that can damage the regular cells around the tumor and damage the body's healthy tissues. This can make someone really ill.
Sometimes cancer cells break away from the original tumor and travel to other locations of the body, where they keep growing and can go on to form brand-new tumors. This is how cancer spreads. The spread of a tumor 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've had cancer. If you packed a big football arena with kids, probably only one child because arena would have cancer.
Doctors aren't sure why some people get cancer and others do not. They do understand that cancer is not contagious. You can't catch it from another person who has it-- cancer isn't brought on by germs, like colds or the flu are. So don't hesitate of other kids-- or anybody else-- with cancer. You can talk with, 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 real! Kids don't do anything wrong to get cancer. But some unhealthy practices, specifically cigarette smoking or drinking too much alcohol every day, can make you a lot most likely to get cancer when you end up being a grownup.
Discovering Out About Cancer
It can take a while for a medical professional to figure out a kid has cancer. That's since the signs cancer can trigger-- weight-loss, fevers, inflamed glands, or feeling overly tired or ill for a while-- generally are not brought on by cancer. When a kid has these problems, it's frequently triggered by something less severe, like an infection. With medical testing, the doctor can figure out what's causing the difficulty.
If the physician believes cancer, she or he can do tests to figure out if that's the problem. A doctor may buy X-rays and blood tests and recommend the individual go to see an oncologist (say: on-KAH-luh-jist). An oncologist is a doctor who takes care of and deals with cancer clients. The oncologist will likely run other tests to find out if someone actually has cancer. If so, tests can identify what type of cancer it is and if it has infected other parts of the body. Based upon the results, the doctor will choose the finest way to treat it.
One test Home page that an oncologist (or a surgeon) may 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 place in the body where cancer is believed, like the bone marrow. Don't stress-- somebody getting this test will get special medication to keep him or her comfortable during the biopsy. The sample that's gathered 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 treatment.
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 form of treatment for cancer-- 3 out of every 5 individuals with cancer will have an operation to remove it. During surgery, the physician tries to get as numerous cancer cells as possible. Some healthy cells or tissue may also be eliminated to ensure that all the cancer is gone.
Chemotherapy (say: kee-mo-THER-uh-pee) is making use of anti-cancer medications (drugs) to deal with cancer. These medicines are in some cases taken as a pill, however normally are provided through an unique intravenous (state: in-truh-VEE-nus) line, likewise called an IV. An IV is a small plastic catheter (straw-like tube) that is taken into a vein through somebody's skin, generally on the arm. The catheter is connected to a bag that holds the medication. The medication streams from the bag into a vein, which puts the medication into the blood, where it can take a trip throughout the body and attack cancer cells.
