What Is Cancer?
Cancer is in fact a group of lots of related diseases that all pertain to cells. Cells are the really small systems that comprise all living things, including the human body. There are billions of cells in everyone's body.
Cancer takes place when cells that are not normal grow and spread really quickly. Normal body cells grow and divide and understand to stop growing. With time, they also die. Unlike these typical 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 (say: TOO-mers). A growing tumor ends up being a swelling of cancer cells that can destroy the normal cells around the tumor and damage the body's healthy tissues. This can make somebody really sick.
In some cases cancer cells break away from the initial growth and travel to other areas 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 place in the body is called metastasis (say: meh-TASS-tuh-sis).
Reasons for Cancer
You most likely understand a kid who had chickenpox-- maybe even you. But you most likely do not understand any kids who've had cancer. If you packed a big football arena with kids, most likely only one child in that arena would have cancer.
Medical professionals aren't sure why some people get cancer and others don't. They do know that cancer is not infectious. You can't capture it from somebody else who has it-- cancer isn't triggered by germs, like colds or the influenza are. So do not be scared of other kids-- or anyone else-- with cancer. You can speak with, play with, and hug somebody 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 people get cancer. This isn't true! Kids don't do anything incorrect to get cancer. However some unhealthy routines, especially smoking or drinking too much alcohol every day, can make you a lot more most likely to get cancer when you end up being a grownup.
Learning about Cancer
It can take a while for a doctor to determine a kid has cancer. That's since the signs cancer can trigger-- weight loss, fevers, swollen glands, or feeling overly exhausted or ill for a while-- generally are not triggered 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 might purchase X-rays and blood tests and suggest the individual visit an oncologist (say: on-KAH-luh-jist). An oncologist is a medical professional who looks after and treats cancer patients. The oncologist will likely run other tests to discover if someone truly has cancer. If so, tests can determine what type of cancer it is and if it has Have a peek at this website actually spread out to other parts of the body. Based upon the outcomes, the medical professional will decide the very best way to treat it.
One test that an oncologist (or a surgeon) may perform is a biopsy (say: BY-op-see). During a biopsy, a piece of tissue is eliminated from a growth or a location in the body where cancer is believed, like the bone marrow. Do not stress-- somebody getting this test will get unique medicine to keep him or her comfortable throughout the biopsy. The sample that's collected will be analyzed under a microscopic lense for cancer cells.
The earlier cancer is discovered and treatment starts, the much better somebody's opportunities are for a full recovery 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 doctor tries to take out 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 the use of anti-cancer medicines (drugs) to treat cancer. These medicines are sometimes taken as a pill, but typically are given 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, normally on the arm. The catheter is connected to a bag that holds the medication. 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.
