What Is Cancer?
Cancer is really a group of many related illness that all have to do with cells. Cells are the extremely little systems that make up all living things, consisting of the body. There are billions of cells in everyone's body.
Cancer occurs when cells that are not typical grow and spread out very quick. Regular body cells grow and divide and understand to stop growing. In time, they likewise pass away. Unlike these regular cells, cancer cells just continue to grow and divide out of control and don't pass away when they're expected to.
Cancer cells usually group or clump together to form tumors (state: TOO-mers). A growing growth becomes a lump of cancer cells that can ruin the regular cells around the tumor and damage the body's healthy tissues. This can make somebody very ill.
Often 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 transition (say: meh-TASS-tuh-sis).
Reasons for Cancer
You most likely know a kid who had chickenpox-- perhaps even you. However you most likely do not know any kids who've had cancer. If you loaded a big football arena with kids, probably only one kid 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 infectious. You can't catch it from someone else who has it-- cancer isn't brought on by bacteria, like colds or the influenza are. So do not be afraid of other kids-- or anyone else-- with cancer. You can speak with, have fun with, and hug somebody with cancer.
Kids can't get cancer from anything they do either. Some kids think that a bump on the head causes brain cancer or that bad people get cancer. This isn't true! Kids do not do anything incorrect to get cancer. However some unhealthy habits, especially smoking or drinking excessive alcohol every day, can make you a lot most likely to get cancer when you end up being an adult.
Finding Out About Cancer
It can take a while for a physician to determine a kid has cancer. That's due to the fact that the signs cancer can cause-- weight loss, fevers, swollen glands, or feeling excessively exhausted or ill for a while-- generally are not brought on by cancer. When a kid has these problems, it's often caused by something less major, like an infection. With medical screening, the medical professional can find out what's causing the trouble.
If the physician thinks cancer, she or he can do tests to find out if that's the issue. A medical professional might order X-rays and blood tests and recommend the person go to see an oncologist (say: on-KAH-luh-jist). An oncologist is a physician who looks after and deals with cancer clients. The oncologist will likely run other tests to learn if somebody really has cancer. If so, tests can determine what kind of cancer it is and if it has spread to other parts of the body. Based upon the outcomes, the physician will choose the very best method to treat it.
One test that an oncologist (or a cosmetic surgeon) may carry out is a biopsy Click here (say: BY-op-see). During a biopsy, a piece of tissue is removed from a growth or a place in the body where cancer is presumed, like the bone marrow. Do not 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 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 physician tries to get as numerous cancer cells as possible. Some healthy cells or tissue might likewise 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 medications are in some cases taken as a tablet, 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 put into a vein through someone's skin, normally on the arm. The catheter is connected 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.
