Transcript of Cancer

Cancer, a serious disease Catherine, Ada, Sabrina Introduction One thing we all know, is that cancer is a scary word and also a very serious disease. Scientists and doctors have done a lot of research, and their hard work paid off. They found some ways to treat cancer, however, no one really found out a way to actually cure it. And with that said, there are still many other things that people have not found out about cancer. This is why everyone is working so hard to figure out some new things that none has discovered yet. But anyways, we're here today to discuss with you about cancer and it's treatments. What is Cancer? Bizarre fact(s): You probably know someone who has gotten a cold or the chicken pox before -- maybe even yourself! These kind of illnesses can be contagious. But this doesn't go the same way for cancer. Cancer isn't contagious, and does not involve any kind of virus. Instead, cancer happens when cells that aren't normal grow and spread around the body. Unlike normal cells, which know when to stop growing and die, these cancer cells just keep spreading without knowing when to stop and die. They eventually go out of control. Cancer cells often clump together to form what's known commonly as tumors. A growing tumor can destroy the normal cells around it and also damage the body's healthy tissues. This can make someone very sick. Sometimes, to make things even worse, cancer cells can break away from the original tumor and travel to other areas of the body, in which they could cause new tumors to form. The spread of a tumor is called metastasis. Video: Treatments for cancer Surgery Surgery is the oldest form 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.
Before surgery, however, a doctor called an anesthesiologist will make sure that the person is asleep during the operation. This medicine also prevents them from feeling any pain while to operation is happening. Chemotherapy Chemotherapy is the use of anti cancer medicines to treat cancer. These medicines are sometimes taken as a pill or an injection (shot), but usually, it's given through a special intravenous line, also called an IV line. An IV is a small plastic catheter (straw like tube thing) that is put through someone's vein, usually on the hand or arm. The line is attached to a bag or pump which puts the medicine in the blood, where it can travel throughout the body and attack the cancer cells. Radiation Radiation is a process in which the energy is given off in the firm of particles or rays. For example, the sun gives out one kind of radiation.
But the radiation therapy is also one form of treating cancer. Radiation can be given in 2 ways. A person may get external radiation, meaning that the radiation is directed to the outside of the body, or they may receive internal radiation, which is directed to the inside of one's body. The doses of radiation are small, but they are also strong enough to kill all the cancer cells. Breaks from radiation give normal cells a chance to grow back and recover. Here are some pictures of cancer cells~ Leukemia cells Breast cancer cells hodgkin's disease cells Lung cancer cells Remission Remission is a good word for anyone who has cancer. It means that all the signs of cancer are gone from the body. After surgery, chemotherapy or radiation, the doctor will do tests to see if the cancer is still there, and if there are no signs of cancer, then the person is in remission. remission is the goal when any person goes to the hospital for treatment. Sometimes, this means additional chemotherapy might be needed for a while to keep cancer cells from coming back. And luckily, for many people, continued remission is the very happy ending of their cancer experience. Good news The number of people who beat cancer goes up each year because of new treatments. The researchers do their best to come up with a way to get rid of cancer for good. We could help them by donating money to them, but in the meantime, let's be thankful for all those researchers who work so hard to put cancer in it's place. THE END! Some kinds of common cancers include: -Leukemia
-Brain cancer
- Lymphoma
-Osteosarcoma
-Hodgkin's disease
-lung cancer Benign tumors are also considered to be normal tumors, however, unlike malignant tumors, they do not spread and are non cancerous. They are also less dangerous than malignant tumors. The two main kinds of tumors Malignant tumors Benign Tumors Malignant tumors are cancerous tumors that grow faster at a rate than a benign tumor. It also spreads to other body parts and can result in death.
