What is cancer
Cancer is a disease in which abnormal cells divide uncontrollably and destroy body tissue. Cancer starts when cells in a part of the body start to grow uncontrollably. Instead of the cells dying like normal human cells, they continue to grow and make new, abnormal cells. Most cancer cells form a lump or a tumor. Cancer cells can also grow into other tissues, something that normal cells cannot do.
Chemotherapy is the use of drugs or medicine to treat cancer. Radiation therapy uses high energy particles to harm or damage cancer cells. Radiation therapy is one of the most common forms of treatment for cancer patients. Immunotherapy, Hypothermia, and Photodynamic therapy are just an example of the many types of treatments, cancer patients use to defeat cancer.
How Cancer is formed
Cancer is formed when cells in the body start to grow out of control. Cancer cells never stop growing and can also grow into other tissues, something normal cells cannot do. Once the cells divide uncontrollably they form lumps or tumors. Tumors can grow and interfere with the digestive, nervous, and circulatory system.Tumors that stay in one spot and show limited growth are often considered to be benign.
There are many ways you can get cancer. If someone in your family has cancer there is a chance you will get some type of cancer in the future. It is genetically passed down from generation to generation.
Too much sun can also make cancer risk very high. Too much sun can cause skin cancer.
If you smoke you can get lung cancer.
Radiation expose can lead to cancer. All though many cancer patients do use Radiation to help fight cancer. It is called Radiation therapy.
Cancer cells v.s Normal cells
All living organisms are made up of cells. The cells divide and grow in a controlled manner. Any change to these cells could be a start to cancerous cells. Cancer cells and Normal cells differ in many ways.
Normal cells: Ability to reproduce correctly, Stop reproducing when necessary, remain in a specific location, communicate with other cells through chemical signals. These chemical signals notify when to start and to stop reproducing.
Cancer cells: Reproduce uncontrollably, gain control of their own growth signals, they continue to grow unchecked, don't age or die out, lose the ability to communicate to other cells through chemical signals.
1: What can cancer cells do that normal cells cannot?
A) Communicate with other cells

D) Reproduce correctly
2: All organisms are made up of what?
3: What type of cancer can you get when out in the sun for too long?
A) Breast cancer
B) Skin cancer
C) Lung cancer
4: What is a benign tumor?
A) A bunch of bumps that grow on the skin
B) Mass of cells that lack ability to invade neighboring tissue
C) A type of cancer tumor
D) Dots all over the body
5: How is cancer formed?
A) Cells in the body grow out of control
B) Loss of hair
C) No more cells grow out of control
Cancer: A disease caused by an uncontrolled division of abnormal cells in a part of the body.
Chemotherapy: Cancer treatment that uses chemical substances.
Radiation therapy: Using radiation to kill malignant cells.
Immunotherapy: Using your own body's immune system to help battle cancer.
Hypothermia: body is put in high temperature to help kill and damage cancer cells.
photodynamic therapy: using drugs and a particular type of light to kill nearby cells.
Benign: Mass of cells that lack the ability to invade neighboring tissue.
Skin cancer: Abnormal growth of skin cells.
Lung Cancer: A cancer that is formed in the lungs and usually occurs in people who smoke.
Metastasize: The development of secondary malignant growths at a distance from a primary site of cancer.
