Welcome! My name is Sahaara and I am a scientist that recetly discovered a strange cell
Hey look! The cell I discovered is here! I will put her in an examination room and tell her what she is.
Please take a seat while we gather your information.

We have gathered all your information. I will first start by telling you what you do.
You are what we call multicellular. You multiply by number. Normal cells stop multiplying or reproducing when there are enough needed but you, as a cancer cell do not. Instead you keep growing by number and this can create a tumor. These are all things a cancer cell is capable of. Cancer cells don't only make tumors but can also create something called leukaemia. Leukaemia is a type of cancer where cancer cells are in white blood cells. These cancer cells make abnormal white blood cells that mix with normal white blood cells.
Normal cells send chemical signals to each other. These signals usually say to turn on or off a certain gene. Eg. Divide or die. These signals are important because without them there could be to many or to little cells. You on the other hand, as a cancer cell do not get these messages or listen to them. This leads to to many cancer cells that can easily creates tumors. You do however, send signals to blood vessels to grows towards them and when there is a lot of blood flow from the blood vessels, cancer cells enter the blood vessel (Vascular system or respiratory system) and spread to other areas of the body. This is called vascularization. As you can see by these examples you have a lot of differences from normal cells.
