What is the purpose of the cell cycle?
To make sure cells are healthy and grow at the proper rate?
100
How many stages of cancer are there?
4.
100
What is "chemotherapy?"
The drug-based treatment of cancer (or any disease, really).
100
What is a "gene?"
A piece of DNA coding for a particular trait (you have a gene for hair color, or eye color, for example.)

Name three different types of cancer we've discussed.
Let's see them!
200
Special parts of the cell cycle stop the cell to make sure it has grown and developed properly before allowing it to move on. What are these special parts called?
Checkpoints.
200
Define "metastasis."
The spreading of a cancerous tumor throughout the body.
200
What is radiation?
The energy-based treatment of cancer (or any disease, really).
200
A gene is: AATTGCCGA Draw a mutated version of that same gene.
Let's see it!

The procedure where a doctor uses a camera to screen for cancer in your colon is called a:
Colonoscopy
300
What does the cell cycle have to do with the development of tumors and cancer?
Failed checkpoints in the cell cycle allow cells to grow out-of-control, forming tumors.
300
A woman has a very small tumor on her ovary. The tumor has not spread past the ovary. What stage of cancer does she have?
Stage 1 (it's very small and has not spread at all).
300
What is a "radical mastectomy?"
The removal of the entire breast, and lots of the muscle and lymph nodes surrounding it (a very aggressive treatment for breast cancer).
300
The BRCA genes controls healthy checkpoints in the cell cycle of breast cells. Why, if the BRCA gene mutates, does it lead to breast cancer?
Because the breast cells no longer have working checkpoints! They can grow out of control, and create cancer.
300
The animal which represents cancer is the
Crab.
400
What are the four stages of the cell cycle?
G1, S, G2, M.
400
What role do lymph nodes play in cancer?
Cancer cells use lymph nodes to travel to different parts of the body and create new tumors.
400
Would it be better for someone with stage 4 cancer to get surgery or get chemotherapy?
Chemo -- it can affect the whole body, whereas surgery can really only affect one part.
400
What is "personalized medicine?"
Medicine that is provided based on your DNA. It's tailored to you!
400
How many chromosomes are in a healthy human cell?
46 (23 pairs!)
500
During which stage of the cell cycle is DNA replicated (made fresh for new cells?)
The S phase!
500
A man has a very large tumor in his brain. It has grown and expanded through his brain tissue, and cancerous cells have filled his nearby lymph nodes. The cancer HAS NOT METASTASIZED, however. What stage cancer is it?
Stage 3 (The tumor is large and has become ready to spread by entering the lymph nodes, however it has not yet actually metastasized).
500
What is "hospice care?"
Where a patient goes so that they may die comfortably, around family and friends, without any aggressive treatment.
500
Angelina Jolie chose to have a double mastectomy because she had a mutated BRCA gene. Do you think this was the right decision? Why?
Let's see your answer!

Cancer is the second-highest killer in America. What is the first?
Heart disease.
