1. Try to put yourself into Miranda’s situation. What does she need to know to “wrap her head
around this”? What questions would she need to ask?
Miranda should know what type of treatments there are for the certain type of cancer her
mother has. She should ask how effective these treatments have been on other patients and
what the side effects could possibly be.
2. What resources could she consult to help her address these questions?
The American Association for Cancer Research, The National Cancer Institute, The
Centers for Disease Control and Prevention, she could also ask her mom or her mom’s doctor.
1. What is cancer and how does it relate to the cell cycle?
Cancer is a disease in which abnormal cells divide uncontrollably and destroy body
tissue. It relates to the cell cycle because in the cell cycle, cells divide and eventually die.
Cancer cells divide at a very fast rate and the cells are also considered to be immortal.
2. What are proto-oncogenes and tumor suppressor genes, and how do they contribute to
cancer?
Proto oncogenes are genes that stimulate cell division and death,and it contributes to
cancer as when it malfunctions it's directly responsible for causing cancer due to cell division
being completely random and unregulated, also cells cease to die. A tumor suppressor gene is a
gene that deters cells from becoming cancerous and causing tumors or cancer. This helps in
causing cancer as when its mutated, all the cells it protected from becoming cancerous no
longer have a safeguard,and this soon leads to cancer as nothing protects cells from becoming
cancerous.
3. What are some things that might make a person have a higher risk of developing cancer?
Some factors that let a person to have a higher risk of cancer could be exposure to
radioactive chemicals. Some other ways is that it's hereditary, passed down from parents to
offspring. If someone in your family has cancer it could have possibly been passed down to you.
Specifically, if you have the BRCA 1 or BRCA 2 genes.
4. What are some of the major steps that occur in the progression from a single cancer cell to a
tumor and then to many tumors spreading throughout the body?
As cells become abnormal, they gain the ability to release growth stimulators and
digestive enzymes. The cells divide rapidly and impact other nearby cells, which reduces the
ability of the affected organ to function properly.
5. As tumors grow and spread, the cells undergo a number of changes. How might the cells in a
late stage tumor be different from the original cell that became cancerous?
The main difference between cancerous cells and regular cells is that cancerous cells
are a damaged and mutated form of normal cells. The identity of the mutation is the corrupted
ability for cells to divide. Cells divide but in a regulated manner so a tumor may not initiate.
