Study Notes
- A private Kahoot quiz called "DOGAN MI Unit 3 Review" contains 20 questions about medical interventions, cancer, and Project Lead The Way (PLTW).
Diagnostic Imaging
- MRI does not expose the patient to ionizing radiation.
Oncogenes
- An oncogene is a gene that is over-expressed in cancer.
Cancerous Cells
- A cell with a large, multi-lobed nucleus can be a characteristic of a cancerous cell.
DNA Microarrays
- DNA microarrays compare the amount of mRNA present in a healthy cell versus an experimental cell.
Cancer Risk Factors
- Smoking is a behavioral risk factor for cancer.
Melanoma
- Melanoma is a potentially lethal form of skin cancer.
Ultraviolet Radiation
- Ultraviolet radiation can cause cancer by causing mutations in the DNA.
BRCA Mutation
- If Becky and Susan both have the BRCA mutation and neither Marie nor Margo have the muation
Viruses and Cancer Risk
- H1N1 influenza is least associated with an increased risk for cancer
Cancer Development
- The majority of cancers are considered to be sporadic.
Mammograms
- A healthy female with no family history should get her first mammogram between 40 and 50 years old.
Chemotherapy Advantages
- Chemotherapy reaches cells throughout the body, but radiation is localized.
Biofeedback
- When using biofeedback, a decrease in heart rate would indicate a positive response
Radioactive Tracers
- A bone scan is a diagnostic imaging technique that uses a radioactive tracer.
Red Meat Consumption
- Eating lots of red meat is a behavioral risk factor for developing cancer.
Skin Cancer and Risk Factors
- Skin cancer is far less common in people of African descent due to biological risk factors.
Radiation therapy
- A small brain tumor would be the best type of cancer to treat with radiation therapy
Chemotherapy and Hair Loss
- Chemotherapy patients often lose their hair because chemo attacks fast-dividing cells, which includes hair cells.
Correlation Coefficient
- A correlation coefficient of -0.90 means the two genes have a strong, opposite behavior.
Pearson Correlation Coefficient
- Using the Pearson Correlation Coefficient, gene 1 and gene 2 have a factor of 0.58 means the genes behave similarly.
