Question | Answer |
---|---|
True or False?Malignant transformation occurs with aneuploidy? | True |
True or False?When a cell gains or loses whole chromosomes it does not have structural abnormalities? | False. It does have structural abnormalities. (page 476 iggy) |
True or False?When grading a tumor Gx cannot be determined? | True |
True or False?Tumor cells that are well differentiated and closely resemble the normal cells are graded as G1? | True |
True or False? G4 tumor cells resemble the normal cells from which they arose? | False. G4 tumor cells are poorly differentiated and retain no normal cell characteristics. Determination of the tissue orgin is difficult and impossible. (Page 476 iggy) |
TNM system stands for? | Tumor, node, metastasis system |
TNM systems have specific prognostic value for this type of tumor? | Solid type tumors |
True of False?TNM staging is useful for leukemia and lymphomas? | False. (Page 476 Iggy) |
Name the 3 ways staging is done for cancer? | 1. clinical staging 2.Surgical staging 3.Pathologic staging |
True or False?TNM system refers to:Tumor, lymph nodes, extent of local, regional, and distant metastasis? | True |
True or False?When staging a tumor, the letter "M" stands for Primary Tumor? | False. The letter "T" stands for Primary tumor.The letter "N" stands for NODE. The letter "M" stands for METASTASIS. |
This staging assess the client's manifestations, signs for tumor size and possible spread? (What is this staging called) | Clinical staging |
Tests are used and cancer cells may be obtained for biopsy in this stage, but this stage does not include MAJOR SURGERY. What is this STAGE called? | Clinical staging |
This staging assesses the tumor size, number, sites and spread by INSPECTION at SURGERY. What is this staging called? | Surgical staging |
This is the most definitive type of staging. What is it called? | Pathologic staging |
True or False?The American joint Committee on Cancer developed the TNM system to describe the anatomic extent of cancers? | True |
What 3 factors play a role in carcinogenesis? | 1. Exposure to carcinogens 2. Genetic predispositon 3. Immune function |
The activation of proto-oncogenes into oncogenes causes? | Carcinogenesis |
Proto-oncogenes are genes that direct what? | Early embryonic development |
At what day do the suppressor genes turn off the control of the proto-oncogenes to keep them from being overexpressed? | On day 8. Suppressor genes can act directly at the DNA level, preventing the proto-oncogene from being overexpressed. |
When a normal cell is exposed to any carcinogen, what specific cell's DNA can be damaged or mutated? | Suppressor gene |
True or False?There are about 70 different proto-oncogenes that can be activated into oncogenes and are not considered abnormal genes but are part of every cell's normal makeup and were important in early development? | True |
True or False?Oncogenes can cause the cell to change from normal to cancer cells and uncontrolled cell division? | True |
True or False?When thinking about carcinogenesis, many household chemicals, drugs and other products used in everyday life should be considered? | True |
True or False?Small doses of radiation do not affect cells? | False (Page 477iggy) |
True or False?Lung, Pharyngeal, Esophagus, Cervical, Bladder, Stomach, Oral cavity, Laryngeal, Pancreatic, Kidney, Liver and Myeloid Leukemia can all be caused from Tobacco Use? | True |
How long do platelets live? | 7 to 10 days |
What two types of Radiation rays cause cancer? | Ionizing and UV rays |
The incidence in skin cancer is higher in people with what type of injuries? | burn scars and severe skin injuries |
Barrett's Esophagus is considered to be an example of what type of cancer? | Chronic irritation cancer due to tissue trauma. |
This type of viral origin is known to cause Burkitt's lymphoma, B-cell lymphoma, and nasophryngeal carcinoma? | Epstein-Barr Virus |
This type of viral origin is known to cause primary liver carcinoma? | Hepatitis B virus |
What 3 personal factors affect cancer development? | Age, immune function, Genetic Risk |
What are 7 Risk factors for developing cancer? | 1. Tobacco 2. Alcohol 3. Occupational Exposure 4. Radiation 5. Diet 6. Viruses 7. Drugs |
Oncoviruses | Viruses that cause cancer (hepatitis B; Epstein-Barr) |
What test can confirm or rule out a person's predisposition or risk for specific cancers? | Genetic Testing |
