Exam 3: Cellular Function (Cancer) Flashcards
Incidence and death rates of cancer higher in what population? (2)
Higher in males than females
Higher in black people
Cancer with the highest incidence for women
Cancer with the highest death rate for women
Highest incidence = breast cancer
Highest death rate = lung cancer
Cancer with the highest incidence for men
Cancer with the highest death rate for men
Highest incidence = prostate cancer
Highest death rate = lung cancer
Another term for cancer
“Malignant neoplasms”
Metastasis definition
Cancer cells infiltrate lymph and blood vessels, which carry the mutant cells to other parts of the body.

Tumor shape:
Benign
Malignant
Benign: Regular shape, cells are well-differentiated
Malignant: Irregular shape
Tumor spread to adjacent tissues:
Benign
Malignant
Benign: Non-invasive: Does not invade surrounding tissue
Malignant: Invasive: Invades surrounding tissue.
Tumor metastasis:
Benign
Malignant
Benign: Localized
Malignant: Metastasizes to distant sites
Tumor encapsulation:
Benign
Malignant
Benign: Encapsulated (usually by fibrous capsule)
Malignant: Not encapsulated
Tumor potential for growth:
Benign
Malignant
Benign: Decreased potential for growth
Malignant: Increased potential for growth
Tumor recurrence after surgical excision:
Benign
Malignant
Benign: Decreased recurrence
Malignant: Increased recurrence
Tumor as the cause of death:
Benign
Malignant
Benign: Doesn’t usually cause death unless location interferes with vital function
Malignant: Usually causes death unless growth can be controlled
Three mechanisms of cancer spread:
1) Metastasis
2) Invasion
3) Seed
4 Risk categories for cancer
1) Environmental
2) Genetic / familial
3) Hormonal agents
4) Age

are associated with ONE chemical in cigarettes!
Two genes that increase the risk of ovarian cancer
Broncho1
Broncho2
What family history should you take when looking at cancer
Immediate relatives (parents, siblings)
Three factors that correlate with a higher incidence of breast cancer
- Early onset menses
- Late menopause
- Have never given birth
Recommended fruit and vegetable intake
5-9 per day
Standard guidelines to detect/screen BREAST CANCER (2)
- Mammogram q 2 years
- Clinical breast exam:
q 4 years 20-39
q 1 year age 40+

If 50 years or older:
Yearly fecal occult blood test and one of the following:
- Sigmoidoscopy every 5 years OR
- Colonoscopy every 10 years

- Unexplained fever
- Fatigue
- Pain
- Skin clues
Seven common cancer symptoms (American Cancer Society)
1) Change in bowel / bladder function
2) Sores that do not heal
3) Unusual bleeding or discharge
4) Thickening, lump
5) Indigestion or difficulty swallowing
6) Recent change or difficulty swallowing
7) Nagging cough or hoarseness
