True/False Questions

  1. Non-melanoma skin cancers make up about 95% of all skin cancers.
  2. Basal cell carcinoma of the skin is the most common form of human cancer.
  3. Basal cell carcinoma of the skin rarely metastasizes to distant anatomic sites.
  4. Squamous cell carcinoma of the skin is the second most common form of human cancer.
  5. Squamous cell carcinomas of the skin nearly always develop due to malignant transformation of sun-induced precancerous skin lesions known as actinic keratoses.
  6. Squamous cell carcinomas of the skin have little potential to metastasize to other organs.
  7. Merkel cell carcinomas develop from neurosensory cells called Merkel cells that connect with nerve endings to transmit electrical impulses in response to touch.
  8. Arsenic tends to accumulate in the skin and chronic exposure has consistently been found to increase the risk of developing basal cell and squamous cell carcinomas of the skin
  9. Depletion of the ozone layer around the South Pole is related to the high rates of skin cancer in populations living in the southern hemisphere.
  10. Exposure to ultraviolet light in tanning salons is not a risk factor for development of skin cancer because UVB rays are filtered out.
  11. The highest rates of skin cancer are found in populations living near the equator.
  12. Patients who receive psoralen and ultraviolet A radiation (PUVA) for the treatment of skin disorders are at increased risk for the development of skin cancer.

    4. 200%

    2. Population is fair skinned
    3. Emphasis on outdoor activities resulting in high exposure to solar radiation throughout life
    4. High prevalence of xeroderma pigmentosum
    5. a, b, c only are correct.
    6. a, b, c, d are all correct.
