Focus on Skin Cancer: An Overview


The start of summer in Australia is an important time for nurses to turn their focus to the skin. Australia has one of the highest skin cancer rates worldwide; with current predictions forecasting at least two out of three Australians will be diagnosed with skin cancer by the age of 70. Luckily, skin cancer is visible, mostly preventable and curable when detected and treated early.

Though the rates of skin cancer diagnoses are forecast to increase, the stable figures for individuals under the age of 45 currently reflect Australia’s long-standing public education on UV (ultra violet) avoidance and protection.

Nurses should expect to care for individuals with sun-damaged skin who have an increased risk of developing skin cancer, possibly “incidental” to their primary reason for care. In addition to the physical concerns, the psychosocial ramifications of skin cancer following diagnosis are well documented. Anxiety and depression may stem from the fear of actual or anticipated disfigurement, multiple surgeries and treatments. Financial costs, disrupted social relationships and impaired lifestyle add to the burden.

Effective nurse participation in skin cancer recognition, prevention and management, as well as patient support and guidance along recognised referral pathways, requires a basic knowledge and understanding of melanoma and non-melanoma skin cancer.

Types of Skin Cancer

The three main types of skin cancer originate from epidermal cell genetic mutation:

Basal Cell Carcinoma

BCCBasal Cell Carcinomas (BCC) derive from stem cells located in the epidermal basal layer or hair follicles.

Squamous Cell Carcinoma

Squamous Cell Carcinomas Squamous Cell Carcinomas (SCC) develops from keratinocytes.

Melanoma

MelanomaMelanoma advances from melanocytes, basal layer pigment producing cells.

BCCs may display a classic rolled edge or small visible blood vessels; alternatively there may be a pink smudge or a pale, firm, scar-like lesion. SCCs, on the other hand, may exhibit a heaped-up border, ulceration or have a keratotic “horn”.

Melanoma may present as a new or changing lesion, usually pigmented, with colour variation and its appearance may differ from other pigmented lesions on the person. BCCs, SCCs and melanomas can present in sub-types. Though each skin cancer has classic characteristics, they may vary from the description usually attributed to it. Specific tumour behaviour, treatment choice and outcome potential also alter with the specific type.

Subtleties in appearance may impact accuracy and timeliness of diagnosis, care flow, health resources and patient morbidity and mortality.

For instance, the ABCDE rule applies for identifying some suspicious pigmented lesions:

  • Asymmetry
  • Border irregularity
  • Colour variegation
  • Diameter > 6 mm
  • Evolution or enlarging

However, you must be aware that in paediatrics, nodular or amelanotic melanoma the individual might not present with conventional ABCDE criteria for diagnosing a suspicious lesion or melanoma.

Risk Factors

bodyimage

A history of indoor tanning can increase the risk of developing skin cancer.

There are a number of risk factors around skin cancer that should also be taken into account.

  • Light skin colour, blue or green eyes, blonde or red hair
  • Family or personal history of skin cancer
  • Sun exposure (main risk) through work and recreation
  • A history of sunburns, especially in childhood
  • A history of indoor tanning
  • Certain types and a large number of moles
  • Immune compromise through disease, age or medication compounds other risks

Nurses are well positioned to have a positive impact on community skin cancer awareness and to advise on sun protection and minimisation techniques. Wherever you work as a nurse, you have a role in education, prevention and management around skin cancers.

Greater nurse knowledge and awareness increases vigilance, aids early identification and improves patient outcomes. Irrespective of care context, it is best to approach suspicious or new lesions and non-healing wounds with a level of wariness.
