1. Skin Cancer: A malignant, primary tumor of the epidermal layer of the skin.

2. Pathophysiology
Unregulated cell growth and uncontrolled cell division result in the development of neoplasm. 
Basal cell keratinization causes basal cells, which also causes tumor growth in the basal layer of the epidermis.
Melanoma occurs when a tumor arises from the melanocytes of the epidermis.
Squamous cell carcinoma occurs when a tumor arises from the keratinocytes of the epidermis.

3. Risk Factors/Causes: Prolonged exposure to UV rays. Hereditary
Chemical irritates
Radiation
Friction or chronic irritation
Immunosuppressive drugs
Precancerous lesions

4. Signs/Symptoms:
Basal cell cancer appears as a waxy nodule with telangiectasia.
Melanoma cancer appears as irregular, circular, broadened lesions with hues of tan, black, or blue.
Squamous cell cancer appears as small, red nodule lesions that begin as an erythematous macule or plaque with indistinct margins.
Pruritus
Local soreness
A change in color, size, or shape of existing lesions.
Oozing, bleeding, or/and crusting lesions.  

5. Lab/Diagnostics Tests:
Skin biopsy

6. Medical Treatments: Cryosurgery with liquid nitrogen Chemosurgery
Radiation therapy
Cryosurgery with liquid nitrogen
Chemosurgery
Antineoplastic
Immunotherapy
Analgesic
Antiemetic
Wound care 

7. Complications: Metastasis Recurrence Curettage and electrodesiccation
Surgical excision
Lymph dissection 

8. Nursing Diagnosis:
Pain
Fear
Disturbed body image

9. Nursing Interventions:
Assess the skin
Assess vital signs and intake/output
Administer medication
Provide post chemotherapy and post radiation therapy.
Instruct the patient on staying out of the sun.
Check the skin regularly for moles as well as for changes in existing moles, freckles, and/or birth marks.
