During a physical examination, a lesion on a client's chest is identified. Which type of skin cancer may this lesion suggest?

The identification of a lesion on a client’s chest during a physical examination can suggest several types of skin cancer, but basal cell carcinoma is a very common type that often appears in such regions. Basal cell carcinoma typically manifests as a small, pearly bump or a flat, scaly patch. It commonly occurs in sun-exposed areas of the skin, such as the chest, and is characterized by its slow growth and low tendency to metastasize compared to other skin cancers.

This type of cancer arises from the basal cells, which are located in the lowest part of the epidermis. Due to factors like ultraviolet (UV) exposure from the sun, basal cell carcinoma is particularly prevalent among individuals with lighter skin. Early detection is key, as treatment is generally very effective when caught early, often requiring surgical excision or other localized therapies.

In contrast, squamous cell carcinoma may present as a firm bump, scaly patch, or ulcerative sore, while malignant melanoma, although more aggressive, has distinguishing features like asymmetry, irregular borders, and varied coloration. Actinic keratosis is not cancer but rather a precancerous condition that appears as rough, scaly patches due to sun exposure, which may potentially develop into squamous cell carcinoma
