Final answer:
Neoplasms that arise from epithelial tissue and commonly occur on sun-exposed areas of the body are typically skin cancers, such as basal cell carcinoma and melanoma. They are most often found on the head, neck, arms, and back due to heavy sun exposure, however, there can be other causes as well.
Step-by-step explanation:
The neoplasms that arise from epithelial tissue and most commonly occur on sun-exposed areas of the body are typically skin cancers, such as basal cell carcinoma and melanoma. These types of cancers originate from cells in the stratum basale of the epidermis and melanocytes, respectively. They are most prevalent on the head, neck, arms, and back, which are heavily exposed to UV radiation from the sun. Other factors, such as radiation exposure and certain chemicals like arsenic, can also lead to these cancers. Wounds on the skin due to things like open sores, tattoos, and burns can also serve as predisposing factors. Both basal cell carcinoma and melanoma can eventually produce an uneven patch, bump, growth, or scar on skin surface and require immediate treatment through surgical removal or topical ointments, as early intervention offers the best chance for successful treatment.
