Cancer Incidences Relating to Skin: Occurrence Rates and Beyond
In contrast to basal and squamous cell carcinomas, less common skin cancers such as dermatofibrosarcoma protuberans (DFSP), Merkel cell carcinoma (MCC), cutaneous T-cell lymphoma (CTCL), and Kaposi sarcoma (KS) are far rarer. Each of these cancers presents unique characteristics in terms of prevalence, symptoms, and risk factors.
Dermatofibrosarcoma protuberans (DFSP) is a slow-growing tumor of the dermis, often appearing as firm, protuberant nodules or plaques, usually skin-colored or reddish. Although its exact incidence isn't commonly reported, it's generally recognised that DFSP occurs less frequently. Prior skin trauma or scars may contribute to the risk, although specific details were not provided in our research.
Merkel Cell Carcinoma (MCC) is an extremely rare neuroendocrine tumor, with around 0.23 cases per 100,000 people diagnosed annually. Incidence is on the rise, particularly among older adults, Caucasians, immunosuppressed individuals, and those with significant UV exposure history. Approximately 80% of MCC cases are linked to Merkel cell polyomavirus infection, highlighting a viral oncogenesis component.
Cutaneous T-cell lymphoma (CTCL) is a lymphoma primarily involving skin T-cells, often presenting with eczema-like or plaque lesions. It's a rare cancer, and while prevalence and detailed risk factor data were not provided in our research, it's known to be indolent, with some immune-related risk implications.
Kaposi Sarcoma (KS) is a cancer caused by Kaposi’s sarcoma-associated herpesvirus (KSHV). It's characterised by dark skin lesions, often found on legs, face or genitalia. KS is strongly linked with immunosuppression, particularly in HIV/AIDS patients, leading to dramatically increased risk.
It's important to note that while these less common skin cancers are rarer, skin cancer remains a significant health concern. In the United States, the American Cancer Society states that around 15,000 deaths are caused by skin cancer each year, a figure that has been steadily decreasing. Smoking increases the risk of developing squamous cell carcinoma, particularly on the lips. Protecting yourself from UV rays during the sun's peak hours by staying inside or keeping in the shade can help reduce your risk.
The American Academy of Dermatology reports that doctors diagnose approximately 9,500 cases of skin cancer in the United States every day. People with lighter skin, red or blonde hair, and light eyes are more likely to get skin cancer. After 50 years, the risk of melanoma increases for males. UV light exposure from the sun, tanning beds, and sun lamps increases the risk of melanoma. Most of these cases are nonmelanoma skin cancers (NMSCs).
In the United States, around 5.4 million cases of NMSCs are diagnosed every year. Wearing sunscreen, hats, and long sleeves can help prevent UV ray exposure and reduce the risk of skin cancer. Females under 50 years old have a higher risk of melanoma compared to males in the same age group. BCC and SCC are more common in males and older adults. Melanoma accounts for around 5% of skin cancers but causes most skin cancer-related deaths.
Merkel cell carcinoma is an uncommon type of skin cancer, with around 2,000 cases diagnosed in the U.S. each year. Using tanning beds and sunlamps can increase the risk of melanoma. BCC is more common, accounting for around 8 out of 10 NMSCs.
