What You Should Know About Skin Cancer

Skin cancer is the uncontrolled growth of abnormal skin cells. If left unchecked, these cancer cells can spread from the skin into other tissues and organs. Exposure to ultraviolet (UV) radiation from the sun is the primary cause of skin cancer. Skin cancer may also be due to genetics (heredity), or radiation treatments. Especially for Kaposi Sarcoma (one of non-melanoma skin cancer) is caused by virus. There are two kind of skin cancer, melanoma skin cancer and non-melanoma skin cancer.


1. Melanoma Skin Cancer
Melanoma is a cancer that begins in the melanocytes. It also known as malignant melanoma or cutaneous melanoma. Most of melanoma cells still produces melamin so that’s why melanoma tumors are usually brown or black. But sometimes, melanomas can be non-pigmented and appear pink, tan, or even white. Melanoma skin cancer can also form in other parts of your body such as eyes, mouth, and vagina. Melanoma is much less common than other skin cancer, but it’s more dangerous than others.

2. Non-melanoma Skin Cancer
It called non-melanoma because they develop skin cancer cells in other than melanocytes. They tend to behave very differently from melanomas and are often treated in different ways. Non melanona skin cancers include basal cell and squamous cell cancer are rarely spread or metastasize to other parts of the body, makes them less worrisome than melanoma skin cancer.
People at risk for developing skin cancer may have the following conditions or characteristics:

  • Fair skin
  • Spend a lot of time outdoors in work or leisure activities
  • History of sunburn
  • Family history of skin cancer
  • Many moles
  • People over age 40
  • Large dark-colored birthmark known as congenital melanocytic nevus
  • Pre-cancerous skin lesions, such as actinic keratosis
  • HIV / Human Immunodeficiency Virus (a risk for Kaposi’s sarcoma specifically)
