The post here gives the information about skin cancer stages and the types.

Skin Cancer Types

The skin cancer types have been categorized based on its origin and effects. These types are melanoma, basal cell skin cancer and squamous cell skin cancer, where the melanoma cancer is the most dangerous skin cancer.

  • Melanoma

    Melanoma is the skin cancer type that develops in melanocytes (the cells that produce brown skin pigments). This is found in the innermost layer of the skin. Melanoma cancer grows very fast and if not treated at its early stage can lead grave consequences. The cancer has no specific location on the skin and can be developed on any part including the places that come very less in contact to the sun light. The cancer is curable if found in the early stage.
  • Basal cell carcinoma

    This type of skin cancer is most common and least dangerous. It develops in the basal cells, which are found in the outermost layer of the skin. The cancer grows slowly and usually found on the head or neck. It can look like a pearly or transparent bump on the skin.
  • Squamous cell carcinoma

    The cancer is not highly dangerous until and unless this is not spread to the other parts of the skin and treated at its early stage. The growth of this cancer is medium and takes months. The cancer usually develops on the part of the skin which is most exposed to the sun.

The basal cells carcinoma and squamous cell carcinoma are together known as non-melanoma cancers.

Skin Cancer Stages

Stage 0

This is the initial stage of skin cancer where cells start turning into cancer; however, they do not start spreading yet.

Stage 4

In the stage 4, the cancer starts growing into the spine, ribs or lower part of the skull. It can also be the case that cancer has grown into a lymph node that is more than 3 cm in size, or has grown to an internal organ, like, lungs.
