Skin Cancer:

external signs of skin cancer is divided into four types:

  • Basal cell carcinoma( CCL) is the most common form and is 90% of all skin cancers. It begins in the basal cells, in the lower part of the epidermis( the outer layer of the skin), which is caused by prolonged exposure to direct sunlight. This is easily treated.
  • Squamous cell carcinoma( RCC) is the second most common type. It begins in the epidermis, eventually spreads over the entire skin, if not treated. It is easily treated if the cancer is detected at an early stage, but in a small percentage of cases, the cancer has spread( metastasized) to other parts of the body.
  • Malignant melanoma( 3M) is the most severe type of skin cancer and is responsible for most deaths. However, it can be cured if it is diagnosed and removed at an early stage.
