Types of Skin cancer

Mostly, three types of skin cancer are reported throughout the world. These are:
  • Basal cell carcinoma
  • Squamous cell carcinoma and
  • Malignant melanoma
Other less common types are:
  • Merkel cell carcinoma
  • Dermatofibrosarcoma
  • Kaposi’s sarcoma
  • Spindle cell tumors
  • Keratocanthoma
  • Sebaceous carcinomas
  • Angiosarcoma
  • Atypical fibroxanthoma
  • Microcystic adnexal carcinoma
  • Leimyosarcoma
  • Pagets’s disease of the breast
All of these have their own distinct symptoms, appearance and treatment. The type is determined by the kind of skin cells from these caners arise. There are certain skin cancers that occur in a specific body area. A brief description of all types is given below.

Basal cell carcinoma
This is the most common form of skin cancer and affects over 90 percent of skin cancer patients in U.S. It is not as malignant as other types are and is the least dangerous of all three cancers. In this condition, growth is slower and it spreads rarely that is: in 1 patient out of 1,000.


Squamous cell carcinoma
This cancer spreads to vital body organs, so it is more serious and severe in nature than basal cell carcinoma. It also spreads slow three to five in every hundred patients. Initially, cancer cells spread up to the lymph node structures that trap and filter out these cells. By removing the affected lymph node the patient can get rid of this fatal disease prior to its spread to body organs. If it is late and the organs are also affected by cancer cells, it is serious and needs special therapy to recover from this horrible condition.

Malignant Melanoma
As the word “malignant” suggest, it is the most serious kind among all skin cancers diagnosed so far. It spreads fast through the lymph nodes or the blood to internal body organs. Melanoma starts in pigment-producing cells known as melanocytes, that are mainly present in the lower part of the outer skin layer, epidermis.
