How do skin moles develop

The formation of skin moles starts from skin cells called melanocytes. These cells are responsible for the production of melanin. Melanin is the substance that gives skin and hair its colour.  A skin mole forms when melanocytes pile up or grow abnormally close to each other, rather than being spread evenly on the surface of the skin. There are a few reasons for this to happen. The reasons are listed below:

1) Genetics
2) Hormones secreted by the body ( more common amongst female)
3) Too much exposure to the sun.

Are skin moles dangerous?

All skin moles have potential to become skin cancer. As such, one should be very alert and vigilant in watching the skin moles for traces of melanoma, which grows from melanocytes cells. Sudden change in a mole, whether it is bleeding, rapid growth or irregular size can signify the growth of basal cell, squamous cell or malignamt melanoma.

Changes in a skin mole or multiple mole call for immediate attention by a skin specialist or dermatologist. Thought basal cell is not likely to spread to other parts of the body, moles can grow to exceptional size and may cause scarring after removal.

Squamous cell and melnoma can metastaize at an alarming rate, spreading cancerous cells to other parts of the body. As such, even the smallest skin moles should be watched for rapid changes.
