What Is Skin Cancer?

Skin Cancer: Causes, Symptoms, Diagnosis, and Treatment

Skin is the largest organ of the body and is made up of various cells in constant motion. The skin is made up of three layers, including the epidermis, which is the top layer of the skin. The dermis is the second layer, thicker, while the last one is the subcutaneous layer. The epidermis provides protection to the body and gives color to the skin.

Skin cancer occurs as a result of abnormal growth of cells on the epidermis as a result of unrepaired DNA damage that causes a mutation in cells and results in their continuous growth leading to the formation of malignant tumors and cancer eventually.

1Types Of Skin Cancer

Basal Cell Carcinoma (BCC)

The main types of skin cancer include;

Basal Cell Carcinoma (BCC)

Basal cells are present at the bottom of the epidermis and are one of three primary types of cells in the skin’s top layer. Basal cells shed and cause the formation of new cells. When new cells are produced, they push older cells towards the skin surface, where old cells die and slough off. New cells are produced as instructed by the DNA of basal cells.

DNA contains all the information about the formation of new cells. In case of any mutation, the basal cells start to multiply continually and rapidly; they continue growing when they should normally die. This results in the accumulation of abnormal cells that form cancerous tumors.

Basal cell carcinoma (BCC) is the most common and one of the most frequent cancer forms. In the US, 4 million cases of basal cell carcinoma (BCC) are diagnosed each year. They grow slowly and are curable because they cause minimum damage and easily treated when caught. The risk factors, symptoms, and warning help in the identification of this type of cancer.

BCCs appear like open sores, red patches with pink growths, and shiny bumps. Scars or elevated growths can also be seen as rolled edges or at central indentation.  BCC can also bleed or itch; they may also ooze or form crust.

BCC can spread beyond the original tumor site, and if they continue to grow, the lesions can become disfiguring and dangerous. BCCs become invasive and grow wide and deep into the skin. If not treated early, it can reoccur repeatedly. In some aggressive cases, BCC can become life-threatening.

Basal cell carcinoma (BCC) is highly common; the number of reported cases steadily increased. More than 4 million Americans are diagnosed with BCC each year.
