Most Common Type of Skin Cancer | BCC, SCC and Melanoma | All ...

If you ask about the most common type of skin cancer, There are several different kinds of skin cancers, distinguished by the types of cells affected. Skin cancers are divided into:

• Melanoma (?malignant melanoma?). This type of skin cancer develops from melanocytes.
• Non-melanoma. These are divided into:

-????????? Basal cell carcinoma (BCC) ? skin cancer which develops from basal cells. This is also sometimes called a rodent ulcer.

-????????? Squamous cell carcinoma (SCC) ? skin cancer which develops from keratinocytes.

-????????? Other ? other types of skin cancer, which are rare.

1. BASAL CELL CARCINOMA (BCC)

basal cell carcinoma

It is the most common and curable type of skin cancer as well as the one that spreads the least. It?s developing in more than one million people each year in the United States. It appears a pearly looking bump on the face, ears, or neck area. In some cases, it causes a flat lesion that looks like a scar on the chest or back area. Its characteristics are shiny translucent or pearly nodule, a sore that does not heal, a pink slightly elevated growth, reddish irritated patches of skin, or a waxy scar. While these tumors very rarely spread to other parts of the body, early diagnosis and treatment is necessary to prevent extensive damage to surrounding tissue.

2. SQUAMOUS CELL CARCINOMA (SCC)

Squamous cell carcinoma

It is the second most common skin cancer, affects the squamous skin cells, which are present in the upper layers of the skin. It is less common that BCC, with about 200,000 cases reported each year in the United States. It begins when the squamous cells of the epidermis start to grow in a rapid and uncontrollable way which ultimately leads to the development of a cancerous tumour. Squamous cell carcinoma may appear as a crusted or scaly area of skin with a red inflamed base that resembles a growing tumor, non-healing ulcer or crusted-over patch of skin. While it usually appears on areas of the body that are exposed to the sun, it can develop anywhere, including the inside of the mouth and the genitalia. The causes of SCC include those that cause BCC, as well as frequent tanning bed use, a weakened immune system and genetic predisposition. SCC requires early treatment to prevent it from spreading to other areas of the body.

3. MELANOMA

Melanoma

It is commonly called the malignant melanoma, is the most dangerous type of skin cancer, and it causes the most deaths. It can show up on any part of the body and often appears on either normal skin or in a mole that develops into a malignancy. It is most commonly seen on the trunk, head and neck region in men. Melanoma occurs within the melanocytes, the pigment-producing cells of the skin. Factors involved in the risk assessment of developing melanoma include exposure to the sun, skin type, the extent to which moles are present and family history. This tumor has a large, brown mole like appearance and can appear on your arms, back, leg or face. Although it resembles a mole there are subtle differences, Malignant melanomas are often a different color to normal moles and they are often larger and more uneven.
