are basal cells always cancerous?

The bottom layer of the epidermis is the basal cell layer. With basal cancer, cells in this layer are the ones that become cancerous. Most basal cell cancers occur on skin that is regularly exposed to sunlight or other ultraviolet radiation. This type of skin cancer is most common in people over age 50.

The Most Common Skin Cancer Basal cell carcinoma (BCC) is the most common form of skin cancer and the most frequently occurring form of all cancers. In the U.S. alone, more than 4 million cases are diagnosed each year. BCCs arise from abnormal, uncontrolled growth of basal cells.

The Most Common Skin Cancer In the U.S. alone, more than 4 million cases are diagnosed each year. BCCs arise from abnormal, uncontrolled growth of basal cells. Because BCCs grow slowly, most are curable and cause minimal damage when caught and treated early.

Basal cell carcinomas (BCCs) and also commonly known as rodent ulcers because they gradually gnaw away in the skin (like a rodent). They are a type of skin cancer but because they grow slowly and do not (usually) spread to other parts of the body.

Basal cell carcinoma appears as a change in the skin, such as a growth or a sore that won't heal. These changes in the skin (lesions) usually have one of the following characteristics: A pearly white, skin-colored or pink bump that is translucent, meaning you can see a bit through the surface.

It's a popular myth that hairy moles are often cancerous, but that's all it is: a myth. In fact, the presence of a hair growing out of a mole may indicate that the spot is actually healthy and noncancerous.

The skin features that frequently develop are listed below. For basal cell carcinoma, 2 or more of the following features may be present: An open sore that bleeds, oozes, or crusts and remains open for several weeks. A reddish, raised patch or irritated area that may crust or itch, but rarely hurts.

Melanoma. These cancers develop from melanocytes, the pigment-making cells found in the epidermis. Melanomas are much less common than basal and squamous cell cancers, but they are more likely to grow and spread if left untreated. Melanoma are discussed in Melanoma Skin Cancer.

There are three major types of skin cancers: basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma. The first two skin cancers are grouped together as non-melanoma skin cancers. Other unusual types of skin cancer include Merkel cell tumors and dermatofibrosarcoma protruberans.

The histologic features of both neoplasms were typical of acinic cell carcinoma. While this may represent a coincidental event, the possibility that this familial occurrence is a manifestation of common genetic or environmental risk cannot be excluded.

Basal cell carcinoma (BCC) is caused by damage and subsequent DNA changes to the basal cells in the outermost layer of skin. Exposure to ultraviolet (UV) radiation from the sun and indoor tanning is the major cause of BCCs and most skin cancers.

Several skin lesions are very common and almost always benign (non-cancerous). These conditions include moles, freckles, skin tags, benign lentigines, and seborrheic keratoses. However, moles are the most commonly examined for cancer if changes are detected.

If left untreated, basal cell carcinomas can become quite large, cause disfigurement, and in rare cases, spread to other parts of the body and cause death. Your skin covers your body and protects it from the environment.

Almost all moles are benign (noncancerous). But new moles in an adult are more likely to become cancerous than old moles. If a new mole appears when you're older, or if a mole changes in appearance, you should see a dermatologist to make sure it's not cancerous.

History of skin cancer including basal cell carcinoma (BCC). Age over 50: Most SCCs appear in people over age 50. Fair skin: People with fair skin are at an increased risk for SCC. Gender: Men are more likely to develop SCC.

The basal layer is the innermost layer of the epidermis, and contains small round cells called basal cells. The basal cells continually divide, and new cells constantly push older ones up toward the surface of the skin, where they are eventually shed.
