are all basal cells cancerous?

Basal cell carcinoma is a type of skin cancer. Basal cell carcinoma begins in the basal cells — a type of cell within the skin that produces new skin cells as old ones die off. Basal cell carcinoma often appears as a slightly transparent bump on the skin, though it can take other forms.

Skin cancer — the abnormal growth of skin cells — most often develops on skin exposed to the sun. But this common form of cancer can also occur on areas of your skin not ordinarily exposed to sunlight. There are three major types of skin cancer — basal cell carcinoma, squamous cell carcinoma and melanoma.

Tattoos definitively do not cause skin cancer. According to the Skin Cancer Foundation, dermatologists have been investigating the link between tattoos and skin cancer for decades, and there is no evidence that tattoos in any way raise the risk of skin cancer.

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.

Although the nonmelanoma skin cancer basal cell carcinoma (BCC) is rarely life-threatening, it can be troublesome, especially because 80 percent of BCCs develop on highly visible areas of the head and neck.

There are three main types of skin cancer . The most serious is melanoma. Like all body tissues our skin is made up of cells: basal cells, squamous cells and melanocytes. The different types of skin cancer are named for the skin cell where the cancer develops: basal cell carcinoma, squamous cell carcinoma and melanoma.

This is one of several proposed explanations for the rising incidence of skin cancer. Fortunately, zinc oxide blocks virtually the entire UVA and UVB spectrum. This makes it the most complete block known.

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.

It's very rare for a basal cell cancer to spread to other parts of the body. But if it's left untreated, basal cell cancer can grow into nearby areas and invade the bone or other tissues beneath the skin.

Though this form of skin cancer is not usually life-threatening, one major difference between basal cell and squamous cell cancers is that squamous cell cancer are more likely to grow deeper into the layers of your skin and spread to other parts of the body.

Most basal cell and squamous cell cancers can be cured with surgery or other types of treatments that affect only the spot on the skin. The treatment plan that's best for you will depend on: The stage and grade of the cancer. The chance that a type of treatment will cure the cancer or help in some way.

Squamous cell carcinomas may also develop as a lump on the skin. These firm lumps are typically rough on the surface, unlike the smooth and pearly appearance of a basal cell carcinoma. If a nodule doesn't form, the cancer may develop more like a reddish, scaly patch.

Some actinic keratoses can turn into squamous cell skin cancer. Because of this, the lesions are often called precancer. They are not life-threatening. But if they are found and treated early, they do not have the chance to develop into skin cancer.

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.

Sunburn accelerates skin aging and is a leading cause in the majority of cases of basal cell carcinoma, squamous cell carcinoma and melanoma, the deadliest form of skin cancer. Sunburn is bad news, but the good news is that it's totally preventable.

Squamous cell carcinoma of the skin is a common form of skin cancer that develops in the squamous cells that make up the middle and outer layers of the skin. Squamous cell carcinoma of the skin is usually not life-threatening, though it can be aggressive.

Inheritance and Risk Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are two of the most common malignancies in the United States and are often caused by sun exposure, although several hereditary syndromes and genes are also associated with an increased risk of developing these cancers.
