- Ultraviolet (UV) rays from the sun or from a tanning bed are the main cause of basal cell carcinoma. When UV rays hit your skin, over time, they can damage the DNA in your skin cells. The DNA holds the code for the way these cells grow. Over time, damage to the DNA can cause cancer to form.

Overview 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. You can reduce your risk of skin cancer by limiting or avoiding exposure to ultraviolet (UV) radiation. Checking your skin for suspicious changes can help detect skin cancer at its earliest stages. Early detection of skin cancer gives you the greatest chance for successful skin cancer treatment.

Cancer cell Carcinogenesis is caused by mutation and epimutation of the genetic material of normal cells, which upsets the normal balance between proliferation and cell death. This results in uncontrolled cell division and the evolution of those cells by natural selection in the body.

What Causes Basal and Squamous Cell Skin Cancers? Genes that keep cell growth in check by slowing down cell division or causing cells to die at the right time are called tumor suppressor genes. Cancers can be caused by DNA changes that turn on oncogenes or turn off tumor suppressor genes.esearchers don’t yet know all of the DNA changes that result in skin cancer, but they have found that in many skin cancers the cells have changes in tumor suppressor genes. The gene most often altered in squamous cell cancers is called TP53. This tumor suppressor gene normally causes cells with damaged DNA to die.

Skin cancer Basal-cell carcinoma or basalioma is the most common type of skin cancer and it develops from the basal cells inside the subcutaneous tissue. It is the most commonly diagnosed type of cancer in the world, and it surpasses lung cancer, breast cancer, colorectal cancer and prostate cancer in the number of discovered cases.

Skin Cancer FAQs Basal cell carcinoma is the most common type of skin cancer. It usually appears on sun-exposed areas as a blemish that won't heal or a persistent, pearly, shiny bump. The area may bleed with minor trauma. There are several other presentations including one that appears like a red, rough patch.quamous cell carcinoma can occasionally spread into the lymph nodes and internal organs. This occurs more often with large, aggressive squamous cell carcinomas or rapidly-growing tumors on the ears, scalp, lips or genitalia.

- Introduction. Basal cell carcinoma is the most common type of skin cancer. It occurs when the basal cells in the skin grow abnormally and out of control. Exposure from ultraviolet (UV) radiation from the sun is the most frequent cause of basal cell carcinoma.asal cell carcinoma is a slow growing skin tumor. It usually does not spread to distant parts of the body or into the blood stream. Basal cell carcinoma does spread on the skin and can become quite large over time. If left untreated, it can spread to the muscles, nerves, bones, brain, and in rare cases, cause death.

- Basal cell carcinoma (BCC) is the most common skin cancer in humans, yet it accounts for less than 0.1% of patient deaths due to cancer. Basal cell skin cancer tumors typically appear on sun-exposed skin, are slow growing, and rarely metastasize (0.028-0.55%).

Overview What is Basal Cell Carcinoma? 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 waxy bump, though it can take other forms.

What Is Basal Cell Carcinoma? Basal cell carcinoma is the most common form of non-melanoma skin cancer that forms in the basal cells of the skin as an abnormal growth of lesions.he skin cancer of basal skin cells is usually confused with benign skin tags or moles due to their similarity in appearance with moles. Some basal cell carcinoma symptoms appear as flat red patches or maybe a pearl-like or bumped mole-like rim that surrounds a crater.
