The most common type of skin cancer, Basal cell carcinoma (BCC) makes up about 75% of all non-melanoma skin cancers. As a cancer of the epidermis (the outermost layer of the skin), the disease usually presents as a non-healing pink or translucent nodule or lesion that may or may not itch.
BCC tumours tends to grow slowly, but when left untreated, can invade other tissues beneath the skin and can spread to other parts of the body—a process known as metastasizing. BCCs are usually diagnosed by their appearance, or by examination using a dermatoscope. It is important to keep in mind that it is possible to have more than one BCC at a time, and in fact, having one can increase your risk of getting another.
BASAL CELL CARCINOMA OVERVIEW
What is BCC?
BCC is a non-melanoma skin cancer that affects the epidermis—the outermost layer of the skin. It typically appears on patches of skin most likely to have been exposed to the sun, or artificial light sources like tanning beds.
BCC can present in one of many distinct clinical types. These range from less aggressive forms like Nodular BCC, to the more aggressive Morpheaform BCC. Only a proper diagnosis can confirm which type a patient may have.
BCCs can appear in one of over 20 historical growth patterns ranging from a shiny, pearl like node, to a waxy, scar-like plaque with indistinct borders.
Advanced BCC encompasses a heterogeneous assortment of cases, including metastatic BCC as well as locally advanced BCC (for which no formal definition exists but which generally includes large, deep, aggressive, or recurrent tumors).
While your own personal history, genetics and age may play a factor in a BCC diagnosis, it is important to note that like most cancers, the disease can affect people of all ages and races.
BCC usually presents as a non-healing pink or translucent nodule/lesion which may sometimes cause itching. It typically appears on a sun-exposed area of skin, such as the face and neck. The best way to identify a potential skin cancer issue right away is by performing regular skin self-checks. Learn about the most common characteristics of BCC.
85% of skin cancers are caused by UV radiation. Overexposure to the sun and other sources of ultraviolet radiation are known to cause harm to the skin, eyes and immune system. The number one preventable risk factor for the most common forms of melanoma and skin cancers is overexposure to damaging UVR.
