Approximately 1% to 10% of all basal cell carcinomas progress to an advanced stage. Not seeking care for concerning skin lesions is a big factor in the development of advanced stage skin cancer.
Basal cell carcinoma (BCC) is a type of skin cancer. Along with squamous cell carcinoma (SCC), it’s the most common of all cancer types.
The American Cancer Society (ACS) estimates that 5.4 million basal or squamous cell carcinomas are diagnosed in the United States each year. Of these, about 80% are BCC.
Many times, BCC remains localized to a single area. However, in rarer cases, it can spread deeper into surrounding tissues or to more distant tissues. This is called advanced BCC.
BCC is advanced when it has spread deeper into surrounding tissues or to more distant parts of the body. It’s estimated that 1% to 10 % of BCCs progress to an advanced stage.
When advanced BCC has spread from the original lesion site and deeper into surrounding skin and tissues, it’s called locally advanced BCC. While this cancer remains at the original site, the extent of its spread makes it challenging to treat.
If advanced BCC has spread from the original lesion site to more distant tissues, it’s called metastatic BCC. This type of advanced BCC is very rare, accounting for less than 1% of all BCCs.
The most common metastatic site for BCC is the lymph nodes. However, it may also spread to the bones, lungs, and liver.
Advanced BCC arises from an earlier cancerous lesion that wasn’t treated or has recurred after treatment. This type of cancer most commonly appears on areas that are frequently exposed to sunlight, such as the:
•face
•scalp
•ears
•neck
•shoulders or upper back
BCC is caused by DNA changes in basal skin cells that promote uncontrolled cell growth and division. Many BCCs are caused by changes affecting the hedgehog signaling pathway.
This pathway is involved in regulating cell growth and division. When it isn’t functioning as it should, the basal cells begin to grow and divide out of control.
The main driver of changes that lead to BCC is exposure to ultraviolet (UV) radiation, which is found in sunlight and in tanning beds. Other risk factors for BCC include:
•older age
•having light-colored skin
•being assigned male at birth
In order to diagnose advanced BCC, a dermatologist will first take your medical history. They’ll ask you about topics like:
•when you first noticed the lesion
•if the lesion has changed in size or appearance since it first appeared
•any other symptoms associated with the lesion, such as itching, pain, or bleeding
•whether or not you’re having any other symptoms
•whether you have a personal or family history of skin cancer
Surgery and radiation therapy are two common treatments for BCC. In some situations, these may also be used for some types of advanced BCC.
However, many people with advanced BCC can’t be treated with these methods due to the size of the cancer, its location, or how far it has spread.
This means that a systemic treatment is needed. A systemic treatment is one that works throughout the whole body.
The Food and Drug Administration (FDA) has approved three systemic treatments for advanced BCC rather recently. Let’s explore these now.
Generally speaking, the outlook for people with advanced BCC is poorer than that for people with an earlier stage of BCC. This is because the cancer has spread further and, as such, can be more challenging to treat.
According to the ACS, the number of people who die due to BCC and SCC is unknown because these cancers aren’t tracked by cancer registries. It’s thought that 2,000 people in the United States die from BCC and SCC each year.
Several factors can affect the outlook for people with advanced BCC. These include:
•the size and location of the cancer
•how far the cancer has spread, including if it has metastasized
•whether or not the cancer is a recurrence of a previous BCC
BCC becomes advanced when it has spread deeper into surrounding tissues or to more distant tissues in the body. Since BCC is a slow growing cancer, this typically happens over a period of several years.
Advanced BCC is more difficult to treat than early BCC, often due to the location, size, and extent of the cancer. However, newer systemic treatments can help to improve your outlook when surgery or radiation therapy isn’t recommended.
Some subtypes of basal cell carcinoma are best to treat with a cream. When lesions are isolated to small, superficial spots on the trunk or extremities, we can treat them with a topical agent over an extended period of time (usually 4-6 weeks).
The dermatologist applies a topical agent to make the lesion sensitive to light, or injects the agent into the tumor. After allowing a short period of time for absorption, the dermatologist uses a blue light or pulsed-dye laser (or sometimes controlled natural sunlight), which causes a reaction that destroys the BCC.

Aug 2, 2023 · Patients with multiple AKs (including hyperkeratotic lesions) may benefit from a combination of topical and invasive treatments. Imiquimod 2.5%, 3.75%, and 5% creams are FDA-approved for the treatment of typical hyperkeratosis visible on the full face or scalp in immunocompetent adults.
Oct 21, 2022 · Basal cell carcinoma (BCC) is the most common type of skin cancer worldwide, often producing shiny lesions on the skin that can be (but are not always) discolored. It develops in the basal cells, which originate in the lowest level of the epidermis. Basal cell carcinoma accounts for about 80% of all non-melanoma skin cancer cases worldwide, and ...
