BCC most often occurs when DNA damage from exposure to ultraviolet (UV) radiation from the sun or indoor tanning triggers changes in basal cells in the outermost layer of skin (epidermis), resulting in uncontrolled growth.
Does basal cell carcinoma grow deep?
Basal cell carcinoma spreads very slowly and very rarely will metastasize, Dr. Christensen says. But if it’s not treated, basal cell carcinoma can continue to grow deeper under the skin and cause significant destruction to surrounding tissues. It can even become fatal.
How long does it take for basal cell carcinoma to grow?
The tumors enlarge very slowly, sometimes so slowly that they go unnoticed as new growths. However, the growth rate varies greatly from tumor to tumor, with some growing as much as ½ inch (about 1 centimeter) in a year.
What happens if Basal cell carcinoma is left untreated?
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.
Does basal cell carcinoma appear suddenly?
Basal cell carcinoma can appear suddenly. Unfortunately, when it shows up, it is often not recognized. Ignoring the early warning signs and symptoms of any skin cancer could lead to disfiguring scars or worsening conditions. If you see a sudden change in your skin, it is important that you have it checked immediately.
What is the average size of a basal cell carcinoma?
Average diameter of lesions was 12.2 mm; the biggest lesion measured 5.3 cm, the smallest 0.2 cm. Margins taken were 3 to 5 mm on cervico-facial area, 2-3 mm on noble areas as lips, ears, and eyelid and 5 to 10 mm on other areas.
What is considered a large BCC?
A size larger than 3 cm has been described as a high-risk feature . Notwithstanding the foregoing, this risk factor has been more accurately defined as 1 cm for head and neck tumors and more than 2 cm in other body areas .
Can you have basal cell carcinoma for years?
Basal cell carcinoma usually grows very slowly and often doesn’t show up for many years after intense or long-term exposure to the sun. You can get it at a younger age if you’re exposed to a lot of sun or use tanning beds.
Can basal cell carcinoma disappear on its own?
Basal cell carcinomas may appear to heal on their own but inevitably will recur.
What is the survival rate for basal cell carcinoma?
The prognosis for patients with BCC is excellent, with a 100% survival rate for cases that have not spread to other sites. Nevertheless, if BCC is allowed to progress, it can result in significant morbidity, and cosmetic disfigurement is not uncommon.
Which is more serious basal cell or squamous cell carcinoma?
Though not as common as basal cell (about one million new cases a year), squamous cell is more serious because it is likely to spread (metastasize).
Can basal cell carcinoma be itchy?
Basal cell carcinomas
Basal cell cancers usually develop on areas exposed to the sun, especially the face, head, and neck, but they can occur anywhere on the body. These cancers can appear as: Flat, firm, pale or yellow areas, similar to a scar. Raised reddish patches that might be itchy.
Is basal cell carcinoma hard to the touch?
Basal cell carcinoma can look like a group of shiny bumps
BCC can look like a group of small, shiny bumps that feel smooth to the touch.
How deep does basal cell carcinoma grow?
Superficial BCC mean depths ranged from 0.17 mm on the cheek to 0.40 mm on the foot. Combined superficial and nodular BCC subtype depths ranged from 0.63 mm on the thigh to 1.50 mm on the lip. Nodular BCC depths ranged from 1.36 mm on the eyelid to 1.98 mm on the hand.
Is BCC slow growing?
Basal cell carcinoma accounts for more than 90 percent of all skin cancers in the United States and is the most common of all cancers. Typically, it is a slow-growing cancer that seldom spreads to other parts of the body.
How can you tell if a spot is cancerous?
Redness or new swelling beyond the border of a mole. Color that spreads from the border of a spot into surrounding skin. Itching, pain, or tenderness in an area that doesn’t go away or goes away then comes back. Changes in the surface of a mole: oozing, scaliness, bleeding, or the appearance of a lump or bump.
