Basal cell carcinoma (BCC), a common malignancy, arises most often in sun-exposed areas but does rarely occur in non-sun-exposed sites. Prior tissue injury, especially sharp trauma and chronic inflammation, increases the risk of BCC.
Can skin cancer happen without sun exposure?
It can be.” In fact a skin cancer in a hidden part of the body is actually more likely to be a melanoma, which is the most dangerous type of skin cancer. But non-melanoma skin cancers – basal cell and squamous cell cancers – can sometimes occur in non-sun-exposed areas too.
Can you get melanoma in places that don’t see the sun?
Melanomas can also develop in areas of your body that have little or no exposure to the sun, such as the spaces between your toes and on your palms, soles, scalp or genitals. These are sometimes referred to as hidden melanomas because they occur in places most people wouldn’t think to check.
Is basal cell cancer caused by the sun?
Most basal cell and squamous cell skin cancers are caused by repeated and unprotected skin exposure to ultraviolet (UV) rays from sunlight, as well as from man-made sources such as tanning beds. UV rays can damage the DNA inside skin cells.
Are all skin cancers caused by the sun?
More than 90 percent of skin cancers are caused by sun exposure . Skin cancers are divided into two major groups: nonmelanoma and melanoma. Nonmelanoma skin cancers (usually basal cell and squamous cell) are the most common cancers of the skin.
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.
Can you pick off a basal cell carcinoma?
Yes, you might be able to pick this crusty lesion off with your fingers. But it would grow back. The right thing to do is see a dermatologist and have it removed.
Are skin cancers itchy?
Skin cancers often don’t cause bothersome symptoms until they have grown quite large. Then they may itch, bleed, or even hurt. But typically they can be seen or felt long before they reach this point.
Are all cancers carcinomas?
Not all cancers are carcinoma. Other types of cancer that aren’t carcinomas invade the body in different ways. Those cancers begin in other types of tissue, such as: Bone.
How do you know if you have melanoma on face?
Melanoma signs include:
- A large brownish spot with darker speckles.
- A mole that changes in color, size or feel or that bleeds.
- A small lesion with an irregular border and portions that appear red, pink, white, blue or blue-black.
- A painful lesion that itches or burns.
How long does it take for basal cell carcinoma to develop?
Because basal cell carcinoma often takes decades to develop, the majority of basal cell carcinomas occur in older adults. But it can also affect younger adults and is becoming more common in people in their 20s and 30s.
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.
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.
