Can you get melanoma on non sun exposed skin?

Can you get melanoma in areas not exposed to the sun?

Melanoma is a type of cancer which usually occurs on skin that has been overexposed to the sun. However, melanomas can also occur on parts of the body that have never been exposed to the sun.

What causes melanoma besides the sun?

Cumulative sun exposure causes mainly basal cell and squamous cell skin cancer, while episodes of severe blistering sunburns, usually before age 18, can cause melanoma later in life. Other less common causes are repeated X-ray exposure, scars from burns or disease, and occupational exposure to certain chemicals.

What type of skin cancer is not caused by sun exposure?

Melanoma is not caused by sunlight.

Can you have melanoma for years and not know?

How long can you have melanoma and not know it? It depends on the type of melanoma. For example, nodular melanoma grows rapidly over a matter of weeks, while a radial melanoma can slowly spread over the span of a decade. Like a cavity, a melanoma may grow for years before producing any significant symptoms.

How long does melanoma take to spread?

Melanoma can grow very quickly. It can become life-threatening in as little as six weeks and, if untreated, it can spread to other parts of the body.

Is the sun the only way to get skin cancer?

Continuous exposure to the sun without the protection of sunscreen, hats, lightweight long-sleeved clothing, and other barriers increase the risk of developing skin cancer as well. Although long-term, unprotected sun exposure is a leading cause of skin cancer, it’s not the only cause.

Does lack of sun cause moles?

However, moles are often found on areas of the body that are not exposed, which suggests that factors other than ultraviolet radiation from the sun, perhaps hormones or other biologic processes, are involved in triggering the development of acquired melanocytic nevi and dysplastic nevi.

How long does it take for the sun to damage your skin?

The skin of people who are sensitive to light can’t protect itself from UV radiation for long. In very fair-skinned people, UV radiation starts becoming harmful after about 5 to 10 minutes.

What percent of melanoma is caused by sun?

An estimated 7,180 people will die of melanoma in 2021. Of those, 4,600 will be men and 2,580 will be women. The vast majority of melanomas are caused by the sun. In fact, one UK study found that about 86 percent of melanomas can be attributed to exposure to ultraviolet (UV) radiation from the sun.

How do you know if melanoma has spread?

Some — but not all — patients need testing. Testing can help your dermatologist discover whether the melanoma has spread beyond the skin. Medical tests that you may need include blood work and imaging tests like an MRI scan, CAT scan, or x-ray.

What type of skin cancer is caused by sun?

Basal and squamous cell skin cancers are the most common types of skin cancer. They start in the top layer of skin (the epidermis), and are often related to sun exposure. Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer cells.

Which skin cancer is the second most common form seen in patients?

SCC is the second most common type of skin cancer. People who have light skin are most likely to develop SCC. This skin cancer also develops in people who have darker skin. SCC often looks like a red firm bump, scaly patch, or a sore that heals and then re-opens.
