You asked: What is the science behind melanoma?

What is the science behind skin cancer?

Research has shown that these skin cancers generally develop because of over-exposure to UV radiation (from the Sun or from sunlamps or tanning beds). Each time your unprotected skin is exposed to UV, the UV causes changes to take place in the structure of the genes and in the behaviour of the cells.

What happens in the cell cycle that causes melanoma?

The body can often correct mutations, but if it doesn’t, the mutation creates an abnormal protein or prevents one from forming, which in turn causes a cell to multiply uncontrollably and become cancerous. Melanoma develops when melanocytes (the cells that produce pigment), mutate, multiply, and become cancerous.

Can a campfire cause skin cancer?

Firefighters risk their lives every day, whether running into burning buildings or battling out-of-control wildfires, but the menace doesn’t come just from the fire. They may face an increased risk for developing melanoma, the most dangerous of the three most common types of skin cancer.

How does UV light cause melanoma?

How can UV cause skin cancer? Too much UV radiation from the sun or sunbeds can damage the DNA in our skin cells. DNA tells our cells how to function. If enough DNA damage builds up over time, it can cause cells to start growing out of control, which can lead to skin cancer.

Is melanoma dominant or recessive?

In fair-complexioned individuals worldwide, the majority of melanoma cases are related to environmental factors such as excessive ultraviolet radiation (sun exposure). However, about 5-10% of melanoma cases are inherited in an autosomal dominant fashion.

Who is more prone to melanoma?

Melanoma is more likely to occur in older people, but it is also found in younger people. In fact, melanoma is one of the most common cancers in people younger than 30 (especially younger women).

How Can melanoma be prevented?

Limit your exposure to ultraviolet (UV) rays

The most important way to lower your risk of melanoma is to protect yourself from exposure to UV rays. Practice sun safety when you are outdoors.

Where does melanoma usually start?

Melanomas can develop anywhere on the skin, but they are more likely to start on the trunk (chest and back) in men and on the legs in women. The neck and face are other common sites.

Is melanoma genetic?

Few people inherit melanoma genes

About 10% of melanomas are caused by a gene mutation (change) that passes from one generation to the next. Most people get melanoma for other reasons. The sun, tanning beds, and tanning lamps give off ultraviolet (UV) rays. These rays are known to damage our skin.

How does melanoma make you feel?

Melanoma can cause pain in the bones where it’s spread, and some people—those with very little body fat covering their bones—may be able to feel a lump or mass. Metastatic melanoma can also weaken the bones, making them fracture or break very easily. This is most common in the arms, legs, and spine.
