Doctors believe that exposure to UV rays of the sun, and tanning lamps/beds are the leading cause of melanoma. (2) If you are a young toddler and get a severe sunburn this may be a risk of skin cancer later in life. People in whom live in very warm places all year around such as Australia, Hawaii, and Florida have a larger chance of developing skin cancer, this is because their bodies are exposed to the sun daily. Also in some of the colder northern locations with the country having very light skinned people will also have a higher risk. Majority of the people that develop skin cancer are probably addicted to getting that perfect tan.
Also, there's a limit of protection that melanin can provide and that limit is higher in people with darker skin. The problem with someone's skin "getting darker" is there can be some damage that is being done. Some of the damaging effects of UV radiation is it can damage you're DNA, it can promote burns, and most commonly it promotes skin cancer. There are pros and cons about your skin getting darker, but I'd say it's safe to say wearing sunblock is always a good thing. My skin is darker because the melanocytes in the basale layer of epidermis are producing melanin to try to protect me from the harmful UV rays of the sun.
Sunlight has UV photons that we humans can’t see but can damage our skin. There are UVB rays and UVA rays, UVB rays are short wavelengths and don’t get deep into our skin so they are the main cause of sunburn + skin cancer but UVA rays have a longer wavelength and go deep into the skin and are the cause of early aging. (1) The Sun can Harm us because the sun emits dangerous UV rays, luckily the ozone layer absorbs most of these UV rays but the ones that do get to the surface can be dangerous to our skin and can cause Sunburn and ,in worse cases , Skin cancer. SunBurn is reddening,swelling of the skin and can cause blistering and peeling of the skin, when you spend a long time outside on a sunny day and you are exposed to UV rays our
UV radiation is a form of energy from natural and artificial sunlight. Excess amounts can cause damage to DNA in the skin. Although some argue tanning is good for you because it helps form a “base tan” and the UV exposure time is controlled. The truth is, each time you lay in a tanning bed, it increases the risk of developing skin cancer
Ozone is a product that can be produced naturally or it can be man made. It occurs in the stratosphere and the troposphere. The gas is composed of three oxygen molecules. Its chemical formula is O_3. Its pale blue and has a very strong smell.
The most uncommon type of skin cancer is known as melanoma. Although it’s unfamiliar it is the most dangerous type of skin cancer. It accounts for numerous types of deaths globally. In the United States, melanoma has been the cause of death for eighty one percent of the patients who are diagnosed with the sickness. Statistically, about fifteen percent of the patients diagnosed with melanoma live for about three to five years.
Melanoma: This type of skin cancer shows up in the pigment of the skin. Many are often not diagnosed early enough because they look like moles or other discolorations on the skin. However, Melanoma cancer will have irregular shapes and an oddly shaped border. There may also be wider variations in the colors. This type of cancer is the most dangerous as it does spread quickly to other areas in the body if it is not treated.
UV radiation is one of the most damaging factors that influences the health of the skin. It is more important in people than animals, however, due to their lack of furry covering and thus greater skin to sunlight exposure. Still, some animals with light pigmentation, thin fur, areas of bare skin or albinos will be at risk. Clinical studies have identified excessive sun exposure (and thus exposure to solar ultraviolet radiation) as a primary causative factor in various skin diseases including, premature ageing, inflammatory conditions, malignant and non-malignant tumours (Chang 2010; Schmitt 2011). This is due to a series of harmful biochemical reactions occurring in a process known as photoaging.
One million people in the U.S are diagnosed each year with some types of skin cancer. There are three major types of skin cancer, basal cell carcinoma, squamous cell carcinoma, and of course melanoma. Most people are more familiar with melanoma and because it is the least common they continue to think they won’t get cancer. The majority of skin cancer cases are basal cell carcinomas and squamous cells carcinomas. They are malignant meaning they will not spread to other parts of the body, and are usually able to be easily removed.
The large star that we call the Sun can be very helpful by providing us with vitamin D which enlightens our mood and keeps us optimists. Although in some cases sunlight exposure, especially too much of it can be very harmful to our health and skin. There are many different irritations that can be caused from too much sunlight, one of the most popular and common is sunburn. There was a survey and over one third of adults and up to 70% children had said that they have had sunburn in the past year (according to the cdc) 1. Sunburn is when your skin reddens, maybe swells up and sometimes even the blistering or peeling of the skin.
