UV Radiation Causing Cancer
Most forms of skin cancer are found on areas of the body that experience constant exposure to sunlight. The ultraviolet rays in sunlight are one main cause of skin cancer, but artificial sources of UV rays have also been proven to be a contributing factor.
Basal and squamous cell skin cancer are the most common forms of skin cancer. Multiple studies have shown that these cancers are almost always connected to large amounts of sun exposure. This can come from things like outdoor sports, performing something outdoors with little coverage from clothing, and getting multiple severe sunburns. You can see signs of skin cancer inside and outside of your body. Rough, thick, dry skin patches are common symptoms, but things

like liver spots can also be a sign. Melanoma, which is an uncommon but very serious form of skin cancer, has been linked to many of the same things as basal and squamous cell skin cancer. Some main causes are sunbathing, outdoor water activities, and high exposure to sun. It is highly unlikely for exposure to UV rays to cause cancer of your internal organs. The rays mainly affect your skin and outer layer of your body, but not much deeper. Despite this, sunlight can cause cancer in unusual places such as in the eye or lip. Like I previously stated, skin cancer is not only caused by exposure to sunlight, but can come from exposure to artificial UV rays too.
Indoor tanning is becoming a very popular “hobby”, but most people do not know, or do not care, about its dangerous side effects. Studies show that people who use tanning booths have a much higher chance of being diagnosed with skin cancer. If someone were to start tanning indoors before they turn 30 or 25, the risk of them getting Melanoma peaks, and if they start tanning before they turn 20 or 25, they are much more likely to get basal and squamous cancer.
Indoor tanning is not the only dangerous source of artificial UV rays. Welding and metal work can cause melanoma of the eye, and the use of UVA for medical treatment raises your chance of getting squamous cell cancers.
Scientists have performed many different tests and studies to learn more about high exposure to UV. Close observation of cells have shown that sunlight, natural or artificial, can cause mutations or DNA damage in cells. This can lead to further damage which will then be passed down through generations. Another study scientists perform is on animals. Scientist will expose your typical lab animals to UV rays, and this test typically results in skin cancer on the animal. These studies have been performed with UVA, UVB, and UVC, and they have all proven
dangerous. Trusted organizations are responsible to determine carcinogens, or substances that cause cancer or simply help it grow. The International Agency for Research on Cancer (IARC) and The National Toxicology Program (NTP) have both classified UV radiation as a human carcinogen. One of the biggest issues with skin cancer is spreading awareness. Many people who use tanning beds do not know the dangers that come with it. The IARC and the NTP have classified sunlamps and sunbeds as carcinogens. Also, the FDA forces tanning beds to have a caution label. This may not stop people from using these dangerous beds, but it will at least knowledge them about what they are doing to their body every time they step in a tanning bed.

Have you ever seen commercials on television advertising allergy medications? The advertisement states that taking the medication can cause abnormal sleep patterns, nausea, vomiting, diarrhea, itching, watery eyes, rashes, and headaches. A conclusion could be made that the side effects of the product would be much worse than the allergy problem. However, people still purchase the product. The lengths an average person will go in order to get a quick fix is amazing. It is this way of thinking that makes tanning beds so popular. Over the last decade, cancer causing tanning beds have given self-image issues to people across the world.
Skin cancer is a significant public health issue in Australia. Exposure to ultraviolet radiation emitted by the sun in the UVA and UVB wavelengths is the primary cause. Australia has been a world leader in efforts to protect the ozone layer, the main line of defense against ultraviolet radiation emitted by the sun. Ultraviolet radiation induces the formation of thymine dimers that cause mutation of skin cells if not repaired before DNA replication. Mutations of tumor suppressor genes can lead to uncontrolled cell growth. Ultraviolet radiation also causes immunosuppresion that allows skin cancers to become established. Basal cell carcinoma, squamous cell carcinoma, and melanoma are types of skin cancer caused by sun exposure, though each form is associated with a different pattern of exposure. Australia has the highest rate of skin cancer in the world, due to a combination of tropical latitude, fair-skinned population, outdoor lifestyle, and high amount of ambient ultraviolet radiation. Widespread opinions about tanning and health benefits of sunlight lead many Australians to intentionally overexpose themselves to the sun. State cancer councils have developed sun safety and awareness campaigns, such as “Slip! Slop! Slap!” and “SunSmart,” to educate the population about sun exposure and encourage early detection of skin cancers. Gradual changes in knowledge and behavior indicate that the fight against skin cancer can be won.
Basil Cell Carcinoma is the most common form of skin cancer. It usually begins as a mole (skin melanoma) on your body; however this cancer can also begin in other areas such as your eye or intestines. This cancer is also the most dangerous type of skin cancer. If diagnosed and treated early, it is almost always curable. There are roughly 2.8 million cases of this cancer diagnosed each year
Tanning can be harsh to your skin. The light coming from the sun contains different wavelengths of ultra violet (UV) waves. The two types of waves concerned about are UVA rays and UVB rays. UVA rays are long waves that cause more damage than a UVB ray. UVA rays penetrate deeper into your skin and cause tanning (“The Dangers of”). More and more exposure to UVA rays can cause permanent damage ...

Indoor Tanning beds are controversial and not without risk. The positives and negitives should be told straight up when going to a tanning salon. The risk of developing melanoma skin cancer from over exposure to UVA and UVB radiation has been proven and well documented by the medical field and research. There are a few benefits of using indoor tanning beds such as a positive mood boost, healing of some types of skin disorders and in the production of vitamin D. One must be educated about the use of indoor tanning before deciding to indulge and weigh the risks and benefits before making the decision to go tanning long term.
Informing you on a everyday thing some girls do, which is tanning. Two main questions you have to ask yourself is it healthy? And will it cause skin cancer ? Well to answer both of those questions you can get skin cancer, and it is healthy for you. Only some parts of it is healthy though, not all of it. And thats what we will be explaining in this paper today. We both do tan so we’re not against it and see the good thing about tanning. Not everyone has to be on our side, some people may like tanning naturally better to begin with.
0.20 and 0.29 UV-C are harmful to living things. These wavelengths have the ability to cause mutations to living cells, and even kill living cells. It also has the ability to damage your eyes.Most of the UV-C wavelengths are absorbs in the ozone. (But with our ever depleting ozone layer, what happens when the ozone layer is not there anymore?)
Have you ever seen someone who was so usually tan that their skin almost looked leathery? Or someone who just couldn't go a day without tanning? On average over one million people spend their money on tanning. Unfortunately, this isn't just a fun hobby, these people are at risk. People who tan excessively are what dermatologist call tanorexics. People who are tanorexics see their complexion and wish it were different. They feel self conscious when others are more tan than they are. Although wanting to be tan may not always be a bad thing many people take it to far. Tanorexia is a tanning addiction most young adults have that is caused by mental illnesses and is also a replacement for drugs and alcohol, and leads to horrible diseases such as skin cancer.
Every young girl or woman in America wants their image to look like a Barbie doll. This perfection includes being extremely skinny and extremely tan. In order to achieve this Barbie-like image women and men have been using tanning beds or spray tans to alter their appearance. Tanning beds can prove to be very harmful to a person’s health and can cause extremely dangerous medical conditions, including the most deadly type of cancer. However, fake tans can also be used in a positive way for some people who use them sparingly.
Surprisingly, even with these astonishing numbers people still continue to put themselves at risk everyday. The solution to all this is very simple, we all need to wear sunscreen when planning to expose ourselves to the sun. There are also other everyday preventive measures that we can take to decrease our chances of harmful exposure to the sun. It is always helpful to wear a shirt and a hat with a broad brim. Wear sunglasses that absorb 99%-100% of UV rays to help your block your eyes and the skin around your eyes from these harmful rays. The two most important things for most people who like to tan are to seek shade frequently and to never use tanning beds. You can put your body at even more of a higher risk of contracting skin cancer when staying in the constant heat.
UV radiation causes significant damage to human skin, in the form of sunburns, aging, skin cancer, and nonmelanoma tumors. Human skin damage is primarily a result of tanning. The
Skin cancer is a disease where cancer (malignant) cells are found on the outer layer of the skin (epidermis). The three types of cells found in the epidermis are squamous cells, basal cells, and melanocytes. These cells in time grow to be cancerous. Thus, the three types of skin cancers are squamous cell, basal cell, and melanoma. Melanoma is the most deadliest and destructive type of cancer. (“Skin Cancer” infotrac.com) The number of people with melanoma has risen in Scotland from 3.5 in 1979 to 10.6 per 100,000 in 1998 for men and 7.0 to 13.1 for women. (Miller 945) Squamous cell and Basal cell skin cancer can kill up to 2,200 people a year in the United States. (Sommerfield SIRS.com) Basal cell, being the most common type of skin cancer, is the cancer that about 75 percent of the people have. (“Skin Cancer “ infotrac.com) Melanoma is mostly seen in older men but ever since tanning came in during the 1970’s, it has increased in women 60 percent around the ages 15-29 over the past three decades.(Sommerfield SIRS.com) “And basal cell and squamous cell cancers are increasing at a rate of about 5 percent per year”(Sommerfield SIRS.com).
Cutaneous Melanoma skin cancer is known to be the most dangerous form of skin cancer. Melanoma begins when malignant cancer cells form in the melanocytes. These melanocytes are melanin-producing cells found in the outermost layer of the skin, the epidermis. Increased exposure to ultraviolet radiation from the sun or tanning beds causes DNA damage that can lead to the proliferation of such cancer cells and eventually form malignant tumors. There are approximately 10,130 deaths associated with melanoma annually. With an increase in skin cancer, specifically melanoma, it is important to understand the types, signs and symptoms, possible treatments, as well as early prevention.
Skin cancer is caused by a single cell becoming cancerous and growing and eventually forming a lump. It usually happens to areas of your body exposed to too much sunlight and when it occurs it usually forms a dark lesion on your body (or a dark spot with speckles on it). The most common types of skin cancer are melanoma, basal cell carcinoma, atypical fibroxanthoma, and kaposi sarcoma. Symptoms of the disease are a mole that changes in color or size or a dark spot on body. Those are some common facts about skin cancer.
