What Causes Skin Cancer
Ultraviolet radiation from the sun is the number one cause of skin cancer, but UV light from tanning beds is just as harmful. Exposure to sunlight during the winter months puts you at the same risk as exposure during the summertime.
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.
Ultraviolet A and Ultraviolet B rays also affect the eyes and the skin around the eyes. Sun exposure may lead to cataracts, cancer of the eyelids, and possibly macular degeneration.
How To Spot The Signs Of Skin Cancer:
Check your moles regularly and keep a look out for any changes in shape, size or colour as listed above. If you detect any changes or abnormal moles, visit your GP as soon as possible. It is also worth paying a visit to a clinic such as The Mole Clinic for a full mole check, where a specialist nurse will examine every single mole from head to toe to identify any possible visually abnormal moles, with results available immediately. This should be something that is carried out annually particularly for people with lots of moles.
Melanoma Can Be Tricky
Identifying a potential skin cancer is not easy, and not all melanomas follow the rules. Melanomas come in many forms and may display none of the typical warning signs.
Its also important to note that about 20 to 30 percent of melanomas develop in existing moles, while 70 to 80 percent arise on seemingly normal skin.
Amelanotic melanomas are missing the dark pigment melanin that gives most moles their color. Amelanotic melanomas may be pinkish, reddish, white, the color of your skin or even clear and colorless, making them difficult to recognize.
Acral lentiginous melanoma, the most common form of melanoma found in people of color, often appears in hard-to-spot places, including under the fingernails or toenails, on the palms of the hands or soles of the feet.
The takeaway: Be watchful for any new mole or freckle that arises on your skin, a sore or spot that does not heal, any existing mole that starts changing or any spot, mole or lesion that looks unusual.
Acral lentiginous melanoma is the most common melanoma found in people of color.

How Can I Tell If I Have Skin Cancer
Skin cancer is actually one of the easiest cancers to find. Thats because skin cancer usually begins where you can see it.
You can get skin cancer anywhere on your skin from your scalp to the bottoms of your feet. Even if the area gets little sun, its possible for skin cancer to develop there.
You can also get skin cancer in places that may surprise you. Skin cancer can begin under a toenail or fingernail, on your genitals, inside your mouth, or on a lip.
Consider The Opposite To Be True
You know how I research now? I have a very simple method, and you would be shocked at how often and how quickly it works in getting to the bottom of things, truthwise.
I type a statement into DuckDuckGo search, that is the opposite of what they have everybody believing.
For example, the sun causing skin cancer seems fishy to me. So I type in, the sun does not cause skin cancer. And Ill be a blue-nosed gopher! A whole other world emerges from the stinking swamp! Proven, factual, scientific documentation, and everything!
But lets talk about what really causes cancer, and how the sun is entirely innocent. In fact, as you might imagine, with the complete opposite of what is commonly said and believed in mind, we find that not only does the sun cause skin cancer about as often as feeling joyful and elated is associated with being punched in the junk by Mike Tyson in his prime, the sun is actually nothing but really good for you!
That was a long sentence. I think it might be a record, for me
But we were talking about sunscreen being bad. Lets go into that, and then well find out about how sun exposure is good for you, and not bad .

A is for Asymmetry
Look for spots that lack symmetry. That is, if a line was drawn through the middle, the two sides would not match up.
B is for Border
A spot with a spreading or irregular edge .
C is for Colour
Blotchy spots with a number of colours such as black, blue, red, white and/or grey.
D is for Diameter
Look for spots that are getting bigger.
E is for Evolving
Spots that are changing and growing.
These are some changes to look out for when checking your skin for signs of any cancer:
- New moles.
- Moles that increases in size.
- An outline of a mole that becomes notched.
- A spot that changes colour from brown to black or is varied.
- A spot that becomes raised or develops a lump within it.
- The surface of a mole becoming rough, scaly or ulcerated.
- Moles that itch or tingle.
- Moles that bleed or weep.
- Spots that look different from the others.
Oral Medications For Advanced Bcc
It is rare for skin cancer to reach advanced stages, but when it does, oral medications may help. In addition to chemotherapy, targeted drugs may be used to treat advanced skin cancer. Targeted therapy means that the medication is able to directly target the cancer cells without destroying healthy cells. This can help to reduce side effects from treatment.
Vismodegib and sonidegib are hedgehog pathway inhibitors that work to prevent cancer cells from growing and spreading. The capsules are taken once per day and may be considered after surgery and other treatments. These medications come with several possible side effects and should never be taken during pregnancy since they can affect fetal growth.
Cetuximab is an EGFR inhibitor that can help to stop the spread of cancerous squamous cells. Its possible side effects include skin infections, diarrhea, mouth sores, and loss of appetite.

Are There Different Types Of Radiation In Sunlight
Yes. The types of radiation include:
- visible light, which gives us the colours we see
- infrared radiation which gives us the warmth we feel
- ultraviolet radiation
Except in extreme situations, neither visible light nor infrared radiation from sunlight causes health problems. However, ultraviolet radiation can cause harmful effects to the skin.
There are three basic types of ultraviolet radiation:
Table 1 summarizes the general features of each type.
|Table 1 Types of Ultraviolet Radiation and Their Features|
|Ultraviolet Radiation Type|
|Ultraviolet A radiation UVA, long-wave UV)||-not filtered out in the atmosphere -passes through glass -once considered harmless but now believed harmful over the long term -levels remain relatively constant throughout the day|
|Ultraviolet B radiation||-some filtered out in the atmosphere by the ozone layer -does not pass through glass -causes sunburn, tanning, wrinkling, aging of the skin and skin cancer -highest intensity at noontime|
|-filtered out in the atmosphere by the ozone layer before reaching earth -major artificial sources are germicidal lamps -burns the skin and causes skin cancer|
What Skin Cancer Looks Like
Skin cancer appears on the body in many different ways. It can look like a:
Changing mole or mole that looks different from your others
Non-healing sore or sore that heals and returns
Brown or black streak under a nail
It can also show up in other ways.
To find skin cancer on your body, you dont have to remember a long list. Dermatologists sum it up this way. Its time to see a dermatologist if you notice a spot on your skin that:

Does Sunlight Cause Skin Cancer
There is evidence that sunlight causes skin cancer. Skin cancer can be treated and cured without serious consequences. However, in some cases the condition can be life-threatening if not diagnosed in time.
Skin cancer is an occupational concern for people who work under the sun. The risk however, may be reduced through awareness of the problem, and by taking measures to prevent exposure to sunlight.
How To Spot Skin Cancer
Skin cancer is by far the most common type of cancer. If you know what to look for, you can spot warning signs of skin cancer early. Finding it early, when its small and has not spread, makes skin cancer much easier to treat.
Some doctors and other health care professionals include skin exams as part of routine health check-ups. Many doctors also recommend that you check your own skin about once a month. Look at your skin in a well-lit room in front of a full-length mirror. Use a hand-held mirror to look at areas that are hard to see.
Use the ABCDE rule to look for some of the common signs of melanoma, one of the deadliest forms of skin cancer:
AsymmetryOne part of a mole or birthmark doesnt match the other.
BorderThe edges are irregular, ragged, notched, or blurred.
ColorThe color is not the same all over and may include shades of brown or black, sometimes with patches of pink, red, white, or blue.
DiameterThe spot is larger than ¼ inch across about the size of a pencil eraser although melanomas can sometimes be smaller than this.
EvolvingThe mole is changing in size, shape, or color.
Basal and squamous cell skin cancers are more common than melanomas, but they are usually very treatable.
Both basal cell carcinomas and squamous cell carcinomas, or cancers, usually grow on parts of the body that get the most sun, such as the face, head, and neck. But they can show up anywhere.

The Worrying Skin Change That Could Mean You Have Breast Cancer
- 12:29 ET, Jan 6 2022
OVER 55,000 people are diagnosed with breast cancer each year in the UK and spotting it early can be life saving.
Some of the main symptoms include a lump or bump on the breast or armpit, but experts have now revealed a troubling symptom that can show up on the skin.
Writing in the New England Journal of Medicine , doctors in India explained the case of a 65-year-old man who presented at a dermatology clinic in Jhajjar.
The man explained how he had experienced a thickening of the skin over the left side of his chest and on his left arm.
He said that this had been happening for seven months – but that it did not give him any pain.
Medics examined the man and found that the skin on the left side of the chest and on the left nipple was sclerotic.
This is when the skin tissue hardens and tightens.
The medics also found multiple erythematous nodules on the left arm and lymphedema in the left arm and left axillary lymphadenopathy were present.
What Are The Main Signs Of Breast Cancer
For most women, the first sign or symptom of breast cancer is a lump or area of thickened tissue in their breast.
While 90 per cent of such lumps are not cancerous, it is vital to get them checked by your GP at the earliest opportunity detecting the disease early can mean treatment is more effective.
Here are the main signs to watch out for:
The experts explained: “The name derives from the resemblance of the condition to a breastplate of armor.”
The patient was referred to the oncology clinic and pallative chemotherapy was administered.
Carcinoma en cuirasse , is also known as scirrhous carcinoma.
It is a rare form of cutaneous metastasis of breast cancer and due to the rarity of cases, data on this type of cancer is limited.
This can make it hard to diagnose as it can often be mistaken for other skin conditions.
There are a range of treatments for breast cancer, with the type or combination used depending on how the cancer was diagnosed and the stage it has reached.
Once cancer has been diagnosed, you should be assigned a multidisciplinary team who will discuss the most suitable course of treatment.
As well as the stage and grade of the disease, doctors will take into consideration the patient’s general health and whether they have experienced the menopause.
The key treatments are:

Can Skin Cancer Spread To Other Parts Of The Body
Yes, it can. However, it depends on the type of skin cancer and its stage.
Non-melanoma skin cancers are less likely to spread. Basal cell carcinoma usually does not migrate to other parts of the body, but there is a small chance that squamous cell cancer will do so.
Melanoma skin cancer spreads more readily than non-melanoma, making it more dangerous. It can spread to the lymph nodes and, from there, to other organs in the body.
What Can I Do To Prevent Skin Cancer In My Child
The American Academy of Dermatology and the Skin Cancer Foundation advise you to:
Limit how much sun your child gets between the hours of 10 a.m. and 4 p.m.
Use broad-spectrum sunscreen with an SPF 30 or higher that protects against both UVA and UVB rays. Put it on the skin of children older than 6 months of age who are exposed to the sun.
Reapply sunscreen every 2 hours, even on cloudy days. Reapply after swimming.
Use extra caution near water, snow, and sand. They reflect the damaging rays of the sun. This can increase the chance of sunburn.
Make sure your child wears clothing that covers the body and shades the face. Hats should provide shade for both the face, ears, and back of the neck. Wearing sunglasses will reduce the amount of rays reaching the eye and protect the lids of the eyes, as well as the lens.
Dont let your child use or be around sunlamps or tanning beds.
The American Academy of Pediatrics approves of the use of sunscreen on babies younger than 6 months old if adequate clothing and shade are not available. You should still try to keep your baby out of the sun. Dress the baby in lightweight clothing that covers most surface areas of skin. But you also may use a small amount of sunscreen on the babys face and back of the hands.

Causes Of Skin Cancer
UV rays cause skin cancer by creating changes in the cells of your skin. In some cases, the UV rays cause direct damage to your cells. Tans and sunburns, for example, are both signs that UV rays have damaged your skin. In other cases, UV rays cause skin cancer indirectly, by weakening the immune system.
Many studies on skin cancer show that people who have suffered many severe sunburns in childhood are at greater risk of developing skin cancer. Family history, some chemical exposures, and immune dysfunction conditions can also create a greater risk of developing skin cancer.
How Is Skin Cancer Treated
Treatment of skin cancer depends on the type and extent of the disease. Treatment is individualized and is determined by the type of skin cancer, its size and location, and the patient’s preference.
Standard treatments for non-melanoma skin cancer include:
- Mohs surgery : Skin-sparing excision of cancer with complete peripheral and deep margin assessment.
- Electrodesiccation and curettage: Scraping away the skin cancer cells followed by electrosurgery.
- Drugs .
Standard treatments for melanoma include:
- Wide surgical excision.
- Sentinel lymph node mapping : to determine if the melanoma has spread to local lymph nodes.
- Drugs .
- Radiation therapy.
- New methods in clinical trials are sometimes used to treat skin cancer.
