Hope For Aggressive Forms Of Melanoma
Importantly, the research also revealed that 80 percent of tumors from melanoma patients had high levels of GDF6, and the higher the levels of this protein were, the more aggressive the cancer was.
This is important because it means melanoma cells are dependent on GDF6 for survival, says Venkatesan. Without GDF6, melanoma cells do not survive.
What is so exciting about this discovery is that it opens up a completely new therapeutic target for investigation. None of the current therapies on the market target GDF6 or its pathway. For patients with very aggressive or treatment-resistant forms of this cancer, this is very important.
Craig J. Ceol, Ph.D.
As Ceol continues, here is great therapeutic potential when you combine a drug targeting GDF6 with current therapeutics. This is why he and his colleagues are currently working on a way to switch off the gene in a way that could be used therapeutically.
He adds, Because GDF6 is a type of protein that acts outside the cell, it makes it much easier to target therapeutically. Were already exploring how to use monoclonal antibodies to inhibit GDF6.
Ask Your Doc About Sun
If you frequently eat nutrient-rich produce in a wide array of colors, youre already providing your body with lots of supportive vitamins and minerals. But some supplements might help kick your skin protection up a little bit.
Dr. Herman says that research currently supports two supplements. The first is Heliocare, which contains a plant extract called Polypodium leucotomos extract that may help protect your skin from free radicals. Then, theres niacin , which may reduce the risk of squamous-cell and basal-cell skin cancers. Before trying a new supplement, talk to your dermatologist to see if it make sense for you.

On This Page
Cancerprevention is action taken to lower the chance of getting cancer. By preventing cancer, the number of new cases of cancer in a group or population is lowered. Hopefully, this will lower the number of deaths caused by cancer.
To prevent new cancers from starting, scientists look at risk factors and protective factors. Anything that increases your chance of developing cancer is called a cancer risk factor anything that decreases your chance of developing cancer is called a cancer protective factor.
Some risk factors for cancer can be avoided, but many cannot. For example, both smoking and inheriting certain genes are risk factors for some types of cancer, but only smoking can be avoided. Regular exercise and a healthy diet may be protective factors for some types of cancer. Avoiding risk factors and increasing protective factors may lower your risk but it does not mean that you will not get cancer.
Different ways to prevent cancer are being studied.

What Causes Skin Cancer
Almost all skin cancers in Australia are caused by too much exposure to UV radiation. This is the part of sunlight that causes tanning, sunburn and skin damage over time. UV radiation also comes from non-natural sources such as sun beds .
While anyone can get skin cancer, it is more common if you are older. The risk is also higher if you have:
- previously had skin cancer or have family history of skin cancer
- fair or freckled skin, particularly if it burns easily or doesnt tan
- red or fair hair and light-coloured eyes
- a weakened immune system
- sunspots or irregular moles on your body
- worked, played sport or spent leisure time in the sun
- actively tan or use sun beds
If you have olive or dark skin, your skin produces more melanin, which protects against UV radiation. However, its still possible for you to develop skin cancer.
How Do I Know When To Reapply My Sunscreen
You can purchase sunscreen reminder stickers called sundicators . These are stickers that will change colour to remind you when you need to re-apply sunscreen.

Sun Safety And Uv Prevention Tactics
UV exposure increases your risk for all skin cancers. When youre outdoors, its helpful to put something between the sun and your skin. Take advantage of shade, an umbrella at the pool or beach, a hat , sunglasses, keeping your shirt on while mowing, and so on.
If you know your skin will be exposed, use a broad-spectrum SPF 30 sunscreen. Dont be stingy with applying the sunscreen you have to use a generous layer to achieve the SPF on the label. Reapply the sunscreen every couple of hours if youll be outside for a long time, and more often if youre swimming or sweating.
We strongly advise that you avoid tanning booths, which are linked to increased risk of melanoma.
Its true that previous sunburns increase the risk that youll get skin cancer someday. However, if you are more careful now, youre doing your skin a big favor. You will be less likely to encounter the final straw that turns damaged skin cells into cancerous ones. Focus on keeping your skin healthy now, and check your skin regularly so that if cancer turns up, you can catch it early when its far easier to treat and cure.
What Are The Risk Factors For Skin Cancer
Anyone can get skin cancer, but the Centers for Disease Control and Prevention outlines several characteristics that can put people at a greater risk:
- Lighter natural skin color
- Certain types of moles or a large number of moles
- A family or personal history of skin cancer
- Older age
Dawn Holman, MPH, a behavioral scientist in epidemiology and applied research at the CDCs division of cancer prevention and control, stresses that even though risk factors are higher in people with fair skin, people with all skin types are susceptible to skin cancer and can benefit from sun protection and staying alert to changes in their skin.

Diagnosis Of Skin Cancer
It is important to check your skin regularly and check with your doctor if you notice any changes.
In the majority of cases, your GP will examine you, paying attention to any spots that may look suspicious. Your GP may perform a biopsy . In some cases your GP may refer you to a specialist, such as a dermatologist, if necessary.
Cancer Prevention Clinical Trials Are Used To Study Ways To Prevent Cancer
Cancer preventionclinical trials are used to study ways to lower the risk of developing certain types of cancer. Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer.
The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include eating fruits and vegetables, exercising, quitting smoking, or taking certain medicines, vitamins, minerals, or food supplements.

Get Skin Cancer Screenings
Even if you dont have any skin concerns, its a good idea to have yearly skin cancer screening checks with a dermatologist. Theyll be able to see areas of your body you cant easily monitor.
A dermatologist will also be able to evaluate any moles or other skin growths for the possibility of skin cancer. If a mole has suspicious features and looks like it may be malignant , removing it early may prevent it from spreading to other areas of your body.
Treatment Of Stage Iii Melanoma That Can Be Removed By Surgery
For information about the treatments listed below, see the Treatment Option Overview section.
Treatment of stage III melanoma that can be removed by surgery may include the following:
- Surgery to remove the tumor and some of the normal tissue around it. Skin grafting may be done to cover the wound caused by surgery. Sometimes lymph node mapping and sentinel lymph node biopsy are done to check for cancer in the lymph nodes at the same time as the surgery to remove the tumor. If cancer is found in the sentinel lymph node, more lymph nodes may be removed.
- Surgery followed by immunotherapy with immune checkpoint inhibitors if there is a high risk that the cancer will come back.
- Surgery followed by targeted therapy with signal transduction inhibitors if there is a high risk that the cancer will come back.
- A clinical trial of immunotherapy with or without vaccine therapy.
- A clinical trial of surgery followed by therapies that target specific gene changes.

Prognosis For Skin Cancer
It is not possible for a doctor to predict the exact course of a disease. However, your doctor may give you the likely outcome of the disease. If detected early, most skin cancers are successfully treated.
Most non-melanoma skin cancers do not pose a serious risk to your health but a cancer diagnosis can be a shock. If you want to talk to someone see your doctor. You can also call Cancer Council 13 11 20.
Where Does Skin Cancer Develop
Skin cancer is most commonly seen in sun-exposed areas of your skin your face , ears, neck, arms, chest, upper back, hands and legs. However, it can also develop in less sun-exposed and more hidden areas of skin, including between your toes, under your fingernails, on the palms of your hands, soles of your feet and in your genital area.

Sun Exposure: The Electromagnetic Spectrum
Most often, ultraviolet light is at the center of conversations around skin cancer, because its is the number one cause of skin cancer.
Electromagnetic radiation comes in wavelengths of light. Only some are visible to the human eye, and wavelengths along the electromagnetic spectrum affect the skin in different ways.
UVB Shortwave ultraviolet B rays cause sunburns and damage the DNA in skin cells, which can ultimately lead to skin cancer. UVB rays are a tiny portion of the electromagnetic spectrum, but they are traditionally where most sunscreen companies focus their attention.
UVA Long-wave ultraviolet A rays result in tanning and premature signs of aging. UVA rays are prevalent in all kinds of weather and can even penetrate glass. When researchers realized UVA rays also contribute to skin cancer, they developed broad-spectrum sunscreens to protect against it, too, with the added benefit of preventing wrinkles and dark spots.
Protecting against both UVA and UVB rays is an important part of skin cancer prevention. , an assistant professor of dermatology at NYU Langone Health in New York City and a dermatologic surgeon, says broad-spectrum is a key phrase to look for when purchasing sunscreen because it protects against both UVA and UVB rays.
Skin Cancer Treatment Options
If your skin cancer is biopsy-confirmed, your dermatologist will recommend the treatment options best suited to your skin cancer type based on the location, size, and features noted on the biopsy specimen. Most skin cancer treatment is done on an outpatient basis, typically by one of the following three methods:
- Mohs micrographic surgery: For many non-melanoma skin cancers, such as basal cell carcinoma and squamous cell carcinoma, the preferred treatment option is Mohs surgery. In this precise procedure, a small disc of tissue is removed around the skin cancer and prepared for immediate microscopic evaluation. The Mohs surgeon checks all of the edges of what was removed for cancer cells, while the patient waits. Once the edges are cancer-free, the wound is repaired. The goal of Mohs surgery is to provide a high cure rate and to remove the cancer while leaving as much normal, healthy skin behind as possible.
- Wide-local excision:The doctor excises the entire skin cancer together with a safe border of surrounding normal skin.
- Electrodessication and Curettage : For superficial non-melanoma skin cancers, ED& C provides high cure rates with minimal scarring. Because cancer cells scrape away more easily than normal tissue, a trained dermatologist can scrape away the cancerous cells using a tool called a curette and leave only normal skin behind.

Ways To Tell If Your Treatment Plan Is Working
During chemotherapy treatment, your doctor will order regular scans and blood work to monitor your treatment progress.
Imaging is used in standardized testing called RECIST, which stands for “response evaluation criteria in solid tumors.” RECIST is used with solid tumors to assign scores to how the patient is responding to treatment. They take scans to monitor the tumor’s size and spread to other parts of the body.
The doctors then classify the tumor’s response to treatment as:
- Complete response : The tumor has completely disappeared from the scans.
- Partial response : The tumor has shrunk by 30% or more from before treatment.
- Stable disease : The tumor doesn’t fall into any of the other categories cancer has not grown or shrunk during treatment.
- Progressive disease : The tumor has grown by 20%, or more or more tumors have developed.

Australian Researchers Say They Can Stop Skin Cancer Spreading
While 90 percent of people can be cured by having the primary cancer of melanoma removed through surgery, it spreads in the other 10 percent because it is detected too late.
SYDNEY – A combination of new treatments can stop the world’s deadliest form of skin cancer – melanoma – in its tracks and halt its spread to other organs, researchers said on Monday.
Results from two international drug trials conducted by the Sydney-based Melanoma Institute Australia proved successful in preventing the disease spreading in stage three patients whose tumours had been surgically removed.
Until now, these patients were at a high risk of the disease becoming advanced and fatal.
“Results from these clinical trials suggest we can stop the disease in its tracks effectively preventing it from spreading and saving lives,” the institute’s medical director Georgina Long said in research published in the New England Journal of Medicine Monday.
“Our ultimate goal of making melanoma a chronic rather than a terminal illness is now so much closer to being achieved.”
One in every three cancers diagnosed is a skin cancer, according to the World Health Organisation, with Australia having among the highest incidences of melanoma in the world. One Australian dies from it every five hours.
While 90 percent of people can be cured by having the primary cancer removed through surgery, it spreads in the other 10 percent because it is detected too late.
What Are The Different Types Of Skin Cancer
When skin cancer develops, the type of cells it affects determines what kind of cancer it is. For example:
- Skin cancer that develops in the basal cells is known as basal cell carcinoma. Its the most common form of skin cancer and is also the slowest growing.
- Skin cancer that develops in the squamous cells is known as squamous cell carcinoma. It often shows up as red, scaly lesions or sores on the skin. This type of skin cancer usually isnt life threatening, but it can become dangerous if its left untreated.
- Skin cancer that develops in the melanocytes is called melanoma. This is the most dangerous type of skin cancer. Its more likely to spread than basal and squamous cell skin cancers. It causes the majority of skin cancer deaths each year.
While some types of skin cancer have a genetic component, there are a lot of things you can do to prevent skin cancer from developing.
