AUSTRALIA’S Olympic swimming gold medallist, Cate Campbell, recently posted a photo on her Instagram account of a large scar on her arm where a stage I melanoma had just been removed. This follows a celebrity trend of posting content regarding their respective skin cancer experiences; including Hugh Jackman, who has had five basal cell carcinomas removed from his face and AFL Hawthorn club captain, Jarryd Roughead, who has publicly shared his battle with metastatic melanoma.
Their message is simple: get your skin checked. This is the same message that we advocate for as dermatologists. Unlike breast, bowel and cervical cancers, there is currently no population-based screening program for melanoma.
Australia has the unenviable reputation of being the melanoma capital of the world, with the highest age-standardised incidence rates for invasive melanoma. The estimated number of new cases of melanoma to affect Australians in 2019 is 15 229. In fact, melanoma is the most common cancer among Australians aged 15–39 years. If caught early (stage I), the 5-year survival rate for melanoma is high (99.2%). However, this rate decreases to only 26.2% for Australians diagnosed with stage IV melanoma.

Early detection is the key to saving lives. In order to achieve our vision of a world without melanoma, a multipronged approach will be required.
While there is no recommendation for a population-based screening program, there is new evidence from the University of Queensland (UQ) Dermatology Research Centre showing that an impact could be made by focusing surveillance on people at highest risk. UQ researchers have discovered that Australians with a mole count of 20 or more, who also possess the “red hair” gene (MC1R), have a 25-fold increased risk of developing a melanoma in their lifetime. The interplay of knowledge of genetic risk combined with other known risk factors should allow for the development of targeted surveillance programs.
Delivery of specialist dermatology services in regional, rural and remote areas is particularly challenging.
The sheer burden of melanoma in Australia affords Australian dermatologists the opportunity to lead advances in melanoma detection worldwide. Commencing this year, the Australian Cancer Research Foundation Australian Centre of Excellence in Melanoma Imaging and Diagnosis is pursuing a world-first approach to tackling the burden of melanoma, with the aim of achieving a “World Without Melanoma”.
Led by UQ, together with the University of Sydney and Monash University, this work will implement cutting edge, three-dimensional (3D) imaging technology with a telemedicine network to improve the early detection of melanoma.
This project will see 15 3D whole-body imaging machines positioned in capital and regional centres across Queensland, New South Wales and Victoria, with the potential to expand the network Australia-wide in the future. The machines will be linked with innovative telemedicine capabilities, enabling earlier detection of melanoma with the aim of ultimately saving lives.
Using the latest imaging system, which takes a 3D whole-body image in milliseconds, will allow us to significantly improve lesion identification and tracking, in combination with greatly reduced appointment time and health care costs.
Three-dimensional total body data will be transmitted from 3D imaging systems in regional and rural Australia to centralised image storage repositories. This centralised storage repository will allow dermatologists, or suitably trained general practitioners (GPs) with subspecialty knowledge, to review the patient images independent of time, location, or population density parameters. This will provide enhanced access to specialist services for those living in rural and remote areas, and it is hoped this will improve survival rates dramatically by allowing the disease to be detected early.
Devices will change the daily practice of dermatologists. This technology will facilitate improved triage capabilities for patients who require more specialist attention and care.
Smartphone dermoscopic imaging with built-in artificial intelligence (AI) will most likely prove the most accessible method for future skin lesion analysis. These technological advances will serve as enablers for the dermatology community.
Importantly, technology is not a replacement for a dermatologist, but rather, another tool to allow us to best care for our patients.
It is estimated that each of the 15 3D imaging machines will provide 3000 examinations each year, generating approximately 45 000 images from all systems, annually. This will produce a large dataset of skin images, adding to the capacity to inform other clinical studies, including the computation of AI algorithms to support clinical decision making.
AI and its adoption in dermatology is proceeding rapidly, such as for identifying the potential characteristics of melanoma, and is being integrated into software for various types of imaging platforms.
In the meantime, however, the number of new cases of melanoma in Australia is predicted to continue to rise, placing a substantial burden on Australia’s health care system. Our profession also faces workforce shortages nationwide.
According to the Department of Health, the Australian dermatology workforce is projected to be short of at least 90 specialist dermatologists by 2030, representing a 14% deficit of the projected demand for dermatology services.
To meet the skin health needs of our Australian population, we need to rapidly expand our training programs and increase the number of specialist dermatologists available. This requires more funding for dermatology departments in public hospitals across the country. Increasingly, health services have assigned dermatology services as a low priority, which has subsequently resulted in a funding shortfall. Increased dermatology training capacity will only be achieved when public hospital dermatology services are appropriately prioritised to meet the community’s needs. State and territory support for public hospitals, complemented with federal investment to explore new models of training, is essential to address the dermatology workforce shortage.
Continued funding for outreach services nationwide is critical to meet the health service needs of all Australians. This must also be accompanied by measures to increase dermatology services in larger regional centres. Investment in new technology, such as teledermatology, will help enable the delivery of services to rural and remote communities. Specialised consulting and surgical services provided by dermatologists in the private sector removes a huge burden on the public hospital system.
One of the Australasian College of Dermatologists’ clear objectives is to ensure high quality, dermatologic care is available to meet the community’s needs. Our College is building enduring and cooperative relationships with community groups to help better understand their members, and to guide our activities. Crucially, these groups should be consulted to shape future government health policy.
However, it’s important not to forget that age old saying that “prevention is better than cure”. Skin cancer is primarily preventable. Using a combination of sun protection measures, Australians can take positive steps each day to reduce their risk of developing the disease.
Particularly, appealing to the younger generations and reinforcing the importance of caring for the skin early in life should generate better skin health outcomes in this demographic.
It’s our job as clinicians to keep reminding Australians of this crucial message.

A full time primary skin cancer doctor who does 5 hours/day consulting and 3 hours/day procedures get through 20 skin checks a day and ~5000 per year. So ~1.5 machines will be needed to replace one doctor – and the decision will still need to be made by the doctor…. sounds like a bargain – not. Of course, if the concentrated effort and expenditure is made on the MC1R/multiple nevus phenotype, where is the equity for the majority of cases, which do NOT have these risk factors.
I should also like to point our that the Northern Rivers region, which has the highest regional incidence of invasive melanoma in Australia, also has the best mortality to incidence ratios – despite only having one full time dermatologist and the occasional part-timer for a region of 300,000. It is obvious the vast majority of melanomas here are detected in primary care (both traditional GP and skin cancer primary care), and are often managed there, too.
So do we *really* need more machines and more dermatologists to detect and manage skin cancer effectively … ?
If we trained more dermatologists would they move away from the coast? I’m guessing not.
20% of Australians are rural, there’s a massive underspend on that population because of poor access.
How about allow rural patients to claim dermatologist-level rebates when they have a skin check from a doc in their own community; and train those docs to provide a quality service especially in early diagnosis and surgical management.
This business enterprise will hardly make a difference to melanoma death rates.
Getting GPs more involved in skin cancer is definitely the way to go. The less diversion to members of the College of Medicare Item Number Abuse and less referral of low risk/no risk individuals to dermatologists, the more efficient the system will work.
GPs and Skin Cancer College Australasia accredited specialists are the answer, they are already on the job! Dermatologists will take too long to come online and who says these new dermatologists won’t veer off into cosmetic practice? Of course the College of Dermatologists wants more money (and make no mistake, that’s what it’s about for them), but that is not money well spent on serving the skin cancer affected Australian communities.
This article is a nice a PR stunt for a College that limits training positions to family members and those willing to spend years doing unpaid research projects for influential dermatologists. The lack of dermatologists and dermatology services in rural areas is the responsibility of the College who selects its trainees. Their selection process is not transparent nor based on merit nor is there any effort to select trainees likely to practice outside the big cities once qualified.
If the process for internationally trained specialists to practice in Australia would be easier, the problem could be solved very easily. It is the stringent laws against internationally trained specialists to practice in Australia, is why this problem can’t be solved completely.
Good communication between the General Practitioner and Dermatologist is vital. If the referring GP has a patient with a new and changing lesion and the referral is faxed with urgent attention needed or the GP rings the usual wait at my practice is 1-3 days. Not 6 months. I am also intrigued regarding the size of the eventual scar-the guidelines state a 5mm clinical margin for a level 1 melanoma so perhaps the reporting has glossed over some facts. Nevertheless getting a skin check at least every year should be part of everyones routine. “Have you had your skin checked this year?”.
What about opening frontiers to more certified dermatologists from other developed countries comming for work to Australia with equal benefits as local doctors?
In recognition that the majority of primary and secondary skin cancer prevention occurs in Primary Care (by General Practitioners), perhaps this initiative is best achieved as a joint venture with the RACGP and ACRRM?
This is a bit rich coming from the college of dermatologists which has rivalled the ENT and ophthalmic surgeons in operating closed shops with a family connection helping greatly in terms of selection into training. GPs are the answer here.
Great business venture but smells like over-servicing on steroids… even more resources will be wasted looking at harmless lesions on those who are at low risk but who can afford to pay for the scans.
(don’t tell me this won’t happen).
and what about amelanotic melanoma?…
You need more GPs, not more dermatologists! Much cheaper much more accessible much more likely to follow up patients.
I agree with the previous responder, G.Ps are more than capable of detecting a melanoma and any other skin lesion. Also, encouraging the public to be vigilant is more important.
In any event, melanoma and skin cancer are a surgical conditions and should be left to surgeons if it is at all complex.
Training medical students to be as comfortable using a dermatoscope as a stethoscope will make a large difference in melanoma detection, in my humble opinion.
I agree with anonymous – surely it is the role for specialists to educate GPs just like we educate trainees of all levels
Skin Cancer College Australasia has a 3-level education and training program to upskill doctors and nurses in the early detection, diagnosis and management of skin cancer and sun damaged skin. SCCA’s has a strong emphasis on teaching dermoscopy which has been proven to increase diagnostic accuracy for pigmented lesions.
It is important to remember that whilst melanoma is the 4th most common cause of cancer deaths, it accounts for only about 5% of skin cancers. Around a quarter of skin cancer deaths are caused by non melanoma skin cancer.
The sheer volume of disease is such that increasing the number of dermatologists is only part of the answer. This article is unbalanced in this regard in that it fails to recognise the important role of the GP, who is usually the first professional consulted by someone concerned about a skin lesion.
Mathematically, there will never be enough dermatologists and technology will not bridge this gap for many years (for several reasons), during which time many deaths from melanoma will occur. Clearly, the GP workforce is the answer, with second line management via derms.
Upskilling GPs in melanoma detection is a far better use of resources than more specialist dermatologists
