Artificial intelligence has the capacity to revolutionise skin cancer medicine, with multiple programs in development that aid in the early detection of the disease. One such program is Doctor Hazel – a platform that could someday identify cancerous moles with a success rate of 90 percent, provided it attracts enough user submissions.
Still in its infancy, Doctor Hazel was demonstrated earlier this week by a team of engineers at TechCrunch’s Disrupt San Francisco 2017 hackathon. The artificial intelligence program currently identifies cancer at an 85 percent success rate; however, the team has launched a beta and is inviting users to submit their own photos to improve the platform’s performance.
In this skin cancer update video, Associate Professor Giuseppe Argenziano shares the results of a meta-analysis of nevus-associated melanoma. The study asked whether a nevus was a precursor lesion of melanoma.
It found that only a third of melanomas arise from a pre-existing nevus, and the majority of melanomas developed from nondysplastic nevi.
If you perform skin cancer surgery in your practice, you might be interested to see the 1-minute video below with experienced skin cancer doctor Hamilton Ayres. Dr Ayres uses the principle of hydrodissection to remove a lesion on a patient’s ear. The injected fluid helps to separate the tissue planes and facilitates excision.

This week we have another engaging case discussion from Dr Slavko Doslo. A 76-year-old patient presented for ROS.
What do you think of this clinical image? What is your impression? (Ignore the adjacent scar).
Skin Cancer Summit & Masterclasses
The 9th Skin Cancer Summit and Masterclasses saw international thought leaders in skin cancer medicine converge in Brisbane to collaborate with GPs from across Australia.
Researchers at the Queensland University of Technology (QUT) and University of Queensland (UQ) are currently undertaking research examining mobile teledermoscopy. The researchers are interested in your opinions about imaging devices and systems used for photographing potential skin cancers, in particular, pigmented lesions that might be suspicious of melanoma. Mobile teledermoscopy could be used for referral, documentation, telediagnosis, discussing the lesion with colleagues, or to obtain a second opinion.
This week’s case discussion is about an elderly man presenting with a cough. On examination, both a basal cell carcinoma and the pigmented lesion shown here were noted.
What is your assessment? Is there anything to be concerned about? Continue reading “Case discussion: How would you treat this patient? [24 July]”
Data shows that adding afatinib to standard chemoradiation therapy does not improve disease-free survival among patients with squamous cell carcinoma of the head and neck.
Researchers from the Yale Cancer Centre have presented the findings of a randomised, double-blind, placebo-controlled, phase three trial of afatinib as adjuvant therapy after chemoradiation in primary unresected, high- or intermediate-risk, squamous cell cancer of the head and neck patients.
A breakthrough has been made in the early detection of melanoma, using a compound called fluorinated benzamine. The development could lead to a much faster and more accurate diagnosis of melanoma.
Melanomas can start out as a blemish or mole and often aren’t taken seriously until cancer cells have spread and it’s too late. The fatal disease is difficult to detect as it often grows under the skin before lesions appear suspicious. Continue reading “Research into Faster and More Accurate Detection of Melanoma”
Researchers have pinpointed a sugar modification in cells that spurs the spread of skin cancer. The study reveals that FUT8 – an enzyme that transfers the sugar fucose onto proteins – is a driver of melanoma growth. When silenced, it suppresses the onset of cancer and the dissemination of tumours in laboratory mice.
Scientists have long thought that the process in which carbohydrates attach to cells – known as glycosylation – plays an important role in the progression of melanoma; however, no comprehensive analyses of clinical samples exist to support this assertion.
