Drinking alcohol increases a person’s risk of developing non-melanoma skin cancer, according to a review published in British Journal of Dermatology.
Previously, the association between alcohol intake and non-melanoma skin cancer – which mainly comprises of basal cell carcinoma and cutaneous squamous cell carcinoma – was inconclusive. Therefore, the objective of the recent review was to quantify the relationship between alcohol intake and non-melanoma skin cancer using meta-analysis.
A systematic review was performed on 13 case-control and cohort studies that looked at alcohol intake and risk of non-melanoma skin cancer. The studies included 91,942 basal cell carcinoma cases and 3,299 cutaneous squamous cell carcinoma cases.
The review found that for every 10-gram increase in ethanol intake per day, there was a positive association for both basal cell carcinoma and cutaneous squamous cell carcinoma. It concluded that drinking alcohol increases non-melanoma skin cancer risk in a dose-dependent manner.
The review proposed that the results could serve as an important public health target to reduce the global health burden of non-melanoma skin cancer, as alcohol drinking is a prevalent and modifiable behaviour.

We know that dermoscopy provides us with more information than is possible with the naked eye. The trick is to understand what the additional information means, and what we should do with it! This is where research on dermoscopy and management guidelines is so important. In this case, we are particularly looking at the management of Spitz nevi.

A ‘groundbreaking’ immunotherapy drug is helping patients overcome advanced non-melanoma skin cancer.
Cemiplimab is being used at Sir Charles Gaidner Hospital in Perth as part of an international trial. Oncologist Annette Lim, who runs the trial, says most patients have responded with encouraging results.
There were strict criteria for patients to enter the trial, but early results suggest the drug could be a game-changer for non-melanoma skin cancer sufferers. Continue reading “Groundbreaking Immunotherapy Drug Beats Skin Cancer”
A new research centre in Brisbane will test a variety of products that claim to be sun safe.
Queensland University of Technology (QUT) is partnering with Q-Pharm to open its Centre for Testing New Technology, which will test lotions, apps, patches and wearables, and any other products that promise to protect users from the sun. Continue reading “Sun Safe Devices Put To The Test”
Merkel cell carcinoma (MCC) is a rare, aggressive, and often fatal neuroendocrine skin cancer – the incidence of which has increased in recent decades. Early and recurrent MCC is managed very differently than other skin cancers.
People at higher risk of developing Merkel cell carcinoma are typically those who have had multiple prior skin cancers and those who are immune suppressed, such as organ transplant recipients. Continue reading “Managing Merkel Cell Carcinoma”
The US Food and Drug Administration has approved Novartis’ Tafinlar-Mekinist combination for use as a stage 3 melanoma treatment, just four months after the drug was approved for treatment of non-small cell lung cancer with a BRAF V600E mutation.
The BRAF/MEK combination can now be used to treat this particular mutation after studies found that the drug halved patients’ risk of death or melanoma recurrence compared to placebo, in a phase 3 study completed in September. Continue reading “Stage 3 Melanoma Treatment Approved”
This week, we have another wonderful case from Dr Slavko Doslo. A 77-year-old male presented for a skin check and a lesion was noticed as indicated.

Canberra residents with serious skin problems, including people with melanoma, are being forced to travel to New South Wales to see dermatologists due to a shortage of specialists and lengthy waiting times in the nation’s capital.
The Australasian College of Dermatologists reports that GPs in Canberra are not referring their patients to local dermatologists because patients could be waiting up to six months for specialist treatment.
There are six dermatologists working in the Australian Capital Territory – half the number necessary to support the region’s population, the College reports. Continue reading “Lack of Canberra Dermatologists Forces Melanoma Patients To Travel Interstate”
One of the greatest hurdles in our fight against cancer can be our own immune system, as it often self-sabotages the body’s attempts to fight invading tumours. Researchers from the University of Bonn have recently found a way to get around this immune response, using immunotherapy to achieve a significant delay in cancer growth, which thereby allows cancer sufferers to live longer as the progression of their disease is slowed down.
