Sunscreen protects from skin cancer, burning and from the sun’s ageing effects.

Whenever summer rolls around, it's easy to forget the basics of sunscreen. How long should I wait after applying it to go in the sun, and how long can I stay in the sun with it on?
Applications to list drugs on the PBS are usually submitted by the manufacturers of those drugs.
Some argue the current system of subsidising drugs in Australia needs changing to accommodate new cancer therapies. But two recent drug listings show the current system is working perfectly well.

Doctors are taught how to treat skin cancer – but not necessarily how to empathise with those who have it.

Melanoma, the deadliest form of skin cancer, can usually be cured when caught early. When it has spread, however, it becomes a challenge. Recent findings are bringing hope. Here are a few examples.
Machines don’t make the same errors as humans when it comes to decisions based on visual analysis.
The value of machine learning is not only that it is more accurate than humans. It is also cheaper and more consistent in its diagnoses.
Lumps and bumps of all kinds crop up on our skin as we age, but how can you tell which ones you don’t need to worry about?
Most of the skin lumps we develop will be benign. Here are some of the most common, and how to tell them apart.
Where’s it gone?
A few cancers vanish without any medical treatment. Researchers are studying these 'spontaneous regressions' to see if they can lead to new cancer treatments.
A mobile phone is not a medical device – so don’t believe apps that say they are.
With an estimated 100,000 health and fitness apps available, it seems there is an app for everything – from tracking your bowel movements to practising your pimple-popping technique.
Although skin cancer is preventable, South Africa still spends millions on treatment.
Skin cancer – which is preventable – costs the South African health system more than is necessary.
People who have many moles on their body – as well as those with atypical moles – have a predisposition to melanoma.
A recent study claims most people with melanoma don't have many moles or any atypical moles. But exploring the study in depth shows these conclusions don't have a strong foundation.
International Agency for Research on Cancer has classified UV-emitting tanning devices as a Group I carcinogen – the most dangerous cancer-causing substances.

Researchers have estimated that 8% of the five million cases of skin cancer diagnosed each year in the US can be attributed to indoor tanning.
Keytruda® targets a protein on the surface of immune cells that stopped them from attacking the melanoma cells.
Keytruda® is the latest drug to be registered in Australia for the treatment of widespread melanoma. But we must wait to see if it meets the cost-effectiveness targets for PBS subsidisation.
Sun exposure that doesn’t result in burning may still damage the skin cells.
Around 30 Australians are diagnosed with melanoma every day and more than 1,200 die from the disease each year. While small amounts of ultraviolet (UV) radiation are required for the production of vitamin…
If you’re at high risk of skin cancer, check your skin regularly.
The earlier you find a cancerous mole, the easier the treatment and the better the outcomes. But it’s not easy distinguishing between harmless, benign moles and those that warrant further attention. In…
The prevalence of itches and pain in patients with skin cancer can help clinicians identify which of these cancers are melanoma…
Growth states of cancer cells can now be visualised in real time, thanks to a new 3D model of a melanoma tumour developed…
The way melanoma cells manage tangled DNA could explain why they rapidly develop resistance to cancer treatment. Researchers…
Skin colour doesn’t just affect your tanning ability.
Europeans fall prey to skin cancer because of their lighter skin, while Africans’ dark skin protects them. But East Asians, whose skin colour resembles that of Europeans, are similar to Africans in their…
A gene mutation responsible for red hair and pale skin is also attributed to risk of melanoma. An international study found…
The humble fruit fly: teaching us more about melanoma skin cancer.
Melanomas may be less common than other skin cancers but their ability to become malignant and spread to other parts of the…
