Although our SunSmart Campaign runs from December to January, CANSA reminds all South Africans to be SunSmart throughout the year and especially during Summer.
Skin cancer is the most common cancer worldwide and SA has one of the highest monitored ultra violet (UV) levels in the world, resulting in one of the highest skin cancer rates globally.
It’s getting hotter, so be SunSmarter and let’s throw shade at skin cancer this summer!

Skin Cancer Common in SA
South Africa has the 2nd highest incidence of skin cancer in the world after Australia, and in particular one of the highest incidences of melanoma worldwide, as far as Caucasians are concerned.
At least 20 000 South Africans are diagnosed annually with non-melanoma skin cancers, and a approximately 1 500 are diagnosed with melanoma.
It is important to take note of the fact that everyone, regardless of racial or ethnic group, is at risk of getting skin cancer. Although people with darker skins are less susceptible, because their skin contains more natural melanin, that protects against sun damage, everyone is at risk from the harsh African sun.
According to the World Health Organisation (WHO), the incidence of both non-melanoma and melanoma skin cancers has been increasing over the past decades, and WHO estimates that a 10 % decrease in ozone levels will result in an additional 300 000 non-melanoma and 4 500 melanoma skin cancer cases globally.
Types Skin Cancer
There are two main categories of skin cancer, namely, melanoma and non-melanoma.
Melanoma (NCR 2013), is less common than other skin cancers, but it is the most dangerous. It is of special importance to note that excessive ultraviolet (UV) radiation received as a child, increases the risk of melanoma later in life. Melanoma is linked with short, sharp bursts of over-exposure, so even one incident of bad sunburn, especially in childhood, can later on in life, trigger damage and develop into a melanoma.
The newly crowned Mrs South Africa, Nicole Capper, a skin cancer Survivor says, “As a cancer Survivor sun protection is a massive focus for me. Being diagnosed with malignant melanoma at 25 rocked my world, but I was lucky to have caught it early enough. We’re so aware of other potential health concerns and we make sure we visit specialists annually for other standard check-ups, and yet our skin is neglected for the most part, often until it’s too late. Sunscreen is always healthy. And regular dermatologist appointments should be mandatory. We owe it to our families and communities to stay healthy, and our skin is no exception.”
Non-melanoma skin cancers mainly comprise Basal Cell Carcinoma (NCR 2013) and Squamous Cell Carcinoma (NCR 2013). Of these, Basal Cell Carcinoma is the most common and the least dangerous. These cancers are linked to long term exposure to the sun, for example people with professional sports careers or outside occupations. If left untreated, these can lead to disfigurement, or the loss of an eye, nose or ear, so early detection is important.
Squamous Cell Carcinoma (SCC) is most frequently seen on sun-exposed areas of the body such as the head, neck and back of the hands. Although women frequently get SCC on their lower legs, it is possible to get SCC on any part of the body, including the inside of the mouth, lips and genitals. People who use tanning beds have a much higher risk of getting SCC – they also tend to get SCC earlier in life.
People with Darker Skin also at Risk
Although people with darker skins are at a lower risk of melanoma than lighter skinned groups, the majority of basal cell carcinomas, in people with darker skins, occur in sun-exposed skin, indicating that sun protection is paramount, regardless of pigment. ¹
In darker skins, 70 % of melanomas have been reported to be on the lower limb, with 90% of those being below the ankle. The most common subtype, acral lentiginous melanoma, appears on the palms of the hands and soles of the feet. ²
Nikki Seboni believed that skin cancer was a white person’s disease, until she was diagnosed at the age of 25 years. Read more…

Other skin cancers include:
The following conditions can give rise to cancer or be mistaken as cancer:
- Spitz Naevi (usually present in toddlers and children), can mistakenly be thought to be Malignant Melanoma because of the close resemblance…
- Actinic Cheilitis and Actinic Keratosis – are pre-cancerous conditions that can lead to Squamous Cell Carcinoma
- Bowen’s Disease – is a pre-cancerous condition that can lead to Squamous Cell Carcinoma
- Balanitis Xerotica Obliterans (BXO) – is a pre-cancerous condition that can lead to Squamous Cell Carcinoma
- Gorlin-Goltz Syndrome, is an inherited medical condition involving defects within multiple body systems such as the skin, nervous system, eyes, endocrine system, and bones. People with this syndrome are particularly prone to developing a common form of non-melanoma skin cancer.
- Solar Elastosis – is a pre-cursor to Squamous Cell Carcinoma
- Xeroderma Pigmentosum (XP) – an inherited condition characterised by an extreme sensitivity to ultraviolet (UV) rays from sunlight. Most people with XP develop multiple skin cancers during their lifetime.
- The sun is only dangerous in summer or on a hot day
- Sunscreen will protect me completely from the harmful effects of the sun’s rays
- One or two cases of sunburn won’t result in skin cancer

The Truth About Tanning
There is no such thing as a healthy tan – even a sunless tan…
In recent years there has been a considerable increase in the use of sunless and self-tanning products such as sprays, mousses, gels, pills, nasal sprays & injections called Melanotan 1 and 11.
Melanotan 11 has serious side effects, and may induce melanoma. CANSA warns against this product. Read our Warning Against Melanotan-II…
Sunless tanning, also known as UV-free tanning, self-tanning, spray-tanning (when something is applied topically) or fake-tanning – refers to the application of chemicals to the skin or making use of chemicals that are taken by mouth or per injection, to produce an effect similar in appearance to a suntan. The browning effect usually occurs within a few hours. The effect is temporary – the colour fades in 7-10 days as the skin naturally sloughs off.
Sunless tanning products include:
- Bronzing powder
- Spray bronzers
- Stick bronzers
- Tanning wipes
- Tanning tablets
- Tanning capsules
- Tanning injections
- Tanning nasal spray
- Sunless tanning lotion
None of these is safe!
- Although some self-tanning products contain sunscreen, it offers minimal ultraviolet radiation protection. It does not provide protection from the ultraviolet rays of the sun and CANSA strongly discourages individuals to use any form of tanning product.
- Topical sunless tanning products that contain Dihydroxyacetone (DHA), prevent the formation of Vitamin D in the skin when exposed to the sun.
How to Lower your Skin Cancer Risk:
1. Do a Monthly “Spot the Spot” Check Up:
Always seek medical advice as soon as possible when concerned about a particular spot on your skin. Check your skin carefully every month and ask a family member or friend to examine your back and the top of your head. If you notice any of these warning signs, see a doctor or dermatologist immediately – follow the A B C D E Warning Signs:
2. Get Screened at Your Local CANSA Care Centre
- Go to your local CANSA Care Centre for screening with our FotoFinder Dermoscope machine – be sure to make an appointment as the machines ‘roam’ between Care Centres.
- If you are concerned re symptoms, please do not wait – contact your Care Centre, doctor or dermatologist immediately.
- Monitor the harmful UV-rays you are exposed to with a CANSA UV-Smart Armband that turns darker in colour as the UV-rays intensify. Each shade of colour gives protection recommendations you can follow in order to avoid sunburn.
3. Avoid the Following
- Stay out of the sun between 10am and 3pm – stay under the shade of trees or an umbrella as much as possible
- Avoid sunbeds & sunlamps
Tips: Sunscreen & Protective Garments
1. Use an Effective Sunscreen
- We have raised our Seal of Recognition standards & requirements for sunscreens. In addition to current SA standards, as of 1 April 2013, sunscreens bearing our Seal need to comply with the European Colipa Standards.
- Our new CANSA Seal of Recognition logo (CSOR) appears on approved sunscreen products and is a guarantee that the manufacturers of these UV protective products have complied with CANSA’s strict set of criteria – see new logo to the right.
- See list of CANSA’s SunSmart Sunscreen Partners…
- Be sure to use a sunscreen with an SPF of between 20 and 50 & 30 and 50 for fair to very fair skin.
- Products usually expire two years after manufacture – don’t use a product that has been opened and used after a year has passed.
2. Apply Sunscreen Correctly
- It’s important to know the best SPF for your skin-type
- Always apply sunscreen 20 minutes before you go outside and re-apply at least every two hours, after towel drying, perspiring or swimming.
3. Wear Protective Clothing
- Wear sunglasses with a UV protection rating of UV400
- Wear protective clothing & swimsuits and thickly-woven fabric hats with wide brims – avoid caps where the neck & ears are exposed
- Buy SunSmart garments & apparel… – look out for CANSA’s swing tags (right) & SunSmart Choice logo (top right) on clothing, hats & summer fun accessories.
Educate & Protect Children
Our youth should take special precaution when spending time in the sun – two blistering burns before the age of 18, can dramatically increase the risk of getting skin cancer later in life.
Parents and schools need to play an increasingly important role in educating our youth re being SunSmart. Unfortunately a recent study shows that most schools are not SunSmart. Read more…
Babies younger than 1 year should never be exposed to direct sunlight.
