So some of you have been concerned about skin cancers so I thought I would make a quick video using some pictures, on how you may identify some of the early stages of skin cancer. I must reiterate however, that a diagnosis can only be made through a biopsy and I always recommend to see your family doctor with any suspicious looking skin problem.

BCC

Features:
• Slowly growing plaque or nodule
• Skin coloured, pink or pigmented as you can see from this pic
• Varies in size from a few millimetres to several centimetres in diameter
• It can bleed spontaneously and ulceration may occur
• Some of these may have tiny blood vessels across their surface called telangiectasia as you might be able to see here from this picture and this picture

Squamous CC

Features
- They tend to grow over weeks to months
- They may ulcerate
- They are often tender or painful
- Located on sun-exposed sites, particularly the face, lips, ears, hands, forearms and lower legs. This Particular SCC is located on the ear and it looks like its ulcerated. Interestingly it does seem to have a rolled up edge like what you’d find in a BCC so its important to have all suspicious lesions checked out by your GP.
- Size varies from a few millimetres to several centimetres in diameter. And I’ll just give you sometime to have a look at a few others.
Other Skin cancers
Other types of Squamous CC which may spread include:
- Cutaneous horn
- Keratoacanthoma
- Carcinoma cuniculatum (‘verrucous carcinoma’).
- Actinic Keratosis -
- Multiple SCC from genetic conditions such as in this pic as multiple nodules occurring on the hands of this person.
- Basosquamous Carcinoma

Melanoma

The most serious type of skin cancer due to uncontrolled growth of the pigment cells inside the skin and these can occur anywhere on the body and not just the sun exposed sites and this is what one may look like.
This is more common with increasing age, in those with fair skin, in those patients that have many moles on their body, in those with a strong family history of melanoma.

Melanomas can arise from otherwise normal-appearing skin (this occurs in about 75% cases of melanomas) or from within a mole or freckle, which starts to grow larger and change in appearance. These are called pre-cursor lesions.

The first sign of a melanoma is usually an unusual looking freckle or mole. Melanoma may be detected at an early stage when it is only a few millimetres in diameter, but it may grow to several centimetres in diameter before it is diagnosed.

ABCDE criteria
ABCDE criteria for suspected melanomas– Asymmetry, Border, Colour, Diameter and Evolving
Prevention
 Stay indoors or under the shade in the middle of the day
 Wear covering clothing
 Apply high protection factor SPF50+ broad-spectrum sunscreens generously to exposed skin if outdoors
 Avoid indoor tanning (sun beds, solaria)
 Oral nicotinamide (vitamin B3) in a dose of 500 mg twice daily may reduce the number and severity of SCCs in people at high risk.
