How To Identify The 3 Types Of Skin Cancer
This Videojug video explains two major types of skin cancers. Most common skin cancers are easy to treat. But the aggressive skin cancer types are very persistent and these are seen occurring widely in younger age groups. The video also goes about explaining the symptoms to identify the cancer type. The aggressive, malignant skin cancers arise from moles and there are five rules to determine whether these moles are serious or not. Earlier detection and prevention is the best key in fighting cancers.
Hi, my name is Dr. Ranj Singh and I'm an NHS doctor and a media medic. I'm going to take you through a series of common medical questions that people often ask me.
Okay so in this video were going to talk about how to identify the three most common types of skin cancer. Now skin cancers can generally be divided into two groups. And that's the No melanoma types and the melanoma types.
In the non melanoma group, we have basal cell carcinomas which make about 80% of skin cancers and we have squamous cell carcinomas and those make up about 10%. In the melanoma group, we have what we call malignant melanomas and they make up the other 10% of skin cancers. Now fortunately the nonmelanoma types that's the basal cell carcinoma and the squamous cell carcinoma are more common but they are lot easy to treat and they are a lot less aggressive.
Malignant melanoma, on the other hand is potentially a lot more serious and unfortunately greats of malignant melanoma are rising particularly in younger age groups. By far the biggest risk factor for developing skin cancer is sun exposure and be that from direct sunlight or through the use of sun beds.
Now early recognition and prompt treatment of skin cancers is essential and were going to talk about how each one might present.
Now basal cell carcinomas, first of all, these can either develop as a ??, waxy white lump or as a flat scaly skin patch. And these patches can actually grow to quite large, they can grow to 10-15 centimetres and characteristically they do not heal. Now these tend to develop on sun-exposed areas for example on the face, on the ears, on the neck, up the chest and the arms.
Squamous cell carcinomas start off as firm red lumps and again these can appear in sun-exposed areas such as the arms or the neck or the face but can also develop in other areas such as the genitals, and the anal region as well.
Now the third type is malignant melanoma which can develop from either in existing mole or a new mole altogether. Now fortunately there is a very clear cut rule that you can use to identify whether a mole is potentially serious and that's what we call the ABCDE guide, and were going to go through that one by one.
So first of all, A stands for asymmetry. Normal moles tend to be symmetrical and one colour throughout whereas malignant melanoma tends to have two halves to it or can be varied in appearance.
B is for border.
Malignant melanomas tend to have a very irregular or a straggly border and that can point you in the right direction that it may not be something as benign as a mole.
C is for colour. Now serious moulds tend to be vary?? in colour, they can be made up of more than one colour and often are a combination.
D is for diameter, now malignant melanomas tend to be over six millimetres or a quarter of an inch in size.
And E is for elevation. Moles that are serious can be raised away up from the skin, so that may appear as more of a bump than just a flat mole.
Now always remember, that if you have a new skin spot or a mole that's developed and you're worried about it then you must seek help. If you've got a new skin lesion that doesn't heal after two weeks in particular, make sure you go and see your doctor to find out whether it is one of these potentially serious conditions. So to be honest prevention is the key, so make sure you watch your sun behaviour and protect yourself by using sun block.
And that's how you identify the three different types of skin cancer. .
