The video above tells you all about skin cancer. The information in this video was correct as of October 1st, 2012.
Skin cancer is the most common cancer in Ireland with over 10,000 new cases diagnosed in 2011. The National Cancer Registry of Ireland (NCRI) expects this number to double by 2040.
Skin cancer is a disease of skin cells. Nine out of every ten cases are caused
by UV rays from the sun or sunbeds. Over exposure to UV rays, which leads to
tanning, redness or burning of the skin, causes damage to skin cells. While
much of this damage is repaired some remains and can lead to skin cancer later
in life. Reduce your risk by following the SunSmart code.
Early detection is also vital. If spotted early up to 90% of cases are curable.
In the case of melanoma skin cancer spotting it early can save your life. For
this reason it is important to get to know your skin, check it every month for
change and speak to your doctor if you are worried.
The skin is the largest organ in the body and is made up of two layers:
Skin cancers are generally named after the cells in the skin where they grow. There are two main groups of skin cancer:
Non-melanoma skin cancers
These are the most common types of skin cancer and include basal cell and squamous cell carcinomas. They tend to grow in areas of the body that have been exposed to the sun and are more common in older people
Melanoma skin cancer
Melanoma is quite rare but greater numbers of people are being diagnosed with it each year. It is also a disease that affects young people. In 2011, of the 887 people in Ireland diagnosed with melanoma 190 were aged between 15 and 44 years.
Melanoma is one of the most serious forms of skin cancer but if spotted early, it is very treatable. If not, it can spread to other parts of the body and cause serious medical issues.
There are six different skin types. They range from white skin that burns and never tans to black skin. In this county three in every four people have skin types 1 or 2 which means their skin burns and does not tan or burns before it tans. This greatly increases their risk of skin cancer. However, even if your skin type is brown or black, which makes it less likely to burn, it can still receive enough UV damage to increase skin cancer risk.
Everyone who spends time outdoors is at risk of skin cancer, not just people who sunbathe. This includes people who work and play outdoors. However there are a few things that increase your risk even more. They include having:
Many skin changes are harmless but if you do have skin cancer spotting it early could save your life. Start by getting to know what is normal for your skin. After that it will be easier to spot change. Aim to check it every month. You could also see your doctor each year for a skin exam.
A normal mole is usually an evenly coloured brown, tan or black spot on your skin. It can be either flat or raised and also round or oval. It is usually less than the size of the top of a pencil.
Moles can be there from birth or can appear during childhood or adolescence. Once a mole appears it will usually stay the same size, shape and colour for many years. It may fade away in older people. Most people have moles and almost all are harmless. But it is important to spot changes in a mole. These changes could be a sign the mole is becoming a melanoma.
Skin cancers do not all look the same. They can appear in a number of ways including any of the following:
Non-melanoma often appears as one of the following:
Melanoma mainly develops from a new mole or a change to an existing mole. The changes to watch out in existing moles are:
As not all melanomas develop from moles it is important to speak to your doctor if you spot other skin changes that are unusual for you.
If you have difficulty checking your skin you could ask your doctor or a friend to check those hard to see places. You could also use two mirrors to check your entire body.
Check yourself regularly - remember, early detection and treatment offers an excellent chance of a cure.
Here are five steps to examine your skin yourself.
