Understanding Skin Cancer
Skin cancer happens when skin cells start to grow the wrong way. You may see something unusual, such as an odd-shaped lump or a change in a mole. We call this a lesion.
There are three main types of skin cancer:
- Basal cell carcinoma - this is the most common type. It grows slowly and rarely spreads. It is normally easy to treat.
- Squamous cell carcinoma - this can grow fast and may spread if not treated quickly. If caught early, it is often curable.
- Melanoma - less common but the most serious type. It can spread quickly so it is important we catch this early.
There are other pre-cancerous conditions that can lead to skin cancers. ‘Pre-cancerous’ means it is not yet cancer, but cells have started to change. If we do nothing, cancer could develop. If we diagnose and treat pre-cancerous conditions early, this could stop cancer from developing.
Sometimes we need to do a biopsy. This means we take a small tissue sample and send this to a lab. Specialists then check the sample under a microscope
Some rarer types of skin cancers need a biopsy and have their own treatments. If you are diagnosed with a rare skin cancer we will tell you about these treatments.
Most skin cancers are caused by ultraviolet (UV) light from sunlight or sunbeds.
There are simple ways to protect your skin:
- use SPF 30+ and reapply often (if you are on a sunny holiday, do this at least every 2-3 hours)
- stay in the shade between 11am-3pm
- wear sunglasses, sleeves, and a hat
- check the UV index — if it’s 3 or above, cover up!
