Foot melanoma is one of the rarest forms of skin cancer, but it's also one of the most dangerous. Because many people forget about feet when checking for and protecting against skin cancer, foot melanoma tends to go unnoticed until it's at its advanced stages. Thankfully, with some careful precautions, you can reduce your risk of developing serious skin cancer on your feet. Here are three tips to follow.

Avoid Wearing Sandals

Without a doubt, sandals are the most popular type of footwear for summer. Whether you're on the beach or travelling about town, sandals are likely one of your go-tos when the weather heats up. However, while they may be stylish and comfortable, they also increase your risk of skin cancer because they expose your feet to the sun's harmful rays. It's far better to wear enclosed shoes when the sun is out, but that doesn't mean you have to be uncomfortable. Look for breathable shoes that prevent your feet from getting sweaty; one of the best choices is stylish trainers made for runners and athletes.

Apply Sunscreen to Your Whole Foot

Of course, there will be times when you'll want to go barefoot—when you're on the beach or at the pool, for example. When you do, remember to apply sunscreen to your entire foot. Too many people stop when they reach the ankle, leading to harmful sun exposure that can cause skin cancer. Besides applying the scream or spray to the top of your foot, don't forget the bottom. The tender soles of your feet can burn quickly, and they get a lot of sun exposure when you're sunbathing or lounging. Of course, as with the rest of your body, remember to apply every few hours or more often if you've taken a dip in the pool.

Check Your Feet for Melanoma

As with all types of skin cancer, one of the best ways you can avoid a life-threatening case is to regularly check your skin for signs of melanoma. The same goes for the skin on your feet. When you're washing your feet in the bath or applying a pedicure, take a few minutes to check them for skin cancer symptoms. If you see a lesion and you're not sure whether to be concerned, a helpful acronym to remember is CUBED:

• C is for Colour: Is the lesion a different colour to your skin?
• U is for Uncertain: Are you unsure of what the lesion could be caused by?
• B is for Bleeding: Has the lesion been bleeding or leaking any other fluids?
• E is for Enlargement: Is the lesion growing over time?
• D is for Delay: Is the lesion taking an unusually long time to heal?

Make sure you check your whole foot, including your soles and under your nails. If you do find something that concerns you, head to a skin cancer clinic for a diagnosis.
