11 Signs It's Skin Cancer

© Shutterstock Fact: Skin cancer is the most common form of cancer in the U.S. Fact #2: Most people don't know how to apply SPF properly. Also a fact (and a bummer): Deadly skin cancers will continue to increase over the next 15 years. Basically, the sun + your skin = a really bad combination if you're not careful.

Now that we've thoroughly horrified you - sorry, not sorry - how about some cheering up? The good news is that the earlier you catch and treat it, the more likely your dermatologist can cure cancer - about 90 percent of the time, says Yale dermatologist, Mona Gohara, M.D. Small win! But before you roll your eyes and protest that you never use tanning beds or spend *that* much time outside, over-exposure to UV rays isn't the only factor you need to consider.

Here's a sampling of things that you'd be surprised increase your cancer risk:

  • Having a family member with a history of skin cancer increases your odds.
  • Fair skin - especially if you have blond or red hair.
  • Getting many X-ray treatments (this can take many years before it poses a significant risk, but the more you know...).
  • Having an immune-weakening disease such as Lymphoma and HIV.
  • Bad burns or scars that have been exposed to UV rays.
  • Smoking cigarettes. (Why are we not surprised?)

So, now you know what can cause this fatal disease, how do you spot it? First, we need to break skin cancer into its three basic types: basal cell carcinoma (BCC), melanoma, and squamous cell carcinoma (SCC).

BCC is the most common form of skin cancer and is often located in areas frequently exposed to sunlight (neck, face, hands, arms). Melanoma primarily refers to moles and it's the deadliest form of skin cancer. SCC is similar to BCC except it also includes cancer found specifically inside the mouth, on the lips, and around a person's genitals; it also usually stems from pre-existing conditions (like diseases or genetics). (*Pauses for you to absorb all that.*) We good?

A lot of their symptoms overlap - which doesn't *really* matter because despite which category you fall under, it's still skin cancer. We tapped into Gohara's expertise to find out which "little" signs could potentially mean big trouble down the road if untested: 

1. Unevenly sized moles.

If you cut it in half, do both sides match up? Asymmetrical moles aren't good.

2. Moles with jagged or irregular edges.

Normal ones are typically smooth.

3. Moles that become darker or just change color.

4. Moles that grow in size.

Anything bigger than, say, the size of a pencil eraser needs to be checked out.

5. Moles that bleed or hurt.

6. Pimples that won't go away on sun-exposed skin.

Zits appear and disappear all the time, but if a translucent, pimple-like bump doesn't go away after a month or so, it's most likely not a pimple.

7. Bruises on your feet that won't heal.

8. Exposure to HPV.

This one took us by surprise. Genitals - that normally don't see daylight unless, you know, you're chilling at a nude beach - with the virus can also develop squamous cells and lead to skin cancer.

9. A "non-healing sore."

This often refers to problems in the mouth (caused by smoking). Oral skin cancer falls under the SCC column, so please, DON'T PUFF THE TOBACCO.

10. Brown or black streaks under your fingernails.

These can also appear on your toes.

11. Crusty, scaly skin.

But there's a big difference between skin cancer and unrelated conditions like dry skin, psoriasis, or eczema even though these can all appear similar. Usually, areas affected by skin cancer are tender and won't respond to topical creams that most other ailments react to.

While these symptoms don't always 100 percent signify that you have skin cancer, you should schedule an appointment with a dermatologist juuuust to be sure.
