There's no way for anyone to know for sure if you will or won't get skin cancer. I'm assuming you're white, so your chances of getting basal cell cancer is around 30%. Squamous cell carcinoma is about 4 times less likely, or just under 8%. That may seem like a high statistic, but basal and squamous cell cancers are extremely curable, since they rarely metastasize. Melanoma, on the other hand, is much more sinister. Still, your chances of getting melanoma are under 2%, and if you tan easily and tend not to burn or freckle, your chances are significantly lower. They're lower still if you don't have a family history of melanoma or have darker hair and eyes. This is true for all skin cancers, actually.
Even if you did get melanoma though, the overall 5-year survival rate is close to 90%. This is because melanoma's tend to be nasty looking, clearly distinguishable from benign moles, even at early stages, so only surgery is usually needed. Nodular melanomas are more aggressive and tend to look more benign though (though they're rare, especially in women), so it's always important to be vigilant and look for any changes in your moles or new ones that pop up. It wouldn't be a bad idea to have a regular dermatologist and get checked up at least once a year.
I wouldn't worry though, if you tan that easily and don't burn, although it is always better to be safe than sorry.
