Former Bachelorette star Ali Fedotowsky revealed Thursday on Instagram that she's been diagnosed with basal cell carcinoma, a common form of skin cancer.Us Weekly reports that Fedotowsky captioned her post, "GET YOUR SKIN CHECKED,” before giving details about her condition. “A couple of weeks ago, I found out I have skin cancer. When my dermatologist used the c-word, I just about fainted in his office. Thankfully, the type of skin cancer [that] I have is rarely fatal and really never fatal when you catch it early … Needless to say, I’m never exposing my stomach to sun without sunscreen again!” The 2010 Bachelorettere assured fans that the carcinoma is "super common" and highly treatable. “But what IS a big deal is not treating it and treating it early … The VERY first thing I did when I got diagnosed was text my family on a group text urging them all to get their skin checked. So I’m doing the same for all of you, my extended family, right here and right now,” she wrote.
