I was using enbrel for about 3 years. My doctor discontinued the use of the injections around November of 2015. But I've since been diagnosed with 2 kinds of cancers.uterine cancer. And now early breast cancer.and there is no history of breast cancer on neither my mom or my dads side of the family. So I'm wondering if my use of enbrel caused these cancers along with the fungal infections. I was prescribed enbrel because of rheumatoid arthritis. And now I'm on orencia.
