I was diagnosed with breast cancer in November 2014. After having a lumpectomy and radiation treatment, I felt that I have made a good recovery. However, since my cancer was oestrogen sensitive, I take a daily dose of Letrozole to supress this hormone. Over the past year my joints tend to feel stiff and painful, despite the fact that I try to exercise regularly. Added to this, I am having lots of trouble with my teeth. I've had abcesses and eventually need to have two teeth extracted. Over the Easter period I had an ear infection which led to cellulitus on the right side of my face. I feel that I seem to be very susceptible to infection of late. Is this a common feature for patients with similar conditions?
