Hi, I’m new here. I was diagnosed with ER+ and HER 2+ breast cancer in 2021. I had surgery, chemotherapy, radiotherapy and an injection for a year afterwards. I have had a slow recovery with issues in my shoulder, arm,  breast, back (other side of breast) which I believe to be a result of radiotherapy. I’ve had ongoing issues trying to fully raise my right arm which is painful. Thankfully had a clear mri and ct last year which is the best news. 

I have recently found a small lump in the middle of the palm of my hand. I’m sure anyone who’s been through cancer treatment and finding another lump of any size sends your mind racing. This may be nothing at all but should I be getting this checked out or am I just overthinking it? 

thanks for taking the time to read this
