Swelling after radiotherapy

Hi I'm 8 weeks post radiotherapy and experiencing  swelling.

I had a bilateral  lumpectomy  and a full axillary  node clearance where  19 nodes  were removed to help prevent  reoccurrence and  2 were removed.

I also have stabbing pains  but not so worried  about these as I know  it's a sign of healing.

I have the Brca 1 gene and constantly  worried as my surgeon refused to do a bilateral  masectomy  and reconstruction and has since told me there is a long waiting list and as it's just insurance  surgery  it can wait but I'm living in fear daily  and also awaiting  an Oophorectomy.

Hopefully  the swelling will subside soon.

My oncologist  saw it was swollen  around a week ago but wasn't  concerned.
