My mum has palliative lung cancer and over the past few days a golf ball size lump appeared. I managed to get an apt atbthe breast clinic as she was under their care for a separate issue and had a coincidental apt lined up which I brought forward. They've completed a biopsy ultrasound and believe on balance but subject to biopsy, this is from the lung cancer. I understand this is relatively rare as a process of metastasis, for lung cancer to spread to breast.
My question is what is likely to happen next once confirmed it is lung related? It appears there are very limited low impact treatment options and she's already had palliative radio therapy which impacted her greatly, so this won't likely be an option for her.
Can they operate? What side effects could this cause? Do more normally appear?
Thanks in advance.
