Sorry for all you’ve been through and the unnecessary added pain issue. I had years of excruciating pains from keloid scars post-mastectomy that shouldn’t have happened. Long story. I have CHEK2 and BRCA2 mutations. Breast cancer and neuroendocrine lung cancer. Lung issues are unrelated to the mutations at least based on today’s science. Tomorrow’s science may tell a different story.

BTW, I had cysts on my ovaries for decades due to polycystic ovary syndrome. Ovaries gone now. PCOS causes metabolic issues but the cysts were never cancerous. Hopefully your cyst is something more benign like that.

I know how you feel though. Once you have cancer, every new pain, cyst or anything makes you wonder.
