I was diagnosed in 2013 with DCIS high grade 3, HER Positive +++ I undertook a mastectomy same year (close margins), and was prescribed tamoxifen but after 5 months was discontinued due to painful side effects.

Have recently discovered a hard lump (not painful) just under mastectomy scar November 2025. Anyone else experienced this? Also I have had a persistent cough for the past 6+ months and feeling so tired even after doing small chores.

Saw breast consultant last Friday 28/11/25 unfortunately there was no qualified radiologist to perform a scan or biopsy and now have to wait until the 9/12/25

Any advise will be extremely appreciated.
