Dog's breast cancer mirrors owner's battle as both beat the disease

A UK woman battling a second breast cancer diagnosis adopted Dolly in 2018 for support; years later Dolly was diagnosed with breast cancer and underwent a mastectomy, with the cancer described as low-grade and requiring no further treatment, and both dog and owner are now cancer-free. The owner carries a BRCA2 gene mutation and also had a double mastectomy, illustrating the deep bond with a pet that can accompany and comfort patients through cancer treatment.
