The bad: She's developed squamous cell carcinoma (skin cancer) under the tail. She's about 6 yrs old
The good: She produces at least a quart of milk a day. Rich creamy milk. Besides the cancer, she's healthy and friendly. She even adopted another kid.
From what I've read you can still drink the milk but it's not recommended as the wound might get infected that could affect the milk. Sounds like there are mixed results with treatments.
