Benign means, harmless, like a benign tumor, or kindness, like "ah to be young and benign" or to resemble someone like "you benign god"
no
Not malignant, noncancerous
I am not a medical professional, but I am quite confident that a benign tumour is one that is believed to be non-cancerous. So its good news to hear that a tumour is benign.
Benign means innocent , non malignant.
