The 100k story has more to it though, here's the quote.
"Smith asked the UFC for a two-fight extension worth $100,000 per appearance. The UFC declined, so she then countered with an offer to keep fighting at her current pay rate. The promotion declined that offer as well, according to the fighter."
The tumour came about after she went on TV and said she had a Benign tumour that her health insurance doesn't cover. The UFC then contacted her and got it removed, presumably as it was bad press for them not too.
Here's the text of the tweet.
"In any relationship a person is only lets themselves be treated as badly as they feel they out to be treated. UFC fighters- your employer relationship is abusive. Stop letting them undervalue your worth. Man up, Woman up, Sign an authorization card."
No mention of husband and the point is about only being treated badly as you allow.
Also Tumour wasn't malignant but benign and could be seen in her weigh-in photo's the last few years.
"“It’s a benign tumor,” Smith told MMAjunkie. “I’ve asked quite a few doctors about it, and they’ve always told me that it’s not going to kill me or anything, and that’s always nice to hear when you have growths on your body. But I don’t want this thing on my body anymore. I want to get rid of it, and I’ve wanted to get rid of it for a while.”
Here's the complete context so folk cna make up their own minds.
