As we said, lumps aren't the only symptom. For Katherine Vessy, she first noticed a bruised feeling around her ribs, and then "what felt like a piece of string" just under her skin. After checking with a doctor, she was found to have Mondor's disease.
She was told it was caused by injury or exercise and was relieved by the diagnosis. But then it turned into so much more. In rare cases Mondor's disease is actually a symptom of breast cancer, and when she had an ultrasound doctors discovered two lumps.
"The two lumps were very dense. I could just see two dense lumps staring back at me," Vessy said. "The last time I had an ultrasound was when I was pregnant [with the twins] but rather than seeing two heartbeats it was these two, dense horrible lumps... It was horrendous."
"All I was looking for was how long have I got left? I just didn't know anything about it. I was waiting to be given my death sentence."
Vessy has gone through treatment but it took its toll. "I feel like I am about 10 years older than I was. There's an expectation that you'll just bounce [when you stop treatment]. I just had no feeling of elation at all."
