The past year has seen more debate about the best way to find breast cancers.
A recent analysis concluded that regular mammograms haven't reduced the rate of advanced breast cancers — but they have led more than a million women to be diagnosed with tumors that didn't need to be treated.
It's well-known that chemotherapy often comes with side effects like fatigue, hair loss and extreme nausea. What's less well-known is how the cancer treatment affects crucial brain functions, like speech and cognition.
For Yolanda Hunter, a 41-year-old hospice nurse, mother of three and breast cancer patient, these cognitive side effects of chemotherapy were hard to miss.
"I could think of words I wanted to say," Hunter says. "I knew what I wanted to say. ... There was a disconnect from my brain to my mouth."
