Eileen Posner, Apri 24. A cancer survivor who lost all her hair to chemo kept a year-long photo diary showing her changing appearance as she went through recovery. See SWNS story NYCHEMO. Mom-of-two Eileen Posner, 41, had long, flowing locks before she was diagnosed with aggressive breast cancer but went bald as a result of life-saving treatment. In total, she had six doses of chemo as well as undergoing radiation therapy and a double mastectomy to remove a mass on her left breast. Chemotherapy kills cancer cells but also affects hair root cells which resulted in Eileen's head hair, eyelashes and eyebrows falling out. The mom, who works in finance, said it was "more traumatic than losing my breasts" and that strangers gave her looks of pity whenever she went out in public. Six weeks after undergoing her final chemo session last April, the first tufts of hair began to reappear on Eileen's head. She decided to document the progress and while the growth was slow at first, pictures show her brunette mop becoming fuller as each week goes by.
