Reality TV star Diem Brown has died of cancer at age 32, after chronicling her long fight with the disease and becoming an advocate for other patients, reports People. Diem first appeared on MTV's Real World/Road Rules Challenge in 2006, announcing in her debut season that she had just been diagnosed with ovarian cancer.
