The American Cancer Society announced plans Monday for its annual Relay for Life event in southern Berks County.

The 24-hour event will begin this Friday at noon at Twin Valley High School in Caernarvon Township.

Addressing participants during the survivor ceremony this year will be Barb Freeman, a 48-year-old wife and mom who is a two-time breast cancer survivor.

In April 2009, doctors discovered that Freeman's cancer had spread to her brain, giving her less than a year to live. Freeman, however, is still going strong four years later.

More than 300 people are already signed up to participate in the event, which is open to the public.
