How far have we come in the war on cancer? The PBS film The Truth About Cancer addresses this question as filmmaker Linda Garmon tells the stories of several patients’ battles with the disease, including that of her husband. The film will be shown on Thurs., July 10 at 6:30 pm in the Downtown Library 4th Floor Meeting Room. Linda Langmore, MSW, St. Joseph Mercy Health System Cancer Center, will lead a post-film discussion.
