B.C. study offers a ray of hope for incurable cancer patients
Retired teacher Daphne Quance has incurable colo rectal cancer, and she's putting a big chunk of faith for survival on a study she has joined that uses high doses of vitamin D.
Vitamin D is naturally derived from exposure to the sun. It can also be taken as a pill. Yet many studies have shown that Canadians have less than optimal vitamin D levels, especially during the winter.
Research has suggested vitamin D may play a role in preventing cancer or extending life once diagnosed.
Quance, a 76-year old North Surrey resident whose colon cancer was diagnosed in 2012, believes the Vancouver-based study of 50 patients like herself will yield important information.
