Why National Family Health History Day is Important
It's about family
Family time is special and Thanksgiving is one of the most wonderful days of the years simply because everyone comes together to share a meal, watch a game, and rehash old family stories. But this year on Thanksgiving, also known as National Family Health History Day, spend some time educating each other. Young people often don't realize how important it is to know about hereditary factors that could cause trouble down the road when they marry or have children. This year, in between the pecan pie and kickoff, have a serious discussion about your family health history.
Know the risk factors for colorectal cancer
Colorectal cancer is a cancer of the bowels. It is the second leading cause of cancer death in women and the third leading cause of cancer death for men. Some of the risk factors include obesity, diets high in red meat, age, sex, and most importantly, a family history of colorectal cancer. That history is increased when a first-degree relative including a parent, sibling, or child is affected. That's why it's so important to discuss family health history when the entire family is present.
It's preventable
It's important to note that many of the risk factors for colorectal cancer are preventable. However, the best way to get the jump on this disease is to have a colonoscopy. Screening guidelines vary for those with high risk, but most healthcare providers recommend earlier cancer screenings, especially when there is a family history of this specific kind of cancer.
