March marks Colorectal Cancer Awareness Month, and the team at IVGA wants to emphasize the importance of getting screened! Remember, colon cancer is both preventable and treatable. We advise individuals to undergo screening at age 45, or earlier if there's a family history of colon cancer.
Spread the message and prioritize GETTING SCREENED!
