Preventative Screening
My mom had uncomfortable digestive symptoms for a year or so that couldn’t be explained. Her doctor ordered a colonoscopy and discovered colon cancer. She quickly had surgery and recovered well.
She decided that it was important that my dad be screened just in case. Turns out he also had colon cancer. Six months after my mom’s surgery, my dad had a portion of his colon removed as well and recovered quickly.
After recovery, my mom still had the same initial symptoms. It turns out she was lactose intolerant. Since both parents had colon cancer and no telltale symptoms, my mom decided I needed to be screened as well.
So my mom becoming intolerant to lactose later in life lead to me getting an otherwise completely uncalled for colonoscopy at the age of 27.
