Yes. More education.
In the meantime, language such as this “Cervical cancer is a cancer that’s found anywhere in the cervix and mostly affects women and people with cervixes under the age of 45” is rather confusing. So, what other people
have cervixes that are not female? Remember, this is supposed to be plain English so the maximum of women can understand that this is aimed at them.
I suggest you read this press release thinking about the people who don’t understand they have a cervix. Because, this really is a confusing piece of communication. But yes, education is needed.
AND in the meantime, clear communication. So you are quite wrong in that the issue in your positioning this as not a language and communication issue, which I can only assume you are trying to do.
And again, this thread is about that signage.
