How to prevent multiple pages opening while clicking the Items in Master Detail page?

Steps to reproduce the issue 1. clicking the item in details page. 2. Page will open and 3. again open the page and 4. clicking the same item another item page will display on the existing item page

void  OnTapGestureMenuTermsAndConditionsTapped(object sender, EventArgs args)
{
    IsPresented = false;

    Detail.Navigation.PushAsync(new AgreeTerms());
}

EDIT

First of all i given clarification on my issue

AgreeTerms() are sup-rate page and

This page, I navigate the page through masterpage(Menu page, Here I give the link to navigate "AgreeTerms" page), While click on link "AgreeTerms" page open and again click same link page open another page(overlap previous page), The Code to navigate page in masterpage , 

void  OnTapGestureMenuTermsAndConditionsTapped(object sender, EventArgs args)
{
    IsPresented = false;

    Detail.Navigation.PushAsync(new AgreeTerms());
}

and while navigate the page(AgreeTerms) , I want to close the page(AgreeTerms) again, Here I write the code , This is code in AgreeTerms page 

private async void Deleteimg_Tapped(object sender, EventArgs e)
{
    if (Navigation.NavigationStack.Count > 0 || Navigation.NavigationStack.Last().GetType() != typeof(AgreeTerms))
    { 
        Navigation.PopAsync(false); 
    } 
}

You can do it like this:

void  OnTapGestureMenuTermsAndConditionsTapped(object sender, EventArgs args)
{
   IsPresented = false;

   if (Navigation.NavigationStack.Where(x => x is AgreeTerms).Count() > 0)
       return;
   Detail.Navigation.PushAsync(new AgreeTerms());
}

The question a little confusing, but I think that you want to prevent the same page from opening twice.

If this is the case, you could check current page's type and only Push if it's different from the type that will be pushed. Like so:

void  OnTapGestureMenuTermsAndConditionsTapped(object sender, EventArgs args)
{
    IsPresented = false;

    if (Detail.Navigation.NavigationStack.Last().GetType() != typeof(AgreeTerms))
        Detail.Navigation.PushAsync(new AgreeTerms());
}

Hope it helps!

EDIT

Forget about Deleteimg_Tapped, you can delete this method from AgreeTerms.

You only need to change the OnTapGestureMenuTermsAndConditionsTapped to the code that I posted up here.

If you change from this:

void  OnTapGestureMenuTermsAndConditionsTapped(object sender, EventArgs args)
{
    IsPresented = false;

    Detail.Navigation.PushAsync(new AgreeTerms());
}

To this:

void  OnTapGestureMenuTermsAndConditionsTapped(object sender, EventArgs args)
{
    IsPresented = false;

    if (Detail.Navigation.NavigationStack.Last().GetType() != typeof(AgreeTerms)) // Only add this line
        Detail.Navigation.PushAsync(new AgreeTerms());
}

It will work.
