Handle all checkbox events on a single method

I found some similar questions but none of them on C# Winforms. I have many similar methods for different Checkboxes I have on my form, but now the number of checks is about to double and I'm looking for a simpler way of doing this.

Here's an example:

private void CheckPET_Click(object sender, EventArgs e)
{
    if (CheckPET.Checked)
    {
        CheckAdicionarMaterial("PET");
    }
    else
    {
        if (Confirmacao())
            CheckRemoverMaterial("PET");
        else
            CheckPET.Checked = true;
    }
}

I have one of these for each Checkbox, and all of them follow the same pattern, so if I could have a method that handles all clicks I could do something like this:

private void GenericCheckbox_Click(object sender, EventArgs e)
{
    if (Checkbox.Checked)
    {
        CheckAdicionarMaterial(Checkbox.Text);//The text of the boxes is always the string I want to pass here.
    }
    else
    {
        if (Confirmacao())
            CheckRemoverMaterial(Checkbox.Text);
        else
            Checkbox.Checked = true;
    }
}

What can I do to achieve this?

If I understand the question correctly - binding a single function as an event handler for several checkboxes?

private void checkBox_CheckedChanged(object sender, EventArgs e)
{
   CheckBox checkbox = sender as CheckBox;
   if (checkbox == null) return;
   if (checkbox.Checked)
   {
     CheckAdicionarMaterial(checkbox.Text);//The text of the boxes is always the string I want to pass here.
   }else
   {
     if (Confirmacao("Desmarcar removerá todas ocorrências do material. Continuar?"))
       CheckRemoverMaterial(checkbox.Text);
     else
         checkbox.Checked = true;
   }
}
