Align Checkboxes

I want to align my checkboxes in my site and I did some search over the stackoverflow and I found some solution that couldn't help me to align me checkboxes as I want. The first solution-question and the second solution-question.

My checkboxes look like the image below...

The RED line is where I want all my checkboxes to be.

Here is the code for my checkboxes...

    <label id="Disease">Disease:</label><br />
    <!--emfanizei tis epiloges gia ta diseases me basi auta p exoume sti basi mas -->
    <?php
  $sql = "SELECT name FROM disease";
  $query_resource = mysql_query($sql);
  while( $name = mysql_fetch_assoc($query_resource) ):
?>
    <span><?php echo $name['name']; ?></span>
    <input type="checkbox" name="disease[]" value="<?php echo $name['name']; ?>" /><br />

<?php endwhile; ?>

Can you help me please?
