Delete links if they are not pointing correctly

[bmamlin]

Just delete the last two links:

<li><a href="http://www.cancercare.org/publications/24-understanding_and_managing_chemotherapy_side_effects" onclick="popblank(\'\');" target="blank">Managing Treatment and Side Effects</a><br />(Cancer Care Online)</li>
<li><a href="https://www.oncolink.org/support/side-effects" onclick="popblank(\'\');" target="blank">Side Effects</a> (OncoLink&#174;)</li>
