When researching with Google it's best to steer away from all the old "scary" information and research current topics.
To do this; (1) type your search word and click enter, (2) select <Tools>, (3) click <Any time>, (4) select a more current time like <Past year>, <Past month>, <Past week>, <Past 24 hours>, or <Past hour>.
In the world of CLL, things are changing rapidly so it's best to have the most current information.
