As soon as any person think that they might have any form of cancer before the internet, they struggled to get relevant information. Once they were diagnosed, they needed to find a person or group that have already gone through what they are going to experience, 
These days, as soon as you think or are diagnosed with cancer, one can find a lot of information specific to their condition. With the tapping of a couple of buttons, the relevant information is displayed and you can gather more information from the internet than from your local doctor.
Some doctors even follow the new developments about the treatment of specific conditions in the internet where fellow doctors post articles about the successes and failures of some treatments.
Communications between doctor and patient are also made easier by e-mail.
So a big thank you to the internet for enabling us to find information so easily.
