Bringing hope for cancer patients

it's a shock for me when I heard that 2 of my friend's parent passed away in 2 days time. and I heard about friends of my friends who are still young , just like my age, found tumors after checking up in hospital.

What I really doubt is, 

how a doctor inform these news to them? 

is cancer = death?

What will be the reaction when one heard the news of cancer decease?

How are they going to overcome the pressure after hearing this news? (mentally & physically)

I went to a seminar on 12 April, and it's organised my Tombo Enterprise Sdn Bhd
