Boats said a lot that is very true. Like him, in '97 I came down with cancer, an unusual form. In '98 was told I was in my 4th stage, 6 months or less to live. A positive attitude helped, having people coming around saying, "Oh I'm so sorry" did not. A big key here is finding the right doctor. They are sure as hell not all the same.
Laughing is also a very positive thing, medically!
An aggressive cancer is large cell cancer. Bad news is it attacks very fast. But the good news is it can be cured, not just put into remission like the small cell type.
An old friend who is a police detective came down with an aggressive form of leukemia (blood cancer) about 16 months ago, he was sort of stabilize with a cocktail of chemotherapies then went to see the top guys in Boston. Derrill went back to work in April, he really isn't dead. (That man was ugly when he was hairless.)
Yes, sometimes people do die of cancer, there is no sugar coating that. But an aggressive cancer is no longer an automatic death sentence. The medical improvements in just the last few years are mind-blowing.
I'll pray for your home boy, no doubt in my mind that does help.
There are a lot of useful cancer sites on the computer, that might help him, the family and you understand what's going on and what some of the options are. Sometimes doctors just don't take the time to explain things and a lot of times patients don't ask the right questions. Remember anything written before 2000 is ancient history and probably no longer applies.
I've spent time with people who received the news that they have cancer, in the last few years. I'm no expert but it's surprising how many people know they are going to die of cancer and don't.

Stay healthy,
