Rather than a Wolverine blood transfusion, Ryan Reynolds' Deadpool is pumped full of an unnamed serum that awakens any latent mutant genes present in the victim's body. It turns out, Wade was born with a healing factor that never manifested itself. After the serum, Ajax tortures Wade until his mutation shows itself.
Wade Wilson received a serum injection to activate his supposedly dormant mutant genes. To catalyze the serum, Wade accepts torture to secrete adrenaline in his body, and the serum works on his body, helping his cells regenrate at a rapid speed.
When the experiment conducted on Wade gave him superhuman healing, he became unkillable but was not immune to old age. However, that changed after some time due to the most unimaginable thing possible. So, Deadpool is immortal because he has a curse from Thanos, granting him eternal life.
What was Deadpool's job before he became Deadpool?
Throughout the ambush, Wilson shows the viewer the events leading to how he became Deadpool. 2 years ago, Wade Wilson (Ryan Reynolds) is a former special forces operative who works as a mercenary in New York City. Wilson was dishonorably discharged as a Canadian special forces operative.
This question is answered by the fact that Deadpool's cancer hasn't actually been cured but simply put on pause, meaning it is constantly battling with his healing factor, causing his severe disfigurement, which will assumedly still be in place when Deadpool joins the MCU in Phase 5.

Why is Deadpool disfigured if he can heal?
It has been revealed that at the time his healing ability was given to him, Deadpool suffered from some form of cancer; after the healing factor was given to him, it made his normal cells as well as his cancerous cells unable to die, giving him a heavily scarred appearance beneath his suit.
Along with his extra mutant powers, one of the things Stryker did to Wilson was have his mouth surgically shut, making him the perfect soldier in Stryker's eyes. In the post-credits scene his mouth is partially open. This is probably because of the damage sustained in the fall.
A fairly unknown fact about Deadpool is that he is weak when in contact with heavy Gamma radiation. Prolonged exposure to Gamma radiation significantly reduces Deadpool's regenerative abilities, making him easier to take down.
Months later, T-Ray, now an agent of Thanos resurrects Deadpool, who has been killed in a fight with Weapon X, using an artifact Thanos gave him to create many copies of Deadpool. Thanos is jealous of Deadpool's relationship with Death and T-Ray is to "curse him with immortality" so that he may never see Death again.
His power is so effective that it allows him to be immortal despite him carrying his cancer. But that doesn't mean he is unkillable. One way of killing him is to put a mutation-dampening collar on his neck. It will disable his regenerative ability and allow the cancer cells to grow, thus deteriorating his body.
In Deadpool Annual 2013, Deadpool is ripped apart by Luke Cage and Thor. He's split straight down the middle, but he had been melded together with Madcap for the duration of the issue, so the two halves simply become each of them. Since there was no technical injury, the two guys come out unscathed and fully formed.
Training: He has been highly trained in swordsmanship, marksmanship, strategic/tactical planning, assassination aptitude and martial arts by Nick Fury himself as well several other master combatants.
Ellie Camacho was born after a short fling between Deadpool and Carmelita Camacho. With Deadpool unaware of her existence, Ellie was raised by her mother until she was kidnapped by a Weapon Plus operative named Butler.
Deadpool decides to see Black Talon on Taíno Island about the situation. He does not know what is going on either, but he does reveal to Wade that he has been cursed by Thanos which leads Deadpool to the assumption that Thanos must have kidnapped Death. Therefore, Deadpool plans on rescuing and freeing Death.
There are two things though, that scare him above all: cows and clowns are a Deadpool weakness. Wilson's always been scared of cows because he believes that their eyes are all-knowing. The Merc is also scared of clowns, finding them too creepy.
Funny enough, Domino isn't the only one with a fear of a particular animal, as Deadpool tells her he's scared of cows while gaining the information from her.
So, Deadpool's main superpower is his healing factor, and what a healing factor it is. In multiple comics over the years, it's been established that Deadpool's healing factor is more powerful than Wolverine's. Deadpool can survive anything. If his head is cut off, he'll regrow his body over a few weeks.
Yes, Deadpool feels every bit of pain as normal humans do. However, his regenerative ability allows him to heal from all injuries. While Deadpool can heal quickly, he isn't indestructible.
In Deadpool (2016), set in a revised timeline created by the X-Men. This version is a mercenary who is diagnosed with late-stage cancer and turns to Weapon X after he is offered a cure.
Most likely, Deadpool would have to place his head back onto his neck, and it will then Regenerate in that location. This is also seen possible because of this, yes I know this is just epic cover art to build suspense, but it shows us that Deadpool can actively hold his head rather than it just regenerating instantly.
X-Uniform Variant: When Deadpool joined the X-Men, he wore a variation of their Yellow and Black Uniform with X-Men written across the chest. He continued to wear his original mask.
