The Chelsea defender, 26, was forced to withdraw from the Three Lions squad for Euro 2012 after suffering a broken jaw in their final warm-up game against Belgium.
Cahill was in superb form heading into the European championship, with the former Bolton Wanderers skipper playing a key part in Chelsea’s Champions League success.
But with Phil Jagielka and Joleon Lescott both impressing in recent games for England and competition from his Blues team-mate John Terry, Cahill acknowledged it will be tough to break into Hodgson’s side.
“I was gutted to miss out on the Euros because it was the first big tournament I was going to have a part in, ” said Cahill.
“To get the blow literally just before we flew off was devastating.
“I was holding onto a bit of hope that I might get there until they had to put metal plates into my mouth and an elastic band to keep the jaw in place!
“Now I’m back fit but there is real competition and I think myself not making the Euros has made it harder in one way.
“I thought the lads did well in the Euros so, for me not being able to stamp my authority in that tournament, has made it another fight for me to get back involved and get the starting place.
“There is great competition, Jagielka scored against Italy and Joleon Lescot had a great Euros. Terry is well known and proven for many years.
“The lads who are picked want to keep hold of the shirt. It is going to be tough but it is a fight I’d had since I’ve joined because we are blessed with some good players in England.”
