Cardiff Blues club captain Matthew Rees has been cleared to return to full-time training.
The 33-year-old Wales international hooker announced in October that he was to take a break from rugby in order to have "extensive treatment" for testicular cancer.
After undergoing screening and testing he has now been told he does not require any additional medical treatment and can build up his fitness ahead of a return to action.
Rees, who joined the Blues from Scarlets last summer, told his club's official website: "It is a massive weight off my shoulders and while there has always been light at the end of the tunnel for me during difficult times this is the news I always wanted to hear.
"Now I've been given the all clear I can concentrate on getting back to match fitness and hopefully I can play a part towards the end of this season for the Blues.
"I've been truly overwhelmed by the good luck messages I have received from the rugby world and the fantastic support I've had from my friends, family, my team-mates and staff at Cardiff Blues and the WRU throughout my treatment. It has meant a huge amount to me.
"I also want to pay a special thank you to everyone at Velindre Hospital in Cardiff, in particular the specialists and nurses on the Princess Margaret Ward for everything they have done for me."
Blues director of rugby Phil Davies said: "On behalf of all the players, coaches and staff at the Blues, we are absolutely delighted for Matthew that he's come through this ordeal. He has shown an amazing resilience and mental toughness throughout such a difficult time.
"Matthew has continued to train, with our strength and conditioning staff throughout his treatment, which is testament to his strength of character and ability to overcome adversity. Not many people could have done that while remaining so positive and determined.
"We are all now all looking forward to seeing him back on the training field and on the field in a Cardiff Blues jersey in the future. This news is a massive boost to everyone, but nobody more than Matthew and his family."
