Cycling’s governing body will reveal their response to the United States Anti-Doping Agency’s (Usada) report into Lance Armstrong on Monday.
The International Cycling Union (UCI) could back Usada in stripping the Texan of his seven Tour de France titles.
However, it could also take the matter to the Court of Arbitration for Sport.
“I’ve been better, but I’ve also been worse,” said Armstrong in a speech on Friday to mark the 15th anniversary of his cancer charity, Livestrong.
“It’s been a difficult couple of weeks, for me, for my family, for my friends, for this foundation.”
Armstrong, 41, received a life ban from Usada for what the organisation called “the most sophisticated, professionalised and successful doping programme that sport has ever seen”.
The American, who overcame cancer to return to professional cycling, won the Tour de France in seven successive years from 1999 to 2005.
He has always denied doping but chose not to fight the charges filed against him.
Usada released a 1,000-page report earlier this month which included sworn testimony from 26 people, including 15 riders with knowledge of the US Postal Service Team and the doping activities of its members.
Usada praised the “courage” shown by the riders in coming forward and breaking the sport’s “code of silence”.
Armstrong, who retired in 2005 but returned in 2009 before retiring for good two years later, has not commented on the details of Usada’s report. His lawyer Tim Herman, however, has described it as a “one-sided hatchet job”.
Tour de France director Christian Prudhomme said there should be “no winner” of the Tour for each of the seven years where Armstrong won if the decision to strip him of his victories is upheld.
Last week, Armstrong lost three of his main sponsors with sportswear giant Nike, cycle maker Trek and Budweiser brewer Anheuser-Busch all cutting ties with him.
Armstrong has also stepped down as chairman of his cancer charity Livestrong.
