David A. Dawson seeks review of the Social Security Administration’s denial of disability insurance benefits to which he claims entitlement. The Administrative Law Judge held that Dawson was not disabled on or before December 31, 2000, when he was last eligible for such benefits. Dawson argues that the facts show he was disabled beginning October 28, 1998. 2 We review a final decision under 42 U.S.C. § 405(g) to determine whether the decision was supported by substantial evidence in the record and whether the proper legal standards were used in evaluating the evidence. Greenspan v. Shalala, 38 F.3d 232, 236 (5th Cir. 1994).

There is little evidence to suggest that Dawson could not perform “light work” prior to January 2001, when colon cancer was first suspected. The medical records on which Dawson relies show only that he sought treatment for a groin abscess in October 1998 and again in June 1999. In early 2001, he denied any prior medical problems other than the abscess. A medical expert reviewing the medical records concluded that Dawson’s only functional limitations occurred after surgery in 2001. We find that the record provides substantial evidence to support the Commissioner’s decision that Dawson was not disabled on or before December 31, 2000, when he *279 was last eligible for Social Security disability insurance benefits.

AFFIRMED.
