CHICAGO -- Hall of Fame second baseman Ryne Sandberg says he is cancer-free.

The Chicago Cubs great made the announcement on Instagram on Thursday, nearly seven months after he announced he had metastatic prostate cancer.

"Rang the Bell this morning!" he wrote. "WE did it, WE won! What a Dream Team, family, doctors, friends, nurses, fans who supported myself and Margaret through the last 8 months! We feel so blessed from all the love, prayers and thoughts and positive words that have come our way! Modern medicine has come along way so once again early detection is important. Annual doctor visits! Time to celebrate! #godisgood."

Sandberg, 64, has kept well-wishers updated on his progress through his Instagram account and said last month that scans showed no signs of cancer.

Sandberg hit .285 with 282 homers, 1,061 RBIs and 344 steals in 16 seasons in the majors. He made his big league debut with Philadelphia in 1981 and appeared in 13 games with the Phillies before he was traded to the Cubs in January 1982.

Sandberg turned into one of the majors' best all-around performers with the Cubs. He made 10 All-Star teams and won nine Gold Gloves. He also was the National League MVP in 1984.

He was inducted into Cooperstown in 2005. In June, the Cubs unveiled a statue of Sandberg outside Wrigley Field in a ceremony emceed by Bob Costas, 40 years to the day he hit a pair of late homers in a nationally televised win over St. Louis. The statue depicting him crouched and waiting for a grounder is next to bronze tributes to fellow Hall of Famers Ferguson Jenkins, Billy Williams, Ron Santo and Ernie Banks.
