Goh was diagnosed with bladder cancer in September 1983 and he retired from politics in December 1984. He kept a low profile but remained active with various organisations where he served on the board or as an adviser. After he married Phua Swee Liang in 1991, the couple travelled widely to places such as Australia and Hawaii. However, a series of strokes in the late 1990s and early 2000s took a heavy toll on him. He was bedridden in his final years and died on 14 May 2010.
