What illness did Pablo Neruda have when he received the Nobel Prize?

When Pablo Neruda was awarded the Nobel Prize for Literature in 1971, he was already suffering from prostate cancer.1

Following his trip to Stockholm to accept the award, he returned to Chile in a bedridden state. While his death certificate initially cited wasting due to cancer as the cause of his passing in 1973, the exact circumstances of his death have remained a subject of ongoing investigation and controversy.1
