“I’ve lost 40kg in a year ... I don’t know how long I have left to live, but I’m not interested in living like this anyway,” said the 82-year-old.

Toscani said he was considering calling his friend and right-to-die activist Marco Cappato, who has accompanied many Italians to Switzerland’s Dignitas clinic, despite assisted suicide being officially banned in Italy.

He said he would like to be remembered “not for any one photo but for my whole work, for the commitment”.

Toscani courted controversy with Benetton photo campaigns, once showing an AIDS sufferer as a pietà.

Another controversial photograph contained three identical hearts labelled black, white and yellow, while other photos were against war, religion and capital punishment.

Other snaps included a jean-clad backside captioned ‘whoever loves me, follow me’, a priest kissing a nun, the faces of men condemned to death and the body of a woman with anorexia.

Amyloidosis is a rare disease characterised by a build-up of abnormal protein deposits in the body.
