Paul Canoville has been offering invaluable advice during a question and answer session on his experiences of dealing with cancer.
The former Blue, who now works within the Chelsea Foundation, spoke to members of the public about the disease and showed his support for Blue September by painting his face.
Blue September is a nationwide awareness and fundraising initiative concerning all the cancers that affect men. Canoville himself has battled back from non-Hodgkin's lymphoma, an aggressive form of cancer which attacks the immune system. He made a full recovery of undergoing a course of chemotherapy for the illness.
The past player was speaking at Wellington Hospital in St John's Wood, which held a day of activities in an attempt to raise awareness about men's cancer.
There was an exhibition of the daVinci Simulator, which is a replica of the £1.5 million robot consultants use to perform robotically-assisted cancer operations and is at the forefront of cancer with robotic surgery. Staff at the hospital were joined by members of the public and encouraged to use the training simulator and see the control mechanisms for themselves.
Local GPs were invited to listen to four of the hospital's leading, robotically-trained surgeons, who spoke about prostate cancer surgery techniques, and discussed how GPs can help their patients with prostate cancer.
Members of the public were also given gifts to take away, including blue hand warmers and cancer care booklets from Macmillan and Men's Health Forum.
