The founder of prostate cancer awareness group The Red Sock Campaign has told ITV Cymru Wales it's not just men who need information and support.
Keith Cass founded the group when he was diagnosed with terminal prostate cancer himself.
He said: "It's about supporting anyone who's affected by prostate cancer, and by that I mean the wives, the children and the partners.
"Quite often I get an email from someone and it won't be the patient themselves, because those caring for those with prostate cancer have just as many issues."
This Father's Day, ITV has teamed up with the charity Prostate Cancer UK to ask people to stand by the men in their lives and unite in the fight against prostate cancer.

Prostate cancer is the most common form among men - with one dying every 49 minutes.
Today, ITV has launched a campaign with Prostate Cancer UK, asking people to make a pledge to make sure the men in their lives know about the disease.
Charles Dance, the actor and supporter of the Stand By Your Man Campaign, has encouraged men to have a "very simple, routine test" for prostate cancer.
"A lot of men live with the symptoms and hope that it's going to go away, or just be certainly reluctant to talk about it." the 67-year-old said before urging men to go for the test.
The Game of Thrones actor said the new film Father's Day, which he describes as "beautifully written", aims to raise awareness of the issue.
Every year almost 2,400 men in Wales are diagnosed with prostate cancer and over 550 die from the disease.
