According to the Prostate Cancer Foundation, 97% of men who are diagnosed with prostate cancer are age 50 or older, and 60% are over the age of 65. In that regard many who are afflicted with it have been privileged with longer lives than many living in dire impoverishment who will not survive their childhood. The reason the countries with the highest life expectancies are among those with the highest rates of cancer is that the risk of many cancer diseases increases substantially with age.
Still to call any cancer a "hallmark of privilege" is crass. There are many people who are living in First World countries who have still struggled through financial hardships, and the diagnosis of cancer can exacerbate them considerably, especially in the United States. Even if the person diagnosed with cancer has insurance, there are frequently expenses that are not covered by it and / or require an incredible amount of hassle for approval. It's not uncommon for medications that are vitally imperative for some patients to be routinely denied by their insurers, like Neupogen which is outrageously expensive even if you can get the new generic version of it. Many people who are diagnosed with prostate cancer are elderly and do not have the income they once did, or the vitality to withstand treatment and recover from it. Many also ate healthily and took care of themselves. Cancer is like a beast. It doesn't care if you are a billionaire like Steve Jobs (who did not have prostate cancer but nevertheless did die from cancer, and did leave behind children still in their youth) or a widowed pensioner struggling to pay the mortgage every month. Even if you have led a privileged life, wealth will not inoculate you from the physical and emotional suffering that comes with prostate cancer.
And....... I'm a feminist, as are many of my friends, family, and professors. I've helped with Movember fundraising events that raised substantial money specifically to help men who have prostate and testicular cancer. It's a sizable amount raised and it goes towards tangible needs such as for assistance in paying for medical expenses and other significant expenses. This month we also started a new effort to help pay for the travel expenses many patients have because local treatment isn't available.
