Why does prostate cancer only get 2-5% of funding breast cancer gets?

Sorry @vancouverislandhiker, but I think you've got really inaccurate numbers (at least when I look at the USA). On average, breast cancer kills more people in the USA each year than prostate cancer (by 20%). Further, looking at the National Cancer Institue funding stats Colleen posted on her first link it appears fairly constant that prostate cancer research funding is about 50% that of breast cancer research funding. However, further inspection reveals that the total funding for ovarian and uterine cancer deaths (solely female afflictions) is about 50% of prostate cancer research even though total ovarian and uterine cancer deaths are about 75% of male deaths from prostate cancer. So I don't see a gross imbalance here (except maybe for uterine cancer which has very little funding at all compared to the number of women it kills each year). Rather I suspect the funding allocation is probably a complicated topic dependent on many factors.

More people die of prostate cancer now than breast cancer. This has been true since the 90s. Funding research makes a difference. Bless you and your work, James.

100% in agreement Miss Young - all cancer patients deserve respect, support and quality care. What I advocate for is more money into research given mortality and other drivers. When I ask large corporate donors on why they gave money to this group or that group, it is interesting to hear the rationale. From a donor standpoint, there is definitely a lack of understanding on where to put this money and where it could benefit the most, given the limited amounts of donations . Last winter I was able to do some significant fundraisers for prostate cancer, breast, cancer, colon cancer, and other awareness campaigns in the Philippines. The people in the smaller villages are basically left without medical care or any form of awareness. With prostate cancer, you cannot wait until you get neurological symptoms before you start treating it. Your best open window of opportunity is before you get the symptoms. Dr's here are coached not to give a PSA test unless there is 'direct and substantial urological issues ' with the patient . This, of course , is cause for concern !, as your best treatment window, I am told from the Urologists, presents itself while there is no urological issues. In the Republic of the Philippines (RP) I raise enough money to get a specific type of machine for breast cancer imaging and also I raised enough money to get some advertising awareness and free PSA checks for men in the provinces- forgotten people for the most part. From my memory, I got the PSA test down to about $12.84 Canadian. Small price to pay for early detection. We will be able to test thousands and thousands of men in this campaign I hope. The real problem is if their PSA is over 4.0 and the urologist wants to proceed with some sort of corrective care, Phil health will only pay for approximately 80% of the surgery. Also, a concern of mine is money and corruption in the Philippines, but that is a long and another story for a later date. I have much more work to do in the Philippines as well as some other deserving countries that I'm working on as well. I have made it my life effort to make people aware of various types of cancers and to raise money for early detection and cancer care. It's truly amazing, as a sidenote, the culture in the Philippines is to stay away from hospitals and doctors as much as possible so, we had to get some friendly faces on posters and very encouraging statements to try and get these men and women into the clinics for exams. Next time I'm over in the Philippines, I want to get some meetings with Phil Health , which is the government insurer, to see if we can do something similar to their program with tuberculosis. Their tuberculosis program is to be commended. It is free, and testing is free at any rural clinic or hospital.They have an excellent screening program for tuberculosis and care and I would like to ask them if they could do that for prostate cancer, breast, cancer, colon cancer and heart, and stroke issues( which is very common amongst the people in the archipelago, mainly due to the rice diet, I think ! Tasty rice for sure , but very meal leads to diabetes as well as other factors.). It's quite amazing that the climate is one of the best to grow vegetables, fruits, as well as other things .... but Rice is the staple of Course , and vegetables and fruits are not eaten as much as it should be. Probably a lack of that education is also needed.). Actually I grew up there as a 'foreigner' kid, hence I know their diet well. God bless you all. James .

@gently -- respectfully, you're just flat wrong that prostate cancer kills more people than breast cancer. I respectfully suggest you're getting bad information.
Here's some links you might be interested in:

But I did see that in the UK prostate cancer has edged out (just barely) total deaths over breast cancer in 2018 in the UK, but certainly not "since the 90's".

@retired guy, I yield. https://blogs.bmj.com/bmjebmspotlight/2018/03/09/prostate-cancer-now-kills-more-people-than-breast-cancer-cause-for-alarm/#:~:text=The%20death%20rate%20from%20prostate,older%20is%20216%20per%20100K. and thank you for the correction.
I have been impressed with the quality of care available for prostate cancer patients compared to ovarian and breast cancer patients. Though my view is limited.
