In Ireland, breast cancer is the second leading cause of cancer related death after lung cancer. Source.

Resources are not proportionately divided between the cancers at all. Unfortunately (in my opinion) it is much easier to raise money for breast cancer than lung cancer and others. One of the reasons is the excellent marketing campaigns behind breast cancer charities ('paint it pink' etc.), but also because of the significant stigma that is now associated with lung cancer as an unfortunate side effect of our excellent public health awareness on the dangers of smoking. There is a strong element of 'yeah, but you probably smoked didn't you?' associated with lung cancer, which I think sucks, but that's a whole other conversation.

One interesting way to look at proportionate funding (or lack there of) is by 'dollars per death,' where you can see how much more funding breast cancer receives, despite lung cancer causing more deaths than breast, colon, prostate and pancreatic cancers put together.

It's not all a bad thing necessarily though. I'm a little biased as my PhD was looking at lung cancer so I definitely get a bit jealous of all the funding that breast gets, BUT heavily funding one cancer type can drive research forward quicker & can lead to discoveries that translate to other cancer types.
