Breast cancer is really a hot topic, and I think a lot of the fundraising and work done has rallied many people together and that makes news. I don't think it's selfish to want more focus on your type of cancer at all-- we're all like parched sponges looking for more information and others with similar cancer experiences.
Before having cancer, I always thought of breast and prostate cancer, because those are the ones that come to my mind first. If you ask me now-- you're going to get an earful about lymphoma. :) Yes-- breast cancer has some amazing support, but research being done for that specific cancer does also help other cancers too. I feel confident that many medicines I take for my lymphoma and complications began its life via breast cancer research.
There are many scientists and doctors out there today tinkering with new ideas for any type of cancer imaginable.. I just think the news has to be dug up :) I don't know how people did it before the internet.
