Breast cancer research has been funded more extensively in the last few years. It’s evident by the enormous display of pink all throughout the world.

"The pink drives me nuts," Cynthia Ryan, an 18-year breast cancer survivor who volunteers to help women with the disease, told the Associated Press. Of course, not everyone shares that sentiment.

"Research doesn't come cheap," said a spokesman for the Susan G. Komen for the Cure -- which says breast cancer awareness efforts have helped the foundation raise hundreds of millions of dollars for breast cancer research.

There are two main types of epidemiologic research studies and these are observational studies and randomized controlled trials.

In both types of studies, the goal is to give information that helps support or disprove an idea, called a hypothesis. A hypothesis for a study might be a link between an exposure (like alcohol use) and an outcome (like breast cancer). Though they have the same goal, observational studies and randomized controlled trials differ.

Essentially, in observational studies, participants do what they would normally do, live their lives as always. They are observed doing their normal routine. On the other hand, randomized controlled trials use interventions (diet, exercise) to change some participants' behavior to see how it affects their health. Or, they may give certain treatments (a new type of chemotherapy, for example) to some participants to see how effectively it treats their breast cancer.

The following table is an overview for women who survive five years, but many go on to survive far longer than five years. You will see that the table does not divide survival rates by all of the substages, such as IA and IB. The rates for these substages are likely to be close to the rate for the overall stage.

Stage: 5-year Survival Rate

0 - 93 percent
I - 88 percent
IIA - 81 percent
IIB - 74 percent
IIIA - 67 percent
IIIB - 41 percent*
IIIC - 49 percent*
IV - 15 percent

*These numbers are correct as written (stage IIIB shows worse survival than stage IIIC).

I'm following the Action part of Komen's new motto: Less Talk, More Action. Following several breast cancer events (many of them 3 Days) I created a new business that focuses on improving health/wellness and reducing the risk of developing cancer in the first place. However, I recognize that cancer will still strike some even if they do all the 'right' things. That's why the charitable contribution component of the business is so important to me...and research doesn't come cheap.
