Welcome back to Baby Breakerdom! This week's quest to uncover budding Rule Breakers finds a new rubric for cancer research and a dashing investment for two of Silicon Valley's finest.

First up this week is Rubicor Medical, which is devising a series of devices that may aid in the early detection of breast cancer. One device, the Ovation, is minimally invasive yet capable of collecting large samplings of breast abnormalities, reports VentureWire.

Color me intrigued. Breast cancer is very treatable if detected early. In fact, the five-year survival rate for sufferers who catch the disease early stands between 85% and 95%. Ovation could help boost that rate even further by making testing easier. To me, this is an idea reminiscent of the minimally invasive heart-surgery technique pioneered by Motley Fool Rule Breakers selection Intuitive Surgical (NASDAQ:ISRG).

Still, I wish superior investors were lining up to fund this infant rebel. Instead, $20 million is coming from former dot-com flierSafeguard Scientifics (NYSE:SFE) and $5 million from Silicon Valley's ITX International Equity. Rubicor's founders paid a final $5 million into the company to complete the round. Will that remarkable show of faith translate into meaningful revenue gains? Considering the size of the scourge it hopes to address, there ought to be plenty of opportunity.

The same might be said for Dash, given its backers. Legendary VC sluggers Kleiner Perkins Caulfield & Byers and Sequoia Capital have teamed up to fund the firm. Details of the financing weren't revealed, but it's interesting to note that legendary Kleiner partner John Doerr was quoted in the press release announcing the deal.

Still, I have mixed feelings. Dash plans to transform a vehicle dashboard into a portal of Web-connected information. What? Cell phones aren't enough? Apparently not. Dash says that, on the whole, Americans are frequently stuck in traffic and that 3.7 billion hours of potential productivity were lost during 2003 as a result.

Good point. My wife and I drive our kids to school all the time, and the traffic is miserable. I'd no doubt benefit from having an in-car system to keep me apprised of traffic conditions, email, and news that I'd want to write about later in the day. But couldn't such a service also become like crack? Aren't we drivers distracted enough?

Maybe, but the possibility of an addictive product appears to have attracted some big-league talent to Dash, including former executives of XM Satellite Radio (NASDAQ:XMSR), TiVo (NASDAQ:TIVO), and Real Networks (NASDAQ:RNWK), among others. It makes me wonder whether Dash, too, is bound for the NasdaqStock Market. Check back in a year.

That's all for this week. See you back here next Friday, when we continue the quest to find the next ultimate growth stock.
