“Does Apple’s Steve Jobs have cancer again?” Henry Blodget asks for SIlicon Alley Insider.

“In the photos we saw of yesterday’s event, Steve appeared dangerously thin. The most likely explanation, we think, is that Steve permanently changed his diet after his bout with cancer a few years ago. Given that Steve did not believe that cancer needed to be disclosed publicly until after the fact, however, it also seems possible that the weight loss could be an indication that Steve’s cancer has reappeared,” Blodget writes.

“We hope it hasn’t. As we argued here, however, we believe that Steve’s cancer should have been disclosed earlier, and–if it ever recurs–should immediately be disclosed. It seems inappropriate to ask Apple to issue a statement confirming that Steve is in perfect health, but we know such a statement would make some of concerned Apple and Steve fans feel better,” Blodget writes.

Valleywag’s Nicholas Carlson writes, “Doctors diagnosed Apple CEO Steve Jobs with pancreatic cancer in October 2003. Jobs hid the news from Apple shareholders until July 2004 — after he’d explored all other alternatives to surgery, and had to schedule time away from the office to go under the knife. People watching the imperiously slim presenter at the WWDC today are finding it hard to look at Job’s frailer-than-ever frame and not wonder if he’s still suffering.”

When we first saw Jobs we worried, too. We’ve since somehow convinced ourselves that “everything’s okay,” (classic denial, perhaps), but, seriously, we’d really like for Apple to tell us publicly about Steve’s “robust health” again, or at least see the results of someone feeding the man, or hear that he just won a marathon somewhere. There’s “thin” and there’s “too thin.” Steve is “too thin” for a man with a past cancer history who has millions of shareholders invested in Apple; many who have invested in the company mostly because of his presence.

Even Drudge this morning has a headline “Concern over APPLE Steve Jobs’s physical appearance…” pointing to an AP photo gallery of Jobs on stage yesterday.

Apple need to address this issue again.
