Salvatore Iaconesi's essay on his decision to post his medical records on the Internet in hopes of finding a crowd-sourced cure for his brain tumor has sparked a lively conversation on CNN.com.

Readers raised a lot of thoughtful questions about his methods and what he was trying to accomplish, so Iaconesi jumped into the comments to respond. Many of the questions were too long to duplicate here, so we included excerpts and a link to the full comments. Some questions and responses have been edited for clarity.

You can read his full essay and participate in the discussion on CNN's opinion page.

1) Can this help a lot of people?

momza: His idea does not scale well. As long as he is the only one, he has a good chance that an idle doctor stumbles upon his files. If all the people publish their records, the chances will be extremely low. (Read the full comment)

Iaconesi: Hello. Yes, it does not scale if we start from the assumption that I'm doing it for myself, and that what I'm doing is to find the best doctor.

But this is not the way I would want it to be. What I'm really looking for is to suggest a vision in which this process happens and its results (and the process itself) is shared/shareable and replicated by everyone.

Imagine that the results of this remain accessible. If you, tomorrow, have to go through cancer, you will be able to benefit from all this work already done, with contacts, different strategies combined in critical, harmonious ways, documented testimonies, ways to access the various services etc.

What I am also asking is to go beyond the idea of eHealth, and to not limit this whole thing to an "administrative" or, even worse, "bureaucratic" process, because this is really harmful to people, both the "diseased" ones and the rest of the members of society.

A "cure" should really confront with the whole human being. From what we're understanding now, it would have benefits at multiple levels, including financial and technical ones (and, obviously, at the level of health and well being)

2) How do you pay for the treatment?

Baba Louie: The one thing the guy doesn't mention is insurance. ... When average Americans get diagnosed, they have to think of how they can get effective treatment without losing their house because they have lousy insurance policies and Medicare, none of which pay for the advanced treatments that can keep you alive.

Iaconesi: Ahhh, Baba, that is an incredible issue! In Italy, for example, we have a very good welfare system for health. Hospitals and infrastructures are not very good, but doctors are really excellent and many things are really covered by the national health system. So this can be a somewhat lesser problem for us.

But as soon as you want to access something that is not "standard" (even a simple blood test of a specific kind, to analyze the presence of cancer markers) costs rise exponentially. This is another thing we're confronting -- also trying to imagine ways to help people (including me) to integrate in the "cure" the possibility to raise money to actually perform it.

3) Can't advice from non-doctors do more harm than good?

Tim: Please seek qualified, legitimate sources for your treatment. ... While one may want to believe that "spiritual healers" or "artists" can contribute to your treatment, the truth is that they will not, and they may actually be harmful by distracting from legitimate treatments. (Read the full comment)

Iaconesi: Dear Tim, actually "ordinary people" have been incredibly helpful, through their testimonies, experiences and evaluations. Where clinical trials often are performed with as few as 30 people, I have been able to compare the documented testimonies of hundreds of people. And this is just one example of the ways in which this kind of process has been really helpful and productive.

I won't even go, for now, into the enormous implications at a psychological, social and cultural level which I myself and many, many people are perceiving. But I do agree: If I eventually have to have a surgery performed, it will be by a professional doctor :)

4) Will opening the records do any good?

jamesrav: I'd be interested to know how making it 'open' actually benefited his condition versus keeping it 'closed'. I'm thinking the specialist who gave him his results and options knew the very best that medicine could offer for what he has. (Read the full comment)

Iaconesi: Great point. And that's one thing I'm really caring about: combining things in effective ways. To do this, I explicitly ask people (doctors, researchers, regular people... ) who contribute, to compare their approaches, also critically, and to try to understand how and if they should/could be combined, and to what extent.

Even in this scenario doubts remain, obviously. But at least you can benefit from a wider set of competences, technologies, strategies, philosophies and you can have an active role in the decisions which will affect your health.

Also because everyone involved will dedicate energies to make sure that they keep you informed and in the loop, making sure that you are actually able to understand what they're talking about, the implications and side effects, the dangers and problems.

5) Can cancer treatment be crowd-sourced?

Joe Michaels: It would be wonderful if a crowd-sourcing site existed for cancer. Options for treatment (offered by physicians / treatment facilities) could / should include research data on outcomes, side effects, and so on. This would greatly simplify a mystifying experience for many patients.
