I am of more positive thinking here. I think our problems with cancer are due to misunderstanding what cancer is in the first place. Here, Thomas Seyfried can explain this much better than I ever could: https://www.youtube.com/watch?v=KusaU2taxow I think once we know where cancer comes from we can be much more effective at preventing it in the first place (proper diet) and treating it after the fact. With the current…

It's been a few years since I was as deep into this realm so I might be slightly off but; Cancers and Tumors mostly happen as a result of some errant mutation - there are limitless causes for such things and the best diet in the world can't save you from random biological chance or solar radiation. Everything comes with a risk and 98 times out of 100 your own defences will see this mutation happen and shut it down be…

A non-specific treatment that revs up the immune system increases the risk of autoimmune disease. It would have to be specific to the cancer AFAIK, so more of a treatment for an existing cancer than a preventative measure.

An enhanced immune system would functionally be a “cure for virus”. It’s conceivable we could find a technique that targets and ruptures any cancer cell, functionally becoming a “cure for cancer”.

Which could increase the risk for autoimmune disease. Current immunotherapy treatments for cancer that I'm aware of have to be carefully monitored so they don't kill the patient.

I wonder if this is affected by tissue types, e.g. bone.

I am not a biologist but I've known a few in my time; It is highly unlikely there will ever be a singular "cure for cancer" as cancer is a bit of a blanket term given to multiple diseases, however this is a seemingly reasonably good breakthrough in treatment - being able to destroy cancerous cells without exposing the patient to further harm via targeted radiation or harsh chemo drugs (basically targeted poisoning) f…

Or better yet find out how to prevent cancers since it's better to not be sick than to treat you once you are sick. Things like the HPV vaccine which in my province saw a 90% drop in just a few years. I think everyone should get it no questions asked which maybe they don't anymore? The Hepatitis B vaccine too since having the disease is a cause of liver cancer. But if all else fails it's also good to have a tools to…

HPV is a unique one because it's essentially a contagious cancer, and you're not vaccinating against cancer, you're vaccinating against the carrier (HPV). A really interesting cancer treatment that's very promising is customized vaccines that specifically target cancer cells for each individual's cancer!

Every single cancer treatment is about destroying cancer cells. Given the clickbait level of the headline it's clear that it is not worth clicking.

>Given the clickbait level of the headline That is not a clickbait headline, it's very descriptive of the contents of the article. Clickbait would be like "Crazy new cancer cure will literally punch cancer cells to death! You won't believe it!"

Title was changed.

The real question is always "but how good is it at killing non-cancer cells?" A bullet fired from a gun would be great at killing cancer cells too. Although in this case it seems like it's just an alternative to surgery, rather than a cancer cure? Just a way of vibrating cells in a certain location to death? Does anybody who actually understands medicine know if this is a great breakthrough or not?

I had the same question when reading this. They use the light only at places where cancerous cells were found plus some safety margin I guess. In that sense it's an alternative to surgery.

Essentially correct. They use near-infra red light, which can only penetrate about 3cm of skin, so this is not a complete replacement to surgery.

New modern chemotherapy (anti-body drug conjugates) are also similar to how it "adheres" to cancer cells, by binding to specific cell expression. It's not re-inventing this technology, just finding a new way to leverage it. The drug will also bind to normal cells, but by directing light to a specific area the goal is to minimize damage and side effects.

Near Infrared (NIR) is affected by tissue type. It's light, different densities of a substance, along with what that substance may be comprised, will influence the rate of absorption of the light by a substance and reduction in light penetration.
