Radiation therapist here. The most common exogenous factors we see strongly contributing to cancer development are: heavy smoking, heavy alcohol consumption, HPV, and high sun and exposure. Here’s common examples: I smoked a pack a day for 25 years. I drink 5-6 drinks a week. I do both of the above. (This one is far and away the biggest cause of preventable fatal cancer) I got HPV in my throat, and never knew until I got cancer. I tan or get prolonged sun exposure a couple times a week. Avoid these risks and you’ll skip everything you could possibly prevent on your own. The rest is luck. Just don’t eat cadmium or whatever. Also, quit vaping. We don’t know what it does to the human body, yet.

Reminder that this is usually the case for white people. People of color have better protection to sun rays. In fact, the recommended sun exposure may vary depending on your skin. For white people, it's around 15-45 minutes minimum in order to generate vitamin D (and higher doses of sun rays may prevent eyesight issues; there's evidence that show that children who spend 1-2 hours outside are less likely to develop eyesight problems), whereas black people may require a few more minutes of exposure to the sun. Also, another issue is vegetation and trees. If you're able to protect yourself from the sun with trees, you're able to be out for a longer period of time. This is an issue in car centric cities as there may not be green areas nearby, and sun exposure may be more harmful to all forms of life.

You can avoid carcinogens for your entire life and there is still a very real chance that some cell somewhere decides that it is having a bad day and decides to make that your problem. no amount of caution will ever reduce your odds of cancer to 0 (obviously there is merit in reducing your risk).

For the mold one, I am disappointed you didn’t mention how prevalent black mold is in buildings across the world. Obviously no one will purposely eat a ton of moldy food. But I myself have experienced living in an apartment infested with black mold and within 2 months I became extremely sick, constantly had respiratory issue, extreme brain fog especially when entering my bedroom (where the mold was most concentrated), mood disturbances and even developed asthma. I would cough up phlegm that would literally, no exaggeration, have spores inside it. When I saw that in the bathroom sink I couldn’t stop crying. When I saw how much black mold was in my AC unit alone I was terrified. Everyone I show the pictures to I have to give a warning because it’s that disturbing. And that common. I know so many other people who have experienced the same-this being NYC, which is supposably the best city in the world. There is very little tenant protection for this despite mold being a huge tenant’s rights violation in NYC. I am so lucky I was able to move out of my lease. Many people don’t have that option and have to live for years in toxic environments. There’s even a phenomenon called “Sick building syndrome” where people who feel extremely ill inside their apartment buildings feel better once they go outside. This is due to toxins such as black mold and water damage as well as a lack of airflow or light in many “modern” apartments, which in all seriousness rival tenement housing in terms of toxicity. Mold is a huge human rights issue that remains ignored in favor of landowner profit.

Also, if you have the Asian flush or cannot process alcohol normally (like red flushing + other side effects), acetaldehyde stays in your system far too long and in essence, drink for drink (vs normal process) increases your exposure to cancer :/ Important UPDATE: While the ALDH2 enzyme primarily targets acetaldehyde, it is also involved in detoxifying other aldehydes, including 4-HNE (associated with cancer, etc). So, individuals with the ALDH2 mutation may have a reduced capacity to metabolize and eliminate 4-HNE effectively. 4-HNE essentially comes from the peroxidation/consumption of Polyunsaturated Fatty Acids (PUFA). So we suck at alcohol, but we also suck at foods high in PUFA's. Lol.

There's a safer alternative in the form of shellite (aka 'white gas'), it has similar volatility to gasoline/petrol but minimal aromatics content. Not a good substance to put in engines however, the octane rating is around 60 so most engines will 'knock' if you use it as fuel. In some parts of Australia service stations only sell 'opal' fuel which is similarly a low aromatics petrol, albeit with an octane rating equal to normal fuel. This was introduced to combat the petrol sniffing epidemic, the aromatics in regular fuel are responsible for most of the intoxicating effect so sniffing Opal won't get you high.

In 2000 I was a 21 year old apprentice in an auto body shop. As the young apprentice I got the crappy jobs of cleaning stuff like paint guns. We use a strong industrial paint thinner for this that was "Not To Be Sold to Consumers". The rubber gloves we had in the shop were useless against thinners and just bulged up and broke within 60 seconds of exposure so all cleaning took place with bare hands. I spent hours with my hands soaked in these paint thinners that were a mix of acetone, toluene, benzine, methyl ethyl ketone, xylene and dozens of other highly volatile organic compounds. After 6 months of doing that the skin on my hands was thick, dried out and cracked. I started having nervous system issues, shaking hands, inability to sit still, high anxiety, loss of concentration. I didn't even realize this was what was happening until about a year or two after I left the job when all the symptoms went away after I was no longer being exposed to these chemicals. That was 24 years ago and I still don't have liver or kidney cancer but the chronic exposure only lasted for about 12 months.

My home town has massive agricultural fields called bogs for a mono-crop berry. Helicopters would drop pesticides and herbicides and we'd be informed to stay inside as it catches in the wind and fields are right next to, in front of, or behind most houses. They used round-up heavily for many years, not sure if they still do. But as a small town everyone also uses wells for drinking water. Additionally the cranberries are harvested every fall by flooding the bogs via pump houses that pull from the numerous ponds around town (berries float). After winter the water is emptied from bogs and pumped back into the ponds. In high school pretty much the entirely English department got cancer and librarian died of cancer too. I have friends from high school who got cancer and one had testicle removed shortly after graduation. My dad just finished 6 months of chemo for a blood cancer. Round up is no joke, especially chronic exposure to it..

It was however suggested that acrylamid is a reliable indicator for the formation of four specific heterocyclic amines that are among the most potent carcinogens known in certain animals, but again, it couldn't be shown that this is the case for humans - and furthermore, it was demonstrated that the mechanism of carcinogenicity (further metabolism by specific gut bacteria) does not apply to humans at all.

I am your #1 fan (and used to wash my hands with toluene to remove tar), but there are a number of misunderstandings in this otherwise great video.

In E and SE Asia, probably around one billion people chew it daily. It's the only thing that really competes with tobacco for mass cancer causation. 2 - AFLatoxin (not aLPHatoxin) is not in every mould, it is in a very specific one, Aspergillus flavus, which grows almost only on nuts and grains. A. flavus is unable to grow under 5 °C, so the many moulds that spoil food in fridges are basically guaranteed to be free from it. It is true that there are other, more obscure carcinogenic mycotoxins in, e.g., some strains of A. niger, but one shouldn't assume something as terrifying as aflatoxin is present in all mouldy food, some of which is eaten intentionally (think soy sauce and blue cheese). 3 - where are the nitrites?

[@mynamo12]

Soy sauce? Fermentation is not the same thing as food with mold.

I am on a pharmacy rotation through an oncology clinic right now, so a chemotherapy video would be very interesting to me. Can't wait for it! Thanks for the nod to cyclosporine and tylenol. Cyclosporine is used as an eyedrop for dry eyes branded as Restasis! I was hoping cyclophosphamide was going to make the cut in the video.

[@channelsurfer5348]

Me too.. im sure its cytotoxic.

I'm deeply shocked that League of Legends wasn't listed here

[@jacobtierney4419]

This combines two of these subjects! My college A-level chemistry lecturer used to work on testing peanut butter for aflatoxin. The used to scrub out with benzene to remove any residues.

[@jonesuniversity3104]

What a fun experiment. We shall have to try it.

[@andya7283]

Vinyl Chloride was what was in those tanker that derailed in East palestine Ohio. Something like 6 full rail cars were left just to burn because of fear of an explosion not to mention all of the treated wood rail planks that you also spoke of being treated with a carcinogenic.

I won't completely avoid carcinogens, but I'll do asbestos I can.

[@expertoflizardcorrugation3967]

Asbestos is such a fun word too, such a shame that it has to be so terrible.

Can you do a video on poisons we use in our daily lives like prallethrin and such? I wish I knew better so that I could minimize the poison intake in my daily life. Thank you for your amazing videos anyways. You got yourself a new subscriber.

[@That_Chemist]

Apparently the pyrethroids are non-toxic to humans - they operate on the insect nervous system in a way that doesnt affect ours

[@peterhrtg]

Outstanding presentation; a LOT of work - thank you! Way back, I spent some time as a bench chemist. Mainly (organo-) heavy metals, but also benzene and petroleum products, plus HF. I now have multiple myeloma. So, be VERY careful out there, folks… 🥺

I didn't understand 90% of this video, but I think my main takeaways are don't smoke and make sure your shampoo isn't releasing formaldehyde

Chloride groups in Sucralose or other artificial sweeteners attach to stray sodium ions in the body when consumed creating sodium chloride ( NaCl ). We don’t know why specifically this happens with sweeteners, leading theory is the chlorides in these molecules are substantially more negative than the entire molecule itself and effectively break off from the whole molecule and attach stray sodium ions. Coincidentally If you have hyponatremia and you consume Sucralose you can get very sick as the chloride ions on the sugar molecule stay as chloride, effectively giving you acute chloride posioning.

In regards to people washing their hands with benzine, when I would help my dad as a kid and we’d get grease on our hands we would wash our hands with a bit of gasoline to get it off ☠️

Agh. As a chemist working in an environmental lab and frequently running a GC/MS that's calibrated (by yours truly) to detect many of these semivolatile carcinogens (and more)...this hurts. I mean, I knew I was fucked, but just hearing this from another chemist really drives it home. Thankfully the fume hoods work when I'm making the calibration mixes and I always replace the GC vial caps of the calibration standards immediately after they're injected, but damn. I'm probably being exposed below occupational exposure limits, but in non-zero amounts. Can't wait to hit my 40s/50s/60s and develop a rare as fuck cancer that's untreatable/late-stage. Good times.

It’s not so bad dude. One must not squint at what cannot be seen. You can’t see the future. Get check ups 1-2 times a year if you’re worried. And don’t think cancer upon yourself iykwim placebo is a real thing.

[@Whateverister]

Man I feel you, in the lab i work in there's a working GC and no fumehood. Shit's tough, been here for almost two years and seeing this video, I gotta start thinking of other options😂😂.

Very much appreciated. It's about time we had this in a digestible format

Since we're on the topic of carcinogens, and as you're as much of a safety stickler as me, you might appreciate a recent story of mine. I was doing some engine work on a jet and grabbed a squeeze bottle labeled as isopropyl alcohol, to wipe out the bottom of the engine cowling so I have a clean place to sit. I dropped the cowling down and got to squeezing the bottle and was stung with the spiciest smelling iso I had ever smelled. Later that work week I discovered we have jugs of MEK in basically the same container as iso, so somebody had refilled the iso squeeze bottle with MEK. Burned my nostrils a good little bit that day.

[@That_Chemist]

Yikes!

[@pizzablender]

I had a bottle of MEK-based nail polish remover. Maybe they found acetone too aggressive? These days it seems to be ethyl acetate.

I worked for a family friend’s powder coating company for a few weeks during peak season to get him out of a labor shortage. I was about 18 and didn’t know any better. Part of the preparation process was that the recently manufactured metal parts needed to be cleaned and washed and dried prior to being sprayed in an electrostatic powder booth. To do this, a wash station was used which considered of a large 50L plastic container with a hole cut in its side, which acted as a crude solvent bath. The solvent was a 1:1:1 industrial solution of toluene ethanol and methanol. The PPE provided was a pair of standard rubber dishwashing gloves. That’s it. After washing for a couple of hours, the Vapor would mix with sweat and condense inside the gloves causing my hands to be very cold and “wet” which caused the gloves to stick and slip and slide and to generally be uncomfortable. The coldness also caused less dexterity in my fingers so I did what most can-do kids at that age would do and simply removed the gloves. After about a week of 7-8 hour days with hands spend in the solvent bath, and being very attracted to the sweet smelling Vapor (which was not vented in any way) I started to noticed very my hands becoming cracked and shrivelled even on the weekend. The solvent had pulled almost all the oil out of my skin and my skin had started to break around my nails. I was also not provided any PPE for my lungs to protect against the powder, which was (I found out later) about 35-40% lead. After realising this and seeing many other things that raised red flags such as people regularly smoking meters from the wash station, I decided it was not appropriate for me to continue to work there. To the best of my knowledge there has been no lasting effects, but at the time I did wonder if there could have been some trace amounts of benzine in the solvent from the manufacturing process. I guess time will tell :/

[@zachross3541]

Thanks for the info!! Had to hit my vape to calm myself down reading about these carcinogens😅 I don’t ever want to be exposed to those
