What are the most common warning signs of cancer?

@lactose many times none. Or pain, a lump, it can be anything.

@Ecstatic_Hamster I think you should be able to do it if you click the three little dots next to "Reply" and "Quote" on the original post! Otherwise let me know and I will edit it.

@Ecstatic_Hamster The information about THC is very surprising and unintuitive to me. Could you point to some of the studies or papers that led you to this conclusion?

@brad it is a little tough to show more than anecdotal evidence but I will try.

this study tries to "sell" these tiny vesicles as a delivery mechanism to cancer, but it uses THC and CBD
this is kind of anecdotal on CBD

CBD increases effectiveness of breast cancer therapiesTHC in HER2-positive breast cancer
https://pubmed.ncbi.nlm.nih.gov/30733293/The cannabinoid Δ9-tetrahydrocannabinol (THC) disrupts HER2-CB2R complexes by selectively binding to CB2R, which leads to (i) the inactivation of HER2 through disruption of HER2-HER2 homodimers, and (ii) the subsequent degradation of HER2 by the proteasome via the E3 ligase c-CBL. This in turn triggers antitumor responses in vitro and in vivo. Selective targeting of CB2R transmembrane region 5 mimicked THC effects. Together, these findings define HER2-CB2R heteromers as new potential targets for antitumor therapies and biomarkers with prognostic value in HER2-positive breast cancer
and a review article
https://pubmed.ncbi.nlm.nih.gov/29390896/
the endocannabinoid-degrading enzymes fatty acid amide hydrolase and monoacylglycerol lipase, lipid transport proteins of the fatty acid binding protein family, additional cannabinoid-activated G protein-coupled receptors, members of the transient receptor potential family as well as peroxisome proliferator-activated receptors have been considered as targets of antitumoral cannabinoid activity. Therefore, this review focused on the antitumorigenic effects induced upon modulation of this extended endocannabinoid network. -

Additionally, in in vivo studies in severe combined immunodeficient mice, there was significant inhibition of the subcutaneous tumor growth and lung metastasis of A549 cells in THC-treated animals as compared to vehicle-treated controls. Tumor samples from THC-treated animals revealed antiproliferative and antiangiogenic effects of THC.https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0228909
The tumor samples were classified according to the level of expression of CB1, CB2, or both. Patients with high expression levels of CB1, CB2, and CB1/CB2 showed increased survival reaching significance for CB1 and CB1/CB2 (p = 0.035 and 0.025, respectively). Both cannabinoid agonists inhibited the proliferation and expression of EGFR in lung cancer cells, and CBD potentiated the effect of THC. THC and CBD alone or in combination restored the epithelial phenotype, as evidenced by increased expression of CDH1 and reduced expression of CDH2 and VIM, as well as by fluorescence analysis of cellular cytoskeleton. Finally, both cannabinoids reduced the in vitro migration of the three lung cancer cells lines used.Conclusions
The expression levels of CB1 and CB2 have a potential use as markers of survival in patients with NSCLC. THC and CBD inhibited the proliferation and expression of EGFR in the lung cancer cells studied. Finally, the THC/CBD combination restored the epithelial phenotype in vitro. -
A good review article on how cannabis inhibits or reverses cancer
https://www.mdpi.com/1422-0067/21/3/747Breast, brain, pancreatic, prostate, blood…virtually all cancers.
A couple of interesting observations I’ll make from this review.
An increasing number of reports highlighted the role of cannabinoids in cancer spreading, specifically in invasion, angiogenesis, migration, and metastasis mechanism [5,6,7,8,9,10]. Likely, these mechanisms can be triggered through the modulation of different pathways.
As a consequence, a down-regulation of the proangiogenic factors vascular endothelial growth factor (VEGF), placental growth factor (PlGF), and angiopoietin-2 (Ang-2) occurs [8]. Moreover, cannabinoids inhibit angiogenesis and invasion,
Another interesting observation derives from glioma and breast cancer, where the treatment with CBD or the CB2 agonist O-1663 exerts the inhibitory effect on cancer cell invasion through a down-regulation of Id-1 and Sox-2 protein expression [6].
Encouraging results were obtained in regards to the FAAH inhibitors, AA-5HT (N-arachidonoyl-serotonin) and URB597. Used alone, AA-5HT exerts an antiproliferative effect in glioma and thyroid cancer [5].
Moreover, in azoxymethane (AOM)-induced colon cancer murine models it reduces the onset of aberrant crypt foci, probably in a CB1-dependent manner [16]. URB597 showed a potent antiproliferative effect used in combination with AEA (or Met-F-AEA) in neuroblastoma, lung, and colon cancer, or combination with PEA in melanoma cancer cells [5]. In lung cancer, both AA-5HT and URB597 contrast tumor invasion through TIMP-1 upregulation, likely in a CB2- and TRPV1-dependent way [17]. The MAGL inhibitor JZL184, inhibiting proliferation and tumor cell invasion, induces apoptosis in colon and prostate cancer [18,19]. Interestingly, URB602, another MAGL inhibitor, reduces AOM-induced preneoplastic lesions and reduces tumor volume in vivo in colorectal cancer (CRC) models. Moreover, URB602 inhibits angiogenesis down-regulating vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor 2 (FGF-2) [20].
2.2. Cannabinoids Affect non-CB1/CB2 ReceptorsBeyond CB1 and CB2 receptors, it is well known that other non-CB receptors are involved in antitumor action of cannabinoids, representing another interesting target for therapeutic intervention. TRPVs are non-selective cation channels found to be a key player in cannabinoids-induced anticancer effects.

@eugene fasting by stopping the consumption of food can be useful so long as you consume salty coconut water and fruit juice to preserve electrolytes and lower cortisol somewhat. And I wouldn’t do it more than 36 hours at a time.
It has one benefit, which is lowering endotoxins.
I think a diet primarily consisting of non-animal protein is very important. Keeping methionine below 1g per day is useful to stop cancer from spreading.
I think Dr. Peat never explored methionine to a great degree, at least I never heard him talk much about it, but methionine from animal protein is a factor that limits life and that promotes cancer. It is why a keto diet is a bad bad idea in cancer.
On the contrary - he talked about limiting methionine quite a lot in interviews.
https://bioenergetic.life/?q=methionine+
https://raypeat2.com/articles/articles/gelatin.shtml
"It happens that gelatin is a protein which contains no tryptophan, and only small amounts of cysteine, methionine, and histidine. Using gelatin as a major dietary protein is an easy way to restrict the amino acids that are associated with many of the problems of aging."
Dr. Peat said;
"Any stage of healing wound can be identical to cancer. "https://bioenergetic.life/clips/d96b2?t=4352&c=92
I wonder what this means for the diagnosis of cancer? Is it a healing wound or is it cancer?
-
@Peatly I mean this, that Dr. Peat talked about restricting methionine a bit, but he promoted dairy and ate that a lot himself, which is higher in methionine and he never advocated a plant based diet primarily.
I have found that many times, wounds can turn into cancer sites. I have found this through listening to many people’s account of getting cancer, and in some cases, an injury or wound preceded the cancer. I don’t know if that’s what Dr. Peat meant, but it is something I observe quite often.

Probably a decrease in metabolism. Cold hands and feet, mental problems. I suffer from these, felt like I was on the verge of death today but I saw @haidut study on cancer treatment using b1 b3 b7 and aspirin so decided to take all of those today in doses of 1g, 500mg, 10mg and 600mg and it had profound effects on my mental clarity and energy to the point where I felt more normal again.
Going to up the dose tomorrow as I experienced no stomach upset with the aspirin which was my main worry. Seems to fair well when taken shortly after the B vitamins. Off topic but I wanted to share

Yes, Dr. Peat did drink a lot of milk but he restricted his meat consumption for more gelatinous cuts. I think he would say that the calcium in milk was protective as inadequate calcium intake is a risk factor for some types of cancers.
The thing about wounds that turn into cancer, can we be sure that they were really cancer? In one interview he said benign tumours were being reclassified as cancer. So, what was just a harmless lump, 50 years ago, is now cancer.
“An article in JAMA about 40 years ago looked at the evidence of how the pathology methods of analyzing the properties of the cytoplasm nucleus ratio and the matter of disorganization and invasion and so on and in this article it was demonstrated that a healing wound if it's biopsied will show all of the properties that are used by the pathologist to identify cancer so that what is defined as cancer has become more inclusive and if you happen to have an injury that gets biopsied it'll be called cancer because it has the properties of of rapid growth uh invasive appearance and so on.” Ray Peat

@Ecstatic_Hamster LOL this has to be a joke.

“About 40 years ago, three different doctors diagnosed, told me that I should have a biopsy on three different things. And since I had already been studying what doctors do and know about cancer, I ignored them and increased my thyroid and used a little nutritional addition like extra vitamin A and folic acid. I put some progesterone and DHEA on the area. And so far, that's 40 years ago, and none of them have persisted.” Ray Peat

even the little methionine in gelatin?

Seems like all the roads point to vegetarianism in many ways.

A blood test to look for fragments of DNA in the bloodstream
“She was offered a blood test, also described as a "liquid biopsy" which looks for fragments of DNA which have broken off tumours and are in the bloodstream.
This so-called "circulating tumour DNA" revealed that Kat's cancer growth was being driven by a mutation in the ALK gene.”
I won't state the obvious
This story was published hours before the announcement that the other Kate has cancer.

I was told by a nurse that there are a lot of cancer deaths in men lately. When I asked what type she said prostate. I guess the screening trial is "working"
