Cancer

Cancer is uncontrolled cell growth with genetic and metabolic features. Many cancer cells ferment glucose to lactate even when oxygen is present (Otto Warburg). Here that respiratory failure is the center of the story: a tissue field of low CO2, high stress chemistry, and incomplete oxidation, not only a stack of DNA accidents.

Prevention terrain and treatment of established cancer are different jobs. Established disease needs oncology. The metabolic field is the terrain that makes cancer more likely and that supportive care tries to shift.

The energy field

Cancer cells use glucose and glutamine mainly to build tissue and burn fats for energy, and the growth-stimulating effect of the "essential fatty acids" means depriving a tumor of those fats slows it. In cachexia, thyroid hormone, especially with progesterone, stimulates protein synthesis and prevents lactate formation or speeds its oxidation, keeping it out of the Cori cycle. A model built on age-related thymic decline in T cell output fit cancer incidence across many cancer types better than a mutation-accumulation model.

Healthy cells finish oxidizing fuel in mitochondria. Cancer-prone tissue leans on glycolysis, raises lactate, and loses the protective chemistry of CO₂. Estrogen, PUFA, free fatty acids, serotonin, and endotoxin push that same inefficient path in non-tumor tissue under chronic stress. Cancer is an extreme of a field the body can enter before a tumor is named. See Warburg effect, Mitochondria, Lactic acid, CO2.

Low serum bicarbonate (the clinical proxy for low CO₂) tracks worse cancer outcomes directly. In two independent cohorts of localized non-small-cell lung cancer treated with stereotactic body radiation, bicarbonate below 26 mEq/L before treatment predicted primary tumor recurrence. Georgi Dinkov (Haidut) reports the same pattern anecdotally in bloodwork sent to him by cancer patients: every case in that personal sample ran below 20 mEq/L bicarbonate, well under the ~20-32 mEq/L range described there as typical, though this is an unquantified personal sample, not a study.

In mice with metastatic breast cancer, baking soda in the drinking water raised the pH around tumors, cut the number and size of metastases and lengthened survival, without slowing growth of the primary tumor or lowering circulating tumor cells.

Aspirin stimulates mitochondrial respiration and lowers prostaglandins; it appears in cancer-supportive correspondence at multi-gram daily totals with vitamin K and food, never as a substitute for medical care. See Aspirin.

In long-term follow-up of old heart-prevention trials, daily aspirin for several years lowered both new cases of and deaths from colorectal cancer, with the gap appearing only after many years. Smaller trials found fewer recurrent adenomas, and in cohorts the protection was confined to tumors high in COX-2; see aspirin and colorectal adenomas.

Hormones and fats

Unopposed estrogen creates aging chemistry: leakiness, poor oxidation, and growth under deprivation. Progesterone opposes that set. Polyunsaturated fats in membranes and free fatty acids impair cytochrome oxidase and feed inflammatory eicosanoids. Lower seed oils and restore progesterone-thyroid tone is one preventive arc, not a cure claim. See Estrogen, Progesterone, PUFA, Thyroid.

In one lab's cell and mouse study of triple-negative breast cancer, a type that lacks the usual hormone receptors, progesterone slowed tumor cell growth and blocked spread to the brain through a progesterone receptor on the cell surface. See Progesterone.

A meta-analysis of cohort studies found higher dietary carbohydrate intake associated with lower breast cancer incidence, mortality, and recurrence, with dietary fiber carrying the strongest effect (a 3% drop in incidence per 10 g/d increment); dietary sugar showed only a marginal positive association with incidence, and whole grain a marginal positive association with mortality despite a marginal negative one with incidence.

Restoring pyruvate oxidation: dichloroacetate

Dichloroacetate (DCA) inhibits the kinase that normally suppresses pyruvate dehydrogenase, pushing glucose-derived pyruvate back into full mitochondrial oxidation instead of lactic acid, directly reversing the Warburg pattern above. In a published case report, a medullary thyroid carcinoma patient who had relapsed with widespread disease after exhausting other chemotherapy saw his calcitonin tumor marker fall from 38,611 pg/mL to 2,000 pg/mL within about 4 months of starting DCA, with a follow-up PET scan showing marked tumor reduction; the case is a single report calling for further study, not established treatment, and human trials of DCA elsewhere have shown limited efficacy and dose-limiting neuropathy. See Dichloroacetate.

Cysteine dependence and ferroptosis

Cancer cells, including cancer stem cells marked by the CD44 variant isoform, depend heavily on the xCT/SLC7A11 transporter to import cystine (which becomes cysteine, the rate-limiting building block of glutathione) to buffer oxidative stress from their altered metabolism. Blocking or genetically disrupting this transporter depletes intracellular cysteine, collapses glutathione synthesis, and triggers ferroptosis, an iron-dependent form of cell death driven by lipid peroxide accumulation, selectively in cells that had come to depend on the pathway.

Practice

Keep oxidation high: thyroid status, carbohydrate with cofactors, warmth, sleep. Lower PUFA and endotoxin. Use aspirin and vitamin K only with clear eyes about bleeding risk and medical context. Do not starve sugar as a symbolic anti-cancer act; free fatty acids and stress hormones can worsen the Warburg field. Acute cancer care is clinical. See Harm reduction, Sugar, Endotoxin, How to heal your metabolism.

Intravenous vitamin C

An NCI Best Case Series-style report of three advanced cancers (renal cell with pulmonary cannonball metastases; muscle-invasive bladder cancer; diffuse large B-cell lymphoma) described unexpectedly long survival after high-dose intravenous vitamin C, with histopathology reviewed at NIH. The renal case used 65 g twice per week for about 10 months after declining conventional therapy, plus N-acetylcysteine, niacinamide, whole thyroid extract, and thymus protein; chest films cleared except for one possible scar. The series does not prove vitamin C caused the outcomes and notes co-interventions and rare spontaneous regression as alternatives.

Cameron and Pauling reported matched historical cohorts where terminal patients given about 10 g/day ascorbate (often intravenous for about 10 days, then oral) lived longer than similar patients without ascorbate (mean survival more than 4.2 times longer in the 1976 analysis; about 300 days greater mean survival in the 1978 reevaluation). Those studies were not randomized. Double-blind oral vitamin C trials later found no benefit, and oral dosing does not reach the plasma levels of intravenous infusions. A Scottish hospital data-bank analysis of incurable cancer found median survival 343 days with ascorbate supplementation versus 180 days without (observational). See Vitamin C.

A randomized trial (36 patients) added high-dose IV vitamin C (pharmacological ascorbate) to standard chemotherapy (gemcitabine + nab-paclitaxel) for stage IV pancreatic cancer. Overall survival rose from 8.3 to 16 months and progression-free survival from 3.9 to 6.2 months, with no added toxicity.

Ketone bodies and lactate, both elevated on low-carbohydrate and ketogenic diets, directly fuel tumor growth and metastasis in mouse models; a 2024 Columbia study found ketogenic diets suppressed primary tumor growth but increased lung metastases via the pro-metastatic gene BACH1.

Warburg effect

The Warburg effect describes how many cancer cells ferment glucose to lactate even when oxygen is present. The original account describes a defect of respiration: the cell fails to complete oxidation to CO2 and ATP in mitochondria, and falls back on glycolysis. In the 1926 measurements, tumor tissue took up an average of 70 mg glucose per 100 cc of blood and returned 46 mg of lactic acid, meaning about 66% of the glucose consumed was fermented rather than respired.

For Peat, it is the metabolic signature of stress chemistry in general: high lactate, low CO₂, impaired cytochrome oxidase, free fatty acids and PUFA interfering with respiration, estrogen and serotonin pushing the same inefficient path. Cancer is an extreme of a field the rest of the body can enter under chronic stress.

Respiration first

Healthy tissue takes glucose (or other fuel) through mitochondria, makes CO₂ and water, and keeps lactate low when oxygen is available. Warburg cells keep glycolysis loud and mitochondria quiet. Agents that restore respiration and lower inflammatory and estrogenic stress move the field away from that state. Agents that block respiration or raise PUFA and stress hormones move it toward fermentation. See Mitochondria, CO2, Lactic acid, Cancer.

Aspirin, thyroid, sugar with cofactors, progesterone, and lower seed-oil load appear in the same anti-Warburg practical set because they support glucose oxidation and lower the stress signals that lock fermentation in. See Aspirin, Thyroid, Progesterone, PUFA.

Sugar restriction

"Warburg effect" names a defect of respiration. Starving a person of sugar does not automatically restore respiration; it can raise free fatty acids and stress hormones that further injure mitochondria. The goal is competent oxidation. See Sugar, Free fatty acids, Randle cycle.
