DNA (family history) is not destiny.

vitamin A

  2. prostate cancer

Carrots and yellow veggies: carotene gets converted to vitamin A.

adiponectin vs. pancreatic cancer

be slim and avoid diabetes


α-ketoglutarate (AKG) can inhibit carcinogenesis induced by oncometabolites or hypoxia by activating enzymes from the 2-OGDD family (2-oxoglutarate-dependent dioxygenases). Exogenous AKG exhibited anti-tumour activity by inhibition of angiogenesis in hypoxic conditions. The antiproliferative effect of AKG has been demonstrated on three cancer cell lines: Caco-2, HT-29, and LS-180. Depending on the type of cancer, AKG could affect tumour cells by reversing their metabolic response to hypoxia or pseudohypoxia.

AMPK, more, more – see the Longevity post

  1. colon cancer
  2. liver cancer

AMPK Promotes p53 Acetylation via Phosphorylation and Inactivation of SIRT1 in Liver Cancer Cells

  1. lung cancer
  2. melanoma
  3. prostate cancer

AMPK activity opposes tumor development and that its loss fosters tumor progression in part by regulating cellular metabolic pathways that support cell growth and proliferation. AMPK is activated in response to a shortage of energy. AMPK activity opposes tumor development and progression in part by regulating inflammation and metabolism.

autophagy (see autophagy in this Longevity post)

By preventing the toxic accumulation of damaged protein and organelles, particularly mitochondria, autophagy limits oxidative stress, chronic tissue damage, and oncogenic signaling, which suppresses cancer initiation.

Autophagy is an integral part of the DNA damage response.

Autophagy disposes of senescent cells for less chance of colon cancer.

Mutant mice with heterozygous disruption of beclin 1 have decreased autophagy, are more prone to the development of spontaneous tumors including lymphomas, lung carcinomas, hepatocellular carcinomas, and mammary precancerous lesions, and undergo accelerated hepatitis B virus-induced carcinogenesis.

Versus brain cancer:

Anti-brain cancer effects of cannabis shown in vitro.

Anti-brain cancer effects of cannabis shown in mice.

Cannabis may promote autophagy in the brain (anti-cancer).

But, unfortunately, the one human test cannabis for brain cancer failed.

Chronic disruption of the normal circadian rhythm tips the balance between tumor-suppressive and tumor-progressive gene expression to favor tumor growth.

versus breast cancer: avoid eating at night

  1. brain cancer

A dysfunctional circadian rhythm accelerates tumor progression in mice.

A functional circadian rhythm includes time-restricted feeding (modulating mTOR and AMPK helps prevent cancer)

Exercise is also a zeitgeber, so vigorous exercise is best early-to-midday

This ties in with the circadian rhythm as discussed in the longevity post. I credit improved circadian rhythm (including not eating anything past 1pm, and wearing sunglasses at night) for finally beating my multi-year battle with skin cancer.

better than aspirin, ibuprofen, or oxaliplatin

works via downregulation of telomerase – causing induction of apoptosis

consuming curcumin with black pepper may be necessary for the above benefits

consuming curcumin with turmeric may also help

antioxidants help – best from diet, not pills

supported by a secondary analysis of a randomized clinical trial with 25,871 patients.

Shown by the Lappe cohort in a four year, double-blind, placebo-controlled trial of vitamin D and calcium supplementation.

In a study of  25,000 men and women, those who were randomly assigned to take 2,000 international units (IU) of vitamin D each day for an average of 5.3 years were nearly 20% less likely than those who received a placebo to have an advanced cancer.

:A moderate intake of plant and marine Ω-3 in the context of the traditional Mediterranean diet (low in saturated and Ω-6 fatty acids but high in plant monounsaturated fat) appears to be the best approach to reduce the risk of both cardiovascular diseases and cancers, in particular breast cancer. A ratio of 2.5/1 Ω-6/Ω-3 reduced rectal cell proliferation in patients with colorectal cancer. The lower Ω-6/Ω-3 ratio in women with breast cancer was associated with decreased risk.

a whole foods plantbased (vegan) diet:

A plant-base diet is especially important for those at high risk for disease.

Shown by 61,556 British meat eaters and vegetarians

Shown by this meta-analysis of 26 published studies

shown by the best available evidence we have right now

Shown by the 2007 report of the World Cancer Research Fund/American Institute for Cancer Research

Choose carefully, combine many, and include cruciferous and raw.

A plant-based diet provides a variety of bioactive cancer fighting compounds.

A plant-based diet makes for better gut microbes which results in short-chain fatty acids acetate, propionate and butyrate.

A plant-based diet works via magnesium – from green leafy veggies and grains.

A plant-based diet also provides apigenin. carotenoids (lycopene, lutein, zeaxanthin, fucoxanthin) (vs. gastric cancer also).

Radish sprouts may be more potently anti-cancer than broccoli sprouts. The addition of radish, rocket and rape sprouts to broccoli sprouts could promote the hydrolysis of the glucoraphanin to anticancer effective sulforaphane to 2.03, 2.32 and 1.95-fold, respectively, compared to single broccoli sprouts. Meanwhile, the formation of non-bioactive sulforaphane nitrile in these three groups decreased greatly.

more anti-cancer: here, here, here, here, and in GreenMedinfo’s cancer database

Cancer prevention is best not considered as a war which can undermine prevention via behavioral changes. Why are not old and fat mice not studied?

What is lacking here is a large scale comparison of anti-cancer substances and lifestyles. The reason is that such a study has never been done, and would be incredibly difficult. Having reviewed the mechanisms behind much of what is linked to here, I believe the most potent anti-cancer things are: calorie restriction, broccoli sprouts, turmeric, and a robust circadian rhythm. It was the circadian rhythm-enhancing lifestyle that, I feel, finally turned the tide in my battle with skin cancer.
