The Warburg effect, on the other hand, describes the observation that cancer cells, and many cells grown in vitro, exhibit glucose fermentation even when enough oxygen is present to properly respire. [2] In other words, instead of fully respiring in the presence of adequate oxygen, cancer cells ferment.
In cancer cells, major changes in gene expression increase glucose uptake to support their rapid growth. Unlike normal cells, which produce lactate only when oxygen is low, cancer cells convert much of the glucose to lactate even in the presence of adequate oxygen. This is known as the “Warburg Effect.”
Cancer DALYs attributable to 11 Level 2 risk factors globally in 2019. [128] Cancer prevention is defined as active measures to decrease cancer risk. [129] The vast majority of cancer cases are due to environmental risk factors. Many of these environmental factors are controllable lifestyle choices. Thus, cancer is generally preventable. [130]
Field cancerization or field effect (also termed field change, field change cancerization, field carcinogenesis, cancer field effect or premalignant field defect) is a biological process in which large areas of cells at a tissue surface or within an organ are affected by carcinogenic alterations. The process arises from exposure to an injurious ...
This therapy has shown to work best in conjunction with chemotherapeutics or other cancer therapies. [7] Although the EPR effect has been postulated to carry the nanoparticles and spread inside the cancer tissue, only a small percentage (0.7% median) of the total administered nanoparticle dose is usually able to reach a solid tumor.

The central role of DNA damage and epigenetic defects in DNA repair genes in carcinogenesis. DNA damage is considered to be the primary cause of cancer. [17] More than 60,000 new naturally-occurring instances of DNA damage arise, on average, per human cell, per day, due to endogenous cellular processes (see article DNA damage (naturally occurring)).
Oncology is a branch of medicine that deals with the study, treatment, diagnosis, and prevention of cancer.A medical professional who practices oncology is an oncologist. [1]
Low-dose exposures, such as living near a nuclear power plant, are generally believed to have no or very little effect on cancer development. [74] Radiation is a more potent source of cancer when it is combined with other cancer-causing agents, such as radon gas exposure plus smoking tobacco. [74]
