Cancer signs and symptoms

Cancer symptoms are changes in the body caused by the presence of cancer. They are usually caused by the effect of a cancer on the part of the body where it is growing, although the disease can cause more general symptoms such as weight loss or tiredness. There are more than 100 different types of cancer with a wide range of different signs and symptoms which can manifest in different ways.

Symptoms

Typical symptoms of cancer include:[1][2]

Increased Lactate Production

The Warburg Effect states that cancer cells in the presence of oxygen and glucose take a different path of energy production. Cancer cells are observed to convert glucose in the presence of oxygen into lactate through lactate dehydrogenase instead of traditionally putting pyruvate though the TCA cycle for oxidative phosphorylation.[3] However, cancer cells still carry out oxidative phosphorylation but not primarily for the purpose of energy production but for biomass production through utilizing the intermediates from TCA cycle. This unique metabolism of cancer cells[4] opens doors for possible cancer treatments including targeting lactate dehydrogenase and TCA intermediate production.
