Hyperbaric Oxygen Therapy and Cancer - An Overview

May 19, 2020
Marisa Soski, ND, MS
One of the hallmarks of solid tumors/cancers is a low oxygen cellular environment, scientifically called hypoxia. (Hypo = low, oxia = oxygen) Hypoxia typically causes cell death, such as in the case of a stroke or pulmonary embolism, but cancer cells have adapted to survive and thrive in these situations. Some of the concerning effects of hypoxia in relation to cancer include:

This belief is starting to change as doctors begin to recognize the importance and role of a healthy diet. On the ...   read more

Improving Immunotherapy with Sodium Bicarbonate

December 12, 2019
Marisa Soski, ND, MS
Cancer cells often adapt and develop new ways of evading the body’s immune system in an attempt to continue carrying on their un-checked growth and proliferation. One way they do this is to express inhibitory receptors, such as PD-1, Lag-3, Tim-3, BTLA, and CTLA4, which help hide the cells from the immune system’s T-cells whose role is to find and eliminate cancer cells. These ...   read more

Within a single tumor, there are a variety of different cell types. One type, called cancer stem cells, or CSCs, are unique because when they divide, they can produce a variety of different cell types in addition to producing more stem cells. This is important because it means that if CSCs are present within a tumor, that tumor has a potential source for any cell type it needs to sustain itself ...   read more
