There are over 200 types of cancer; far too numerous to include in this introductory article. However, the NCI lists several general categories (see list in first section of this article). This list is expanded below to list more specific types of cancers found in each general category; it is not all inclusive and the cancers listed in quotes are the general names of some cancers:


Diagnosing a new cancer in a pregnant woman is difficult, in part because any symptoms are commonly assumed to be a normal discomfort associated with pregnancy. As a result, cancer is typically discovered at a somewhat later stage than average. Some imaging procedures, such as MRIs (magnetic resonance imaging), CT scans, ultrasounds and mammograms with fetal shielding are considered safe during pregnancy; some others, such as PET scans, are not.[219]
However it is important that thiamin (vitamin B-1) be adequate when supplementing with potassium because heart disease can not materialize when both are deficient, but will show up if only one of those is deficient (http://charles_w.tripod.com/kandthiamin.html ). This is probably the primary reason why heart disease is a main cause of death in rheumatoid arthritis patients.

In the 15th, 16th and 17th centuries, it became acceptable for doctors to dissect bodies to discover the cause of death.[186] The German professor Wilhelm Fabry believed that breast cancer was caused by a milk clot in a mammary duct. The Dutch professor Francois de la Boe Sylvius, a follower of Descartes, believed that all disease was the outcome of chemical processes and that acidic lymph fluid was the cause of cancer. His contemporary Nicolaes Tulp believed that cancer was a poison that slowly spreads and concluded that it was contagious.[187]

Cannabis oil extraction is a method to derive THC, cannabinoids and terpene concentrates from raw plant matter to produce a hash or oil, which delivers marijuana consumers a stronger dosage than smoking the traditional bud. The most common methods of extraction use ice water, butane (a petroleum-based product) or CO2 (a naturally occurring inert gas).

In addition, other specialists may be involved depending upon where the cancer is located. For example, ob-gyn specialists may be involved with uterine cancer while an immunologist maybe involved in treatment of cancers that occur in the immune system. Your primary care physician and main oncologist will help you to determine what specialists are best to be members of your treatment team.

Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner.[23][24] In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity.[25] A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC.[26]
Truth be told, one of the biggest draws to using CBD oil for pain has been the fact that it has little distinguishable side-effects or contraindications with other medications. In fact, in a massive report that was published by the World Health Organization during last year’s 2017 Expert Committee on Drug Dependence, it was (finally) declared to the world that CBD is a “safe, well tolerated [compound, which] is not associated with any significant adverse public health effects.”

Some substances cause cancer primarily through their physical, rather than chemical, effects.[63] A prominent example of this is prolonged exposure to asbestos, naturally occurring mineral fibers that are a major cause of mesothelioma (cancer of the serous membrane) usually the serous membrane surrounding the lungs.[63] Other substances in this category, including both naturally occurring and synthetic asbestos-like fibers, such as wollastonite, attapulgite, glass wool and rock wool, are believed to have similar effects.[63] Non-fibrous particulate materials that cause cancer include powdered metallic cobalt and nickel and crystalline silica (quartz, cristobalite and tridymite).[63] Usually, physical carcinogens must get inside the body (such as through inhalation) and require years of exposure to produce cancer.[63]
Cannabis Oil produced and sold by "dealers" can have many contaminants and many times will have minimal amounts or no THC or CBD in them at all. Most of the time cannabis oil available on the street should be avoided for medicinal uses such as treating cancer. It's always better to make your own oil or to have someone you trust make your oil. This helps assure a very pure, high quality oil is obtained. If you know who made your oil, you can better know what you are getting in your oil.

Unfortunately, there is little oversight for manufacturing hemp-derived CBD products, which can lead to confusion and deception. Many hemp-derived products are mislabeled as to CBD and THC content. And poorly processed CBD oil may be contaminated with dangerous solvent and pesticide residues, thinning agents, corn syrup, artificial flavors and colors, and other toxins.

Ethanol extracts available in medical cannabis dispensaries are typically referred to as Rick Simpson Oil (aka RSO) or Full-Extract Cannabis Oil (FECO). In order to make RSO or FECO, cannabis flower is soaked in ethanol, agitated, and strained; then the residual oil is gently heated until all that remains is a viscous, highly concentrated goo infused with cannabinoids, which can be difficult to dose accurately, given how thick it is.


Cannabidiol (CBD) is one of dozens of non-psychoactive cannabinoids found in the hemp plant. Cannabidiol, and all the other cannabinoids, were patented by the United States Government in 2003 as neuroprotectants and antioxidants (Patent No. 6,630,507). Cannabinoids are characterized by their ability to act on the cannabinoid receptors that are found throughout the body. CBD and other cannabinoids are naturally occurring compounds that display potent anti-inflammatory and pain-relieving properties. They can promote the body’s healthy regulation of the central nervous, immune, and endocannabinoid systems.
