Cancer

Discover supporting research and information on how cannabidiol (CBD) relates to the treatment of Cancer.


Cancer is not a single disease, but instead is a name given to a collection of related diseases. In all types of cancer, abnormal cells in the body begin to divide and grow uncontrollably. Rather than dying, old cells grow into new abnormal cells. In some types of cancer these cells spreading into surrounding tissues to create a mass called a tumor. Not all types of cancer form tumors.

Forms of Cancer

Cancers are named based on the location in the body at which they begin. For example, cancer that begins in the lungs and spreads to the liver is classified as lung cancer. There are several terms used to describe general types of cancer:

Stages

When a person is diagnosed with cancer, they will be given a stage that represents the size of the disease and how far it has spread. A 0-4 stage ranking system is used with 4 being the most severe. These stages are based on a set of specific set of classifications that help determine the treatment path and future outlook:

Causes

Cancer is caused by mutations in the DNA within individual cells. When these mutations occur, the instructions for a cell's activity is changed. When the normal cell function is disrupted by an error, the cell has a potential to become cancerous. These gene mutations can result in rapid cell growth and a failure to stop the uncontrolled growth.


Increased Risk

The following factors can increase the risk of cancer:

Preventative Care

While there is no guaranteed way to prevent cancer, there are ways to lower your risk of the disease by:

Common Treatments & Complications

There is a wide range of cancer treatments available that vary depending on the severity and type of cancer. Some of the most common treatments include:

Different types of treatments often carry a range of complications and side effects that may impact the quality of life of the patient. Complications from treatments include:

Treating Cancer with CBD


A large body of research has been performed on various types of cancer diseases with a wide range of positive results. Many studies have observed CBD and other cannabinoids exhibit a therapeutic effect a reduction of tumor growth via inhibition of tumor proliferation, angiogenesis, and via induction of tumor cell death.

CBD shows promise for the development of new drugs. In some cases, the substance exhibits lesser side effects and more therapeutic benefits as compared to recent available medical therapies. More research and clinical studies are needed to explore the full potential.

A growing body of research is being performed across a wide range of cancer types. See the supporting research section below for type-specific studies.

Managing Side Effects of Cancer Treatments

In addition to the growing wealth of CBD-cancer related research, the compound also has promise for managing the side effects of cancer treatment. Cannabidiol, especially when taken with other cannabinoids in a full-spectrum form or as part of a whole-plant medicine may be helpful in managing side effects like nausea, pain, weight loss and more.

Dosages


25mg of CBD per day to relieve pain in patients with malignant diseases. (General, 3) 300mg of orally administrated CBD per day was given to patients in a transplant test. (Leukemia, 2)
